Union Point, GA
Sherrills Creek Reservoir in Union Point, GA had a triple dose of problems. This 48-acre lake was laden with high levels of manganese and iron, giving the water an unnatural dark color and causing it to stain their customers’ clothes and plumbing fixtures. Also, a proliferation of blue-green algae blooms resulted in finished water with an unpleasant taste and odor.
Palmdale, CA
The treatment plant and reservoir at Palmdale, California always strives to maximize water quality. Part of the challenge was blue-green algae that choked the reservoir all summer, giving the water bad taste and odor.
Glendale, CA
Glendale Water and Power has long been on the leading edge when it comes to water treatment in their plant and distribution system. Patrick Hayes uses chloramine as the main disinfection method, both to comply with DBP rules and to keep Glendale’s water as fresh as possible. Over long retention times, chloramine can break down and cause unhealthy nitrification. To prevent this, Glendale installed SolarBee® long-distance water circulators in their storage tanks. The SolarBee® provides thorough mixing of the entire tank, keeping temperature stratification and stagnation to a minimum.
Bend, OR
A new clearwell reservoir gave Bend, Oregon an additional 2.23 MG of water capacity. But summertime brought thermal stratification and short-circuiting, making the tank’s chlorine disinfection effectiveness too low for comfort.
"Contact time was down to 30 minutes," reported Chris Brelje. So Bend installed a SolarBee® solar-powered water circulator inside the tank, placing the intake hose on the reservoir floor, directly between the inlet and outlet pipes.
