The mission of the Fox Metro Engineering Department is to improve the efficiency of the department by developing and exchanging ideas, information and technology which enhance the delivery of public services; and by promoting the personal and professional growth of its staff members.

One of the major responsibilities of the Engineering Department is to coordinate proper connections to and extensions of the collection (sewer) system which conveys sewage to the wastewater treatment plant. This is done as follows.

The Engineering Department provides developers with information and guidance regarding possible connection points, costs, and requirements of obtaining Fox Metro’s wastewater treatment services. Once a possible connection point from the proposed development to the collection system is selected, the Engineering Department prepares a draft annexation agreement for the development to be included in Fox Metro’s corporate boundary and service area.

The Engineering Department then provides the Developer with guidance in the preparation of various IEPA and Fox Metro permit applications and required plans. The Developer then submits a set of building and/or street sewer plans, depending upon the project type, for review by the Engineering Department. If the Engineering Department approves the permit application and plans, it then uses a standard rate schedule to determine and collect permitting and connection fees. The standard fee schedule helps ensure that each development pays its fair share for the capacity of the treatment plant that it will use.

Once the Engineering Department has issued a permit, the Developer must use a bonded contractor to construct the sewer service connection. The Engineering Department schedules periodic inspection of the construction to help ensure that Fox Metro specifications are being met. The Engineering Department does not allow newly completed sewers to be used until after they have passed various testing procedures. An internal television camera inspection is then done after all testing.

What do Fox Metro’s fees pay for?

• Annexation Fees: Pays for the proportionate share of operations, maintenance and rehabilitation of the existing collection system such as investigatory sewer televising, pipe lining, grouting of manholes, and excavation for repairs to reduce infiltration and inflow in the existing collection system.

• Infrastructure Fees: The fair share cost to construct, not only new manholes and interceptor sewers 15” & inches and larger, including new pump stations and new forcemains.  Also, as service areas expand, Infrastructure Fees also pay for the inevitable & perpetual replacement and eventual upsizing of same manholes, chambers, interceptors, pump stations, siphons, and forcemains.

• Connection Fees: As new sewage discharges from buildings, fixtures, and equipment consume a proportionate share of the treatment plant’s capacity, these fees finance the eventual costs associated with expansion of the daily volume of wastewater the plant can treat, including paying for unfunded mandates for plant improvements such as phosphorus removal, etc.

• User Fees: Operation, repairs, overhead, debt service, and chemicals for perpetual preservation and maintenance of the treatment plant works.
