1. Lift station means a sewer pumping facility greater than three horsepower or serving more than one residential or commercial unit that takes the place of the gravity flow sewer system.
2. Force main means a principal conduit through which water is pumped as distinguished from one through which it flows by gravity.
3. Gravity flow sewer means the part of the wastewater system that uses gravity, as opposed to lift stations, pumps, or pressure lines, to transport sewage.
4. Sewage means any liquid or water-carried industrial or sanitary wastes, whether treated or untreated, including polluted heating and/or cooling water from dwellings, commercial buildings, industrial facilities and institutions, that is contributed or permitted to enter the public sewer system.
5. Sewer means a pipe or conduit that collects and carries wastewater.
6. Ejector pump means a mechanical unit through which sewage is lifted to an elevation where gravity flow sewer is available.

1. Lift stations will be permitted only when gravity sewer to the property being served is unobtainable, as determined by the public works director upon recommendation of the city engineer and as approved by the city council.
2. No lift stations and/or force main shall be permitted where installation is not incompliance with the City's Sanitary Sewer Master Plan.
3. Lift stations shall not be allowed as part of any development or real property in American Fork, regardless of the number of units or type of development being constructed or other constraints including offsite improvements, without the city's expressed written approval granted by the city council. The director of public works, in coordination with the city engineer, shall review all proposed lift stations and provide his/her recommendation to the city council for its consideration prior to approval of any submittal.
4. In the event a private lift station and/or force main is permitted on private property, the lift station shall not be dedicated to the city and will not be owned, maintained, or operated by the city.
5. No lift stations or force mains shall be permitted in the public right of way or public easement, including public utility easements.
6. In the event a private lift station is permitted, any and all damages resulting from said lift station, including, but not limited to, overflows, spills, and backflows, are the responsibility of the owner/applicant. Overflows, spills and backflows shall be subject to fines, penalties or regulatory enforcement by the city.

1. All lift stations and connecting infrastructure shall be private. If a private lift station is approved by city council, all drainage/flow to the lift station shall result from private infrastructure. No public infrastructure shall supply sewage either to or from a private lift station.
2. All connections into the city's public infrastructure shall occur through a privately owned gravity flow sewer.
3. All lift stations shall be below grade with no less than duplex submersible pumps operating in a lead-lag configuration such that the pumps alternate after each pump cycle.
4. Each lift station shall have an above-grade access hatch of a size, configuration, and elevation that is readily accessible for a human being and suitable for easy installation and removal of the pumps. The hatch shall be designed and located such that surface water flow cannot enter the lift station.
5. All pumps shall be able to pass a three-inch diameter solid.
6. The lift stations shall be made of fiberglass, or other material approved by the city engineer.

1. The owner/applicant shall furnish and install the entire lift station/force main system. The system shall be designed, at the sole cost and expense of the owner/applicant, by an engineer licensed in the State of Utah. The design must be reviewed and approved by the city engineer. The designer shall consult with the city engineer during the design of the system.
2. Development and design plans shall provide the following:
   1. Connection to the city's infrastructure through a privately-owned gravity flow sewer line;
   2. Design calculations, including pump curves, showing the pump and system head curves;
   3. Private infrastructure plan, including delineation of the basin and sub-basins that drains to the lift station, along with contours and projected flow calculations;
   4. Details of the lift station installation including grades, materials of construction, control systems, etc.;
   5. Plan and profile views;
   6. Electrical supply and control diagrams showing all electrical requirements, as well as control logic diagram (or a written description of the control logic);
   7. Site plan showing finished grade contour lines (two-foot intervals) in and around lift station and access road and all existing and proposed utilities; and
   8. Any other specifications and details reasonably required by the city engineer.

(Ord. No. 2018-03-10, 3-13-2018)

1. Lift stations shall have the following:
   1. Fenced area eight-foot-high fabric nine-gauge wire (chain-link type) with top rails and bottom tension wires; three strands barbed wire at top on angled extension arms; posts embedded in a minimum of three-feet of concrete; posts are to be spaced a maximum of ten feet apart;
   2. Fourteen-foot wide gate on four-inch diameter posts;
   3. High pressure sodium security light on twenty-foot pressure treated pole with automatic eye;
   4. The wetwell shall be sized to prevent excessive cycling of the pumps.
   5. Hatch doors shall be sized by the pump supplier to allow adequate clearance to easily remove the pumps;
   6. The force main must have a cutoff valve positioned after the check valve pit.
   7. No conduit runs or junction boxes are to be installed inside or on top of wet well.
   8. Lift stations shall have factory-installed hour meters to show pump's running times to the tenth of an hour.

(Ord. No. 2018-03-10, 3-13-2018)

1. Lift stations shall be operated under the direction of a certified Wastewater Collection Systems Operator Grade II or higher. The current name and contact information of the systems operator acting as the direct responsible charge shall be on file with the city, and shall be accessible at all times. The lift station and/ or force main shall be inspected by a qualified contractor no less than quarterly. Based upon system design and capacity, more frequent inspections may be required.
2. A record of all inspections shall be maintained.
3. All inspection records and logs shall be provided to the city upon request and no later than December 31 of each year.
