WATER SUPPLY.
The major area of the district is supplied with water from the mains
of the Barnet District Water Company, and the remainder is served by the
Colne Valley Water Company.
All water supplied by the Barnet District Water Company is chlorinated.
A laboratory staff is maintained and the water is regularly tested at all
stages. During the year, a total of 1 ,637 bacteriological and 252
chemical examinations of the water were made by the Company's own staff.
1,315 of these samples were representative of the supply, and, 99.9% were
found to be free from B.Coli.
Ninety-eight samples representative of supply were submitted for independent
analysis and all of these were found to be free from B.Coli.
The Colne Valley Water Company exercises similar controls over its
supplies. Two samples of water were taken by the Department, from the
Barnet District Water Company's supply and submitted for analysis with
satisfactory results in each case.
