WATER SUPPLY
I am indebted to Dr. E. Windle Taylor, Director of Water
Examination of the Metropolitan Water Board, for the following
information.
The supply for Hornsey area has been satisfactory both in
quantity and quality during the year. The area is supplied from
two main sources:-
(a) River Thames derived water via Ashford Common works
and Fortis Green pumping stations.
(b) New River water (River Lea and well water) via Stoke
Newington and Hornsey filtration stations.
The water supply is in all cases direct to dwelling-houses;
none is supplied by means of a stand-pipe. The water supplied to
this area is not plumbo-solvent.
No new sources of supply have been instituted and there have
been no important extensions of trunk mains nor changes in the general
scheme of supply to the Borough.
Details of the analytical results of the water passing into
supply are shown below.
