August 27, 2019: Valve Turning Ceremony for the Sea Pines Golf Resort Recycled Water Connection Proposed Los Osos Sewer Rate Increase - Public Hearing Information

There will be a valve turning ceremony to celebrate the completion of the first recycled water connection from Los Osos Water Recycling Facility to Sea Pines Golf Resort.  The event will take place on Tuesday, August 27, 2019, at 10:00 a.m. at Sea Pines Golf Resort intersection of Glenn Street and Howard Avenue in Los Osos and will include light refreshments. The Los Osos Water Recycling Facility was designed to deliver highly treated wastewater for irrigation and other purposes to promote sustainability within the Los Osos Groundwater Basin. Sea Pines Golf Resort is the first connected to receive recycled water for irrigation use since the plant began operation in 2016. The recycled water they receive supplements up to 200,000 gallons of groundwater water per day, which would otherwise be pumped from the Los Osos aquifer. Additional recycled water connections are planned for other high demand water users.
