HOUSE DRAINAGE.
During the year the drains of twenty-three houses and premises
have been reconstructed. The work of reconstructing drains has
been carefully supervised, and frequent visits have been made to
the premises while such work was in progress. All drains and vent
pipes were subjected to the application of the water or air test
before being covered up.
The material used in the construction of new drains was chiefly
of stoneware pipes, but in several instances heavy cast iron pipes
were used.
Fifty gullies, 10 intercepting traps, 22 pedestal water closets,
4 soil pipes, 12 fresh air inlets, and 11 ventilation shafts were fixed
and 34 disconnecting and access chambers built.
Some trouble was again experienced in connection with combined
drainage, but I am pleased to report that satisfactory
negotiations were entered into with the owners, and the expenses of
legal proceedings avoided.
