Graton Wastewater Treatment Facility Upgrade
Graton Community Service District, Sonoma County
Project Abstract
The Graton Wastewater Treatment Plant Upgrade generally consists of improvements to increase efficiency and reduce energy consumption in the secondary aeration process, covering of the secondary settling pond to reduce algae growth, and the addition of phytoremediation and filtration to meet Title 22 requirements for all reuse purposes and comply with the North Coast Regional Water Board Basin Plan. Reclaimed water will be used to irrigate approximately 200 acres of vineyard, redwoods, native grasses and woodlands.
Project Goals
- Eliminate secondary wastewater discharge, reduce total discharge to Atascadero Creek, and improve surface water quality and quantity in Atascadero Creek and the Russian River.
- Comply with the Regional Water Quality Control Basin Plan and NPDES permit requirements.
- Reduce life-cycle costs of wastewater treatment by providing sustainable, ecological, energy-efficient and beneficial treatment of wastewater.
- Utilize reclaimed wastewater effluent for irrigation, local groundwater recharge, and enhancement of riparian vegetation.
- Reduce up-gradient non-point source pollution from agricultural land uses through phytoremediation.
- Reduce domestic, agricultural, and industrial groundwater withdrawal through water conservation and irrigation with reclaimed water.
- Increase water flow in Atascadero Creek by enhancing groundwater flow to riparian vegetation.
- Enhance wildlife habitat in riparian corridors and wetlands.
- Provide opportunities for public education and recreation.
- Control influent contamination through:
- management of infiltration,
- source control programs including educational programs and incentives.
