New construction completed at present in hand or proposed
includes (1) detritus pits started before the war; (2) the construction
of primary sedimentation channels to treat up to 200,000,000 gallons
per day; (3) sludge digestion plants to treat up to 4,000 tons of sludge
per day, and (4) diffused air plant to treat an additional 60,000,000
gallons of sewage effluent per day.
At the Southern Outfall Works the flow of 100,000,000 gallons
per day is conveyed to the Works by two Outfall sewers and one high
level sewer each of 11 feet 6 inches in diameter. About eighty per cent
of the flow is raised by pumps nearly thirty feet and the whole flow
is passed through six sedimentation channels where the sludge is
settled out and the effluent passed to the river. The sludge is taken to
sea as described previously for the Northern Outfall Works. Recent
additions include (1) additional diesel driven pumps of a total capacity
of 300 tons per minute; (2) electrically driven pumps of a total capacity
of 600 tons per minute. New construction at present in hand or
proposed ncludes diffused air plant to treat 60,000,000 gallons per
day and sludge digestion plant to treat up to 4,000 tons of sludge per
day.
The Council maintains over 400 miles of main sewers which have
to be inspected, cleansed and repaired.
