Sewage works

25 April 2008

Construction of the Doha South sewage treatment works involves tripling the capacity of the network in just six months to meet the demands of 390000 people. According to Hyder Consulting’s project manager, Martin J. Rendell, “Working in the desert hasn’t been difficult, it’s the fact that things are still running and we only have short shut down periods in the middle of the night. It’s been very intense.”

The new facility involves bringing two sequencing batch reactor (SBR) sludge treatment works on-line. “The SPR works in series and replaces the old primary, secondary and tertiary filtration system. There are eight tanks in all on a continuous cycle and it feeds into the tertiary filter. However, we’ll go beyond this with UV filtration.”
