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, and a pathological staff is maintained. The water, in bulk, is
examined daily an' each pumping station once a week. 1,722 examinations of the
water were ma"e during the year, i.e. 199 Chemical and 1,523 Bacteriological,
Of the Bacteriological samples, 1,377 were representative of supply and the
percentage of first class (i.e. B.Coli absent in 100 millilitres,) was 99,3%
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 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.
