SECTION III.
SANITARY CIRCUMSTANCES OF THE AREA.
1. Water Supply.—The water supply of Chiswick
is a constant one, and is derived from the mains of the
Metropolitan Water Board. The excellent quality of the
water is too well-known to need comment, and naturally no
complaints as to its purity have been received. A large
majority of the houses are fitted with a direct supply from
the rising main, and certainly, practically all the houses
which are from time to time scheduled for house-to-house
inspection are so supplied. The houses have, of course,
storage cisterns for emergency supplies, and the flushing of
the sanitary conveniences as required by the Metropolitan
Water Board Acts. Particulars of the number of draw taps
placed on mains for a direct supply of water will be found in
the special tabular statement relating to the sanitary work
of the Department.
2. River Pollution.—Complaints have from time to
time been received from the Port of London Authority
respecting the pollution of the River Thames, as proved by
the analysis of samples taken from the outfall of the surface
water sewers. These complaints have been fully investigated,
and practically the whole of the drainage in the Chiswick
Park and Old Chiswick Wards has been examined with a
view to preventing possible pollution of the surface water
sewers. The laying of new surface water sewers throughout
the length of both Devonshire Road and Chiswick Eane has
largely mitigated the possibility of such pollution in the
future.
3. Drainage and Sewerage and Sewage Disposal.—
The District as a whole is efficiently drained and sewered—
for the most part on the dual or separate system. The
extension of the system of separate surface water sewers
leading direct to the River, and the relaying of existing sewers,
while assisting in reducing the quantity of sewage to be
treated at the Disposal Works during rainy periods, has also
