Water Supply.
The water supply through the District is
furnished by the Metropolitan Water Board and is
a constant supply of excellent quality. No samples

During 1937, (the bacteriological standard of water going
into supply did not fall below 100%, and every sample showed
Bact. coli absent from 100 ml. with an average colony count of
2.2 per ml.

Drainage and Sewerage.
There have been no important extensions to
sewerage during the year. With regard to sewage
disposal, important extensions to the works at
Surbiton and Ruxley are proposed and at the time
of writing, applications for loan have been made to
the Ministry of Health.
The sewage works at Ruxley is situated in the
Epsom Urban District; but it also serves the parish
of Chessington.
