New and existing building sewers may be periodically monitored by the city for leaks or discharges of extraneous water.

This monitoring may take the form of, but is not limited to: direct visual observations; indirect measurements; television inspection; or air or water pressure tests, smoke tests, or exfiltration tests.

If, in the opinion of the Director, such monitoring shows a building sewer to be defective, no further proof is needed for the Director to require the building sewer be repaired to current standards at the owner’s expense.

Existing building sewers that exceed a maximum allowable infiltration/inflow rate of more than 300 gallons per day per single detached living unit; 1,200 gallons per acre per day; or 3,000 gallons per day per inch-diameter miles of sewer are deemed unsafe and unsanitary and shall be repaired at the owner’s expense.

Those sewer users who do not comply with the infiltration/inflow regulations shall have a period of time as determined by the Director, to reach compliance with the regulations. (Ord. 4987, 2015).
