Any person responsible for discharges through a building sewer carrying industrial or non-domestic wastes shall at his own expense and as required by the city:
(1) 
Install an accessible and safely located control manhole as required in section 13.07.179;
(2) 
Install meters, sample ports and other appurtenances to facilitate observation, sampling, and measurement of the waste and flows discharging into the POTW as specified in divisions 5 and 6 of this article; and
(3) 
Maintain the equipment and facilities.
(Ordinance 5523, sec. 1, adopted 11/3/08)
When discharges of industrial or non-domestic waste are approved by the city, the city or its representative shall enter into an agreement or arrangement providing:
(1) 
Terms of acceptance by the city; and
(2) 
Payment by the person making the discharge.
(Ordinance 5523, sec. 1, adopted 11/3/08)
(a) 
Any person discharging or desiring to discharge an industrial or non-domestic waste mixture into the sewers or POTW of the city, or any sewer connected therewith, shall provide and maintain in a suitable accessible position on the premises, or such premises occupied by the person, an inspection chamber, or manhole, near the outlet of each sewer, drain, pipe, channel, or connection which communicates with any sewer or POTW of the city, or any sewer connected therewith.
(b) 
Plans for the construction of control manholes or inspection chamber, including such flow measuring devices as may be hereinafter required, shall be approved by the city manager prior to the beginning of construction.
(Ordinance 6459 adopted 2/21/22)
(a) 
When the public water supply is used exclusively, the water consumption during the previous month, as determined from the meter records of the water department, shall be the valid basis for computing sewage flow, unless actual sewage flow is measured by a recording meter of a type to be approved by the city manager. The owner shall maintain such device in proper condition to accurately measure such flow. Upon failure to do so, the water consumption shall be the basis for charges.
(b) 
In cases where all or part of the water consumed is obtained from private supplies, wells, etc., such persons shall provide and maintain at all times suitable metering and recording devices, approved by the city manager, in connection with each or all sources of private water unless the control manhole provided for in section 13.07.179 shall be equipped with an approved volume measuring and recording device. The volume of private water consumed during the previous month, together with the consumption of public water as determined from the records of the water department, shall be the basis for computing the sewage volume or the owner may install at his own expense an approved metering device to accurately measure flow as before mentioned.
(c) 
When water is contained in a product or is evaporated or is discharged as unpolluted waste in an uncontaminated condition to surface drainage, an application may be made for a reduction in the volume of waste discharged to the public sewer, provided supporting data satisfactory to the director of water utilities city manager is furnished.
(d) 
This data shall include a flow diagram, destination of the water supply and/or wastes, supported by submetering data installed on such process piping at the expense of the private owner.
(Ordinance 6459 adopted 2/21/22)
(a) 
Protection from damage and tampering.
(1) 
No person shall intentionally, knowingly, or with criminal negligence, break, damage, deface, or tamper with any structure, appurtenance, or equipment which is part of the wastewater collection system.
(2) 
Unless approved by the city manager, no person shall cover any manhole, sewer cleanout, or other openings in the wastewater collection system with earth, paving, or otherwise render it inaccessible.
(3) 
No building or structure shall be located on top of the wastewater collection system.
(4) 
No person shall remove the cover (lid) from any manhole, sewer cleanout, or other openings in the wastewater collection system for any purpose except as authorized by the city.
(b) 
Protection from inflow and infiltration.
(1) 
Connections to the wastewater collection system from roof headers, catch basins, unroofed area drains (e.g., commercial carwashing facilities, solid waste container storage areas, etc.) or any other direct or indirect connection which allows inflow from stormwater or runoff to enter the wastewater collection system are prohibited.
(2) 
All portions of the user’s building sewer and/or private sewer system connected to the city’s wastewater collection system directly or indirectly, including, but not limited to, piping, connections, cleanouts, and manholes shall be properly maintained to prevent the introduction of infiltration from entering the wastewater collection system through defective joints, connections, manhole walls or other sources.
(3) 
The city may require users to implement best management practices (BMPs) as specified in section 13.07.793 of this article or take other measures necessary to reduce and/or eliminate inflow or infiltration from entering the user’s building sewer system, treatment devices, or other connections to the city’s wastewater collection system.
(c) 
Storage of chemicals, materials, substances or wastes.
(1) 
No chemicals, materials, or substances, including but not limited to, paints, solvents, boiler or water treatment chemicals, sludges, chemicals, or wastes shall be stored in proximity to a floor drain or other sewer openings. Containers shall be clearly labeled and stored in a place where the chemicals, materials, substances or wastes, in case of leakage or rupture of the container, cannot enter the wastewater collection system.
(2) 
The storage of any chemicals, materials, substances or wastes that leak or have potential to leak or discharge into the wastewater collection system which, because of discharge or leakage from such storage, may create an explosion hazard or in any way have a deleterious effect to the POTW or constitute a nuisance or a hazard to POTW personnel, the general public, the environment, or the receiving stream shall be subject to review by the city.
(3) 
The city manager may require a user to provide reasonable safeguards to prevent the discharge or leakage of stored chemicals, materials, substances or wastes into the wastewater collection system. These safeguards include, but are not limited to:
(A) 
Providing physical containment that is adequate to contain at least one hundred twenty percent (120%) of the maximum volume of the stored chemicals, materials, substances or wastes;
(B) 
Labeling, moving or relocating containers of stored chemicals, materials, substances or wastes;
(C) 
Providing safety data sheets (SDS) or other necessary documentation to identify constituents in the chemicals, materials, substances or wastes stored;
(D) 
Providing temporary spill protection such as booms, pigs or drain covers, or more permanent spill protections such as sealing floor drains to prevent stored chemicals, materials, substances or wastes from discharging or leaking into the wastewater collection system; or
(E) 
Analyzing chemicals, materials, substances or wastes to determine if wastes exhibit toxic or hazardous characteristics.
(4) 
The city manager may also require a user to develop and implement best management practices (BMPs) or a slug control plan as defined in section 13.07.393 to prevent the discharge or leakage of such chemicals, materials, or wastes.
(5) 
The requirements to install safeguards or the city’s approval of slug control plans or BMPs shall not exempt the user from compliance with any other applicable code, ordinance, rule, regulation or order of any governmental authority. Additionally, these requirements or approvals shall not be construed as or act as a guaranty or assurance that the user is, or will be, in compliance with any other applicable code, ordinance, rule, regulation or order of any governmental authority.
(6) 
The costs for implementing any safeguards, slug control plans, BMPs or other requirements established by the city are the responsibility of the user.
