FIELD RESEARCH ON GROUNDWATER PROBLEMS IN AL-KHALIFA Mapping roundwater problems in al-Khalifa
Sections showing the street, monuments, and water levels of these areas
Groundwater inundation appears in 11 places along al-Khalifa Street. It is due to the street’s altitude which is lower than surrounding areas. In most cases these are places lower than the street level (monuments/basements). The most critical case is the two domes of al-Ashraf Khalil and Fatima Khatun in which there is an inundation of water approximately 40 cm above their floor level. Local residents account the rise in groundwater to the construction of Zaynhum Housing west of the site. Pisometers were drilled east and west of the domes to ascertain the height, quality and quantity of water. Building on calculations from the dewatering system in Ahmad Kuhya Mosque, Potential amount of water from dewatering the two domes is 850 m3/day.

MAPPING URBAN WATER FLOW IN AL-KHALIFA USING URBAN METABOLISM INFORMATION SYSTEM Workshop | 23-25 Sep 2016 | in partnership with Eco City Builders and Cairo University | 35 participants [architecture and planning students + fresh graduates] UMIS methodology The Urban Metabolism Information System (UMIS) calculates the flows of water, energy, materials, mobility and ICT through the city. It tracks the flow through five phases; source, upstream, demand, downstream and sink. For example the source of water can be rivers, ponds, rainwater, ground etc. the upstream can be the city water company, ground well, etc., Demand can be the uses; toilets, drinking, laundry, etc. Downstream can be the waste water treatment plant and the sink can be rivers, sea, ground, etc. The system then maps the amounts and types of different flows, it is also capable of mapping leakages and looping (reuse). This workshop studied the water flow in al-Khalifa area. Representative archetypes were chosen to cover different patterns of water use in the area. The types were as follows:
Residential
Educational
Commercial – High use
Commercial – Low use
Religious
Educational
Result Source, demand and waste were calculated for the 6 archetypes. Relatively high water use for public (religious + educational) buildings renders them the most likely candidates for pilot projects/ highest The combined result (left) showed that loss (water unaccounted for and probably lost due to leakage from the supply or waste network) was at least 25%. Other Outputs Brainstorming session concerning ideas for extraction, treatment and reuse focused on the following:

KHALIFA HERITAGE PARK | STRUCTURAL STUDY + DESIGN FOR INFRASTRUCTURE AND GRADING Athar Lina team | submitted to Cairo Governorate for Technical and financial approval in March 2017
The node of al-Ashraf Khalil and Fatima Khatun domes and the ½ feddan ridge opposite was targeted due to the following: 1.
Field observations indicated that this was the most critical area with heritage stes and residential buildings at risk from settlement and innundation due to water coming mostly from nearby Zaynhum Housing which is c. 8 M higher.
2.
UMIS findings that there is loss of water due to seepage and recommendations for integrated solutions that link dewatering of heritage sites to adjacent open spaces where a percentage of the extracted water can be treated and resued.
3.
Needs assessment study that indicated: a. the need for green public space geared towards families (partcularly women and children); b. the capacity of the ridge to function as a magnet for local visitors to al-Sayyida Nafisa Square and briing them into the neighbourhood; c. the potential for job creation through introduction of shops along the streetline and cafeterias in the park – also a means of economic sustainability for the project as a whole.
The project brief of a mixed use park with a heritage and environmental awareness mandate resulted in the conceptual zoning detailed below, based on which a structural and grading study was prepared.

ABOUT ARCE CONSERVATION SCHOOL | GROUNDWATER AND SALT DAMAGE TO HISTORIC SITES IN URBAN CONTEXT School | 13 Nov – 22 Dec 2016 | in partnership with Oregon, Cornell, TU Delft and Cairo Universities + Takween ICD | 30 participants [Government] + 20 auditing [conservation and architecture professionals & students] A six week conservation school aimed primarily at Ministry of Antiquities employees. It engaged a total of 30 employees of MoA in addition to representative participants from Cairo Government, the Ministry of Housing, and the Water and Sewage Companies. Students and young professionals were also given a chance to audit sections of the course. Teaching was through lectures, fieldtrips, practical exercises, discussions and peer exchange with a side program of public events. All the course activities took place in alKhalifa generally with focus on the domes of al-Ashraf Khalil and Fatima Khatun as a case study. The aim of the school was to introduce an interdisciplinary group of heritage, conservation and built environment professionals to the latest theories, methodologies and practices for treatment of problems related to rising damp and salt damage in historic contexts. The school also introduced the integrated approach of contextualising traditional conservation practices within the larger picture of urban upgrades and socio-economic development.

Integrated Solutions Module 7 | 18-25 Dec Proposals for pilot projects for water extraction and reuse within historic contexts
After site visits to understand dewatering systems and water treatment systems, the team focused on devising integrated solutions to the water problem in al-Khalifa. The teams worked in three steps, first through general ideas then through strategies on the area level then interventions on a specific site level. Through the three steps, focus was always on the three aspects of the problem of water scarcity, prevention, treatment and reuse. The proposed interventions then were evaluated according to the following goals of the project:
The significance of the historic fabric and the importance of cultural heritage. The need for livability and thermal comfort. The desirability of economic enhancement/activity/redevelopment. The importance of anticipating potential impacts of climate change.

KHALIFA HERITAGE AND ENVIRONMENT PARK | INTERNATIONAL SCHOOL FOR INTEGRATED SOLUTON TO GROUNDWATER PROBLEMS Workshop | 28 Mar – 8 Apr 2017 | in partnership with Cornell and Oregon Universities and Takween ICD [25 participants [architecture; planning, environmental design, heritage, structure; landscape design; hydraulics] ABOUT THE SCHOOL Interdisciplinary-minded students and young professionals work collaboratively to develop innovative design solutions for a proposed Heritage and Environment Park on al-Khalifa Ridge overlooking al-Ashraf Khalil and Fatima Khatun Domes. Design proposals addressed goals of enhancing public open space, empowering community, fostering environmental awareness, celebrating heritage, stimulating economic activity, and improving accessibility and climate. Teams examined techniques for converting groundwater present on the site from a liability to an asset that will provide functional and aesthetic benefits to the park and neighborhood. These dewatering strategies are intended to have applicability beyond Khalifa. In addition, after developing the design, part(s) of it will be piloted.

2. HERITAGE TEAM [Mariam Dawoud, Sandra Fruehbing, Shimaa Osama, Mohammed Nagy]
Main ideas for linking Khalifa’s heritage to environment
The Nile as a natural heritage bringing water to and to the citadel via the aqueduct. The legend of the landing of Noah's Ark on Jabal Yashkur, where the mosque of Ibn Tulun is. The Nilometer and celebratory processions going to it going through al-Khalifa St. The Euphrates River in Iraq, Ibn Tulun’s homeland. According to a hadith, both the Nile and Euphrates stem from paradise. Khumarawayh ibn Ahmad ibn Tulun built a garden that stretched to the citadel. "Ibn Tulun's son Khumarawayh … took special care of the garden of rare flowers and trees. Tree trunks were coated with gilded copper from which pipes trickled water into canals and fountains to irrigate the garden, and nearby was an aviary with singing birds. Most remarkable was a pool of mercury, where Khumarawayh, an insomniac, lay on an air mattress trying to rock himself to sleep. The entire complex, with its gardens, huge stables and menagerie of wild animals, did not overlook the Nile but rather the Birkat al-Fil, a large pond connected to the Khalij." (Abouseif, Islamic Architecture in Cairo: An Introduction, 1989) The street was called al-Mashahid (the shrines) because of the large number of shrines dedicated to descendants of the prophet, this can be built on for the development of religious tourism and heritage awareness.
Design Ideas
Forest like area (climbing forest) where kids can get rid of a lot of energy very quickly so they move and get tired.
Ephemeral Gravity wall: where the kids can draw with water and then the draws will disappear after awhile
Cross-cultural activities: Links between Egyptian, Indian and European cultures for example: in Arabic writings, we use the Indian numbers and Europe use Arabic numbers so this could be represented on the wall of the café. Another example is tea-drinking traditions in Egypt and teas come originally from India. Can be connected to planting mints or the cafeteria.
Use Islamic patterns in design.
A Selfie Spot in a location combining both heritage and nature, maybe leading to a crowd-sourced interactive online exhibition.
"The wall of expressions" continuing the tradition of graffiti observed in Egypt from Pharaonic times. The tree of pearls: inspired from the story of Shajar al-Durr e.g. planting a big tree on the main entrance of the park that looks like a tree with pearls. Nile wetlands: Water greenery setting (Nile wet lands) to reflect the idea of the Nile as a cultural heritage element.
Magic water feature: Inspired by the water figure in the plates of al-Kritiliyya House as a mosaic work on a wall or on the floor or we can work with the six structure of the shape so that the water can walk in a certain way (one of the six paths of the shape).
Athar Lina Groundwater Research Project
Connecting the park to sites of heritage in and around the neighbourhood
A map shows of monuments related to heritage and water on the built environment surrounding the park's area.
Also using this pattern (shape of water) on the benches or a water feature itself. Also, we Flowers of purpose: planting flowers in the garden and kids will be allowed to take can use the figure as a symbol for the site because it reflects both water and the cultural it and give it to their mothers or for any other purpose e.g. visiting cemeteries, heritage of the area Ramadan. The idea is engaging the kids to take care of the garden and the flowers.
Encourage the contribution of local craftspersons to enhance their sense of belonging and ownership of the park.
Kids’ area: using the different elements from the legends of al-Kritliyya house in a different and more creative ways so they can engage the children.

Retail developments along the park at street level will be in harmony with existing shops located across from the park and will not detract from the heritage monuments (al-Ashraf Khalil dome and the Fatima Khatun dome). The park intangibly reclaims the spiritual and historic values of al-Khalifa, while revitalizing the present and future of the neighborhood. It successfully creates a friendly space that provides awareness of environmental issues through its design (wetlands, heritage imagery/wall murals, urban agriculture/garden nursery).
Athar Lina Groundwater Research Project
The park also tangibly reclaims a former ‘dead’ space to fulfill the neighborhood’s recreational and day-to- day need for activities, while purifying the water and air through the introduction of greenery and a water treatment facility. Women and children are provided with a reclaimed public space of their own that is safe, enjoyable, and gives them an opportunity to engage with their community beyond the home. 24

The five-steps of the water treatment process that will be relied on to maximize usage of captured groundwater will also provide the conceptual framework to the park’s overarching design: Capture and Settlement: The Northern park entrance provides a dynamic introduction to the harvesting of groundwater and its conversion into an asset. Filtration: Filtering wetlands continue the cleaning process while providing exposure/learning experiences about how wastewater is converted and cleaned.
Athar Lina Groundwater Research Project
Transition: A designated children’s play area is an outlet for their boundless energy, playful spirit, and playground sounds. This feature serves as an engine transitioning water from waste to asset before it is stored. Collection: Visitors are made aware of an underground water collection tank similar to that found in a sabil through a commemorative footprint at surface level, inscribed in Arabic calligraphy and connected to Islamic fountain-style water channels; Both water and visitors are figuratively and literally collected at this point in the park (where collection and settlement tanks are located underground). Four industrial trickling filters announce the project focus (groundwater treatment), as water is filtered through them into the wetlands. 27

Phase 1: Key points of access and awareness are set up. This will include an entrance from al-Ashraf Street level and an ‘awareness’ courtyard that extends and enhances human use and recreation, and provides space for wetlands (for water purification) and nurseries (for edible plants): Phase 3: Full inclusion of commercial activities in the form of shops, a cafeteria, urban farming and a community market (possible also integrating products from the farming). If applicable, relevant and beneficial investments are added to make the park more fully serviceable, operational and financially independent. As with
Athar Lina Groundwater Research Project
previous phases, commercialization will be pursued according to surveyed observations of community need, with the end result being to fully hand over management and stewardship of the park to the community.
An additional entrance from Zaynhum is added. Spaces are created to facilitate community interaction and to observe user behavior. These spaces include courtyards and benches (to create a sense of place/identity/purpose), and a secondary circulation network that builds on existing spaces from Phase 1 and better amplifies their usefulness. Ultimately, Phase 2 is about creating flexibility through modularity and developing a foundation for all coming phases. This is accomplished by overlaying a ‘6x6’ meter grid so that the design can be adapted over time to suit determined needs. 30

Three main transition spaces act as connection points between al-Ashraf Street level, the elevated park level and finally, the Zaynhum development level. These three transition spaces feature: Two street-level plazas in front of al-Ashraf Khalil dome and the Fatima Khatun dome. These gathering ‘nodes’ will contain water dispensaries (sabil) and small shops that cater to the demands of the community. They will also activate interest in the restored domes. Four elevated park-level spaces that contain exhibitions, facilities for older children, young children and women, and urban agriculture gardening zones. Athar Lina Groundwater Research Project
Primary access to the park and the street-level plazas will be from the Zaynhum access ramp. A groundwater filtering hill will drain into a pond at the upper park-level, and funnel water via gravity to green features such as: the gardening zones, the uphill planted slopes and trees, and the trees at the main entry points. Visitors will be able to view this dynamic process through designated ‘reveal spots’ across the park. Al-Ashraf Khalil dome, the Fatima Khatun dome, and additional monuments in the vicinity will serve as projection walls for cultural activities (eg: Ramadan shows, music, culturally significant films). 33

SMALL PILOT |Ahmed Kuhya Mosque: as a potential case to apply a groundwater reuse system
Ahmed Kuhya Mosque was originally a hall built in 710 AH - 1310 AD. After that, Prince Ahmad Kuhya turned it into a mosque for religious ceremonies. The restoration project started in 2003 in order to restore the mosque to its original architectural style. The foundations were reinforced and the damaged walls and wooden elements of the mosque were repaired. Doors, windows and wooden ceilings were meticulously restored. As well as the implementation of a project to reduce the level of groundwater below the mosque, the floor tiles of the mosque were also changed and the mosque's floor was damp-proofed. Residential buildings to the west and north of the mosque were demolished in order to make room for the dewatering system. An open yard of c. 250 M2 was thus created around the mosque. It is currently abandoned and un-kept.
The mosque is the only structure in the area with a complete dewatering system that decreases the water level by 3.7 meters, pumping 300 cubic meters daily.
Street level next to the mosque is -10 cm, water level in the case of absence of a dewatering system it is -188 cm and with the system it is -455 cm. The ground floor level of the mosque is +225 cm (zero = al-Saliba Street). Dewatering system at Ahmad Kuhya mosque
