WATER SUPPLY.
Friern Barnet's water supply is provided by the
Lee Valley Water Company, except for a small part of the
South Ward which is supplied from the mains of the
Metropolitan Water Board.
All the houses in the district have an internal
supply.
The supply has been adequate and no complaints
were received concerning its quality. The reports on
samples shewed that it was of a high standard of bacterial
purity and suitable for public supply purposes.
The water is hard and has no plumbo-solvent action.
PEST CONTROL.
Complaints relating to rats or mice received
during the year totalled one hundred and twenty-six. The
actual number of rat infestations found in investigating these
complaints and during other routine inspections throughout
the district was seventy-nine. These figures are similar
to those recorded last year and, accepted as an indication of
the extent of rat infestation, are encouraging, since they are
considerably lower than at any previous time.
The treatments to clear up infestation at private
dwellings are carried out without charge to the occupiers, but
where business premises are involved a charge based on the
labour ana material used is made.
Two treatments of the district sewers were undertaken,
a routine control measure followed since 1947. The results
of these treatments suggested that the level of infestation
in the sewers had risen very slightly.
The number of premises cleared of mice during the
year was twenty.
There were a number of requests for advice and
aid to deal with various insect pests, the most numerous being
in respect of wasps nests, of which eighty-four were destroyed.
