Objective:
Rural areas of Sub-Saharan Africa face the most acute water supply challenges in the world. Nigeria, the most populous African country, has considerable populations without basic access to safe drinking water, with more than 50% of the country lacking coverage. The village of Adu Achi, Oji River Local Government Area, Enugu State currently seeks to develop a gravity-fed, distribution system employing groundwater from an aquifer in the Mamu formation. The village and surrounding areas consist of approximately 5,000 people currently relying upon contaminated surface water 3 km from households, on average. The lengthy dry season from November to March, the inconsistent quality of nearby surface water, and the traditional worship of the local water bodies have led groundwater to be selected as the source of supply. The main barriers to developing sustainable water provisions for the region are the intermittent power supply, the depth of the aquifer (more than 600 feet), informal government structures within the community, and economic support.
Summary/Accomplishments (Outputs/Outcomes):
Remote collaboration of partners, as well as interaction during a 3-week site visit to Nigeria in the winter of 2008 led to the design of a comprehensive water program, as well as implementation of initial infrastructure. Two subsequent implementation trips have taken place in May through November 25, 2008 and June 2009 to the present, with one student remaining onsite for long-term stints to oversee continuing work. Regional borehole drillers were found, and a productive borehole well was drilled and made accessible with a 27 m3/day capacity submerged pump. Power supply options including wind, solar, biofuels, and diesel generators were investigated and compared, leading to the choice of a 40kVa diesel generator set as the most viable technology. Ferrocement reservoirs were designed and constructed to meet a daily demand of 200,000 liters. A PVC pipeline for water distribution was designed and currently is under construction throughout the community. Tapstands for public access were designed and several have been constructed. Two chlorination scenarios were researched and designed, leading to an intermittent shock chlorination plan to manage biofilm growth and any other contamination risks. Cassava basins have been designed and are planned in conjunction with the women's center of a partner organization. A Water Project Maintenance Committee was formed to oversee the operations and maintenance of the project over the long term, including technical, social, and financial aspects.
Conclusions:
In order to ensure adequate, consistent, and clean water supply to a large, economically challenged population of approximately 5,000, an innovative and comprehensive program must include: (1) appropriate technical design and implementation of infrastructure elements, (2) community oversight of how this infrastructure should be built and subsequent management of the system, (3) concurrent education programs to reduce existing gaps in technical understanding and basic sanitation practices, and (4) enhanced health and quality of life benefits. Implementation and evaluation of this program will provide water for the Adu Achi community, currently lacking access to an improved water source, while also serving as a basis for other communities, especially similar Nigerian localities, to emulate and adopt similar strategies to develop and manage community water supplies. Work on this project has demonstrated that long-term facilitation of community members and technical oversight are the major necessity for continued expansion of locally managed centralized water supplies.
