4. DRAINAGE AND SEWERAGE.
The soil drainage from the greater part of the District
gravitates to the main disposal works at Luxborough Lane which
were improved in 1938, extended after the war and are now nearing
the end of a further stage of improvement.
The 4 additional primary sludge digesters are almost
complete and with the new detritus tanks should be in operation
in the autumn. Improved effluent treatment area and storm water
facilities are then due to be tackled.
The completion of these improvements is expected to
result in a higher standard of purity in the effluent to be
discharged to the River Roding. So far, afair effluent has been
maintained generally (except for isolated instances during periods
of excessive rain).
The Southern Intercepting Outfall Sewer has been laid
except for the syphon under the sewer which is due for completion
this summer. Storm water disposal difficulties at the old
Buckhurst Hill Works have also been dealt with. The small
subsidiary works at Millers Lane continues to maintain a good
effluent.
A small area of Buckhurst Hill drains into the sewers of
Wanstead and Woodford, thence via Chingford and to the East
Middlesex Scheme.
Most of the Hainault Estate drains to the sewers of
Dagenham District and the Works of that Authority.
There are 4 outlying pumping stations lifting the flow
from low lying areas up to the main gravity sewers. The extra
pump was installed in Grange Hill Station during the year and the
superstructure of the new Roding Road station (as part of the
Southern Outfall Sewer Scheme). The Bradwell Road station is
due to have two pumps replaced in 1961.
Generally, there is a separate system of drainage in
the District except in the older parts where combined sewers still
exist,
