Integrated water resources management and the provision of water supply and sanitation in small urban centres 1

All urban centres need a regular supply of good quality raw water for the provision of water supply and the means to dispose of waste-water. In recent years, there has been a growing recognition of the need to fit provision for water supply and sanitation within a framework that considers the needs and demands of all water-using sectors and ecological processes. Doing so is usually termed integrated water resources management (IWRM) and this is usually done within a water drainage basin unit.
