Croydon, from being originally a purely residential town,
is assuming more and more an industrial character.
Water.
The water supply is drawn from deep wells in the chalk.
These wells are situated at Surrey Street, Stroud Green, Waddon,
Selhurst, and Addington. A portion of the northern side of the
Borough obtains water supplies from the Metropolitan Water
Board.
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 10.7 deg.
,, Permanent, 3-2 deg.
No B. Coli in 100 c.c.
No Streptococci.
No acid in 100 c.c.
Trace of peaty debris and fine sandy mineral matter.
The supply during the year was from the
Corporation's Wells 2,184,144,228
Metropolitan Water Board in bulk 503,156,000
2,687,300,228 gallons.
This works out, on a population basis of 225,000, at a consumption
of 32.722 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 Sewerage.
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 £25,000 has been expended in main sewers and surface
