Below are some common questions from our partners. If you can't find what you're looking for contact our Source Control department at email@example.com or 503.681.5175.
The United States Environmental Protection Agency (USEPA) has mandated the use of industrial pretreatment to keep pollutants and substances that disrupt wastewater treatment processes out of the sanitary sewer system. This requires controlling them at the source.
Clean Water Services is responsible to Oregon Department of Environmental Quality (DEQ) and USEPA for regulating and enforcing pretreatment requirements in urban Washington County and small parts of Multnomah and Clackamas counties. Clean Water Services monitors permit compliance on a regular basis. We are required to report the facility name and type of non-compliance committed by significant violators each year.
Enforcement actions can range from a telephone call to a civic penalty and request to stop discharging. Industrial pretreatment protects water resources and promotes conservation by recovering industrial byproducts, chemicals and metals at the source. It also allows the use of clean biosolids and effluent for agriculture.
If you discharge anything other than sanitary or domestic wastewater, you must contact Clean Water Services about a permit. Process wastewater, carwash water, lab waste and contact cooling all require a permit application (PDF, 1MB). Applications must be submitted at least 90 days before wastewater disposal. The purpose of the permit application is to identify the volume and characteristics of the wastewater to be discharged into the sanitary sewer.
You may be classified as one of the following:
One or more of the following applies:
CWS will issue industrial wastewater discharge permits to SIUs where pollutants of concern are, or have the potential to be, discharged at levels that could: impact Clean Water Services, impact the environment, or affect worker health and safety.
An NDCISU is an industrial user that is considered categorical, but that discharge no process wastewater to the sanitary sewer system. You will be issued a Non-Discharger Categorical Industrial User Permit (NDCIU).
A Non-significant industrial user discharges process wastewater, but does not meet the Significant Industrial User definition. CWS may elect to issue discharge permits to Non-significant Industrial Users under a local control program.
Examples of such industries may include, but are not limited to:
CWS elects to issue a permit without the need for monthly reporting or frequent oversight.
Examples of such industries may include, but are not limited to:
Clean Water Services (CWS) will supply a permit application booklet. Submission of a completed discharge permit application is required at least 90 days before discharging wastewater. CWS will review your application, and if approved, prepare a disposal permit that lists discharge and other requirements.
To request a permit, call 503.681.5175 or download a discharge permit application form (PDF, 1MB).
Significant Industrial Users (SIUs) are required to submit reports to Clean Water Services (CWS), which are listed in your discharge permit. CWS provides assistance in completing the initial forms for these reports.
|Type of Penalty||Amount: The following penalties apply to Daily Maximum and Monthly Average Violations|
|First Offense||Written notice|
|pH||Daily: No monetary penalty amount
|Second Offense||Total of the following amounts, as applicable:|
|Volume||$3.27 per 100 cu. ft. over the allowed permit limit|
|pH||Daily Maximum: $25
|Conventional pollutants||$100 per constituent per day that exceeds the permit limit (COD, TSS, etc.)|
|All other pollutants||$150 per constituent per day that exceeds the discharge permit limit|
|Third Offense||Total of the following amounts, as applicable:|
|Volume||$5.56 per 100 cu. ft. over the allowed permit limit|
|pH||Daily Maximum: $50
|Conventional pollutants||$200 per constituent per day that pollutants exceed the permit limit (COD, TSS, etc.)|
|All other pollutants||$350 per constituent per day that exceeds the discharge permit limit|
|Fourth Offense||Stoppage of sewer service and/or water service if additional capacity is not purchased or if appropriate pretreatment facilities are not scheduled and, thereafter, constructed in a timely fashion as determined by the District. Penalty fees continue until permit limits are met.|
|Volume||$11.16 per 100 cu. ft. over the allowed permit limit|
|pH||Daily Maximum: $100
|Conventional pollutants||$600 per constituent per day that pollutants exceed the permit limit (COD, SS, etc.)|
|All other pollutants||$800 per constituent per day that exceeds the discharge permit limit|
In addition to applicable Federal pretreatment standards, dischargers must stay within limits based on local wastewater treatment plant specifics. No Significant Industrial User (SIU) is allowed to discharge wastewater containing concentrations (and/or mass limitations) of substances exceeding the limits below.
|Constituent||Max Allowable (mg/L)|
|Fats, oil & grease||BMP|
|Total Toxic Organics*||N/A|
|pH||6.0 - 11.0|
*Clean Water Services is not proposing a single local limit for these pollutants. CWS may, at its discretion, restrict or prohibit the discharge of other items of concern not mentioned here.
If the Federal pretreatment standards mentioned above are applicable, then the more stringent discharge limit will apply.

Connection fee cost is based on the average monthly industrial process wastewater volume you plan to release into the sanitary sewer system. The calculation for industrial connection fees are based on the number of residential Equivalent Dwelling Units (EDU). One industrial EDU equals 625 gallons per day.
Each month you are charged for the actual amount of industrial wastewater discharged into the sanitary system, plus any high strength surcharge that applies. The units used in calculating the monthly service fee is Hundred Cubic Feet (CCF) which equals 748 gallons.
If your waste exceeds 800 mg/L of Chemical Oxygen Demand (COD) or 400 mg/L of Total Suspended Solids (TSS), fees are levied in addition to actual flow charges.
