Overview of Sewer Discharge Limits

The City establishes local limits and pretreatment obligations that supplement federal and state wastewater requirements. Local limits typically set maximum concentrations for pollutants such as biochemical oxygen demand (BOD), total suspended solids (TSS), oil and grease, heavy metals and pH. Specific numeric limits and pollutant lists are documented in the City code and utility rules; where numeric values or permit names are not published on the cited city pages, they are noted below as not specified on the cited page.[1]

Permitting & Industrial Pretreatment

Industrial and commercial facilities that discharge non-domestic wastewater into the municipal sewer may need an industrial wastewater discharge permit or must comply with the city's pretreatment program. Requirements commonly include sampling, reporting, source control, and pretreatment technology where needed.

  • Identify whether your facility is classified as an industrial user by reviewing the municipal code and utility guidance.[1]
  • Establish a monitoring plan and keep records of discharge sampling and maintenance logs.
  • Install pretreatment equipment where required by permit conditions or local limits.
  • Submit periodic discharge reports and permit renewals as directed by the utility.
If you discharge process wastewater, check permit and monitoring obligations immediately.

Applications & Forms

The City publishes permit applications and guidance on its utilities pages where available; specific form names, numbers, fees and submission portals are not specified on the cited municipal code page and should be requested from the Public Works/Utilities office.[1][2]
