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, 16.3 deg.
,, Permanent, 3.7 deg.
No B. Coli in ]00 c.c.
No Streptococci.
No acid in 100 c.c.
The supply during the year was from the
Corporation's Wells 2,233,095,210
Metropolitan Water Board in Bulk 462,709,000
2,695,804,210 gallons.
This works out, on an average population basis of 240,000
(1932), at a consumption of 30.69 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. At the sewage disposal works a.t Beddington, three
Activated Sludge plants are in operation dealing with 3½ to 5
Million gallons per day.
