the very unsatisfactory condition of the sewers, several openings were made and an
inspection took place during 1890 by the Paving and Sewers Committee.
"Beyond giving an instruction to have some of the sewers cleansed no
resolution was then come to.
"In the spring of the present year, owing to further complaints embracing
drain stoppages, flowing of sewage back into premises, and fonl smells throughout
the district, and having regard to the shallowness, inadequate gradients, and
general bad construction of the Vestry's sewers there, it was resolved to have a
survey made of the District and plans prepared for a thorough system of
re-drainage.
"Having been allowed the necessary assistance in September, plans, sections,
and detail drawings have since been prepared, which are submitted herewith for
your approval, and an approximate estimate is appended to this report.
"It is proposed to construct a new 3-ft. 9-in. by 2-ft. 6-in. egg shaped brick
sewer, commencing at the Hackney Road end of Tuilerie Street, by connection with
the new Main Sewer belonging to the London County Council, passing from thence
through Tuilerie Street, Holms Street, Boston Street, across Dove Row, through
Jacobin Street and Whiston Street to the corner of Nicholl Street, allowing a
gradient throughout of 1 in 120.
" The depths from the surface would be : at Hackney Road, about 24§-ft., and
at Nicholl Street about 8^-ft.
" A branch sewer 3-ft. 6-in. by 2-ft. 4-in, also of brickwork, and egg shaped,
would be connected to the sewer referred to, at the junction of Audrey Street with
Boston Street. It would pass through Audrey Street and be connected to the
existing sewer in Goldsmith's Row. The average depth of this sewer would be
between 10 and 11 feet, and the gradient 1 in 120.
" It is proposed to construct 15-in. Pipe Sewers through portions of Dove Row
and Jacobin Street at average depths of about 5-ft. 9-in. and 7-ft. respectively, and
with gradients of 1 in 128, and 1 in 120.
" The whole of the remaining sewers would be constructed of 12-in. pipes as
detailed hereafter, at depths varying from 5 feet to 17 feet respectively, and
gradients generally of 1 in 120.
" Abundant means of road surface ventilation, and access by manholes and
side entrances for cleansing purposes and inspection have been provided.
"The following is a summary of my approximate estimate of the cost of this
section of the proposed scheme.
