Qatar plans to invest $3 billion in improving sewerage infrastructure conditions in the capital. The authorities – and their new advisors – have yet to decide whether to include a private finance element.

The Public Works Authority in Qatar (Ashghal) has appointed CH2M Hill to oversee a QAR10-12 billion ($2.7- 3.3 billion)sewerage project that will overhaul wastewater services in developing areas of Doha over the next seven years.

 
The Inner Doha Re-sewerage Integrated System (IDRIS) project, due for completion by 2019, will deal with an area of the capital which is set to be heavily developed, with new higher-density buildings being built as part of the country’s expected infrastructure boom over the next decade.
 
While many details of the project still remain undecided, it will include the construction of a major wastewater treatment plant to the south of Doha, as well as a deep-trunk sewer tunnel, pumping stations, ocean outfall and sewage forwarding and TSE return mains (see Reuse Tracker p53). The majority of the project will be paid for through direct public funding. A private finance element for the treatment plant has not been formally ruled out, but no decision has yet been made.
 
The capacity of the plant has not yet been decided, with a source saying only that it would be in the region of 80,000- 400,000m3/d. Treated water produced at the plant is likely to be reused, but the exact level of treatment and the choice of customers for the treated water will depend on consultation with the Qatari master plan for wastewater treatment and reuse.
 
CH2M Hill has been awarded the QAR225 million ($62 million) contract to act as programme manager for the IDRIS scheme, and will be working on a feasibility study, concept design management and the oversight of procurement as well as post-contract asset management.
 
Amer Battikhi, the business development director for the MENA region at CH2M’s water business group, said the company had been awarded the contract based on its success in other deep-tunnel sewerage projects in places like Abu Dhabi and Singapore.
 
“We have been present in Qatar for a while, but this is our biggest contract yet with Ashghal, and it’s key to us because of the type of work,” he told GWI. “Sewerage tunnels and integrated systems is something that we have done all over the world, and this is a continuation of what we have accomplished.”
 
CH2M will be working closely with MWH, the advisor on Qatar’s national wastewater master plan, when it comes to carrying out the project, and particularly when it comes to thrashing out details of the reuse element of the scheme, Battikhi added.
