the year at a cost of £1,411. The sludge vessel J. H. Hunter was damaged as the
result of a collison with an ocean-going liner (s.s. Surrey), and was repaired at a cost
of £2.556.
Northern
outfall.
The work of extending the pier at the Northern outfall to accommodate the
larger type of sludge vessels was completed by C. J. Wills and Sons, Limited, at a
cost of approximately £5,826. The s.s. Surrey, which collided with the s.s. J. H.
Hunter, as stated in the previous paragraph, also caused serious damage to the pier
and the recently finished extension. Steps are being taken to put in hand the
necessary repairs. The general work of repairing the pier, which is being carried
out over a period of vears, was continued during the year at a cost of approximately
£1,200.
Some of the machinery at the outfall, which had been installed for 36 years,
was practically worn out. Tenders for four new pumping engines and two surface
condensing sets were invited, and the tender of Peter Brotherhood, Limited, of
Peterborough, amounting to £5,549, was accepted.
Arrangements have been made for the demolition of the disused liming station
at the outfall.
The painting of the overhead sludge tanks was advanced beyond the normal
time for repainting in order to provide additional employment, and the Council
on 9th September, 1925, accepted the tender of Arthur H. Inns, Limited, amounting
to £362 1s. 1d. for the work. For the same reason the repair or roads at the outfall
was put in hand at an estimated cost of £1,500.
The construction of a new concrete bed for draining refuse from the screens at an
estimated cost of £350 was commenced.
Southern
outfall.
The overhaul of the main beam engines and pumps at the Southern outfall has
been proceeding continuously since 1915, when completion of the engines and pumps
in the new engine house offered an opportunity for stopping the old machines in
rotation. Up to date the work has cost approximately £9,000, of which £2,000
was sanctioned during the year 1925.
In order to provide additional employment the Council authorised the repairs
of roads at the outfall at an estimated cost of £950 and the painting of the interiors
of the precipitation engine and boiler house, etc., at a cost of £1,031.
Abbey Mills
pumping
station.
Apart from the work in connection with the enlargement of Abbey Mills pumping
station which is referred to under the heading of "Flood relief works," the works
undertaken at the station during the year apart from repair work included the
filling in and raising the long wall forming the bank of the Channelsea river which
passes the station on its eastern side, and the repainting of the station, which latter
works were expedited with a view to providing employment.
Outfall,
intercepting
and main
sewers.

The work of removing from the sewers deposits which accumulate there is one
of considerable magnitude. For this purpose the county is divided into four districts,
each district being made the subject of a separate contract. Contracts are
based upon prices for the cartage and disposal of the deposit which is removed from
the sewers bv the Council's staff. The cost of this work in 1925 was approximately
£3,350.
