SEWER—MARDALE STREET.
It has been necessary to consider the question
of providing a new sewer to receive the drainage of
the Baths and Wash-houses in Lime Grove. The
Borough Surveyor submitted the following report
upon the question:—
"I have considered the question of the sewer outlet from
the new Baths and Wash-houses, and have prepared plan and
section shewing the levels.
The level of the inverts of the sewers above Ordnance
datum are:—Lime Grove 11.72; Mardale Street 9.28; the
water level of the Baths 18.50, the bottom of the Baths 12.25,
and the level of the lowest basement in Mardale Street is 13.08.
It would therefore be possible to connect the outlets from the
Baths with the sewer in Mardale Street, but for the liability to
flood the basements of the houses during the emptying of the
Baths. In addition, the sewers in Mardale Street and Lime
Grove are both 12in. in diameter, and a larger outlet sewer is
required to allow of the proper emptying of the Baths.
It has therefore been found necessary to construct a new
18 in. stone-ware pipe sewer down Mardale Street and connect
it direct into the main sewer in Goldhawk Road, and to
continue it westwards along Scotts Road for a distance of
about 100 feet in order to drain the second-class bath.
The outlet from the baths is connected to the sewer by
means of tumbling bays, to reduce the pressure of the water as
much as possible. The gradient of the sewer is 1 in 350.
The connection to the Goldhawk Road sewer is by means
of a bell mouth and manhole.
The total estimated cost is £850."
The work is now in progress.
