|‘providing water to sub-Saharan towns and villages’
Sokoto State, nigeria
- Turnkey contract for water supply infrastructure for communities within Sokoto State.
- Reliable, safe, water to W.H.O. Standards provided to over 160,000 people.
- Biwater Tower treatment plants allowed fast track construction and minimised difficulties in transportation to the most northerly part of Nigeria.
Biwater Tower Site
As part of the Federal Government of Nigeria's commitment to improving the quality of life of its people by developing the areas bordering the Sahara Desert, the Sokoto State Government and Biwater worked together to provide a long term solution to the problems associated with a constant lack of water.
The first phase of this solution was the Sokoto State Rural Water Supply Project providing five turnkey water supply schemes drawing water from deep boreholes and three pipeline schemes extending the existing supply in Sokoto town to the many smaller communities on the outskirts of the town.
The five borehole schemes all utilised Biwater Towers as the most compact and cost effective means of treating and storing potable water. The extension to the existing supply included major pipelines in excess of 56km, booster pumping stations, surge suppression and storage tanks and a total of 32km of distribution pipework was installed.
The existing water supplies were shallow hand dug wells and non perennial rivers which were insufficient for the current population and would certainly not cater for the predicted population growth of forthcoming years.
||Sokoto State is located above sedimentary rocks containing very high volumes of water but this water is hundreds of feet below ground.
Biwater has the skills, the knowledge and the equipment to drill to these depths and was able to provide the means to raise this water, treat it to World Health Organisation standards and bring it to the people.
Sokoto State is the most northerly region of Nigeria bordering the Sahara Desert and with little local resources or materials for construction, the Biwater Tower provided an ideal solution to the treatment of this groundwater with inclusion of adequate storage of the treated water all in a single unit.
Each tower was prefabricated in sections to allow easy transportation and erection at site requiring only the prefabricated foundation ring to be cast into a simple concrete base and as little maintenance of the tower is required, the continued treatment of water can be assured for many years.
