The vast majority of premises in the area are drained to
the public sewers, but there remain a few served by cesspools
or pail closets. A scheme is being prepared to provide main
drainage for a number of these.
Water Analysis
The Bedfont and Feltham Wards of the District were
supplied by the South-West Suburban Water Company and
the Hanworth Ward by the Metropolitan Water Board. The
water supplied to this area by the South-West Suburban
Water Company was taken by the Company from the
Metropolitan Water Board. The water was derived from the
River Thames, purified in the storage reservoirs at Littleton,
Staines, and Walton, and filtered and chlorinated at the
Hampton Works. The water supply was satisfactory both as
regards quantity and quality.
Samples for bacteriological and chemical examination
were taken by the Metropolitan Water Board at all stages
of purification at least 5 times each week and 13 raw
water and 247 treated water samples were taken by the
South-West Suburban Water Company including 14 in the
Feltham area. In addition 2 samples were taken by my
department.
