Parkside School Swimming Bath
All samples were found to be satisfactory.
Dick Sheppard School
One sample was unsatisfactory due to a plant failure but the necessary
repairs were attended to.
St. Martin-in-the-Fields School
At the beginning of the year, a fault in the chlorinator developed. This
gave rise to an unsatisfactory sample. The plant was speedily repaired and
satisfactory conditions restored.
In general the bacterial conditions of the baths showed some improvement
compared with that of the previous year.
Plans were made for the organisation of special courses for schoolkeepers
and for Lido superintendents on swimming bath plant maintenance, on control
of dosage and on routine tests for free chlorine content and pH value. The
Scientific Branch and the Department of Mechanical and Electrical Services
collaborated in drawing up a training scheme involving lectures, visits, practical
demonstrations and discussions. These courses lasting two days were planned
to take place during the following year.
SEWERS
I am indebted to the Borough Engineer and Surveyor for supplying me
with the following information with regard to sewers within the Borough.
During the year a sum of £42,600 was spent on the general maintenance,
flushing and cleansing of the sewers for which the Council is the drainage
authority. Part of the cleansing works were carried out under contract using
high pressure jetting equipment and approximately 72 miles were cleansed by
this method.
Two contracts were completed for the reconstruction and laying of new
sewers
(a) Streatham High Road - Stage 1 at a cost of £11,280 which consisted
of laying a new 15" diameter sewer 155 yards long in Natal Road.
(b) Hawke Road - Stage 1 at a cost of £8,350 which consisted of laying of
110 yards of 21" diameter sewer and 65 yards of 18" diameter sewer
