B. Coli (presumptive) absent in 90 c.c. Further tests
showed that these were not typical B. coli.
(ii) Drainage and Sewerage.
The Borough Engineer has supplied me with details of
drainage work carried out during 1946 as follows :—
The old 9-in. surface water sewer in Alers Road and
Brook Lane was replaced by a new 15-in. and 18-in. sewer to
accommodate the surface water discharge from the Council's
Alers Road Housing Scheme and the surrounding drainage
area.
A new 15-in. x 18-in. surface water sewer was laid from
Hurst Road to the River Cray to provide an outfall for the
Council's proposed Hurst Place Housing Scheme (approximately
one-third of a mile).
A new 7-in. foul sewer was laid to connect the properties
in Bournewood Road and Alliance Road to the Council's
East Wickham Pumping Station. These properties were
originally drained into the Metropolitan Borough of Woolwich.
Foul and surface water sewers were laid on the Westwood
Lane and Alers Road Housing Schemes.
2. Rivers and Streams.
No serious case of pollution of rivers or streams was found
during the year.
3. (i) Closet Accommodation.
All the closet accommodation in the Borough is on the
water carriage system.
(ii) Public Cleansing.
Eight cesspools were emptied a total of 23 times.
One cesspool was abolished and the property concerned
connected to the main sewage system.
