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 Gas and Water Company, all the water is
chlorinated, ana a pathological staff is maintained. The water, in bulk, is
examined daily and each pumping station once a week. 1,501 examinations of the
water were made during the year, i.e. 207 Chemical and 1,294 Bacteriological.
Of the Bacteriological samples, 1,206 were representative of supply and the
percentage of first class (i.e. B. Coli absent in 100 millilitres), was 98.7.
In addition to the above 32 Chemical and 60 Bacteriological examinations were
made by Dr. Suckling of the Counties Public Health Laboratories and all samples
were reported free of B. Coli in 100 millilitres.
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.
DRAINAGE AND SEWERAGE.
The Town is drained and sewered on the separate system, excepting the older
portions of the district where a combined system obtains.
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 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 earth closets in remote parts of the district.
SANITARY CONDITIONS AND WATER SUPPLY OF SCHOOLS.
There are eight public elementary schools in the district, viz:- Arkley
Church of England Infants School; Byng Road County Council School (Junior Mixed
