that the work of lowering the pipes has commenced,
but at present it is only in about 10 roads
that the lowering of the mains has been completed.
DRAINAGE AND SEWERAGE.
At the end of the year the sewerage of private
roads was completed, and some house-holders in
those roads have connected their houses. The
system worked well during the year, and I hope
with a greater number of connected houses, the
flushing of the sewers will be effected without the
help of water supplied by carts, as more effectual
flushing will minimize the smells from the manholes,
which still cause numerous complaints. In
some places more ventilating shafts will probably
be necessary. The system at the Sewage Disposal
Works answers very well, only one complaint of an
offensive smell has been received during the year.
In August the Thames Conservancy Inspector
pronounced the effluent unsatisfactory. The
Council instructed the Surveyor to arrange that
the effluent from the precipitation tanks should be
more regularly and evenly distributed over the
purification area, and this has been done with
satisfactory results. With this exception, the
Thames Conservancy Inspector who visits the
works very frequently, has pronounced the effluent
to be satisfactory.
In reference to house drainage, the Council
took a very important step, with a view to ensure
efficient drainage in the future by passing a resolution
to the effect that the drains of all new houses
shall be submitted to the dydraulic test before
being passed by the Council's Surveyor.
