Informational Meeting: Operation Baseline

The Sacramento Regional County Sanitation District (Regional San) is currently constructing new treatment facilities at the Sacramento Regional Wastewater Treatment Plant (SRWTP), at a cost of approximately $1.5 B, which are due to be operational in 2021. These upgrades will dramatically reduce total nitrogen levels and alter the concentrations of different forms of nitrogen in the Sacramento River. As a sub-component of the upgrade coming online, the nutrient composition of the treated wastewater effluent may be reduced.


To understand what effects these changes may have on the Delta ecosystem, a baseline needs to be established. Operation Baseline is a set of innovative pilot studies funded by the Delta Stewardship Council to fulfil this need. The studies will assess the current state of nutrients, aquatic vegetation, and the food web in areas that may be affected by the changes in nutrient loading. These studies lay the groundwork to enable comparisons between present and future conditions.


The purpose of this meeting is to inform interested members of the public about the Operation Baseline pilot studies. Project investigators will share their research goals and study plans. This informational meeting will include a public comment period to allow for information exchange and discussion.  For more information about Operation Baseline, click here.

Coequal goals

The Delta Stewardship Council was created in legislation to achieve the state mandated coequal goals for the Delta. "'Coequal goals' means the two goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the Delta ecosystem. The coequal goals shall be achieved in a manner that protects and enhances the unique cultural, recreational, natural resource, and agricultural values of the Delta as an evolving place." (CA Water Code §85054)
