We work diligently to understand your wastewater requirements. In doing so, we are able to provide oversight and assistance in times of need.


Wastewater discharges from industrial and commercial sources may contain pollutants at levels that could affect the quality of receiving waters or interfere with publicly owned treatment works (POTWs) that receive those discharges. The National Pollutant Discharge Elimination System (NPDES) permitting program establishes discharge limits and conditions for industrial and commercial sources with specific limitations based on the type of facility/activity generating the discharge.

How often do I need to revise or modify my Wastewater Permit?

Permits are issued on a case-by-case basis for facilities. Revisions or changes to a permit occur with the following:

  • Changes in ownership
  • 25% or more change in wastewater quantity/quality
  • Modifications to the wastewater conveyance/pretreatment system
  • Permit expirations, dependent on the permit specifications. Usually every 3 years, but varies on jurisdiction.
What is an Annual Wastewater Surcharge Statement?

State and Federal programs require that industrial companies discharging to publicly owned sewerage systems should pay their fair share of wastewater treatment costs. The surcharge statement is required to be filed by any business discharging industrial wastewater directly or indirectly to the sewerage system of the Sanitation Districts.

Exemptions may be made for companies discharging an insignificant amount of wastewater.

What is a Self-Monitoring Report and why is sampling required?

Several regulators ask for Self-Monitoring Reports to be submitted on an annual basis. This can be either grab and/or composite samples depending on the permit/jurisdiction requirements. Analysis at a state certified lab allows regulators to review the results with benchmarks and parameters for the specific industry.

  • Sampling is a method to monitor internally, usually with the assistance of a 3rd party contractor.
  • Most permits require a notification to be made to the sanitation district, in the event, they want to be present or to send an inspector into the sewerage systems for a reference sample.
  • Sampling frequency is dependent on the volume of wastewater discharged, specific industry, history of compliance, and material processes.


We have experience working with a variety of different regulators. Such as Department of Public Works, Bureau of Sanitation Districts, and Industrial Waste Management Divisions. Each function in a similar way, with different requirements depending on jurisdictions.
