SANITARY CIRCUMSTANCES OF THE AREA.
Water.
The district is supplied with water almost entirely from
the mains of the Barnet District Gas and Water Company.
The water is derived from deep wells in the chalk, and is
of a high degree of purity, but owing to its source it is,
unfortunately, comparatively "hard." The supply is constant
and the average quantity supplied to residents in the
district is about 25 gallons per head per day. A small part
of the Hampstead Garden Suburb is supplied with water
by the Metropolitan Water Board.
Rivers and Streams.
The streams in the district have been inspected from
time to time, and on no occasion have they been found to
be polluted.
Drainage and Sewerage.
Mr. Percival T. Harrison, M.I.C.E., the Council's
Engineer and Surveyor, has kindly supplied me with the
following details:—
Sewerage.
The Finchley sewage is collected by tributary sewers
into two main sewers which discharge separately at the
Sewage Disposal Works at two different levels.
The low level trunk sewer, terminating in that portion
of the works adjoining Coppetts Road, proceeds through the
Rough Lots, crosses the Great North Road, and thence
along Squires Lane and Long Lane to Ballards Lane; proceeding
then along Lovers Walk to the north-west end of
Lansdowne Road, at which point there enters the recentlyconstructed
sewer from Totteridge Lane, and the sewer,
now under re-construction in part, from Waverley Grove
and East Finchley. At Waverley Grove the latter sewer
receives the sewage from Broughton Avenue Pumping
Station. This station, on the abolition of the temporary
pumping Station at Addison Way, will receive the sewage
from the Hampstead Suburb Trust area and from Village
Road, etc., a large part of which already flows into it.
