City of Riverbank to increase groundwater recharge and improve water quality
Riverbank, California: $50 million
Project Description
The city of Riverbank, a community of about 25,000 with pockets of disadvantaged residents will expand capacity at water treatment facilities and retrofit their existing wastewater treatment facilities to mitigate impact to the city’s wells from severe, extreme and exceptional drought conditions. Nature-based solutions will be used, such as recharging groundwater using the city’s existing ponds and by delivering recycled water to agricultural users. The location of these capacity enhancements will provide specific benefits to groundwater recharge, quality and availability to the city’s potable water well system.
The project will promote the flow of high-quality Stanislaus River recharge water towards the city’s wells. The project design also enhances the natural benefits of recharge from the Stanislaus River to the city’s wellfield by inducing favorable groundwater flow and enhanced quality recharge into the Modesto sub-basin. Once done, this project will expand capacity from 1.6 to 2.29 million gallons per day of influent flow, allow the city’s percolation ponds to be used for multi-benefit purposes, and increase groundwater recharge.
