Non-domestic Wastewater Permits

The City of Upland implements the Non-domestic Wastewater Permit (NDWP) Program under the National Pretreatment as part of a cooperative federal, state and local effort to reduce the level of pollutants discharged by industry and other non-domestic wastewater sources into the municipal sewer system.

  • To protect the integrity of the treatment plant and sewer collection system
  • To protect the health and safety of workers
  • To prevent pollutant pass through or plant interference
  • To protect the receiving waters (Santa Ana River)
  • To protect the quality of bio-solids allowing for beneficial uses

The City of Upland’s NDWP program monitors the discharge activities of permitted industrial users, commercial users and other non-domestic wastewater dischargers. Program activities include site inspections, permit writing and administration, sampling, maintaining an industrial waste survey, compliance and enforcement, program billing, program development and technical assistance.

What New Businesses to the City of Upland Should Know!!

If your business is new to Upland, contact the Pretreatment Coordinator for more information on sewer usage. If needed, the City will send you a one page Industrial Wastewater Survey. The survey includes questions about your facility, water usage and chemicals that could enter the sewer. It will be used to determine if a permit is required for your sewer discharge. The survey must be returned within 30 days and will be kept on file at the Environmental Division offices. If there are any changes to your process waste stream, a survey update is required.

Permits are required for all industries that:

  • are subject to national categorical pretreatment standards: 40 CFR 403.6 and 40 CFR Chapter I, Subchapter N
  • have process discharge volumes averaging 5,000 gallons per day or more
  • have discharge volumes that make up 5% or more of the (avg. dry weather hydraulic or organic) WWTP capacity
  • are designated as a 'significant user' by the City based on potential to adversely effect the POTW
It is the business owner's responsibility to obtain the required permits.
