In June 2020 construction work commenced on the Dar Es Salaam Water Distribution Networks Project, Part 1. The project involves the construction of 1,500km of water transmission and distribution pipelines, ranging in diameter from 500mm to 75mm, 3 No. Reservoirs and 2 No. Pumping Stations. The project site is located in the northern environs of Dar Es Salaam and extends for 60km northwards along the coastal belt to the town of Bagamoyo.  The project will serve a population of over half a million people.

The source of supply is the 1,800mm diameter Transmission Main from the Lower Ruvu Water Treatment Plant to the University Reservoir Complex in Dar Es Salaam.

​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 periurban areas that are currently under-served. Given its role as the engine of the economy, and the focus of key industries, commerce, the port, the rail and road transport services, it will continue to draw on more resources, including water supply. Keeping up with the demand for provision of sustainable infrastructure, including water supply and sanitation (WSS), is therefore a critical challenge for the city.

Nicholas O’Dwyer and Co. Ltd. are the supervising consultant for the Construction Stage. The construction period is two years.
