Public Health Act, 1925: Not adopted, but under consideration.
Sanitary Circumstances of the District.
Water.—The water service of the district is supplied by the
Metropolitan Water Board and continues to be of good quality.
Rivers and Streams.—The only river in the district is the Boding
into which the effluent from our sewage disposal works is discharged.
The most recent inspection of the latter yielded the following results:—
Effluent from river above Works 3.2 per cent.
Effluent from river below Works 3.4 „
Sprinkler Effluent 3.6 „
Contact Bed 6.4 „
The Standard Impurity figures are:—
Passable Effluent 10 per cent.
Good Effluent 7 „
River water which may be used after
infiltration for drinking purposes 2.5 „
Not to be so used 3.5 „
Drainage and Sewerage.—The Wanstead Council is fortunate in
governing a district where the "lie of the land" permits the whole
of the surface-water and sewage to be discharged by gravitation without
the expense of pumping or lifting. The drainage system is "combined,"
as far as domestic sanitation is concerned, i.e., the rainwater
and sewage are led away by the same pipes. The surface drainage
of the streets, however, is in most cases carried off by an entirely
separate system of drains, discharging into open water-courses or
ponds, which provide also a means of drainage for the numerous open
spaces of t-he district.
But in the Northern part of Wanstead the greater part of the
surface-water is collected by the brick conduit of 3 ft. 6 in. diameter,
which extends from the Eagle Pond overflow eastwards through the
Cowley Road and Nightingale Lane depression, across Nightingale
Farm to the river Roding. Lower down, into the same river, various
discharges of surface-water take place, as e.g., into the ditch on the
east side of Redbridge Lane, below the Rectory.
Turning now to the sewage system, the main outfall-sewer
(2 ft. 4 in. by 3 ft. 6 in.) of Wanstead runs from the northern
boundary in a southerly direction through the fields of Nightingale
Farm at the rear of the houses on the east side of Buckingham
Road; it strikes Redbridge Lane at the right-angled bend below the
