On the other hand, installing rainwater harvesting systems is verified by a number of studies to provide local communities a sustainable water source, accompanied by other various benefits, including protection from flood and control of water runoff, even in poor regions. Rainwater harvesting systems that do not require major construction or periodic maintenance by a professional from outside the community are more friendly to the environment and more likely to benefit the local people for a longer period of time. Thus, rainwater harvesting systems that could be installed and maintained by local people have bigger chances to be accepted and used by more people.

Desert. Increase in rainwater harvesting efforts across the nation have revived ancient water harvesting systems in
Rajasthan, such as the chauka system from the Jaipur district. Other large cities like Pune, Mumbai and Bangalore all have varying rules for mandatory rainwater harvesting, especially in new buildings. In 2002, the Municipal Corporation of Greater Mumbai required all new buildings over 1000 square meters to have rainwater harvesting infrastructure. The law was expanded in 2007 to 300 square meters. The goal was to ensure buildings had enough water to last them through non-monsoon seasons. The process included a catchment system, an initial flush, and extensive filtering. As of 2021, the

enable groundwater levels to be sustained. Rainwater harvesting increases the availability of water during dry seasons by increasing the levels of dried borewells and wells. Surface water supply is readily available for various purposes thus reducing dependence on underground water. It improves the quality of ground by diluting salinity. It does not cause pollution and is environmentally friendly. It is cost-effective and easily affordable. It also helps in the availability of potable water, as rainwater is substantially free of salinity and other salts. Applications of rainwater harvesting in

Provincial and municipal legislation is in place for regulating the rights and uses for captured rainwater. Substantial reform to Canadian law since the mid-2000s has increased the use of this technology in agricultural, industrial, and residential use, but ambiguity remains amongst legislation in many provinces. Bylaws and local municipal codes often regulate rainwater harvesting.
