V.—SANITARY CIRCUMSTANCES.
Rivers and Streams.
Periodical inspections of all streams and watercourses
in the district are made by the sanitary
inspectors, and during the year one instance of pollution
of a minor character was remedied after service of
informal notice.
Drainage and Sewerage.
The main drainage of Bromley joins that of the
undertaking of the West Kent Main Sewerage Board,
whose purification works are at Dartford. Sewerage is
there precipitated by gravitation before being discharged
into the River Thames.
The town's surface water drainage is separate from
the system for foul drainage.
There are 22 cesspools in the unsewered portion of
the Borough, otherwise there is water carriage.
Water.
A piped supply is general throughout the Borough,
and comes from the Metropolitan Water Board's deep
chalk well at Short lands valley. The supply is sufficient
and of high grade purity, and is accepted as a standard
of purity for deep well water. Particulars of reservoirs
within the district are given in my Annual Report for
1930 (page 35).
Scavenging.
During the year 1931 one 2-ton electric vehicle was
purchased, the refuse for the greater part of the year
being collected with the following transport:—
3 one-ton covered low-loading petrol vehicles.
3 two-ton covered low-loading electric vehicles.
1 high-loading horse-drawn vehicle.
All refuse during the year was disposed of at the
Refuse Destructor by incineration, and necessity for
improvement in disposal did not arise during the year.
