Columbia Private source inflow and infiltration reduction program ordinance (§ 22-217.3)

In order to reduce instances of surcharged sanitary sewers due to inflow and infiltration, which are inimical to public health and welfare, and reduce the frequency of sanitary sewer backups and sanitary sewer overflows to the environment, a cost reimbursement program for the removal of inflow and infiltration sources on private properties, is hereby established and authorized in accordance with the following:

(1) Subject to funds available in the annual budget, the city may reimburse a property owner up to the maximum city reimbursement listed on the following Table 1 or one hundred (100) percent of the cost, whichever is less, for the removal of improper inflow and infiltration sources on the property per program requirements. Improper inflow and infiltration means the entry of any unauthorized groundwater, stormwater or unpolluted water into the sanitary sewer system. All installations must meet current building codes as set out in chapter 6 of this Code.

Buildings connected to sewer mains owned by the Boone County Regional Sewer District or any customer of the Boone County Regional Sewer District connected directly to the city's public sewer

main are not eligible for reimbursement through this program. The director of utilities may deny any application where it is determined that improper inflow and infiltration are likely not occurring or there is minimal impact on the public sewer system.

(3) This program shall apply only to applications after December 4, 2017, and where approved for reimbursement through this program prior to the work being completed. The city shall, in its sole discretion, determine the eligibility for participation in this program.

(4) Financial participation of the city in this cost reimbursement program is limited to funds budgeted for the program. Funding levels may be changed or eliminated based on the city's annual review of the program.

(5) The cost reimbursement program is limited to the actual cost of the installation of such items, subject to the funding limitations described herein, but does not include incidental or ancillary costs such as, but not limited to, landscape restoration, painting, tile, carpeting, etc.

(6) The property owner must allow the city to inspect the property owner's building prior to the city's determination of eligibility for this program. All sources and potential sources of infiltration and inflow, deemed significant by the director, must be eliminated as part of this program. The property owner must allow the city to inspect the building following participation in the program and completion of the installation to ensure that all infiltration and inflow into the city's sanitary sewer system has been eliminated. All costs and expenses submitted for reimbursement are subject to review and audit by the city.

(7) The director of utilities is authorized to develop program requirements, application forms, participation agreements and such other documents necessary to implement this cost reimbursement program.

(11) The city manager is authorized to execute agreements for participation in this cost reimbursement program.
