§ 470-4 Use of public sewers.

A. 
All industrial users discharging industrial waste water to the sewerage system shall install a control manhole in accordance with Ch. COMM 82 Wis. Adm. Code. The control manhole shall be installed at the most representative location of the waste water flow for the industrial user. The control manhole shall be installed and maintained by the industrial user at the user's expense. The control manhole shall be maintained by the industrial user so as to be safe and accessible at all times. The industrial user may be required to install temporary or permanent flow sampling and metering equipment at the discretion of the City. If so required, the cost for installation, operation, and maintenance of such equipment will be at the expense of the industrial user.
B. 
All significant industrial users discharging industrial waste water to the sewerage system shall install a control manhole in accordance with Ch. COMM 82 Wis. Adm. Code. The control manhole shall be installed at the most representative location of the waste water flow for the significant industrial user. The control manhole shall consist of a manhole on the industrial users discharge line with a volume measuring device and a separate structure housing volume recording instruments and an automatic proportional sampler. The sampler shall automatically (in proportion to the discharge volume) collect samples of the waste water. The control manhole structure, volume measuring devices, and waste sampling devices, shall be approved by the DNR and the City prior to installation. The significant industrial user shall install, operate, and maintain the control manhole, metering facilities, and sampling facilities at its own expense. The significant industrial user shall record volume at its own expense. The significant industrial user shall record, sample, test, and analyze waste water flow and character atits own expense. The City shall determine the level of waste water analysis, including the frequency thereof, which will be required for each significant industrial user on a case by case basis. Sample collection, preservation, and analysis shall be in accordance with Chs. NR 218 and NR 219 Wis. Adm. Code. The significant industrial user shall grant access to the City to the control manhole, and all associated metering and sampling equipment, at all times.
C. 
Service agreements. In the event an industrial user discharges industrial wastewater constituting a substantial portion of either the design flow capacity or the BODS, TSS, or phosphorus capacity of the sewage treatment facility, as defined in the Compliance Maintenance Report (CMAR) filed by the city with the DNR, then a service agreement between the industrial user and the city shall be executed. Service agreements shall be required when an industrial user discharges industrial wastewater that comprises 10% or more of the average day design flow, or 10% or more of the average daily design BODS, TSS, or total phosphorus load for the sewage treatment facility. The service agreement shall assure continued participation in capital recovery by the industrial user over the life of the agreement. Should the industrial user eliminate its discharge, the City at its option may elect to assign to another user that portion of the design capacity of the sewage treatment facility and associated capital costs thereby relieving the industrial user of continued financial participation.
D. 
Sanitary sewers. No person(s) shall discharge or cause to be discharged any unpolluted waters such as stormwater, groundwater, roof runoff, subsurface drainage, or cooling water to any sanitary sewer.
E. 
Storm sewers. Stormwater and all other unpolluted water shall be discharged to such sewers as are specifically designated as combined sewers or storm sewers, or to a natural outlet approved by the Director and other regulatory agencies. Unpolluted industrial cooling water or process water may be discharged, on approval of the Director and other regulatory agencies, to a storm sewer, combined sewer, or natural outlet.
F. 
Prohibitions and limitations. Except as hereinafter provided, no person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewer:
