Project AWE is an educational program of the Sacramento Regional County Sanitation District (Regional San). Regional San owns the Nicolaus Dairy site and has provided the major funding for site renovations and creation of the Project AWE education programs.  Operation of Project AWE programs falls under their supervision. 

Regional San owns and operates the regional wastewater conveyance system and the Sacramento Regional Wastewater Treatment Plant, located near Elk Grove, California. Regional San serves a population of about 1.4 million residents in the region.

Our Mission

Regional San protects public health and the environment by conveying, treating, and recovering resources from wastewater responsibly and cost-effectively.

Our Vision

Regional San is a leader in environmental stewardship and a trusted partner in regional sustainability.

At Regional San, we provide wastewater conveyance and treatment services to residential, industrial and commercial customers throughout unincorporated Sacramento County; the cities of Citrus Heights, Elk Grove, Folsom, Rancho Cordova, Sacramento, and West Sacramento; and the communities of Courtland and Walnut Grove. (View a map of our Service Area.)

Wastewater is collected from customers’ homes and businesses via sewer collection pipes operated by one of four local sewer agencies. These pipes connect to our network of 169 miles of interceptor pipelines, which convey the wastewater to the Sacramento Regional Wastewater Treatment Plant. There, approximately 130 million gallons of wastewater are treated daily and safely discharged to the Sacramento River.

Regional San was formed in 1973, and in 1982, after years of construction, the Sacramento Regional Wastewater Treatment Plant began service. Regional San is governed by a 17-member Board of Directors, representing all of the jurisdictions we serve throughout the region.
