SEWERAGE & SEWAGE DISPOSAL
I am obliged to (a) Mr. M. S. Hebron, B.Sc., C.Eng., M.I.C.E., A.M.I.Mun.E.,
Borough Engineer and Surveyor, and (b) Mr. L. H. Thompson, A.M.I.C.E., A.M.I.S.P.
Regional Engineer, Greater London Council for the following reports: —
"(a) Sewerage
The replacement of compressed air ejectors by electric pumps is proceeding at
Sandy Lane and Lower Teddington Road, Hampton Wick and similar work will be
undertaken in 1971 at two further stations in Hampton Court Road, Hampton Wick.
Plans are in hand for the provision of relief foul and surface water sewers in
Hampton Road, Twickenham.
The surface water ditches at Dean Road, Hampton have been piped and a further
length of defective foul sewer in Waldegrave Road, Teddington has been replaced.
The sewer survey for the Richmond area is progressing satisfactorily and will be
continued in the coming months."
"(b) Sewage Disposal
Sewage for the Borough is treated at two Treatment Works of the Greater London
Council.
Kew Sewage Treatment Works receives sewage from the 11 square miles south
of the Thames (with the exception of parts of Ham). The Works treat an average
daily flow of million gallons before discharging to the River Thames, between Kew
and Chiswick bridges.
Work has commenced on improvements to the aeration plant in order that treatment
standards keep pace with the increasing load on the Works.
Sewage from the remainder of the Borough flows to the Mogden Sewage Treatment
Works, which deals with some 99 million gallons per day from the whole of the
former West Middlesex area. The effluent is discharged into the River Thames at
Isleworth.
An automatic pumping station at Ham commissioned in June 1970, conveys
sewage to Mogden, and replaces the former station which pumped to Kew.
With the exception of the period of the manual workers strike when effluent from
Mogden was only just maintained at the standards required by the Port of London
Authority, both Works have discharged an effluent consistently well within these
standards.
