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 1,988,432,652
Metropolitan Water Board in Bulk 627,153,000
2,615,585,652 gallons.
This works out, on an average population basis of 245,000
(1934), at a consumption of 29.24 gallons per diem per head.
The low rainfall and consequent drought entailed warning
being issued to the public to economise supplies and in the latter
part of the year it was found necessary to prohibit the use of water
for gardens and sports grounds.
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
£50,000 has been expended in maintenance and laying of new
main sewers and surface water drains and a further loan for £35,000
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.
