Sewage Disposal Works.
The report by your Engineer and Surveyor, Mr. A. R.
Goldthorp, B.Sc., A.M.Inst.O.E.. M.Inst.M. & Cy.E., on the
method of treatment of sewage at the Sewage Disposal
Works remains unaltered from last year with the exception
of the total dry weather flow of sewage treated at the
works which has increased to 1,425,000 gallons per day of
24 hours.
Future Works.
The Sewage Disposal Works is of insufficient capacity
to deal with the present flow and the estimate of a scheme
for carrying out the following additional works was passed
by the Council in June. This will increase the works
capacity to deal with the flow up to 1940, after which any
additional increase of sewage will be dealt with by the
Joint Board's works :—
The construction of a screening chamber with detritus
grab and gantry.
The installation of a 10" diameter centrifugal pump,
diesel engine operated.
The installation of a diesel engine to take the place of
the existing steam engine.
The construction of two flumes with flow measurement
apparatus for 3 x D.W.F., and above 3 x D.W.F.
respectively.
Erection of three storm tanks and two circular humus
tanks, six rotary filters, larger effluent carrier, additional
pipe lines, valves, etc., and an increased sludge drying
bed area.
The storm, settling and humus tanks will be sludged
with mechanical sludging apparatus.
The Council accepted Messrs. George Bell and Son's
tender of £35,341 7s. 10d. on 13th September for this work,
