[방글라데시] 모트맥도널드, 다카에 식수 처리시설 설계

공학 컨설턴트 회사인 모트맥도널드(Mott MacDonald)가 다카 상하수도 관리국(DWASA)의 다카 환경 지속 가능한 상수도 프로젝트(DESWSP)의 관리, 설계 및 감독 컨설턴트로 임명됐다.

그 일환으로 모트맥도널드(Mott MacDonald)는 약 24km의 원수(原水) 파이프라인과 수처리시설의 새로운 강물 유입 설계 검토 및 건설감독을 담당하게 된다.

이는 50만m3/day를 제공하며 향후 500만m3/day의 추가공급이 가능해진다.

또한, 이 컨설팅은 상세 설계를 제공하고 처리 된 물을 이송하기 위한 두 번째 파이프라인(15km)의 조달 및 감독을 지원할 뿐만 아니라 다카 거리 아래에 직경 1.8m의 새로운 파이프 네트워크 21km를 배치하여 물을 보급한다.

다카 환경 지속 가능한 상수도 프로젝트는 2020년 완료될 것으로 예상된다.

DHAKA DRINKING WATER TREATMENT PLANT TO BE DESIGNED BY MOTT MACDONALD

Engineering consultancy Mott MacDonald has been appointed as the management, design and supervision consultant by Bangladesh’s Dhaka Water Supply and Sewerage Authority (DWASA) for the Dhaka environmentally sustainable water supply project (DESWSP).

As part of the contract, Mott MacDonald will be responsible for design review and construction supervision of a new river water intake, an approximately 24km raw water pipeline and a water treatment plant.

This will be capable of delivering 500,000 m3/day, with a future provision of an additional 500,000 m3/day.

The consultancy will also provide the detailed design, assist with procurement and supervise construction of a second 15km transmission pipeline to transfer treated water, as well as a 21km new pipe network of 1.8m diameter under Dhaka’s streets to distribute it.

Dhaka has an estimated population of over 15 million, which is forecast to grow to approximately 29 million by 2035.

Groundwater sources currently form 100% of water supply to households in most services zones, which has resulted in the water table decreasing by two-three metres annually.

This means up to 60 deep tube wells become inoperable each year, depriving the population of reliable water supply. The city’s existing source of surface water, the Sitalakhya River, is also becoming increasingly polluted to the point that treatment is sometimes not possible.

Once complete, the DESWSP will provide a 24-hour, reliable and sustainable supply of drinking water to three million people in the city by developing a new surface water source to strengthen existing surface water sources and replace failing groundwater supplies.

Nigel Osmaston, Mott MacDonald’s team leader, said: “This appointment builds on our work of the last three years, which has included reviewing and finalising feasibility studies and assisting DWASA and the Asian Development Bank to develop, trial and improve an innovative multi-lateral design, build and operate contractor procurement process.”

The DESWSP is expected to be completed in 2020.
