Project:

Dar Es Salaam Water Supply Distribution Network (Part 1)

Location:

Bagamoyo Town, Tanzania

Client:

Dar-es-salaam Water Supply and Sanitation Authority (DAWASA)

Business Sectors:

• Drinking Water Network

Services (Technical Disciplines):

• Construction Supervision
• Capacity Building

Project Objectives/Outcomes:

Dar es Salaam accounts for 40 percent of the urban population of Tanzania and is expected to continue to absorb the bulk of new urban residents. By 2030 it is expected to have over 10 million inhabitants, many of whom will reside in peri-urban areas that are currently underserved. Given its role as the engine of the economy, and the locus of key industries, commerce, the port, the rail and road transport services, it will continue to draw more resources, including water. Keeping up with the demand for provision of sustainable infrastructure, including water supply and sanitation (WSS), is therefore a critical challenge for the city.

Through various investments on the supply side, the water production capacity for Dar es Salaam is expected to double, and this project aimed at distributing this extra water by enabling expansion of Water Supply Distribution in Unserved Priority Areas. Part one (packages 2B and 2F) (Tegeta-Mpiji and Mpiji-Bagamoyo) was a key priority for expansion given the historically low levels of service. The project scope provided for an additional 1,260km of pipes, 42 kiosks, and 214 stand posts and benefit for 453,000 people.

The project included the supervision of supply and installation of Secondary and Tertiary Distribution Network and Installation of Domestic Meters from University Reservoirs to Bagamoyo Town. The Project included the construction of 1,500km of the following: 200mm to 75mm Diameter Tertiary Watermains:  500mm to 250mm Diameter Primary Watermains; over 50 No. PRV’s, District Meters etc.; 3 No. 5,000 m³ RC Reservoirs and 3 No. Pumping Stations.
