SECTION C
SANITARY CIRCUMSTANCES.
1. WATER SUPPLY.
The town'a water supply is provided by the Metropolitan
Water Board who maintain constant supervision over
the purity and adequacy of the supply.
Well water is used for industrial purposes at certain
factories in the town.
2. DRAINAGE AND SEWERAGE*
The position regarding disposal of sewage remains the
same as for last year. naraely that the sewage from the
Borough is pumped across the river into a sewer in the
Teddington area9 for treatment at the Mogden Disposal Works
of the West Middlesex Main Drainage Boardu This arrangement
is a temporary one pending completion of the Hogsmill Valley
Joint Sewerage Board's works which is now in course of construction®
3* RIVERS AND STREAMS®
The River Thames forms the Western boundary of the
Borough and this river is under the control of the Thames
Conservancy Board.. The Hogsmill River. a tributary of the
Thames flows through the Borough® The chemical and
bacteriological condition of the stream is very unsatisfactory.
This is due to lack of natural dilution for the
sewage effluent carried in its flow.
In the 1953 Report reference was made to investigations
in respect of the entry of foul water into a surface
water sewer which discharged into the Hogsmill Rivered
Testsp by the use of tracing materials. were carried
out to the drainage systems of ninety-five houses thought
to have connections to this sewer. In one instance the
W.CS. of the house were found to be discharging into the
surface water sewer and in a further ten cases sinks baths
and wash basins had been wrongly connected to the surface
water system.
In all the cases referred to above. after due notice9
the fittings were properly discharged into the foul water
sewer.
The above emphasises the need for due notice to be
given to the Department of intention to connect sanitary
fittings to drainage systems®
U. CLOSET ACCOMMODATION.
All closets in connection with dwelling houses in the
Borough are on the water carriage system®
