The contract covers the design and supply of an additional eight of ITT's Sanitaire sequence batch reactors (SBRs), which will increase the wastewater treatment capacity of the Doha South plant by 92 million litres per day. Also included in the Phase II extension is the addition of an ultra-filtration plant designed and supplied by ITT, which will produce a high standard of treated effluent suitable for reuse in irrigation.
 

John Williamson, president of ITT's Water & Wastewater group said: “We are proud to build on the success of the first phase of the Doha South project and to continue our partnership with Larsen & Tourbro and ASHGHAL, Qatar's public works authority. Ultimately, this project is about supporting the growth and development of the Doha region and we are honoured to have a role in ensuring a clean water supply for the Qatari people.”
 

With Phase I operational and the completion of Phase II, the plant will have a total capacity to treat 187 million litres of wastewater per day. This will be the largest wastewater treatment facility using SBRs combined with ultra-filtration in the Gulf Cooperation Council (GCC) region.
 

The Phase II extension is expected to be operational by 2012.
