mains water supply carried out by the Metropolitan Water Board are issued from
time to time and these have shown the water to be of satisfactory quality. The
reports also show the state of purity of the water supply at its sources and

SEWERAGE AND SEWAGE DISPOSAL
The sewerage system for Brentford and Chiswick is mainly a "separate"
system in which surface water drainage and foul drainage are kept separate with
two sets of drains along streets to which the various connections can be made.
In a few of the older areas of the Borough no surface water drainage exists
and in these areas the foul and surface water drainage from properties is all
taken into the foul sewer while surface water drainage from highways is taken
into soakaways
The surface water drainage system is split into areas throughout the Borough
and each area has an outfall into the River Thames There are approximately
18 outfalls of this kind along the length of the River within the Borough.,
The foul drainage system is based on the two areas of Brentford and Chiswick,
each area draining to one point within its boundary The Brentford area drains
to Town Meadow Depot and the Chiswick area to Corney Road Depot Before the
advent of the West Middlesex Drainage Board the sewage received at Town Meadow
Depot was pumped to a sewage disposal plant situated at Clayponds Gardens, and
the sewage received at Corney Road Depot was treated at a plant within the Depot,
both plants having outfalls into the Thames for effluent Since the West
Middlesex Drainage Board came into operation, the two sewage plants in the
Borough have ceased to operate and the two Depots were connected to a trunk
sewer owned by the Board and running through the Borough The sewage from the
Borough is carried by the trunk sewer to Mogden Works and treated and disposed
of there It must be noted that the drainage system joins the trunk sewer in
only two places
