Cleansing of
Public Sewers
and Drains
The cleansing and unblocking of choked sewers and drains
has continued to be carried out by three manual staff of the
Health and Welfare department.
Whilst most of this work is done during normal working
hours, I feel that praise is due to the men involved for their
willingness to turn out during ever???ings and week-ends to deal
with emergencies. The abatement of nuisances such as over
flowing drains is always considered an urgent matter, and as
stated in my last report, residents have expressed their appreciation
of the promptness and efficient manner in which this
work Is carried out. Altogether 1,514 blockages were dealt with
during the year.
Another service operated by the department is the testing of
drains on request and payment of a fee based on a percentage
of the gross rateable value of the property. This is very useful
for a resident with doubts on the drainage systems of his house,
and for prospective purchasers. It is limited by the availability
of means for testing, i.e. inspection chambers, and no excavations
are carried out.
