The new works include a new intercepting sewer from
the southern portion of the. district, 1,130 yards long of
15in, 18in, and 21in. stoneware pipes, 200 feet 0i 24in
concrete tubes, and 200 feet of 15-inch cast-iron pipes;
a new cottage for the foreman, a tool-house, and stores
room, an engine-house and pump-well, and a 5-horse
power oil engine, and 3in. centrifugal pump. These
works were executed by contract. The Council have
carried out the sewage works extensions by means of
direct labour. These consist of two sets of receiving
chambers on the high and low level outfalls, 2 detritus
and sedimentation tanks, having combined capacities of
352,000 gallons, and a storm-water sedimentation tank
of 120,000 gallons capacity. Also of 10 circular sprinkler
filters of 65ft. diameter, 3680 yards super in area, 4ft. 6in.
in depth, and with 3 feed chambers, and all the necessary
channels and humus tanks. There are also three stormwater
filter beds, 3ft. in depth, with an area of 2,700 yards,
and six sludge-draining lagoons, each 50ft. by 50ft., with
under-drains and filtering media over 18in. deep, the
sludge-draining being conveyed to the pump-well and
pumped into the sedimentation tanks for re-treatment.
Land adjoining the works, consisting of an area of 11
acres in extent, has been purchased by the Council, and
will be used for further treatment of the filtered effuent.
The effluent from the new filters has been very satisfactory
indeed, and the completed works are a credit to
the district. The scheme was prepared by the Council's
Engineer and Surveyor, Mr. H.Walker, and cost £
13,600
to construct. It should provide for the efficient treatment
of our sewage for many years to come, allowing
for a considerable annual increase of population and a
probable extension of the area of the. Council's district.
REMOVAL AND DISPOSAL OF DUST.
There is a weekly collection of house refuse in the
Council's own carts. It is carted to the Sewage Disposal
Works, tipped, and as much as possible burnt.
But, with the growth of the district, it becomes more
difficult every year to deal effectually with the refuse and
a dust destructor will certainly have to be provided before
long in order to dispose of the kind of refuse which cannot
be dealt with in any other way, and which now collects
at the Works and materially detracts from their
generally tidy and well-kept appearance. I would like
to suggest to the Council that when purchasing a destructor
they might at the same time with advantage
