Abstract: In many parts of the world, the amount of water being consumed has exceeded the annual level of renewal, thus creating a non sustainable situation. As per the international norms, if per-capita water availability is less than 1700m3 per year then the country is categorized as water stressed and if it is less than 1000m3 per capita per year then the country is classified as water scarce. In India per capita surface water availability in the years 1991 and 200 I were 2309 and 1902m3 and these are projected to reduce to 1401 and I [91m3 by the years 2025 and 2050 respectively. Hence, there is a need for proper planning, development and management of the greatest assets of the country, viz. water and land resources for raising the standards of living of the millions of people, particularly in the rural areas. The enormity of the water crisis and the need for water conservation can hardly be over emphasised. Government agencies across the globe are introducing policies to promote increased usc of directly captured rainwater, as an supplementary source of drinking water. The Government of Kerala has introduced legislation making roof top rainwater harvesting mandatory in all newly constructed buildings in the state. The quality of harvested rainwater depends upon many factors such as air quality, system design and maintenance, materials used, rainfall intensity, length of time between rainfall events, social context as well as water handling. In this context, the studies on quality of rainwater are of relevance. The present study focused on the quality of rainwater at various land use locations and its variations on interaction with various domestic rainwater harvesting systems.Sampling sites were selected based upon the [and use pattern of the locations and were classified as rural, urban, industrial and sub urban.
