SANITARY CIRCUMSTANCES OF THE AREA
Water Supply. The water supply is mainly derived from the
deep wells in the chalk, of the Sutton District Water Company,
situated at Sutton, Cheam and Woodmansterne. A small area in
the North Ward is supplied by the Metropolitan Water Board.
The water from all the wells of the Sutton District Water
Company is softened to under nine degrees of hardness. A high
dose of chlorine in the form of chloramlne is administered to
the water as a protective measure. Most of it is removed, later,
leaving a small residual chloramlne to pass out to public
distribution.
Approximately thirty six gallons of water per person per
day was supplied in 1959, of which approximately seven gallons
was supplied to trade, and twenty nine gallons was used
domestically.
1959 will be long remembered as the driest year for a very
long time (possibly two hundred years for the country as a whole)
and we were fortunate in our supply of water. Unrestricted
supplies were maintained for all purposes without deterioration
in quality, though naturally residents were requested to be
careful in the watering of gardens. The rainfall was 34 per cent.
below the standard average and the water consumption rose to its
highest ever peak of consumption of almost seventeen million
gallons per day as compared with an annual dally average of
approximately nine and a half million gallons per day.
Samples of the raw and treated waters are examined dally by
the laboratory at the Sutton Works. Samples are also examined
at monthly intervals by the Company's Consultant Analyst, and
monthly samples are examined in rotation by the District Councils
in the area of supply.
The supply from all sources has been satisfactory in
quality and quantity. All the dwelling houses have a direct
supply from the public mains. Below is the average of monthly
analyses.
