WATER SUPPLY,
The water for the District is supplied by the Barnet District Gas & Water
Company and the Colne Valley Water Company.
With regard to the Barnet District Gas & Water Company, all the water is
chlorinated, and a pathological staff is maintained. The water, in bulk, is
examined daily, and at each pumping station once a week. 1,890 Chemical and
Bacteriological examinations of the water were made during the year, of which
32 Chemical and 68 Bacteriological samples were analysed by an independent
laboratory. Of the Bacteriological samples representative of supply, the
percentage of first class (i.e. Coliform organisms absent in 100 millilitres)
was 99.71%, which is regarded as quite satisfactory.
The Colne Valley Water Company exerciscs 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 aspects and the supply
is considered adequate.
DRAIMGE 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
tarika, and three rotary filters. Pumping is necessary for three sewers
which have their outlets at a low point on the farm. A few outlying properties
are drained to cesspools,' and part of Totteridge to the Finchley Borough sewers.
There are only a few pail closets in remote parts of the district.
