Renovation of cast iron water supply pipeline - swagelining Łodź 2009

Dąbrowa water supply in Łódż pumps water from Water Treatment Station at Lodowa Street to Stoki Reservoirs at Pomorska Street. The water is accumulated there and then delivered to 1/3 of the city. The refurbishment of the water-main was carried out within contract „Dąbrowa water-main – modernisation of Łódź water supply network” - Part 02C „Dąbrowa Water Supply – Modernisation of the treated water pipeline". The pipeline was renovated under swagelining method. Swagelining is “a tight fit” method which concerns putting PE pipes of temporarily reduced diameters into the damaged pipeline (it takes place by heating the pipes and applying the constant drawing force). After the pipe is pulled the drawing force is released and PE pipe through expansion adapts its diameter to internal diameter of old pipe. This way additional structural reinforcement of repaired pipeline is obtained. The tight fit method was applied in the first section of the water supply pipeline at the exit from the Water Treatment Station, where the highest hydraulic hammering occurs and where the pipeline was used the most, near the passages under a very busy roads (Dąbrowskiego, Przybyszewskiego, Piłsudskiego streets), under PKP tracks and tram tracks.

For this purpose the contractor initially used PE pipes made by X producer, but pulling the pipeline has not been successfully completed. It was immediately decided to change the pipe manufacturer. This time WehoPipe pipes produced by Uponor Infra were chosen. A few days later the pipes were delivered on builing site in 15-metre pipe lengths. Despite the winter conditions, welding went smoothly and pulling of 200-meter section has lasted only 4 hours. Two other sections has been pulled without any problems.

Project: Renovation of Dąbrowa Water Supply of DN750mm diameter under swagelining method Medium: Potable water Scope of delivery: Pressure pipes PE WehoPipe PE100 DA800 SDR17 PN10 – approx. 600 m Additional services: Technical consultations Contractor: Consortium of companies: Infra SA (consortium leader), PBG SA (consortium partner), Wiertmar sp. z o.o.

Sealing of the sewage discharge channel Gdynia Dębogórze 2007-2008

The programme called „Building Water Distribution and Sewage Network in Gdynia, Reda and Commune of Puckˮ is aimed at improving water and sewage management, future ensuring relevant amount and good quality potable water in the entire area covered by PEWIK GDYNIA Sp. z o.o. operation and protecting the waters in the Bay of Puck and resources of the Main Underground Water Reservoir No. 110. One of the problems to be solved concerned the area from the Collective Sewage Treatment Plant „Dębogórzeˮ to the village of Kazimierz, where treated sewage flows in an open channel. Since in autumn and spring the water from the channel used

to flood the nearby meadows and fields, a decision was made to seal the channel by laying a pipeline at the section from the sewage treatment plant to the inlet to the covered channel before the village of Kazimierz. Lightweight, durable and easy to install Weholite PE pipes were used for the pipeline, with the ring stiffness of SN8 and diameters between DN 1400 and 1500 mm, as well as segmented bends and Weho eccentric manholes from Uponor Infra. As the contractor reported, the installation went well without any interruptions, despite unfavourable winter conditions.

Renovation of reinforced concrete sewer Chełm 2013

The renovation included a section of the sewer made from reinforced concrete Ø 1000 pipes of the length of 1291 running metres from Lubelska street to the passage under the Uherka river and a section of Ø 1200 pipes of the length of 155 running metres from the river to chamber K1 of sewage treatment plant „Bieławin”. The renovation was carried out under long relining method with the use of pipes PE-HD Weholite, and the section of Ø 800 sewer running under the Uherka river (2 pipes of total length of 108 m) was renovated under short relining method with the use of PE VipLiner modules. The works were started in January 2013 with the construction of the start chambers and cleaning the inside of the old reinforced concrete sewer. Structural pipes PE-HD Weholite were connected into longer sections under extrusion welding method on the ground surface and were pulled from the start

chambers to their target installation locations. The sections ready to be pulled into the old pipes were 20 to 150 m long. The installation was led in very difficult hydrogeological conditions (muddy soil, high level of ground water and uncontrolled inflow of rainwater) with the existing residential developments along the route of the sewer. The parameters of Weholite pipes such as flexibility, durability and homogeneity of the joints allowed to reduce the number of point excavations and increase the length of the inserted sections. The renovation involving the use of Weholite pipes and VipLiner modules allowed to maintain the continuity of sewage collection (the works were carried out with the operating sewer). In addition this type of technology allowed to handle the small angle bends along the route of the pipeline without the need to make special excavations.

Storm water system for heat and power station Gdynia 2015-2016

The heat and power plant in Gdynia struggled with choking drainage ducts and the resultant elevated level of ground water, which would lead to flooding of the underground levels of the facility. The construction of a classic drainage system using excavation methods was seriously challenged and even impossible in many places due to collisions with numerous underground systems as well as the protective zones of overhead power lines. As a result, a decision was taken to build a new drainage network in the trenchless technology with the use of jacking drainage VipLiner DN 630 mm modules from Uponor Infra. VipLiner drainage modules feature solid polyethylene (PE)

pipes with smooth inner and outer surfaces. Due to their strength characteristics, special technology and geometry of their outer layer grooving, the modules can be used for trenchless drainage systems which lower the level of ground waters. VipLiner 1-metre drain module have slots made using a water jet cutter. 240 slots of 150 mm x 1.5 mm in size are spaced in perpendicular along the axis. Their cross-section has a wedge shape, with the narrower opening at the inner surface. Such cross-sectional geometry creates a natural reverse filter, ensuring that the soil surrounding the drain pipe is not washed away. This world-first method is innovative and patented!

Renovation of airport’s storm water collectors Warsaw, Okęcie Airport 2000 and 2001

2000 The project was preceded by preparations of LOBBE AQUASEWER, which took several weeks. The company inspected the channels located at the airport, assessed their condition and identified sections which should have been given priority. Then the channels were cleaned and necessary installation trenches were made. All the works were carried out during the night not to cause any interference with the airport operation, which was practically unaffected. This was possible due to a schedule of works and ideal cooperation between LOBBE, Uponor Infra and airport staff. The properties of PE pipes and Weholite system considerably facilitated the task and did not cause any inconveniences to the airport traffic.

2001 INFRA was the contractor of the project. Weholite pipes were joined in two 95m long lines. They were transported by means of a truck tractor into the area of runway trench, which is situated outside the airport. Weholite pipeline was introduced through an opening cut in a concrete chamber at the end of the line. The Weholite pipe was passed through the first section of the collector, dn2000 mm, up to the laying area, which was located outside DS-3 runway. Then the next section was introduced. The two lines were joined in a manhole. All works were carried out in difficult winter conditions without any inconvenience to the airport traffic.

Storm water system Płock 2015

The extension of Dobrzyńska Street is part of a larger project "Construction and reconstruction of the road infrastructure of Provincial Roads 559 and 562 in Płock along with essential infrastructure." The project is being realised by the Płock Town Council and it involves extension of the road, sanitary, storm water, potable water, gas, electric and telecommunications infrastructure in the course of Provincial Road 559. This project involves the installation of Weholite SN10 polyethylene piping and Weho manholes made by Uponor

Infra. When extrusion-welded, they make a uniform pipeline which is free from connectors or gaskets. This very safe solution was chosen in an area which has challenging and unstable installation conditions – the storm water system is located in a scarp (Parowa Street/the Brześnica River). Manholes incorporating cascades with welded joints provide leak-tightness at high flow rates and in structures with high inclination of the ground.

Renovation of damaged reinforced concrete collector Wrocław 2003

In July 2003 we started a repair of a damaged reinforced concrete collector of a combined sewage system in Wroclaw. The collector, built between 1970 and 74, is one of the biggest collectors going through the city centre. Its inner diameter is 2.5 m. Renovation was necessary due to poor technical condition of the pipe. Progressing corrosion of concrete, reaching up to 70 mm of pipe wall, i.e. over one third of its total thickness, was visible along the whole length of the collector. A 231 m length was repaired by means of short relining, which involves introducing polyethylene Weholite modules inside the damaged collector. Weholite pipes were supplied in 6 m and 3 m lengths. It allowed us to minimise the dimensions of the starting chamber and reduce the problems connected with traffic.

Weholite technology made it possible to maintain continuous sewage water discharge. Installation works were performed on an collector in full operation. Relining in Weholite technology guarantees: leaktightness long service life no corrosion easy and quick completion of works Thanks to Weholite technology it was possible to overcome bends without trenches (9 and 16°) by fitting the length and shape of Weholite segments to the curve of the collector. Weholite lengths pulled into the collector were welded inside the bend. The empty space between the old collector and Weholite modules was filled with cement-ash mixture.

Collectors for sewage treatment plant Warsaw 2005

Nineteen kilometres of polyethylene pipes with diameters of 1000 mm and 1400 mm connected the southern area of Warsaw with „Południeˮ sewage treatment plant and the Vistula. A part of this complex investment was conducted using an open excavation method, and the entire route under Czerniakowska Street and the passage under Augustówka Street was done with microtunneling. Sewage from several districts of the southern part of the left bank Warsaw is discharged to the new sewage treatment plant. To allow for the Warszawa Południe sewage treatment plant to perform its function it was necessary to build a system of feed and discharge pipelines. It required building the main sewage pipelines connecting the sewage treatment plant to the Warsaw sewage system and use sewers to discharge the treated sewage to the Vistula. The construction of supply and intake sewers was divided into two simultaneous tasks. The first one covered construction of three parallel pipelines between Wolicka pumping station and Warszawa Południe sewage treatment plant. The route of the pipelines (3 x 5 340 metres) mainly crossed green areas and

wasteland, that is why the majority of works involved open excavation. The other task - 3712 m long pipeline, runs under Czerniakowska Street. The entire part was completed by microtunneling. The acquired method did not entail banning vehicle traffic on the whole Czerniakowska Street during the works. The polyethylene pipes were installed in reinforced concrete pipes laid under microtunelling method. Uponor Infra provided pipes with the total length of 19,641 m. The pipes are made of polyethylene and have very good functional characteristics. They are failure-free, resistant to corrosion and abrasion. PE pipes are joined by welding subsequent sections. It provides a great advantage since such technique of joining ensures not only complete tightness but also excellent durability of the entire pipeline, including the joints. It is worth emphasising that using polyethylene pipes helped avoid a number of costly bends and fittings, due to the possibility of the pipeline shaping in the trench.

Sewage and storm water system Chorzów 2011-2012

The project assumed the liquidation of the exiting worn out sewage network in the designed area and the construction of new main distribution sewage network, i.e. the sewage network and storm water system including the necessary connections of the existing sewage network. The works were carried out in a very difficult area at very big depth reaching occasionally 10 m. The unfavourable water-soil conditions, the area affected by the impact of mining operations and the dominating narrow excavations required the use of high quality materials and extensive experience of the contractor.

Renovation of damaged concrete collector Legionowo 2005

Short relining with the use of VipLiner modules dn560 of WIPRO type collector of total length of 425 m. The collector was constructed in the nineteen seventies and transports municipal sewage (it works as the expansion collector) mainly from the sewage catchment point including side inflows from residential buildings. Due to the high content of hydrogen sulphide and other aggressive compounds in the vapours, the deep corrosion of upper part of the pipes occurred, leading sometimes to local loss of stability of the pipes. The only feasible renovation method concerned the excavation-free method with the use of short modules VipLiner, which form autonomous sewage pipe of high circumferential rigidity (SN8), and are not e.g. just a lining. The installation of the modules was a very easy task

– it was conducted directly from the existing sewage manholes without the need to disassemble the slabs covering the manholes – modules dn560 mm were inserted through the opening of manhole lid (600 mm). Due to the local subsidence of the collector it was necessary to use the modules made from the material resistant to cracking, e.g. as a result of the potential striking against concrete debris of the collector during the installation works – these requirements are excellently met by polyethylene modules VipLiner. The complete subsidence of the existing collector occurred in a few sections of the renovated duct and the modules were pushed in these places under the tunnelling method.

Renovation of a damaged stoneware collector Tomaszów Mazowiecki 2014

A decision was made in 2013 to carry out renovation of the stoneware collector of diameter dn250mm and dn400mm. The collector was leaking in numerous places and in the places of its connection with the manholes. Upon analysing various renovation technologies it was resolved to repair the collector with the use of VipLiner polyethylene modules PE100 RC of increased resistance to propagation of cracks, point pressure and result of scratching, Blejkan applied the static cracking method, which concerned the crushing of the old collector with the use of the head connected by steel bolted poles with the hydraulic drive hoist and parallel insertion of VipLiner modules after the head.

This method allowed to improve the hydraulic parameters of the sewage network. Uponor Infra delivered for the purposes of this investment the modules of 0.5 m length and diameter respectively higher than the renovated section (dn355 and 450mm). The works were carried out in winter at the turn of 2013/2014. The renovation included 8 sections and the longest section between the manholes was 60 m. The contractor commended the easy and simple nature of installation of the modules and the speed of works using VipLiner modules (the average renovation time of a section is approx. 3 days).

Horizontal drilling under the Martwa WisĹ&#x201A;a River GdaĹ&#x201E;sk 2000

15m lengths of PE pipes dn 1200mm were butt-welded into one line of total length of 530m. PE pipeline was introduced into a specially prepared tunnel drilled under the bed of the Martwa Wisla River. The installation opening had a diameter of about 1.8m. As it was shown beforehand in a geological analysis, installation conditions were very difficult.

The installation works were completed within 18 hours. The pipeline laid under the Martwa Wisla River bed was connected with a land collector by means of two pumping units built on both sides of the Martwa Wisla. The drilling in Gdansk sets a European record for the length of a pipeline of such a large diameter.

Horizontal drillings under the Odra river Szczecin 2006-2008

In 2007 in Szczecin, a series of record-breaking in the European scale number of crossings of a high dimension pipeline under a water obstacle made with a horizontal drilling method was completed in Szczecin. The engineering work was done within the "Improving water quality in Szczecin" programme. The contractor scheduled using 3 different pipeline founding technologies: open excavation, microtunneling and horizontal drilling, where 6 largest crossings under water obstacles with the total length of over 3 km was done without excavation. The open excavation and microtunneling technology used standard PEHD WehoPipe pipes with DN 1000 x 59.3 mm PN 10 SDR 17. In the tunnels made by horizontal drilling, due to very hard geological conditions and founding at the depth of ca. 20 m, pipes with thicker outer walls were applied (dzxe 1033.2 x 75.9 SDR 13.6 MOP 12.5). The pipes were produced and delivered to the site in 15-metre sections to minimise the number of welds on the pipeline course.

In December 2006 after making pilot drilling, the first actual drill was made at the Customs Office. 460 and 465 m long sections were pulled into the drill under the Oder. The pipeline sections under the Parnicki Canal - 360 and 570 m long were founded in February 2007. With regard to a lack of space to mount the pipeline near the crossing, they had been welded on the Pucka Island, launched and transported by tugs to the site. In the case of the shorter section the whole pipe was pulled out of water and placed on rollers. The longer section was almost entirely pulled directly from the canal. It is worth noticing that it was the first in Poland installation of such a large polyethylene pipe transported and mounted almost completely from water. The pipelines were founded at the level of Pucka Island between March and April 2007. 620 m and 626 m long pipes were installed, breaking a new European record in the length of a large-dimension pipeline pulled into an HDD drill.

Drainage systems around Żelazny Most tailings pond KGHM Polska Miedź S.A. 1997-2015

Tailings pond „Żelazny Most” is at present the only location for storage of the post-flotation waste for all mines of KGHM Polska Miedź SA, which makes it a key technological link. The water circulates continuously in a circuit between ZWRs (Ore Enrichment Facility) and the storage facility. The current length of the barriers surrounding the tailings pond is 14,3 km and the total size of the facility is - 1394 Ha. The annual volume of deposited flotation waste ranges from 20 to 26 million tonnes. In addition to a primary function, i.e. the waste disposal, the reservoir created in the central part of „Żelazny Most” storage facility serves at the same time the function of the settling tank clarifying the sludge supernatants used in the flotation process,

and due to high capacity serving also the function of a retention reservoir dosing the excess mine-process water in the circulation. The area of the barriers and on its foreground has in place the drainage systems, perimeter ditches along the barrier, which intercept in total approx. 80% of the infiltrating water. The use of pipelines made from the materials representing the best parameters (chemical resistance, abrasion resistance, uniformity of connections, speed of laying) plays an important role in such extended and highly complex industrial facility. PEHD pipelines produced by Uponor Infra (former KWH Pipe) proved their quality in these conditions. In addition to the pipelines, Uponor Infra also delivered the manholes.

Transport of post-flotation waste – process pipelines KGHM Polska Miedź S.A. 2000-2015

KGHM Polska Miedź SA – is one the largest copper and silver producers in the world. The raw materials base of KGHM Polska Miedź S.A. includes the copper ore deposit, which is largest in Europe and one of the biggest in the world. The mining areas of the size of approx. 468 km² were created for the purpose of its mining. KGHM has in place its own integrated production structure, which includes three mines (ZG „Lubin”, ZG „Rudna”, ZG „Polkowice-Sieroszowice”), three copper smelters („Głogów", „Legnica”, „Cedynia”), and branches supporting the core activity (Ore Enrichment Facilities. Hydrotechnical Facility).

The Hydrotechnical Facility is responsible for storage and management of the waste created during the production process. The basic tasks of the Facility are related to the water-sludge management of three Ore Enrichment Facilities, which conduct the copper ore mining output enrichment operations under a flotation method. The post-flotation waste is a liquid sludge, which is transported via pipelines to Żelazny Most storage facility. The solid phase sedimentation process takes place at the storage facility and the cleaned water is collected and re-directed to the Ore Enrichment Facilities.

Transport of post-flotation waste – process pipelines KGHM Polska Miedź S.A. 2000-2015

The first deliveries of PEHD pipelines for sludge transport - d.800 PN12,5 – were executed by Uponor Infra (former KWH Pipe) in 2000. PBH Odra 2 was the contractor in this investment. This investment concerned crossing of the over under the submerging method. The length of the submerged section was 168 m. Another interesting investment executed at Hydrotechnical Facility concerned the delivery of pipelines d.710mm SDR17,6 for Pebeka S.A. This investment concerned renovation of steel sludge pipeline d.813mm with the use of PEHD pipe under the long relining method. The longest section of the pipeline inserted under a single operation was 1000m.This was a record, which allowed the Contractor to receive Limbur award in category: Project of year 2002 - Renovation. The investments regarding steel sludge pipelines under PEHD technology of Uponor Infra were carried out during the subsequent years. It is worth highlighting the investment carried out during the years 2008-2009 jointly with PPU MONT-INSTAL from Polkowice, under which pipelines PEHD d.900 PN10 were installed on the existing high

supports. The entire investment included the laying of approx. 2.5 km of the pipeline. The biggest investment executed to date at Hydrotechnical Facility concerned the investment executed jointly with Tolos from Żory, which concerned laying of the double line of PEHD pipelines of following parameters: d.1000 SDR11 PN16 - approx. 2,5km d.1000 SDR21 PN8 - approx. 1km d.1300 SDR17 PN10 - approx. 2km d.1370 SDR17 PN10 - approx. 1,4km Another investment executed during the years 2014-2015 included the delivery of pipelines d.1250 SDR17 PN10 (approx. 1,5 km) and d.1290 SDR13,6 PN12,5 (approx. 3km).

• • • •

The broad application of PEHD pipelines for hydrotransport of the sludge results from their exceptionally high abrasion resistance. In 2009 KGHM Polska Miedź inspected PEHD pipelines after over 10 years of their operation. It turned out that the wear of the pipeline was marginal and even the internal pipeline fins have not been worn out.

Transport of sludge supernatants – process pipelines KGHM Polska Miedź S.A. 2012-2013

The current positive experiences of KGHM Polska Miedź S.A. with transport of post-flotation waste determined the decision to use the PEHD systems also for the transport of sludge supernatants from the post-flotation waste tank. The decisive advantage of PEHD systems concerns their reliability and ability to support longitudinal loads, which has a special significance in the case of pipelines installed in the area of „Żelazny Most” facility. The first installation of this type concerned the construction of pipeline DN1500 PN10 of the length of 2310m, which despite difficult conditions and installation during the winter period, was completed over a 4 month period.

Transport of sludge supernatants – process pipelines KGHM Polska Miedź S.A. 2012-2013

Another investment concerned a prototype installation related to the modernisation of sludge supernatant intake located within the basin of the post-flotation waste tank. The water intake towers is equipped with siphon intake, which takes water directly from the reservoir. The location of the intake in close vicinity of the discharge points and embankments surrounding the reservoir caused the need to find a solution, which would allow to intake water of appropriate cleanness. In order to ensure the better cleanness of water collected from the tailings pond through intake „E”, it was resolved to extend the supply section by pipeline PEHD DN1200

of the length of 600m for the purpose of taking water from the area of bigger depth and distance from the silting deposits. The inlet is suspended to a float with the option of adjusting the position of the overflow edge below the water level in the tailings pond. The floating pipeline is stabilised on surface of the reservoir by the anchors. All works related to connection of the pipeline were completed during 14 days, while the process of submerging the pipelines itself was completed during 48 hours. The aforementioned solution was a prototype solution and as it met completely he expectations of the Investor, a similar installation is planned for subsequent water intakes.

Renovation of the sewage collector from the cellulose plant Ostrołęka 1996 i 2003

A pipeline transporting post-process sewage from the Cellulose Plant to the biological sewage treatment plant runs under the streets of Ostrołęka. The transport of sewage was taking place since 1995 via steel pipeline, however due to aggressive nature of the sewage, the corrosion quickly occurred. A part of the pipeline was repaired by making a reinforced concrete casing. Still the further corrosion was occurring, the breakdowns and local leakages into the soil were taking place. The Investor decided in 1996 to repair 1726 m long end section under long relining method with the use of pipes Uponor Infra (former KWH Pipe). The company offered to execute the entire project on turn-key basis. The repair works were conducted from 8 installation trenches. The lengths of the inserted pipes ranged from 160 to 370 metres in a single section.

The Investor resolved in 2003 to carry out another stage of renovation of steel pipeline of 3285 m length. Uponor Infra delivered the pipes and welding machines. The situation was more simple compared to the 1996 renovation – this section did not have the reinforced concrete casing of steel pipeline. In addition a decision was made to resign from the inserts and connecting the inserted pipes with flanges - the connection of the pipes with the use of electrofusion couplings boxes was used in the excavations. The occurring bends were handled by using the option of bending PE pipe resigning from segment bends. The pipeline was tested in 8 sections and under a final test of the entire renovated pipeline. The renovated pipeline works without any problems transporting chemical substances.

Transport of brine – technological pipelines PGNiG - Underground Gas Storage Kosakowo 2009 The extension of underground gas storage facilities is very important from the perspective of Poland’s gas security and thus for a number of years has been one of investment priorities of PGNiG. KPMG Kosakowo is the first underground methane-rich content gas storage facility in northern Poland constructed in rock salt bed. The gas will be stored in adapted salt chambers at the depth of 1000 to 1200 m. The completion of the entire investment is planned for 2020 and as of 2014 it will be operating with capacity of 100 million m³. The construction of target ten storage chambers of total capacity of 250 million m³ will involve excavation of 3.4 million tonnes of salt in the form of a brine of approx. 18 million m³ volume.

The storage chambers are created by salt leaching with the use of water pumped into the salt bed. This process results in the formation of a brine, which should be managed or discharged in a safe manner into the reservoir. As of 2009 this brine is discharged through pipeline WehoPipe PE DN 355 into the Puck Bay. A system of diffusers was installed in the distance of 2.3 km from the shore at 8m depth, which allows to control the distribution of the brine in the Puck Bay waters. The current failure-free operation of the brine pipeline confirms the suitability of PE system to such demanding and high-level applications.

Construction of raw water pipelines for the power plant Kozienice Power Station 2015–2016

Enea Group is a leading producer, distributor and seller of electric power and heat. It is the third largest energy company in Poland, with a 13% share of the Polish electric power market. The party responsible for power generation within the Group is ENEA Wytwarzanie S.A., which operates Elektrownia Kozienice, a fossil-fuel power station with 10 high-duty power units and a cumulative generating capacity of 2,919 MW. Due to a growing demand for electricity and need to curb emissions into the atmosphere, a decision was taken to build an 11th plant at the Kozienice Power Station, with a capacity of 1075 MW (gross). It will be the most modern coal-fuelled unit in Poland and Europe, operating within supercritical parameters, enabling it to generate the same amount of energy with much lower coal consumption. An essential element of the new plant is a raw water pipeline which feeds the water treatment plant. The facility will comprise several elements:

–a gravity pipeline for mechanical transport of pre-treated water from a cold water intake to the raw water pumping station, where Weholite DN 1000 SN 8 piping will be used as well as Weho DN 1800 inspection manholes for maintenance purposes – t wo raw water intakes from the existing canal that supplies cooling water from the Vistula River to the pump station of the 500 MW plants, where pressure pipes were used. The first section of the pressure pipeline PE 100 PN 7.5 SDR 22, size 800 x 36.4 mm, length 405 m, was laid in a trench. The installation of the other section called for trenchless technology – a method of horizontal directional drilling (HDD). The drilling was made using PE 100 PN 10 SDR 17 pipes, size 800 x 47.4 mm.

Construction of cooling system for the power plant Fosur-Mer, Francja 2009 A power plant with combined circulation CombiGolfe of 420 MW capacity is already a third Project carried out by Alstom in collaboration with Uponor Infra. Weholite pipes were used to construct the cooling system and water discharge system. Weholite pipes offer a number of advantages: are flexible and adapt well to the dynamic environment, are light and can be quickly installed. In addition they do not corrode, which is a key factor in respect to their installation in salty water, and their profile can be filled with e.g. with non-hardening (liquid) cement mortar. Two 210 m long pipelines made from Weholite ds2200mm SN4 pipes were used for water intake in the cooling system and these pipes were delivered from a factory in Kleszczów in 13.3 m long sections. The pipes were welded on land and Weholite profile was filled with non-hardening (liquid) cement mortar.

All works (including the welding and filling of the profile) were completed within approx. 5 weeks. The ready welded sections were launched into water with the use of self-propelled cranes and towed to the power plant. Upon filling the profile they were submerged and placed in the earlier prepared excavation. The external ends of the pipeline were installed 16m under water surface. Weholite dn2400mm of the length of 840m and 45° and 90° bends and T-ways made from Weholite dn2400 mm/1800 mm pipe and inspection chambers made from WehoPipe dn1000mm pipe were used for water discharge. The pipes were welded into 3 sections, which were subsequently placed in the prepared excavation leading from the power plant to the sea. The transport of each of the sections involved the use of 12-16 self-propelled cranes. The works were completed in May 2009.

Construction of derivation pipelines for MEW Cieszyn 2011

A construction of small hydropower plant in Cieszyn of 0.56 MW capacity was started in October 2010. The plant uses the gradient of Olza river. The derivation pipeline used to transport water from Olza river to the power plant was constructed in Uponor Infra technology. The low-pressure PEHD Weholite DN2200 pipes were used representing the total length of 510 m. The advantage of the adopted solution concerns the lack of canal maintenance costs and high reliability and energy effectiveness. The other advantages include: uniformity of connections pipe sections and fittings, 100% tightness of the entire system, Easy installation irrespective of the weather conditions (also in minus temperatures), Very small weight of the pipes compared to traditional materials, Very high resistance to abrasion,

• Small speeds of impact wave propagation for hydraulic

hammering (a few times smaller compared to steel, cast iron or GRP). Low costs of installation and maintenance compared to other technologies, Complete resistance to stray currents, Very low and long-term absolute roughness coefficient. Despite difficult weather conditions and restricted accessibility to the site, the works were carried out very efficiently. The pipes were connected under automated extrusion welding method (using machine WLI 3000). The option of bending the pipeline allowed to resign from the use of the segment bends and support blocks, which significantly simplified and accelerated the execution of the project. Uponor Infra technology allows to prefabricate complex fittings, e.g. T-way with inlet DN 2200 and two outlets DN 1600, whose task is to divide the water stream between two turbines.

Passages across the river Krapkowice 1997, Brzeg upon Oder 1998 A passage across a river or lake is typically achieved by laying a specially selected pipe (pressure or gravity type) on its bottom. This is an economical solution for a failurefree system with a minimum green footprint. In the past, underwater pipelines were built of steel, but today such systems are made practically solely of PE. A submerged pipeline must be resistant to corrosion and hydrodynamic forces that occur under water. In 1997 the first passage was made across the Oder River using a pressure pipeline which was freely submerged. That was but one upgrade of the wastewater treatment plant in Krapkowice. The considered options were to build a pipeline bridge or to suspend the pipeline under a railway bridge. Ultimately, it was decided to employ an original solution

proposed by Uponor Infra (former KWH Pipe). Welding and submersion of the river section took place in the spring of 1997 and it lasted 2 days. Uponor Infra also supplied other products that were essential for the construction of technological pipelines and connections between wastewater treatment facilities. Three months after the pipeline was submerged, both the railway bridge and the heat bridge were destroyed by a flood, while the pipeline was safe on the river bed. Also, all other pipelines made of PE were intact. A year later in 1998, a 170-metre-long pipeline to supply municipal waste to the wastewater treatment plant in Brzeg was installed using the free submersion method. Uponor Infra supplied Weholite DN 700 SN 8 gravity piping.

Sea outlet of treated sewage Gdańsk 2001

Submarine pipeline - sea outfall is part of the largest ecological investment in the Baltic Sea area. The project is connected with an extension of „Gdansk-Wschodˮ sewage treatment plant and discharge of the treated sewage water into the sea. The discharge pipeline consists of a 2.5 km length of PE dn1600 butt-welded pipes. The pipes were joined on the bank of the Martwa Wisla River and were put directly into the water. In this way three sections of the pipeline were prepared, each 830m long. Concrete blocks, attached onto the pipeline, facilitated the sinking operation.

Project: Sea outfall Medium: Treated sewage water Scope of installation: WehoPipe pipe PE dn1600 SDR26 PN5 length - 2500 m Additional services: Agreement of technical documentation, design calculations (partly), training of contractor's staff in the field of installation of the pipeline, welding of the pipeline with KWH Pipe (Uponor Infra now) machines, supervision over sinking operation (free sinking on the bed of Zatoka Gdanska (Gdansk Bay) Contractor: Hydrobudowa Gdańsk Sub-Contractor: PRCiP Gdańsk 4 8 | Reference Projects - Underwater pipelines

The weight of the blocks was so designed that the collector, filled with water, was safely placed on the riverbed. Three floating pipeline sections were joined into one line. Sinking (laying) of the pipeline on the bed of Gdansk Bay was carried out at the end of 2001. Thanks to the co-operation of the contractors, i.e. Hydrobudowa and PRCiP of Gdansk with the Uponor Infra specialists, the whole operation took only a few hours.

Sea outlet into the Black Sea Cayeli, Turkey 2002

A construction of underwater pipeline in the Black Sea, submerged at the depth of 3000 m below the sea level, was carried out in 2002. The 3000m long pipeline is used to discharge post-process wastewater from the copper and zinc mine in CayelI in northern east Turkey. The Investor, Cayeli Bakir Isletmeleri AS (CBI), selected Uponor Infra (former KWH Pipe) to execute the investment, which a few years earlier has delivered and constructed in this area a first pipeline of that type. Uponor Infra is the global leader in the production of PE pipes and experienced specialist entity in the area of execution of underwater projects. Due to environmental protection reasons, the outlet of the sewage was submerged at the depth of 300 m, i.e. below the biological life zone. The solution proposed by Uponor Infra was selected not just

because of the extensive references of the company, but also because of the properties of PE: 100% resistance to corrosion Very high abrasion resistance Long operating period Flexibility and absolute tightness of the joints The pipeline consists of the main pipe for the transport of sewage and a float pipe, which served the function of the displacement tank for the period of assembly and its submersion. Both lines of the pipeline were connected with each other with the use of the especially designed reinforced concrete weights spaced every 6 m. The pipes were produced by Uponor Infra and delivered to Turkey in 15m long sections. The pipes were connected with the use of Uponor Infra welding machine.

Retention sewage canal Rzeszów 2014

The first implementation of retention sewage canal solution took place at the turn of 2014 and 2015 in the area of intensively developing residential district Krakowska South in Rzeszów. The purpose of the newly constructed retention canal is to reduce the temporary outflow of storm water from the new catchment to the existing open drainage system, which has reduced hydraulic capacity. The construction of the retention sewage canal was envisaged in two stages. The first completed stage of the investment concerned the construction of retention canal of the total length of nearly 140 m including the collectors draining the side roads and pavements. The second stage concerns the construction of retention canal of the length of 160 m including the supplementary networks. The total scope of works concerns the construction of the drainage network of the length of 1.5 km within the diameter range DN 200÷2400 mm and ring stiffness SN 4÷12 kN/m² including the facilities pre-treating the storm water sewage.

Sewage separation system Polkowice 2012-2013

Construction of storm water collectors at Przemkowska street in Nowe Polkowice is one of the stages of a big investment concerning the drainage of the district. Uponor Infra was a supplier of pipe systems PEHD Weholite SN8 within the diameter range dn 500÷1600mm. The storm water separation system was constructed in collaboration with NavoTech Inżynieria Środowiska. In the course of execution of the project the heavy and complex structures of concrete separators were replaced with the modern system of separation and pre-treatment of storm water in Weholite technology of diameter dn 3000mm. Uponor Infra produced and delivered also the Weho manholes, which supplement

the pipe systems. The application of unique technology of Weholite pipes and connection of elements of the manholes and pipes with the use of extrusion welding ensures their high quality and 100% tightness. Thanks to small weight the Weho manholes are easy to transport, unload and install. The manholes are delivered to the construction site as monolith structures with factory made connections, which allows to save the assembly time at the construction site and thus reduces the construction costs and ensures exceptional durability of their operation. The system was started up and released for operation in February 2013.

Roads – relief of the viaduct structure Grudziądz 2007, Białystok 2010 and 2012

Grudziądz 2007 Increasing traffic problems in the centre of Grudziądz forced the city authorities to make a decision on building a road combining the southern and northern part of the city – Trasa Średnicowa. Using PE pipes at building the service road viaduct resulted in relieving its construction and reducing costs of the investment. Choosing PE pipes was an innovative solution applied by the authors of the project. Previously this kind of constructions used steel pipes that were heavier and subject to destructive impact of environmental factors and chemicals. Weholite pipes were a perfect solution. Lightweight, tight, extremely durable and easy to install, not only did they relieve the construction but also eliminated the problem of corrosion. KWH Pipe (Uponor Infra now) produced and delivered to the site almost 900 m of Weholite PE pipes with the ring stiffness of SN2 and diameters between DN 600 and 800 mm, which already in the factory were precisely adapted to dimensions of the spans and viaduct reinforcement system. Weholite pipes were stopped at both ends and placed in the viaduct structure between the reinforcing rods. Subsequently they were secured by closing reinforcement and covered with concrete mixture. Project 1: Relieving construction of the service road viaduct in Grudziądz Medium: Stay-in-place formwork Scope of installation: Weholite pipes SN2 DN 600 - 800 mm, sections from 406 to 676 mm long, total - 886 m Contractor: Mosty Łódź S.A Investor: City of Grudziądz

Białystok 2010 and 2012 Three subsequent viaducts were constructed in Białystok during the construction of Generalska Route forming a part of the city ring road (two in 2010 and one in 2012), which used PE pipes as the structural relief. Uponor Infra delivered to the construction site over 6km of Weholite pipes SN2 dn700mm in sections, which were adapted at the factory to the dimensions of the spans and viaduct reinforcement system and stopped at both ends. Similar to Grudziądz project, upon the installation of the pipes in viaduct structure and securing them with the closing reinforcement the pipes were covered with the concrete mixture.
