KSA completes largest sewage treatment plant
National Water Company to start operations at sixth plant in Riyadh.
The National Water Company (NWC) has completed the construction of the largest sewage treatment plant in the Kingdom.
The plant in Riyadh will start operations at the end of November, with NWC running the plant on a trial basis to ensure its effectiveness, according to Arab News.
The tertiary treatment of sewage is estimated at more than SAR 400mn ($106.6mn), with a capacity of 400,000 cubic meters per day (m3/d), rising at peak times to 640,000 m3 daily.
The plant, the sixth in the Saudi capital, will receive sewage from all Riyadh districts and treat it using high technical standards.
Earlier, NWC had announced the completion of the first phase of the transmission lines of 25 km to deliver sewage to the station with amounts of up to 150,000 cubic meters per day.
NWC is currently working on the implementation of the second phase of the transmission lines estimated at more than SAR 700mn, with a total length 38 km to transfer more than 250,000 cubic meters of waste water per day to the station to be processed.
So far, NWC has completed 60% of these lines. The company said in a statement that the state-of-the-art station is part of the ecofriendly solutions for the treatment of waste water and will reduce the total overall age-design costs of the plant.
The plant will also reduce the content of chemical materials in the treated water.
