Determination of basic household water requirements

The concern for determining the basic or minimum water requirement for a person to maintain good health and proper sanitation comes about in the light of the current state of water resources and the growing scarcity against a rapidly rising population. This paper\u27s contribution is the determination of this basic or minimum water requirement which is necessary to sustain human life and other basic human activities through a record keeping approach and use of an econometric tool. Specifically, the study (1) obtains actual per capita water consumption by activity based on household water usage and (2) determines household and per capita water requirement that cuts across income classes, water sources and cost of water, and location. Results of this study provide a valuable input in water-sector planning (i.e., for water supply infrastructure), allocation of available water supply between domestic and other uses (i.e., industrial and agricultural), and in determining the appropriate water tariff consumption block and structure for domestic consumption as the paper gives an empirical basis for the lifeline or minimum consumption block of about 10 cubic meters per month for a family of 6 members
