In the reduction of the 1905—1914 mean Annual
Rate of 76 to 1915—1919 one of 61, it will be observed
that the proportion of deaths under one month to the
total deaths has risen from a little more than one-third
to a little less than one-half.
WATER SUPPLY.
The Sutton District Water Company's Works are
situated about midway between the northern and
southern borders of the district, on the east
(Carshalton) side of the High Street. Deep wells are
sunk in the chalk a little above the site where the
London tertiaries outcrop. The Company is required
by Act of Parliament (1903) to soften the water to not
less than 9 degrees of hardness, and it has been found
by frequent analyses made at the Health Office that
this standard was rarely exceeded.
The supply is constant.
Chemical and bacteriological examinations of the
water show it to be a good drinking water.
RIVERS' AND STREAMS.
A very small stream, called the Pyl Brook, receives
nearly all the surface water of the district. Into it is
discharged the outflow from the sewage works. This
brook discharges unto the Beverley Brook, and that into
the Thames. The Port of London Authority makes
frequent examination at the sewage outflow, and no
complaint has been received during the year. The
remainder of the surface water drains into a much
smaller channel, which joins the River Wandle.
DRAINAGE AND SEWERAGE.
The district is sewered except in the outlying rural
and sparsely populated parts on the clay, where cesspools
are still in use and emptied from time to time by
the Health Department.
The Council have under consideration a scheme of
extension, including the sewering of the London Road
(Stonecot Hill). The proposed development of an
estate on the west side of London Road (Rose Hill)
