Builders in rural areas have for many years constructed water supply systems, such as roof gutters and water tanks for catchment of rainwater, handdug wells, subsurface dams, weirs, sand dams, ponds and small earth dams. The clients have either been individuals, non-governmental organizations (NGOs), government ministries, or donors such as Danida, Sida and UNDP. Many of these water projects function well and supply water, and, according to the waterusers, do so without problems. However, some water projects do not function very well, while others are complete failures, and the reasons are a mixture of insufficient knowledge about surveying, design drawings, estimating bills of quantities, and costing accurately, as well as inadequate training of technicians and contractors, and improper operation and maintenance by the water users.
This handbook, Water Supply by Rural Builders, is the 8th in a series of handbooks that gives guidelines on how to carry out simple, yet adequate, surveys, designs and construction of basic water projects.
