I am indebted to the Borough Engineer, Mr. G. F. Carter,
for the following information:—
A constant supply of water was maintained throughout the
year, and has been satisfactory both in quality and quantity.
Monthly analyses of the water were made at the five pumping
stations, and in many cases at more frequent intervals. The
Corporation's wells are all in the chalk, and a sample analysis
is as follows:—
Clear and bright.
Hardness—Temporary, 16.8 deg.
,, Permanent, 3.7 deg.
No B. Coli in 100 c.c.
No Streptococci.
No acid in 100 c.c.
The supply during the year was from the
Corporation's Wells 2,247,541,827
Metropolitan Water Board in Bulk 568,568,000
2,816,109,827 gallons.
The low rainfall caused some anxiety but at no time during
the year was it necessary to curtail the supply.
This works out, on an average population basis of 247,000
(1933), at a consumption of 31.23 gallons per diem per head.
Rivers and Streams.
There are only small streams or ditches. These have been
kept in a good state.
Drainage and Sewage.
Extensions of the sewerage system have been made to keep
pace with the growth of the Borough, in particular in the new
area of Addington which was added to the Borough in 1928. Over
£36,000 has been expended in main sewers and surface water
drains and a further loan for £23,580 for additional sewage work
in the Borough is being sought. At the sewage disposal works at
Beddington. three Activated Sludge plants are in operation dealing
with 3½ to 5 million gallons per day.
