Requirements of SIUs

What is Required of SIUs?

Besides obtaining an Industrial Discharge Permit, SIUs may be required to install facilities to treat their wastewater to meet applicable pretreatment standards prior to discharging to the sewer system.

SIUs must periodically sample and analyze their discharges to determine compliance, and must report the results to the Districts.

SIUs who fail to comply with pretreatment standards face the possibility of serious enforcement actions, including monetary penalties and termination of sewer service.
