Unpolluted water including but not limited to cooling water, process water or blow-down from cooling towers or evaporative coolers shall not be discharged through direct or indirect connection to a city sewer unless a permit is issued. The city may approve the discharge of such only when no reasonable alternative is available.

If a permit is granted for the discharge of such water into a community sewer, the user shall pay the applicable charges and fees and shall meet such other conditions as required by the city. (Ord. 2282 NCS §3 (part), 2007.)
