SANITARY CIRCUMSTANCES OF THE AREA
WATER SUPPLY
The water supply for Hornsey is provided by the Metropolitan
Water Board.
The supply has been satisfactory both in quantity and quality
during the year 1947.
Hornsey is supplied from two sources:—
(a) Water from the New River, treated at the Board's filtration
works at Stoke Newington, and
(b) River Thames water stored in Littleton reservoir and treated
at the Board's filtration works at Kempton Park.
Water is pumped from these works into service reservoirs at Crouch
Hill.
Samples of water are collected on five days in every week at each
stage of the purification process and tests include physical, chemical
and microbiological examination.
The water supplied to this area is not plumbo-solvent.
All new and repaired mains are chlorinated before being restored
to use and samples of water from them are tested bacteriologically to
ensure efficient disinfection.
