Section C.—Sanitary Circumstances.
Water Supply.
The district is in the supply area of the Sutton District Water
Company. The supply is derived from deep wells in the chalk
at Sutton, Cheam and Woodmansterne and is augmented at
intervals by water derived from river sources.
The Cheam well, which had been closed since 1936, was put
into supply again in June, 1938.
The arrangements for controlling the quality of the supply
were given in previous reports. These include routine sampling
by the local authorities in the distribution area upon an agreed
rota. Further samples are taken as circumstances indicate.
Nine samples were taken by this Department during the year, 6
of which were submitted for bacteriological, and 3 for chemical,
examination. They indicate a high degree of purity. All showed
absence of bacillus coli in 100 ml., except one in which there was
1 organism in 100 ml., but this slight variation from the high
standard of the remainder was in a water fed through a storage
tank. A sample taken direct from the rising main from the same
premises was of the high standard referred to.
Drainage and Sewerage.
The district has separate sewers for foul and surface water.
Sewage is disposed of by an arrangement with the Croydon
Corporation whereby the whole of the sewage of the district is
pumped to the works of that authority.
The scheme for drainage of the Surrey County Council's
Smallholdings was completed early in 1938. By this means cesspools
in connection with 61 premises were abolished.
A scheme has also been prepared for the elimination of the
cesspools at the Oaks Estate. This was put in hand early in 1939.
