Saudi Arabia’s National Water Company (NWC) aims to increase its treated sewage effluent (TSE) production to 6.3 million cubic metres a day by 2032, almost three times the level recorded in 2012, the annual NWC Symposium in Jeddah was told on 4 December.

“We can see huge demand for TSE,” said NWC executive director and head of TSE, Montazar Muhalhal. “The three fastest-growing segments are government, commercial and industrial.”

The NWC has launched a TSE commercialisation programme and has long-term contracts to sell TSE with a total value of more than SR5.4bn ($2bn) the symposium was told.
