Sewage disposal is very efficient. The Northern Sewage
Works deal with about 240,000 gallons of sewage per day and the
Southern Works about one-and-a-half million gallons per day.
Treatment is by precipitation with sulphate of iron, followed by
sedimentation and filtration of the effluent by intermittent downward
filtration or over contact beds. At the Northern Works
the effluent is passed through a "Humus" tank before being
finally discharged into the Brent. The sludge is treated with lime
and pressed into cake for which there is a demand as a manure for
agricultural purposes. Any sludge-cake which may accumulate
at the Southern Works is burned in the refuse destructor which
adjoins.
Closet Accommodation. Excepting a temporary building
and two small cottages which are at a distance from a sewer the
whole of the houses in the Borough are supplied with water closets.
As a rule there is one water closet to each house, but in many
instances houses have been sub-let so that more than one family
may use the same convenience. Where, however, a house is
permanently converted into flats separate accommodation for each
family is required.
Scavenging.—By the Ealing Corporation Act all premises
must be supplied with a sanitary dustbin of a suitable size and with
a proper cover. This requirement is rigidly enforced.
Removal of household refuse is carried out weekly. A
destructor comprising ten cells, which is situated at South Ealing,
adjacent to the Sewage Works, receives and burns the refuse from
the whole district.
