Design-build of the 6,000 m³/day STLV desalination plant for southern Gaza

MACC designed and built the 6,000 m³/day Short Term Low Volume seawater desalination plant in Deir Al Balah for UNICEF with European Union funding, the first phase of the Southern Gaza Desalination Plant.

MACC designed and built the Short Term Low Volume (STLV) seawater desalination plant in Deir Al Balah, the first phase of the Southern Gaza Desalination Plant, for UNICEF with European Union funding as part of a Palestinian Water Authority programme. The design-build contract ran from December 2014 to September 2017 and covered design, supply, installation, testing and commissioning.

The plant produces 6,000 m³/day by single-pass seawater reverse osmosis with ERI energy-recovery devices. Four beach wells (three duty, one standby) feed sand filters and a 400 m³ intermediate tank, followed by cartridge filters and the RO trains; the permeate is disinfected and pH-adjusted. The works include the RO main building, electrical and chemical rooms, the brine outfall with onshore and offshore lines, grid connection with standby generators and SCADA.

When it opened in 2017 it was the largest seawater desalination plant in the Gaza Strip. Its water is blended with groundwater for supply in the southern governorates, and MACC later expanded the plant to 20,000 m³/day.
