"This is a clear and bright water free from odour and
taste and neutral in re-action. It is hard in character,
free from metals, and contains no excess of saline matter.
Both organically and bacteriologically the water is
of a high degree of purity and is pure and wholesome water
suitable for public supply purposes."
Sewerage and Drainage.
The district is generally sewered on the separate system, the
foul sewage being treated at the Sewage Disposal Works at
Brunswick Park Road and the surface water drainage taken to
Pymmes Brook by a number of brooklets or watercourses.
Sewage Disposal.
The sewage is delivered at the Sewage Disposal Works which
are situated at the junction of Brunswick Park Road and Osidge
Lane by five main sewers and two rising mains from pumping
stations.
The new Disposal Works, designed for a dry weather flow
of 1,250,000 gallons a day, is about to commence full treatment.
They consist of Screen and Detritus Tank with Mechanical
Dredger, Preliminary Settlement Tanks with Mechanical Scrapers,
Secondary Settlement Tanks, Aeration Tanks (Simplex Surface
Aeration System), Final Settlement Tanks and Percolating Filters,
the effluent passing into Pymmes Brook. The sludge is pumped
to Primary and Secondary sludge Digestion Tanks from whence
it gravitates to Sludge Drying Beds before being disposed of on
the land.
Samples of the effluent are taken by the Lee Conservancy
Board.
Refuse Collection and Disposal.
Everything possible is done to control the conditions unfavourable
to health and so prevent the outbreak or spread of
disease.
