Water Supply
All houses in the Borough enjoy a piped water supply, the majority of houses
being supplied by the Sutton District Water Company. A few houses near the northern
boundary of the Borough are supplied by the Metropolitan Water Board, and there are a
number of private wells supplying hospitals, factories and a school.
The average Fluoride content of the water supplied is 0.1 parts per million.
The Sutton District Water Company draws its supplies from deep wells in the
chalk at Sutton, Cheam, Carshalton and Woodmansterne, and also a bulk supply from wells
at Epsom. The water supplied by the Sutton District Water Company is softened to less than
9° of hardness, Clark's Scale, this being approximately 130 parts per million total hardness.
I am indebted to Mr. G.L. Ingham, B.Sc., C.Eng., F.I.C.E., F.I.W.E., Engineer
and Manager of the Sutton District Water Company, for the following information relating
to 1970:-
1. The total rainfall recorded at Burgh Heath Reservoir during the year
1970 was 827mm. (32.55 ins.) this being an increase of 43mm. (1.67 ins.)
when compared with the standard 35-year average of 784mm. (30.88 ins.)
2. The pattern of weather in the early months of 1970 was very similar to
that of the preceding year. January was mild but February and March were
comparatively cold with some snowfalls experienced in both these months.
A moderate snowfall also occurred towards the latter part of December
and temperatures generally were low. All the above rainfalls and standard
averages refer as in previous annual reports to the records taken at Burgh
Heath Pumping Station, as this station is assumed to give a reliable
indication of the mean rainfall for the Company's catchment area as a
whole.
3. At the commencement of 1970 the underground water levels were relatively
low, but increased rapidly during February and March, reaching their peak
in April. Underground levels generally were somewhat lower than for the
preceding year, which were exceptionally high due to the extreme rainfall
experienced in the autumn of 1968.
4. Supply and Consumption - Because of the warm and dry weather experienced
during the early summer of 1970 the consumption of water was exceptionally
high and broke all previous records. The comparable figures for 1969/70 are
as follows:-
