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 1949.
Hornsey is supplied from two sources :—
(a) Water from the New River, treated at the Board's filtration
works at Hornsey, 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 supply 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.
