3. The water supplied had no plumbo solvent action but
samples are tested for presence of metals.
4. No action has been required in respect of contamination
of the water. All water is chlorinated before distribution
and all new and repaired mains are chlorinated before being
restored to use.
5. With the exception of a very few outlying cottages, all
the houses in the area are supplied from the public water
mains. Only a very limited number of houses are supplied
by standpipes common to two or more houses, the vast
majority being supplied direct. Population supplied with
water from standpipes is approximately 25.

Conclusion
In conclusion I should like to thank the members of

during the year and also Mr. Bell and the staff of the
department for their able and willing assistance.
