WATER SUPPLY.
The water for the district is supplied by the Barnet District
Gas and Water Company and the Colne Valley Water Company.
With regard to the Barnet District C-as and Water Company, all
the water is chlorinated, and a pathological staff is maintained. Tho
water, in bulk, is examined daily and each pumping station once a
week. 1,697 examinations of the water were made during the year,
i.e. 188 Chemical and 1,509 Bacteriological, some of which were
analysed by an independent laboratory.
Of the Bacteriological samples representative of supply, the
percentage of first class (i.e. B.Coli absent in 100 millilitres,)
was 98.5% which is regarded as quite satisfactory.
The Colne Valley Water Company exercises constant supervision
and members of the staff are on duty day and night throughout the
year examining samples. All the water supplied by this Company is
chlorinated.
The water supply is satisfactory both from the Chemical and
Bacteriological aspect and the supply is considered adequate.
DRAINAGE AND SEWERAGE.
The town is drained and sewered on the separate system, excepting
the older portions of the district where it is a combined system.
The sewage is conveyed to an Irrigation Farm of 56 acres, but
before it is turned on the land it is screened and treated by means of
detritus and sedimentation tanks, and throe rotary filters. Pumping
is necessary for three sewers which have their outlets at a low point
on the farm. A few outlying properties arc drained to cesspools, and
part of Totteridge to the Finchley Borough Sewers.
There arc only a few earth closets in remote parts of the district.
