Join us for a free tour to get a first-hand look at what it takes to remove human waste and other pollutants from millions of gallons of wastewater each day. Tour attendees must be 10 or older and children under 18 must be accompanied by an adult. For more information, please call Kit Ohlman at (925) 229-7329.
