WASCO have been actively involved in watershed development programmes since from 1995. Organization started its work from western part of the Rajasthan which is almost dry & desert. Rainfall in this area is irregular & erratic, so team of WASCO thought that Organization should do work mainly on rain water harvesting i.e. on watershed approach. Since from 1995 WASCO executed ten micro watershed projects under DDP & EAS in the catchment area of Apeshwar river Ramsin in Jaswantpura block of Jalore Distt with active participation of watershed committees/ watershed association & village community. The role of WASCO (PIA) was like as catalyst for strengthening of watershed committees.
