 Rainwater harvesting
 Rainwater
harvesting for domestic use and as drinking water source is becoming
increasingly popular and necessary as the availability of good quality water
declines. Rainwater is acknowledged as a sustainable source of water that has
less impact on the environment. Households and communities have augmented or
substituted their household supplies with rainwater for reasons of scarcity,
salinity, quality of service and for risk substitution. While rainwater may
not always provide a full-year round of supply, it enhances water security in
the house and generally provides a good quality water. Rainwater may be the
sole source of water in countries like the Maldives
and upland Sri Lanka, provide
an alternative to arsenic-laden ground water in Bangladesh
and augment inadequate urban supplies from Chennai to Kathmandu and scattered
households in the mountain ridges in Bhutan. Its use is nowadays
promoted by NGOs and authorities alike for numerous domestic applications
like drinking, cooking, bathing, laundry, toilet flushing and for gardening
purposes. Infiltration to sustain local aquifers is suggested as well.
