A two-year drought is helping to boost Napa County’s recycled water use to record levels. The Napa Sanitation District wastewater treatment plant provides enough non-potable irrigation water annually to fill St. Helena’s Bell Canyon reservoir and more.

Napa Valley Country Club in rural Coombsville started piping water from the plant six miles away in late 2015. That allows it to depend less on a well in an area where groundwater levels have long been a concern.
