Drainage and Sewerage.-—Practically the whole of the District
is provided with well-constructed modern pipe-sewers, which are
properly ventilated and the sewage discharged by gravitation at
the Council's Sewage Disposal Farm on the Southern boundary of the
District, where it is received into subsidence tanks, from whence it
is pumped and distributed over Bacteria filters by means of revolving
sprinklers; it is then treated by irrigation on cultivated land, and
finally discharged into the Ching Brook. Owing to the rapid growth
of the district in recent years necessitating increased measures for
dealing with a large volume of sewage, the Council have temporarily
rented several acres of land adjacent to the farm for treatment of the
effluent by irrigation before finally discharging same into the
Ching. The drainage of a comparatively small number of houses
has to be raised by means of pumping to the higher level of the
general sewage system, and a few dwellings in the outlying and
isolated parts of the District are provided with pail-closets or
Cesspools. As far as practicable, all surface water is excluded from
the sewers, and is carried away by separate channels. Automatic
flushing and other means are adopted for cleansing the sewers as
required. A new scheme for the efficient treatment and disposal of
sewage by modern methods, coupled with the relief of various overtaxed
sewers, has been prepared by the Council, and considered by
the Ministry of Health.
This will give greater facilities for the satisfactory drainage of
the district, provide means for the further development of a considerable
area of building land, and at the same time permit of a much
higher degree of purity of the sewage farm effluent.
Owing to the favourable situation of the district, which is thereby
likely to become more populated, an undertaking such as this should
ensure a higher standard of health and be a definite factor in the
well-being of present and future residents.
Closet Accommodation.—There are in the district 33 dwellings
not connected with the public sewer. Of these 22 drain into cesspools.
Two have sink waste and surface drainage discharging into
streams. Nine isolated cottages are without drains. There are 4
water closets without flushing cisterns, 39 pail closets, and no privies.
All other houses in the district are provided with at least one
properly constructed W.C.
Scavenging.—The weekly collection of dust and house refuse is
carried out efficiently.
