Disposal of House Refuse.
The Council contract for a weekly removal of all house
refuse. The refuse is burnt in the open on the Sewage Farm.
A small charge, based on the estimated cost of removal, is
made for the removal of trade refuse.
Analyses Performed during the Year.
The samples examined during the year included :
A sample of the public water supply taken each month.
The samples were drawn from standpipes in various parts of
the District, and on chemical analysis were found to conform
in each instance to a high standard of organic purity.
During the Summer and Autumn several complaints were
received on account of the cloudy appearance of the water
when freshly drawn. In the samples examined the cloudiness
was due to the presence of carbonate of lime in suspension,
and there was no excess of organic matter.
Analyses were also made of 16 samples of sewage effluent,
several samples from Dollis Brook and various shallow wells,
and samples of mortar.
The samples of effluent were generally satisfactory, but
on three occasions the percentage of incompletely purified
organic matter was above the normal.
Notes upon Sanitary Work performed during the Year.

out, including visits to the dairies, cowsheds, slaughterhouses,
bakehouses, workshops, houses in which epidemic disease had
broken out, insanitary property, and routine house to house
inspection. In all, some 5,839 inspections were made, and
nuisances to the number of 1,476 were discovered.
