Smout, I., Shaw, R. (1991) Intakes from rivers
A typical small water supply system requires less than about 200,000 litres per day, which is well within the capacity of small streams and alternative water sources, other than rivers. Indeed a river is not the ideal source of domestic water in many situations and an intake would normally be constructed only if there is no satisfactory alternative source such as groundwater (handpump), rainwater (catchment […]

Skinner, B., Shaw, R. (1999) Protecting springs - an alternative to spring boxes
Many publications describe the protection of springs from contamination using spring boxes. The construction of such a structure takes time and money, and in many cases it may not be really necessary. A spring box can be useful as: -A sedimentation chamber where particles of sand carried in the spring water can settle out. -A storage chamber, which is useful for springs where the peak rate of demand […]
