The following regulations shall apply to all
water-cooled equipment installed for the purpose of reducing the dry
bulb temperature or decreasing the absolute humidity of air, whether
for comfort air conditioning, refrigeration, processing or whatever
other purposes.
No person shall install, operate or use any
equipment for air conditioning or refrigeration which requires a supply
of water from the system of the City of Ithaca without first having
procured a written permit therefor from the office of the Water and
Sewer Division.
All installations shall be made in conformance
with the Plumbing Code and subject to the inspection of the Plumbing
Inspector and will include the following general protective measures:

wastewaters shall be in accordance with the Plumbing Code and Board of Public Works regulations regarding sanitary
sewers.

from the Plumbing Inspector approving the proposed connections and
use.
D. On installations other than those described above,
there shall be a physical break between the public water supply piping
and the piping of the installation, so arranged as to make backsiphonage
to the public water supply system impossible.

to operate or use equipment may be revoked by the Water and Sewer
Division for any one of the following reasons:

using water for the purposes covered by the permit immediately upon
notice to do so issued by the Water and Sewer Division during an emergency
or to forestall an impending emergency.

operation or lack of maintenance which results in conditions that:
