Hydraulic Performance and Rehabilitation Strategies
- 174 Downloads
Over the past twenty years a major financial effort has been made to improve the water supply in Portugal. A significant evolution can be observed, with 77% of the population currently connected to public systems and a target of 95% by the year 2000. Supplying a high percentage of the population is however not sufficient by itself. The quality of the service provided to the users is a fundamental issue, particularly where continuity of supply, water quality and reliability are concerned. Recent surveys based on simplified criteria indicate that 40% of the population supplied are thought to enjoy a good service, 54% an adequate service, and 6% a poor service.
