SEWERAGE AND DRAINAGE WORKS
The following are the principal works executed in connection
with the sewers, &c., (luring the Year: -
Boundary
Row.
A new 12 inch pipe sewer has been laid in this thoroughfare,
which has now a deep modern drain through its whole length,
with a good fall towards the main sewer in Blackfriars Road.
The houses on the south side of Boundary How have hitherto
drained into an old drain in the rear of the premises, the drain
is in had condition, and being near the surface of the ground, no
proper fall could be given to the house connections. In laying
this new sewer, junctions were left for every house, and their
positions clearly marked, so that they could be opened down upon
when a connection was required to be made. 1 hope in a short
time that all the houses in Boundary Row will drain into this
new sewer—the old drain can then be dealt with.
The total length of the Boundary Row sewer is about 300 feet,
but about 100 feet of this length was laid some time since. In
consequence of the nature of the ground, a large quantity of
timbering had to be left in the sewer cutting, it being considered
inadvisable to take it out, a flushing box was constructed at the
upper end of the sewer, so that the sewer could be cleansed from
the nearest hydrant.
Marlborough
Street.
The drainage arrangement in this thoroughfare demanded
special attention, there' being no less than two large brick
sewers which received the drainage of the buildings in this street.
One sewer, which runs for a short distance up the centre of the
roadway and connects with the deep main sewer in Gt. Charlotte
Street, was found to be a sound and good specimen of brickwork,
but in a foul condition, for want of flushing and cleansing; the
other sewer, which runs directly under the buildings .on the east
side of Marlborough Street, and over which the Board School is
built, is in a bad and defective condition.
The first mentioned sewer was cleared, and all defective
joints pointed up in cement; it was then extxtended, by means of
15 inch stoneware pipes, a further distance of 70 feet. A
connection was made from the old defective sewer to the new
sewer, and the direction of the drainage diverted. A new side
entrance was constructed and head walls built to disconnect the
old sewer ; it will now be necessary that all buildings draining
into the old sewer shall be disconnected, the sewer can then be
filled up and abolished.
High-level
Sewer from
Southwark
Bridge Road
to Park
Street.
This old high level brick sewer was in a very defective
condition, and although connected with a flushing pipe to the
river, could never be properly cleansed in consequence of certain
sections of the sewer having no invert. The wooden piles upon
which the walls were built having rotted away, the sides had
fallen in a number of places, and blocked up the bottom of the
