D. Whenever any person desires to make or maintain any connection with any part of the public sewer for the purpose of discharging sewage or waste which contains any of the objectionable substances, the person shall apply to the director for a permit for those purposes.

The permit shall be issued only upon payment to the director of a fee as set by the city council and shall expire one year after the date of its issuance.

1. The permit shall be revocable whenever it appears to the director that the holder thereof has violated any provision of this chapter or when the intercepting appliance does not prevent the objectionable substance or substances from entering the public sewer.

(Ord. No. 1292, § 1, 6-24-09)

If an existing plumbing outlet or fixture has been installed or located or if a plumbing outlet or fixture is to be installed or located at an elevation which, in the opinion of the director, may cause the fixture to overflow by reason of backflow from a main-line sewer, an approved type of backwater trap or sewer valve shall be installed between the outlet and the public sewer in such manner as to prevent sewage from flowing back or backing up into the outlet or plumbing fixture. The trap or valve shall be installed in the basement or in a box or manhole of concrete or cast iron or other material approved by the director and shall be readily accessible at all times. The trap or valve shall be placed only in the drain serving the outlet or fixture that may be subject to overflow and no sewage from outlet or fixtures not subject to overflow shall pass through the trap or valve. If the property owner fails to install and maintain a backwater trap or valve in good working condition when required to do so by the director, the director may order and require the plumbing fixture to be disconnected and removed and the plumbing outlet be plugged or capped.
