The interceptor owner shall maintain records, including pumping date; condition of interceptor after pumping, including repairs needed; name, license number, and phone number of hauler, how much was pumped, where waste was disposed; phone number of waste disposal site; and a copy of original manifest from waste hauler, Documentation must be in a readily accessible location for Village personnel to inspect. Documentation must be retained for a period of no less than three years.
(c)

(d) 
The interceptor owner will be required to submit annual maintenance records to Village by January 31.
(e) 
Village personnel will perform periodic inspections of grease interceptors and will notify the facility of additional required maintenance or repairs. Upon written notification by Village, the facility shall be required to perform the maintenance and submit a remediation report to Village within 21 calendar days. Upon inspection by the Village, the facility may be required to install, at their expense, additional controls or provide a complete system that prevents discharges of undesirable materials into the wastewater collection system.

(i) 
Any grease interceptor owner found using chemical and/or biological additives to emulsify or remove grease will be fined no more than $100 for the first offense, $300 for the second offense, $1,000 for the third offense, and $2,000 thereafter per offense.
(j)

[Code 1966, § 23.13; Ord. No. 738, §§ I, II, 6-15-2004; amended 2-16-2022 by Ord. No. 1004]
(a) 
Computation of wastewater flow. The water consumption, as determined from the meter records of the Village water utility, shall be the basis for computing the wastewater flows, unless:
(1) 
The water is contained in a product or is evaporated or is discharged as unpolluted water or waste to surface drainage. In such cases, an application may be made for a reduction in the volume of wastewater discharged to the collection system, provided supporting data, satisfactory to the Utility Director, is furnished. This data shall include a flow diagram, destination of water and/or wastewater, supported by submetering data, installed on such process piping, at the expense of the user.
(2) 
The water is condensed from a product, so that the quantity of wastewater is increased over the amount of water being metered. In such cases, the increased flow shall be metered in a manner which is acceptable to the Utility Director and added to the flow obtained from the water meter readings.
(3) 
The quantity of water used during the third billing quarter at any single-family or duplex dwelling units producing domestic wastewater and having a lawn in connection therewith, shall exceed the quantity of water used during the second billing quarter of the calendar year. In such cases, the meter reading for the second billing quarter shall be used in determining the wastewater flow for such third billing quarter; provided, however, that this section shall not be applied to any premises where the water service was disconnected at any time during the second billing quarter. The second billing quarter shall be defined as the months of April, May and June.
(4) 
When water for sprinkling lawns or filling swimming pools is metered separately, no user charge will be made. All such metering shall be at the user's expense.
(5) 
Any lot, parcel of land, building or premises discharging domestic wastewater or industrial waste into the collection system, which is supplied in whole or in part with water not obtained from the water utility, the owner or occupant of such property shall cause to be installed necessary metering equipment as approved by the Utility Director to measure the quantity of water pumped or discharged to the collection system. The user charge shall be based on the quantity of water so measured. Whenever the person fails to install such metering equipment, or where it is not practicable to measure the water consumed on any premises by a meter or meters, the Utility Director shall determine the estimated volume of water discharged into the wastewater works.
(b) 
Metering devices. The Utility Director may require the installation of devices for metering the volume of waste discharged if those volumes cannot otherwise be determined from metered water consumption records or if flows from the sewer user are deemed by the Utility Director to require flow metering devices. The metering devices shall be owned and maintained by the person and may not be removed without consent of the Utility Director.
(c) 
Control manholes. All persons discharging industrial wastes into the wastewater works shall construct and maintain sampling manholes in suitable and accessible locations on public property or easement to facilitate the observation, measurement and sampling of all his wastes or wastewater. Sampling manholes shall be located and constructed in a manner approved by the Utility Director. Plans shall be submitted to the Utility Director prior to construction.
(d) 
Sampling manholes. In the event the wastewater Utility Director determines that a commercial property has or is likely to discharge commercial wastes into the wastewater works in amounts or of a quality that would make it beneficial for the wastewater works to have a sampling manhole installed, then the property owner shall construct and maintain sampling manholes in suitable and accessible locations on public property or easement to facilitate the observation, measurement and sampling of all his wastes or wastewater. Sampling manholes shall be located and constructed in a manner approved by the Utility Director. Plans shall be submitted to the Utility Director prior to construction.
[Code 1966, § 23.14; amended 2-16-2022 by Ord. No. 1004]
(a) 
The Village will collect samples and perform laboratory tests on industrial waste discharges as necessary to verify the quantity of flow and character and concentration of an industrial waste. The utility test results shall be used to determine the applicable surcharge.
(b) 
Waste or wastewater discharge may be sampled manually or by the use of mechanical equipment, as necessary, to obtain a representative twenty-four-hour composite sample. Samples shall be taken at intervals to be established by contractual agreement under § 86-278 or at such intervals as determined by the Utility Director.
(c) 
When Wis. Adm. Code § NR 101 or NR 202 require the submittal of the character, and concentration of wastes, waste volume, and production information to the utility or state department of natural resources (DNR), the user shall have the waste character and concentration determined by an independent testing laboratory. A copy of the test results and DNR reports shall be submitted to the Utility Director.
(d) 
All measurements, test analysis of the characteristics of industrial wastes shall be determined in accordance with Chapter NR 219 of the Wisconsin Administrative Code.
