Water from wells
There are a number of wells in use, the majority of which, however, supply water
used only for industrial purposes. The water from three wells is used for drinking
purposes, or for the preparation of food. Reports of the analyses of water from these
wells are received regularly, and have been satisfactory for the year under review.
The well in Clapham, Rectory Grove, formerly in the old Metropolitan Borough of
Wandsworth, is used if and when required to augment the Metropolitan Water Board
supply. This well is 400 feet deep supplying 15,000 gallons per hour, and was
originally installed in 1927.
