The recommendations and principles from Agenda 21 cover water resources management in general, . including availability of water, demand regulation, supply and tariffs, whereas water pollution control should be considered as a subset of water resources management. Water resources management entails two closely related elements, that is the maintenance and development of adequate quantities of water of adequate quality (see Case Study V, South Africa). Thus, water resources management cannot be conducted properly without paying due attention to water quality aspects. It is very important to take note of this integrated relationship between water resources management and water pollution control.
