NATURAL SPRING-2 NEAR UNDER CONSTRUCTION CABLE TUNNEL

This is natural spring is located on right side of the under construction Cables Outlet Tunnel and its water from it is flowing out of the right front wing stabilized wall of the Cable Outlet Tunnel at about 6 feet height above ground level, refer Plate-VI and VII. Water of the spring is crystal clear and its Chemical Test Report at Annexure-III shows that it is chemically fit w.r.t. WHO Limits for Drinking Water. Discharge of this spring was physically measured during site visit on 21-02-2009 and found to be about .0105 cusecs or 56,700 gallons per day (24 hours). Discharge behaviour of this spring round the wet and dry seasons is, however, not known which should biweekly be monitored by the ARE or his Inspector at C3 to find out its maximum and minimum flow for its final selection as a vitally suitable water source for C3 Colony supplemented by water from sprin-1 discussed above earlier. In case this spring is to be adopted as main water source for C3 Colony care shall be taken while blasting for excavating Cable Outlet Tunnel in its close vicinity to avoid its disturbance, changing its course or closure which happens in case of some natural springs in hilly terrain. For using this spring as main source of water supply to C3 Colony training and collection works, gravity feed line to a low level sump , pump house with pumps and rising mains to the storage tank on high hill shall be planned, designed and constructed to harness this vital water source.
