Each unit of completed supply line distribution
system shall be sterilized with chlorine before acceptance for domestic
operation. Sterilization shall be accomplished as described below
or by the system prescribed by AWWA C 601 as determined by the Town
Inspector. The amount of chlorine applied shall be such as to provide
a dosage of not less than 50 parts per million. The chlorinating material
shall be introduced to waterlines and distribution systems in a manner
approved by the Town Inspector. If possible to do so, the lines shall
be thoroughly flushed before introduction of the chlorinating materials.
After a contact period of not less than eight and preferably 24 hours,
the system shall be flushed with clean water until the residual chlorine
content is not greater than 1.0 part per million. All valves in the
lines being sterilized shall be opened and closed several times during
the contact period. After flushing, samples of water shall be taken
from each section of main and an analysis made to determine the purity
of the water. Any section of main not meeting the standard for purity
shall be re-chlorinated and tested until acceptable. The results of
the tests shall be given to the Town Inspector. All costs for water
tests will be paid for by the subscriber.
Booster pumping stations, storage facilities
and other appurtenances to the distribution system shall be designed
and constructed to afford a maximum of dependability and efficiency
in operation and maintenance. Two copies of as-built drawings of these
facilities, together with all manuals and descriptive data, shall
be furnished to the Town Clerk before the facilities will be accepted
by the Town.
