It will be seen that the flow in the River from
Abridge, after it has passed through most of the rural
part of its course, downwards, is equivalent to a
satisfactory sewage effluent.
The position in respect to the main Sewage Works
above and all works below Abridge is as follows :—
(1) Sewage Works above Abridge.—The three
main sewage works nearest to Abridge are :—
Epping Urban (Southern) Sewage Works.—These
Works, which discharge an effluent into a tributary
of the River Roding approximately 2¾ miles above
Abridge, were remodelled in 1935. Since 1/1/37
the effluents have been satisfactory.
Theydon Bois Sewage Works (Epping Rural).—
These works discharge an effluent into a tributary
of the River Roding approximately 3½ miles above
Abridge. Samples give unsatisfactory results.
Approval has been given by the Ministry of Health
to a scheme for providing a new sewage works on a
new site situated about one mile above Abridge.
Stanford Rivers Sewage Works (Ongar Rural).—
These new works completed in 1937 discharge
very satisfactory effluents into the River Roding
about 7 ½ miles above Abridge.
