The project is meant to benefit residents of three wards in Mitega, Miteja, Tingi and Migumbi in Kilwa North Constituency.
Minister for Water and Irrigation Gerson Lwenge is expected to lay the foundation stone to kick-start the long-awaited water project.
Briefing journalists over the weekend, Kilwa District Engineer Magai Kakuru said the project was being implemented by a Tanzanian construction firm, Patty Interplan Limited, which started the project in November 2015 and will be ready for use April, this year.
Eng Kakuru said four water tanks with capacities ranging from 500,000 litres to 150,000 litres, 100,000 litres and 50,000 litres have been constructed in the project area.
He said that for years people in the area have been relying on salty water and other unhygienic sources for the precious liquid.
He said that people in such areas were used to buying water for up to 1,000/- per a 20-litre jerry can.
Villages which are to benefit from the water project include Njinjo, Nanjilinji, Ngea, Kandawale, Mtandi and Hanga in the district.
Eng Kakuru said that in order to ensure that the project became sustainable, water user communities have been formed in every village.
