Bids invited for water supply project in Mozambique

August 25th, 2023

Mozambique’s Water and Sanitation Infrastructure Administration is inviting bids without prequalification for the construction, rehabilitation and expansion of Nametil and Malema City Water Supply Works.

The Nametil water supply system will consist of the following elements:

  • abstraction works (pump replacement)
  • Water treatment plant (WTP)
  • bulk conveyance
  • storage (ground and elevated reservoir)
  • distribution network

The water will be abstracted from the Meluli River at the existing dam and pumped to the existing water treatment plant. Conventional treatment usually involves coagulation, flocculation, sedimentation, sand filter with gravity action, and disinfection. After treatment, the treated water will be pumped via uPVC DN400 to the distribution centre to be located to the north of the village about 4km from the WTP and will consist of a 2,000m3 ground reservoir and a 300m3 elevated tank. 

The Malema water supply system consists of the following elements:

  • rehabilitation of the existing water abstraction on the Mutivasse River complemented by an additional raw water source (Malema River)
  • construction of a new WTP
  • reinforcement of the water transmission capacity
  • new reservoirs and expansion of the distribution network.

Specifically, the project involves increasing the intake capacity of the existing raw water catchment (increasing the height of the existing weir); rehabilitation/installation of valves and operation of the existing raw water transmission; construction of a new water pipeline parallel to the existing one connecting the old intake to the new WTP; construction of a WTP (currently non-existent); construction of new storage reservoirs (to be used also as service reservoirs); and expansion/optimisation of the existing distribution network through reinforcement/replacement of existing main trunks, including optimisation through the establishment/creation of metering/supply areas.

The World Bank is funding the project. The work is being let as one lot.

Interested firms can inspect the bidding document and obtain further information from the address below from 08h00 to 15h30, Monday to Friday.

Bids must be physically delivered by 13h00 on 5 October 2023. Electronic submissions will not be accepted.
