Industrial Pretreatment Program Protects Health & Environment
SD1’s industrial pretreatment program regulates discharge from commercial and industrial facilities as required under the federal Clean Water Act. The program is designed to:
Prevent pollutants that would interfere with the treatment process from entering SD1’s sewer system
Prevent pollutants that can’t be treated from entering and passing through SD1 facilities into the environment
Reduce health and environmental risks caused by pollution
This program regulates industrial discharges through wastewater sampling and on-site inspections of industrial facilities in SD1’s service area.

Permits for Industrial Users
Permitted users must understand which wastewater treatment facility receives their industrial wastewater flow, as well as the effluent limits (PDF) that apply to that facility. Permitted users can find more information on the rules that apply to them in SD1’s Rules and Regulations (PDF).
Industrial User Categories
Industrial users fall into two categories:
Significant Industrial Users (SIUs)are users with one or more of the following traits:
Have potential to adversely affect SD1 treatment plants
Discharge 25,000 gallons of processed wastewater per day, on average
Contribute 5% or more of the average dry-weather hydraulic or organic capacity of the treatment facility
Categorical Industrial Users (CIUs) are a type of SIUbut are also subject to categorical pretreatment standards and have the following traits:
