of implementation, time of implementation, designer<br />
details and the type of the RWH structures. Only<br />
53% of the respondents are implemented during the<br />
year 2003, rest of them implemented before 2003.<br />
They have spent Rs. 2000 to 4000 on an average.<br />

Most of the respondents reported that they had<br />
implemented RWH using the open well through<br />
filter while few had resorted to percolation pit. RWH<br />
system like recharge well, recharge cum bore pit<br />
were not implemented. RWH through open well is<br />
common because the top soil is clayey in nature<br />
and if any other structure would be effective only if<br />
implemented at high depth.<br />
