Status of RWCS development and progress of IRCSA.
The development of rainwater catchment systems (RWCS) has been gaining great momentum worldwide in recent decades. This is partly due to the United Nations General Assembly’s proclamation of 1981-1990 as the International Drinking Water Supply and Sanitation Decade and partly due to the series of international conferences on rainwater catchment systems that began in June 1982. To date, eight conferences have been held at about two-year intervals in different cities of the world to promote RWCS development. A brief description of the Thailand Jar Project, an example of a national project that aimed to provide a safe and adequate drinking water supply for the country’s rural residents, is included in this paper. Highlights of the progress in RWCS development made by the International Rainwater Catchment Systems Association, which was formed at the fourth conference in August 1989, are also included.
