Keppel Seghers Engineering Singapore Pte Ltd (Keppel Seghers), a wholly-owned subsidiary of Keppel Infrastructure Holdings Pte Ltd (Keppel Infrastructure), has achieved a substantial handover of the Doha North Sewage Treatment Works (DNSTW) to the client on 10 December 2015.

In addition, as part of the graduated handover process for the Design-Build-Operate project, Keppel Seghers has commenced the operations and maintenance phase of the contract for its liquids stream, solids thickening and dewatering facilities for 10 years.

The DNSTW is a wastewater treatment, water reuse and sludge treatment facility project awarded by Ashghal, the Public Works Authority of Qatar. The facility has the capacity to treat up to an average flow of 245,000m3 of wastewater per day and will be the largest greenfield wastewater treatment, water reuse and sludge treatment facility in Qatar. The high grade reclaimed water from the DNSTW is transferred into Doha's irrigation network.

Dr Ong Tiong Guan, Chief Executive Officer of Keppel Infrastructure, said, "We are happy to have reached a significant milestone for this project that plays a significant role in supporting Qatar's vision for sustainable development. We will continue to work with our client to ensure the smooth operation of the project."

Located northwest of Umm Salal Mohammed, the regional town of Umm Salal municipality, the Doha North facility features bioreactors, granular filters, ultra-filtration, chlorine and ultra-violet disinfection on the liquid stream side; with aerobic digestion, thickening, dewatering, and subsequently, thermal drying of the resultant sludge stream. The plant also features a dual treatment odour control system, comprising chemical scrubbing and carbon polishing, to minimise impact on surrounding communities.

The DNSTW is Keppel Seghers' second landmark project in Qatar. Keppel Seghers also designed, built and handed over the Domestic Solid Waste Management Centre (DSWMC) in October 2011 and entered into the 20-year operations and maintenance phase of the contract. The DSWMC is the first-of-its-kind integrated waste sorting and recycling, waste treatment and green energy generation facility in the Middle East.

Earlier in the month, Keppel Seghers also announced the handover of Bialystok waste-to-energy plant (WTE) in Poland. The WTE plant can process about 120,000 tonnes of waste a year.

The abovementioned handover of the DNSTW is not expected to have a material impact on the net tangible assets and earnings per share of Keppel Corporation Limited for the current financial year.
