SRCSD Service Levels

SRWTP Odor Events:

An odor event occurs when there is a release of odors from the Sacramento Regional Wastewater Treatment Plant site that is easily recognized by the average person.
[more detailed descriptionAn odor event is a release of odors at levels that can contribute to nuisance conditions beyond the Sacramento Regional Wastewater Treatment Plant (SRWTP) property boundary and is confirmed to be caused by District operations. The data is expressed as the number of odor events per 12 months.]

Target

A numeric target has not been set at this time. SRCSD will continue to collect data in coming years and establish a target in the future.

Assessment: Typically, SRWTP is responsible for no more than a few noticeable odors off of the property each year. There were no SRWTP odor events in 2006 or 2007.

Purpose

This service level reflects the effectiveness of odor control equipment and practices at the SRWTP.

Critical Activities

Odor events can be caused by failure of odor control equipment; overloading or mis-management of solids storage basins; failure to adequately inject solids at the dedicated land disposal facilities; prolonged diversion of wastewater to emergency storage basins; failure to adequately clean emergency storage basins; and uncovering wastewater tanks, vaults, or manholes for prolonged periods. Odor events can also be caused by the Biosolids Recycling Facility. Odor events are highly influenced by weather conditions.
