Central Gaza Wastewater Treatment Plant, known as Sheikh Ajleen WWTP, is to be upgraded for a capacity of 90,000 m³/day. The works are implemented at the site of the existing Wastewater Treatment Plant. New process units will be added in parallel with the existing units so that the existing treatment plant can continue to be operated while the new works are under construction. On completion, the flows will be diverted to the new works and the existing process units will be partly taken out of operation. By the same mechanism, a new pump station will be constructed at the same site, because of the overloaded flow that the existing pump station in Gaza City encounters. On completion, the flows will be diverted to the new pump station and the existing pump station will be partly taken out of operation.

Due to the embargo Israel is imposing on the Gaza Strip, this upgrading project was divided into two contracts: Contract 1 is for material supply, and Contract 2 is devoted to the construction stage of new process units. Owing to its high qualifications and experience, MACC was awarded both contracts.

The works of Contract 2: Construction works shall include civil and building construction, testing and commissioning of the facilities, including installation, erection and site testing of equipment and materials supplied under Contract 1.
