Community water-supply schemes are generally designed for water consumption in the approximate range of 15 to 60 litres per person per day. Allowance has also to be made for water use by livestock, for future growth in population and demand, and for losses of water by leakage etc. from the system.
It is important to check that the discharge of the source is enough, throughout the year, to meet the community's requirements. This requires measuring or estimating the dry season flow, when least water will be available.
