WHEREAS, based on the recent history of actual sewer system overflows and the estimated flow of clear groundwater to the city's sanitary sewer system originating in each of its sewer basins, the availability of city resources to reduce such flows under the city's I&I program and the results anticipated from so allocating such resources, the director of public works and utilities has recommended that sewer basins 1, 2, 3, 4 and 5 be designated for inspection as provided for in Section 43-33 of the Code; and

WHEREAS, the council accepts said recommendation.

RESOLVED, that pursuant to the provisions of Section 43-33 of the Code, sanitary sewer basins 1, 2, 3, 4 and 5 are hereby designated as the districts in the city wherein the city can best utilize its available resources to reduce the amount of unpolluted water entering or infiltrating the city's wastewater collection system and said basins are therefore designated as districts within which the city shall focus its enforcement efforts under Chapter 43 of the Code.

FURTHER RESOLVED, that the director of public works and utilities is hereby directed to notify, in writing, the owners and persons in control of premises connected with the sanitary sewer within such districts to disconnect any prohibited drain or device within 90 days after the date of such notice in the manner prescribed for such notices in said Section 43-33.

STATEMENT OF PURPOSE:  The purpose of this resolution is to designate the city's sanitary sewer basins 1, 2, 3, 4 and 5 for focused enforcement of the city's I&I reduction program efforts. These basins, located substantially in the Lakeside and Lester Park neighborhoods, are depicted on the maps filed with this resolution and are provided to councilors.

Section 43-33 of the City Code calls for the council to designate the sanitary sewer basins in which the city can best utilize its resources to reduce the I&I problems after recommendation from the director of public works and utilities. Districts 1 through 5 are the districts in which the city has already been focusing its efforts under the prior I&I reduction program, but staff estimates that approximately 280 households in these basins have not permitted inspections of their sanitary sewer systems and therefore may not be in compliance. In addition, these sewer basins are known to be large contributors to the I&I problem and the only way of dealing with the problem that I&I is causing in these neighborhoods, other than elimination of I&I at its source, is to construct huge, underground, temporary storage tanks to temporarily hold, and then slowly release, the large influx of mixed sewage and clear water infiltrate resulting from heavy rainstorms; the cost of such storage will be very high and would have to be born by the rate payers. Any reduction of clear water inflow into the system will reduce proportionately the size, and therefore the cost, of constructing such temporary storage.

Based on this situation, the director has recommended that the city continue to focus its efforts in these basins, implementing the new I&I program's mandatory compliance requirements.

As provided for in the ordinance, notice will be sent to all affected property owners informing them of the requirements of the ordinance and of the assistance available from the city to bring their properties into compliance.
