The EchoWater Project Name
We're calling this major upgrade the EchoWater Project to reflect how it will take our wastewater and return it to a clean, natural state, much like an echo returns to its original source.

The EchoWater Project is being built by the Sacramento Regional County Sanitation District (Regional San) to meet stringent new treatment mandates by the State of California. This requires us to make the most significant upgrades to our wastewater treatment plant in Elk Grove since its construction more than 30 years ago. This new system, which must be operating by 2023, will produce cleaner water for discharge to the Sacramento River and increase water recycling opportunities by producing highly treated water that meets water reuse standards.

Improved Treatment Processes
Ultimately, EchoWater will boost plant processes to a higher level of treatment, featuring biological nutrient removal for ammonia and nitrates and advanced filtration and disinfection for pathogens. Currently, Regional San wastewater undergoes secondary treatment, which involves separation of solids, biological treatment to break down small organic particles, and disinfection with chlorine. While more than adequately meeting previous discharge requirements, only a full-scale expansion of our secondary process and the addition of new tertiary filtration will achieve compliance with the strict new mandates.

Benefits of the Project
The EchoWater project will provide long-term benefits to water quality and the environment. The improved quality of the treated wastewater released into the Sacramento River will help reduce potential impacts on the ailing Delta and protect recreational users downstream. The treatment technology required to meet the new regulations will provide Regional San with a ready supply of recycled water to deliver to future water recycling projects. Additionally, using recycled water helps preserve our precious water supplies, especially during drought conditions.

Cost of the Project
It is estimated that these new processes will cost between $1.5 billion and $2.1 billion to construct, plus approximately $50 million per year in additional maintenance and operations costs. These costs will be borne by ratepayers, with rates expected to rise to the mid-$40s to low $50s per month between 2021 and 2023. These increases, which have already begun, will be phased in gradually as the project is developed. Fees for connecting new homes and buildings to the system will also increase.
