A 12in. diameter foul sewer has been constructed at Thames Street, Hampton, to
replace a length of defective cast iron pipe.
The sewer survey for the Richmond Central Area is progressing satisfactorily
and will be continued into the Kew Green and Petersham areas in the coming months.
"(b) Sewage Disposal
Sewage from those parts of the Borough which were formerly in the County of
Middlesex is treated at the Mogden Works of the Greater London Council at Hounslow.
During the year Mogden Works dealt with an average daily flow of 95 million
gallons from the whole of the former West Middlesex area, discharging the pumped
effluent to the river at Isleworth Ait. This effluent has been consistently within the
standards required by the Port of London Authority.
Additional sludge digestion tanks, commissioned early in the year enabled all
sludge to be digested adequately before being pumped to Perry Oaks Works, near
London Airport, for drying and disposal to land.
Good progress was made in the construction of an automatic pumping station at
Ham, and a pumping main to convey sewage from Ham to Mogden. It is anticipated
that this work will be completed during the summer of 1970.
Sewage from the 11 square miles of the Borough, including the town of Richmond,
south of the Thames is treated at the Kew Works of the Greater London Council.
During the year Kew Works dealt with an average daily flow of million gallons
and discharged the purified effluent, again well within the Port of London Authority's
standards, into the river between Kew and Chiswick bridges.
In order to deal with increased load on the Works extension of the aeration plant
is planned for the coming year."
