100 feet by 32 feet with a capacity of 96,000 gallons, the water supply
being from local wells and the Metropolitan Water Board. The water
is filtered by Candy pressure filters, giving a turnover of approximately
six hours, and sterilization is achieved by chlorine gas treatment.
Daily recordings are made of available and residual chlorine in
the water, the pH value, and the shallow and deep-end temperatures.
In addition, bacteriological samples of the water are taken each month,
and all during the year, have proved satisfactory.
3. Sewerage and Sewage Disposal.
The Borough is sewered on a partially separate system, with the
drainage from roads discharging directly into the river through surface
water sewers. The soil sewers drain to the purification works of the
Richmond Main Sewerage Board, which receives sewage from the
Boroughs of Richmond and Barnes.
The civil engineering works of reconstructing the primary digestion
tanks, together with extensive ancillary works, including a new boilerhouse,
had been completed by the end of 1964, and the purification
plant should ensure that a high standard effluent is discharged into
the River Thames without causing a nuisance to residents in the
neighbourhood.
4. Public Health Inspections.
The wide range of public health inspections is shown in Table 18
and routine visits to food premises and for food sampling were maintained
throughout the year.
Table 19 shows that many improvements are effected by informal
action and without the need to resort to statutory procedures. Nearly
all formal notices served under the Public Health and Housing Acts
arose because of delay in carrying out works of repair.
The number of complaints (Table 20) increased by 121 on the
figure for the previous year. Every effort is made to ensure that each
complaint is investigated within twenty-four hours of its receipt.
No legal proceedings were instituted by the Council to enforce
property repairs.
5. Disinfection and Disinfestation.
There has been no increase in the treatment of premises after cases
of infectious disease or of bed-bug infestation. The fumigation of
clothing before being sent abroad is carried out to assist members of
the public to satisfy Post Office regulations, and a small charge is made
for the treatment.
A summary of the work done is contained in Table 21.
6. Atmospheric Pollution.
The fifth Smoke Control Order came into operation on 1st October,
1964, and the Council made the No. 6 Smoke Control Order during
the year which comes into operation on 1st October, 1965.
