WATER.
The sources of public water supply remain the same as last
year, by Statutory Undertakers, the major part of the district
being supplied by the Oolne Valley Water Company. A small
area in the southern part of the Borough comprising the
Council's Manor Farm Housing Estate is supplied by the
Rickmansworth & Uxbridge Water Company, while four
cottages belonging to the London, Midland & Scottish Railway
Company take their supply from the railway company's private
main. The water from these sources is a continuous supply,
and during the year was satisfactory in quality and quantity.
The Colne Valley Water supply is softened and chlorinated by
the chloramine process, the purity of supply being under the
supervision of a resident chemical and bacteriological staff,
which carries out examinations in modern laboratories situated
at the Company’s works.
The supply of the Rickmansworth and Uxbridge Water
Company is also chlorinated by the chloramine process, and the
company states that samples of water are taken from each of
their pumping stations for analysis regularly each month.
Samples of drinking water were taken by this Department
and submitted to the Clinical Research Association for
examination during the year. Appended is a table showing
typical results of these chemical and bacteriological examinations.
There are no private wells in the Borough used for the
supply of water for domestic purposes. There are, however,
5 private wells in the district known to the Department which
supply water for factory purposes, 2 factories have 2 wells
each and 1 factory has 1 well. At none of these factories is
the water used for drinking purposes, the water supply from
the water company's mains being provided for this purpose.
The wells, which are of considerable depth, are lined for a
sufficient distance, and have not shown evidence of surface
pollution.
