Prompt measures were taken to abate the nuisance,
and the tip was at once closed for house refuse.
The face of the refuse already there was sealed by the
deposit of a thick bank of earth and the water was deodorized
with over a ton of chloride of lime, which effectually
remedied the nuisance, and in a short time the water
became quite clear.
Drainage, Sewerage and Sewage Disposal.
During the past few years practically the whole of the
drains of the older houses in the district have been reconstructed
and connected to the public sewer, with the consequent
abolition of cesspools and privy pits and the installation
of water closets.
All new houses are so connected at the time of erection.
The work of construction is under frequent inspection
and all drains are laid on a concrete foundation, with
inspection chambers at each change of direction.
The drains are tested with water pressure before being
covered in and with smoke on completion.
The district is divided into areas for the purpose of
sewerage; each area discharging its sewage by gravitation
into a Shone Pneumatic ejector, from which the sewage is
lifted by compressed air to the disposal works in Hanworth
Road.
The installation at the sewage disposal works comprises
a screening chamber, detritus tanks, a hydrolitic
tank, and triple contact beds.
The sewage is delivered on to the primary and
secondary contact beds by means of a travelling distributor.
