Water Supply. Rivers and Streams, Drainage

SANITARY CIRCUMSTANCES OF THE DISTRICT.
Water Supply.
Ealing is supplied with water by the Metropolitan
Water Board. A supply reservoir for supplying
a portion of the town by gravitation during the night
is situated at the highest point in the Borough on the
top of Hanger Hill.
Rivers and Streams.
The Brent forms the northern boundary of the
district and here it receives the effluents from the
Wembley Sewage Works and Ealing Northern Sewage
Works.
Drainage and Sewerage.
Ealing being a town of comparatively recent development
there are only three small areas which can be
said not to be completely supplied with modern drainage
and these areas previously to the outbreak of war were
being quickly redrained in accordance with the requirements
of the Byelaws. The sewerage is suitable to the
needs of the whole district and consists of two systems,
one taking by far the larger portion of the sewage and
discharging into the Southern Sewage Works on the
Southern boundary and the other discharging into the
Northern Sewage Works on the northern boundary.
The Sewage Works penorm their functions admirably,
the process being at both places precipitation by means
of sulphate of iron followed by intermittent downward
filtration or treatment on contact beds.
