SECTION 2
sanitary circumstances of the district.
(a) WATER SUPPLY.
Water is supplied by the South Essex Water Company
from deep wells in the chalk at Dagenham, Chadwell Heath,
Ilford and Barkingside. Analytical particulars of a sample
appeared in my Report for 1923.
(b) RIVERS AND STREAMS.
The Rivers and Streams of the district come within the
jurisdiction of the Essex Sewers Commissioners (who are the
Tidal Flush and Flood Water Drainage Authority) and the
Port of London Authority, who are the recognised Navigation
Authority for the Thames, as defined by the Port of London
Consolidation Act, 1920, and who have also certain powers as
to the fouling of streams, etc.
The Council's attention during the year was directed to
the standard of purity of their sewage effluent as discharged
into the Roding, a tributary of the Thames.
(c) RAINFALL.
The rainfall for the year ended December 31st was 24.7
inches. Rain fell on 179 days throughout the period in
question.
(d) SEWAGE.
A water-carriage system is general, except in certain parts
referred to elsewhere. Over the greater part of the area there
is a separate sewage and storm water system.
Sewage is treated within the district by precipitation and
sedimentation, the resulting effluent being discharged into the
River Roding. The sewage disposal works (originally erected
in 1888 for a population of some 20,000 inhabitants) are now
