(b) Snakes Lane West
The soil and surface water sewers in the lower section of Snakes Lane
West have inadequate capacity and a scheme was prepared for the
renewal and enlargement of these sewers, particular attention being
given to flooding which occasionally occurs in Linden Crescent and to
the future effect of the adjacent comprehensive development area.
(c) St. Barnabas Road Screening Chamber
This screening chamber, through which the sewage flows from the
high level portion of the area served by Eastern Sewage Works, is very
old and its structural condition causes increased concern. Also, the
present screen requires regular manual cleaning and attention. It was
therefore decided that a scheme should be prepared for a new structure
and screening arrangments, it being intended that some form of mechanical
screening should be adopted to avoid the present unsatisfactory
manual system. The preparation of the scheme was well advanced at the
end of the year and it is intended to invite tenders as soon as the
relevant details have been completed.
Sewage Disposal
(a) Eastern Sewage Works
Following the completion of the second stage of the reconstruction
and improvement scheme in 1962, the standard of effluent discharged
to the River Roding was generally satisfactory but careful attention
had to be given to certain conditions affecting the effluent particularly
in times of heavy flow
The primary sludge digestion tanks periodically require emptying and
cleaning out and this is a major and expensive operation. The work
became urgently necessary and was arranged to be undertaken for completion
by the end of April, 1964.
(b) Southern Sewage Works
A tender amounting to £203,000 was accepted for the second stage
of the reconstruction and improvement scheme which comprises sludge
coilfiltration, renewal of media and equipment in the filter beds, the
improvement of storm tanks, the reclamation and landscaping of the
old sludge drying beds and adjacent areas, and the provision of improved
staff facilities. Work commenced in November, 1963, and was
due to last 15 months.
