Minet el Bassal district was one of the famous Alexandrian Industrial districts. It is located in the neighborhood of West Alexandria, near the end of the Mahmoudiya Canal in front of the Western Harbor gate at Alexandria Port.The district also hosts an old market well known to the Alexandrians’ for selling used goods called “Souk El-Gomaa”, in English; Friday market. Nowadays, these street vendors occupied the area all week long, and became a threat to local workers.

OWNER These industrial heritage buildings are owned by the Egyptian company for pressing cotton, it is a subsidiary of the Egyptian joint stock, which is owned by the Holding Company for Spinning, Weaving and Clothing.

PAST SITUATION OF MAHMOUDIA CANAL

OVERVIEW

the fluctuation caused by poor qaulity and quntity of water coming from the Rosetta, while wastewater problems in Alexandria are mainly that the waste water is disposed in Mediterranean Sea and the Mariout Lake.Pollution and waste water comes from Edko drain in Beheira governorate on north-east of Alexandria.

The Analysis of the Canal in Alexandria

THE NILE AND THE CANAL ANALYSIS Al-Mahmoudiya Canal acts as a connecter between Rosetta Branch of the Nile and the Mediterranean Sea in Alexandria. the 77.170 km canal is fed with fresh water from El-Atf pump station on Rosetta branch, and through Al-Khandaq Eastren canal.

The main problem facing the canal is

WASTEWATER TREATMENT IN THE CANAL

School

Land not in use/ Derelict

Bank Building

Lost Space

The canal passes through different cities until it reaches Alexandria. It is neglected and used as wastewater and garbage collector, even though it has the potential of being revitalized through creating new system of wastewater treatment which will lead to the revival of the surrounding areas including Minet el Bassal district in Alexandria.

Context Analysis map site scale analysis of waste water water supply, water treatment, waste water drainage The illustration shows important districts and the usage of buildings around the canal, to find suitable places for intervention. It shows that most of the surrounding areas are either derelect buildings or lost spaces used as garbage dumps.

When the water quality index was tested in Al-Mahmoudiya Canal, the results showed that it ranged from 38.99 ( poor water quality) to 55.39 (marginal water quality). The lowest value of water was in Winter and the highest was in Autumn.

The primary and secondary water treatment systems were not efficient enough to remove the polutants from the canal which indicates the incapability of the convential centralized system to treat wastewater.

Due to the excessive use of fertilizers by farmers in agriculutral activities, there is „migration of pollutants“ within the canal.

Wastewater Cycle

The industrial demand for water in Egypt in 2000 was 3.6 BCM/ Year* and in 2017 will be 5.5 BCM/Year.

Wastewater in Egypt is 3.5 BCM/ Year , only 1.6 BCM/Year is treeated. *BCM/Year Billion cubic meters/year

1868 1902 1905 1914 1917 1921 1952 1887 1810: Minet El-Bassal district was built o form a trade center for all Egyptian products exported to Eur pean countries. 1850: A freight railway was built in the 1850s to serve the western port and Mahmoudiya Canal already built, triggered extensive industrial development in this area. The city controlled virtually the whole of the cotton industry of Egypt. 1870, Alexandria was the fourth leading Mediterranean port after Istanbul and Marseilles. 1952 Many of these buildings were out of work, focusing on the local manufacturing of cotton in the Delta, beside agriculture land. Many of them are on their way to be demolished and the sites will be clear for “new enterprises”.

Small-scaled interventions must be done that can be considered a propotype replicated around the canal. There are many surrounding derelect buildings that can be adaptively reused as a wastewater and rainwater decentralized treatment stations.

In order to reach a sustainable solution for the issue of the canal, the centralized system of water treatment must be broken down and assisted by decentralized ones for lower presure on the central station, minimal impact on environemnt and less cost; the cost of decentralized system Small-scaled interventions must be done that can be considered a propotype replicated around the canal. There are many surrounding derelect buildings that can be adaptively reused as a wastewater and rainwater decentralized treatment stations of Living machine is 1/4 less than the cost of normal municipal wastewater treatement station.

The living machine with its „Reactors“ would be used to make this system function efficiently. the designated area of 34,000 sqm in Minet el Bassal with its multiple layers of the living machine can purify about4,650,000 litres/day which would cover the needs of the canal strip nearby and the neighborhood.* the system will be connected to the sewage system and then exract the wastewater through sewer mining and then proceeded in the living machine to purify the water before it is dumped in the canal. The canal will be also connected to the system to filter and purify its water. this living machine would also work as a park for the locals and the tourists which would bring more attraction to the area and make the
