Qatar’s Public Works Authority (Ashghal) has invited companies to bid for the contract to build a domestic waste transfer station in the Al-Khor area of Doha.

Contractors have until 27 August to submit prices for the contract to build the Al-Khor domestic solid waste management facility.

The work will involve building and providing all of the equipment and machinery for the waste management facility. In addition to the waste transfer station, the facilities will include a loading centre, administration building, staff accommodation building, storage building and an internal roads network. The contract will also involve building car parking and carrying out soft and hard landscaping.

The project is the latest of a number of wastewater projects that Doha is pressing ahead with as it seeks to expand the country’s utilities infrastructure.

In May, Ashghal received prequalification entries for the five main packages on the estimated QR10bn ($2.7bn) Inner Doha Resewerage Implementation Strategy (Idris).

The Idris project involves building a series of deep tunnels that will serve the Doha South catchment area over the next 50 years. The scheme will eliminate the need for pumping stations in the Doha South area.

The project also involves 76 kilometres of lateral interceptor sewers, 33km of trunk sewer, a terminal pump station, a New Doha South sewage treatment plant, 92km of treated sewage effluent return facilities and the decommissioning of 37 existing pump stations.

Once treated, the effluent will then be transported to any end-user via a TSE return system. Once complete, up to 500,000 cubic metres a day (cm/d) of high-quality TSE will be produced that can be used for irrigation and other purposes.

Ashghal appointed the US’ CH2M Hill in late 2011 to manage the scheme. The firm has worked on the concept design and preliminary design, and will also manage the design and construction consultants
