Industrial Pretreatment

Permission To Discharge to Sanitary Sewer

Since every waste stream is unique, businesses should contact the IP Program to obtain permission to discharge to the sanitary sewer.

Be prepared to provide the following information:

• types and amounts of pollutants the wastes contain- MSDS and sample analyses may be required;
• industrial wastewater classification survey (pdf);
• total volume of the wastes;
• how the wastes will be discharged; and
• frequency of the discharge (one time, intermittent or continuous).

Discharges must not violate any of the general prohibitions of the Code 14.08.310. Contact IPP if the wastes exceeds any local limit listed in 14.08.312.

Discharge must not cause pass through or interference of the POTW.

Sampling

All costs associated with sampling a waste are the responsibility of the discharger.

Surcharges Applicable

The treatment plant may accept high strength wastes. High strength is considered wastes with pollutant loadings greater than domestic values (BOD>300 mg/L, TSS>330 mg/L or TKN>45 mg/L). Surcharges are applicable. Slug loads are prohibited.
