During the year 1,560 yards of 4" diameter main and 732 yards
of 6" diameter main were laid in the borough.
The General Manager and Engineer-in-Chief of the Essex Water
Company has furnished the following report:-
"Bacteriological and chemical examinations are made of the raw
water, of the water in its various stages of treatment, and the water
going into supply. A total exceeding 10,000 chemical, bacteriological
and biological examinations have been made and all water going into
supply was wholesome. Analyses have also been made of samples obtained
from consumers' taps in the various parts of the Company's district,
including that of your Council and all proved to be satisfactory."
SEWERAGE AND SEWAGE DISPOSAL
I am indebted to the Borough Engineer and Surveyor who has supplied
the following information:-
"The drainage systems of the borough function adequately,
although infiltration at times of high intensity storms causes
difficulties in isolated instances. Improvements to the Dagenham
trunk foul systems are at present under construction and progressive
improvement can be expected as the work proceeds with completion of
the contract anticipated in the autumn of this year. Allied with the
recent completion of the Riverside Sewage Works the foul drainage
system for the Eastern sector of the borough will cater for present
flows and will contain some spare capacity for future requirements.
Drainage improvements in the Western section of the borough are
concentrated in the Barking Central Area. Work is progressing on the
detailed design with implementation anticipated in 1972, giving relief
to both surface water and soil systems and incorporating a new pumping
station and outfall into the River Roding."
SWIMMING BATOS
There are three open air and one indoor public swimming pools
in the borough. In addition there is a pool at the North East London
Polytechnic Barking Precinct and four of the schools are provided
with small pools. All swimming pools take their water from the mains
of the Essex Water Company.
Regular samples have been taken during the year and all results
were satisfactory with the exception of one taken from an open air
pool. The organic quality of this sample was of high standard but the
bacterial impurity included Bact. coli in appreciable numbers.
Investigations were carried out and another sample taken; this proved
to be satisfactory. There has been no further trouble in this respect.
