SECTION 2
SANITARY CIRCUMSTANCES OF THE BOROUGH
WATER
There are three sources of supply in the Borough, The
Northolt Greenford North Greenfor^ Central and Greenford
South Wards most of Perivale Ward and part of Hanger
Hill Ward are supplied by the Rickmansworth and Uxbridge
Valley Water Company with the exception of four roads (in
part) in the Perivale Ward and one road (in part) in the
Hanger Hill Ward which are served by the Colne Valley
Water Company. The remainder of the Borough is supplied
by the Metropolitan Water Board. These supplies are not
subject to plumbo solvent action and have been satisfac
tory both in quantity and quality. Water from public mains
is supplied to 53 318 houses with an estimated population
of 184,200.
Fifteen samples were taken from wells at five fac
tories in the Borough using water from deep borings rang
ing in depth from 300 to 600 feet. Two of the samples
taken from the same point were found to be unsatisfactory
for drinking purposes, but after the storage tank con
cerned had been thoroughly cleansed a further sample proved,
to be satisfactory. The analysis of the remainder of the
samples showed that the supplies were wholesome in character
DRAINAGE AND SEWERAGE
One cesspool was discontinued during the year leaving
22 premises not connected to the Council's sewers, Nego
tiations are at present proceeding for a further cesspool
to be abolished and the house connected to the Council s
sewerage system.
RIVERS AND STREAMS
Staff shortages have again handicapped the work of
tracing sources of pollution of the River Brent but with
staff now up to establishment it is hoped to resume this
important work.
Of 19 samples taken during the year by the County
Engineers Department of the Middlesex County Council
from sewer outfalls into the River Brent 7 were found to
be unsatisfactory. Investigations were carried out and
drainage defects in 16 houses and 1 factory were remedied
after notice by the Public Health Inspectors.
