Known for "Healing Waters," Pagosa Springs Restores Potable Water System With Help From SolarBee Mixers

H2bid - The World's Water Blog - Sat, 10/11/2014

Pagosa Springs, Colo. – Located in the high desert plateau of southwestern Colorado, Pagosa Springs is famous for its geothermal hot springs, which draw visitors worldwide to soak in the mineral-rich water. The Utes called the sulfur springs “Pah-gosah,” meaning “healing waters.” You might say the town’s potable water system is healed now as well.

Solving the blue-green algae problem: Mechanical circulation as a way to win the algae battle

MarketWired - Wed, 09/17/2014 - By Joel Bleth

Harmful blue-green algae blooms (HABs) in lakes have made headlines this summer throughout the country. HABs can disrupt municipal potable water systems, forcing residents to rely on bottled water, and have closed beaches on many recreational lakes. Worse than looking and smelling bad, HABs can also cause nausea, diarrhea, skin and throat irritation and breathing difficulties for people; for their pets, the toxins can cause death.  

What's the Buzz? Two SolarBee Units Installed at West Lake, Osceola, Iowa

Osceola Sentinel-Tribune - Wed, 04/23/2014 - By Amy Hansen Ost


Solar Bees are buzzing at West Lake.

On April 9 and 10, two Solar Bee units were installed into the lake.

“They’re trying to concentrate up around the intake (areas) going into the plant,” said Osceola Water Superintendent Brandon Patterson.

Solar Bees, which look like pumps or fountains that disperse water, are solar powered and placed in lakes to provide long distance circulation, which helps control harmful blue green algae blooms, reduces taste and odor issues, improves fish habitats and overall water quality.


Can Mixing a CT Tank Increase the Baffle Factor?

Opflow Magazine - Tue, 07/16/2013 - By Joel Bleth

Water and wastewater utilities can account for nearly 40% of a small city's energy use. By more efficiently managing its energy use, a community can significantly affect operational costs and improve its financial sustainability.

Proper mixing increases detention time by adding a vertical plug-flow element to the flow of water through a chlorine contact tank. The increased detention time allows a plant operator to use a higher baffling factor used in contact time (CT) calculations, thus reducing the concentration of chlorine needed to meet CT treatment requirements.

Waterbody Management Must Be Implemented | Commentary

Capital Hill newspaper - CQ Roll Call - Wed, 05/15/2013 - By Andrew Garfinkel and H. Kenneth Hudnell

Congress must ask the Environmental Protection Agency why, after more than
40 years of increasingly costly watershed management (WSM) technologies and
best-management practices, water quality is continuing to deteriorate. Since
enactment of the Clean Water Act in 1972, controlling point- and nonpoint-source
nutrient and pollutant loading from watersheds into waterbodies has been the
EPA’s sole method of addressing waterbody impairment. The agency failed to

SolarBees make lakes more livable

The Press-Enterprise - Wed, 11/28/2012 - By Dayna Straehley, Staff Writer

Two floating, solar-powered aeration units intended to improve the health of the lakes at Fairmount Park have so far made the water clearer, says the city councilman who represents that downtown Riverside area.

“I’ve been really happy with them,” Councilman Mike Gardner said about the SolarBees, which the city purchased with a $100,000 Custom Energy-Efficiency Technology Grant.

"Thumbs Up" for Michigan: WWTP meets phosphorous discharge numbers

Water and Wastes Digest - Tue, 05/15/2012 - By Grant Thornburg

The “thumb” of Michigan, outlined by Saginaw Bay and Lake Huron, is a peninsula rich in lakes, rivers and streams. Given the ecologically sensitive territory, smaller towns with limited resources can find it challenging to meet state mandated wastewater discharge permit levels. The Population 1,035 village of North Branch, about 30 miles northeast of Flint, faced problems of excessive phosphorous in its four-pond facultative system.

SolarBee earns St. Helens a state award

The St Helens Chronicle - Fri, 01/27/2012 - By Shari Phiel

ST. HELENS - Last February, the City of St. Helens was looking for a way to reduce costs at its primary treatment lagoon, while ensuring the lagoon was still properly aerated and mixed. The city found its answer in the purchase of two Solar Bees, solar-panel-run sludge mixer. That decision recently won them the state award from the Oregon Leaders Award.

Solar helps city save $108,000 in energy costs

SolarBee pumping project may lower mercury levels in Utah reservoir

The Salt Lake Tribune - Mon, 08/15/2011 - By Mark Havnes

Newcastle • Scientists at Newcastle Reservoir are stirring things up to see if a new technique using a solar-powered pump will reduce high mercury levels in the water. If it works, the procedure may be used on other contaminated bodies of water in Utah.

Newcastle is one of 16 bodies of water in Utah that have mercury levels high enough to prompt advisories about eating fish caught in them.

Hydrologists with the U.S. Geological Survey placed the platform pump in July near the dam of the reservoir, which is about 30 miles west of Cedar City.

Still Waters Run You Ragged

Stormwater - Mon, 08/01/2011 - By Janis Keating

Ponds can be a boon and a bane. For retaining or detaining water from a stormwater system, or within a site, they serve their purpose well; in addition, ponds can greatly enhance a site’s aesthetic appeal. On the flip side, however, that standing water can become an eyesore at best, a health hazard at worst. But keeping algae and breeding mosquitoes at bay can be a simpler matter if one takes a tip from nature—by keeping the water moving. Towering falls or raging rapids aren’t required; simple fountains, aerators, or bubblers can often do the trick.

Cypress swamp regains water quality with help from SolarBee circulators

Water and Wastes Digest Case of the Week - Fri, 07/22/2011 - By Patrick J. Schnaidt

Award-winning circulation technology reduces blue-green algae.

Greenfield Lake, an idyllic cypress swamp surrounded by walking paths and bridges, is a popular recreation area in Wilmington, North Carolina. Residents and visitors enjoy picnicking, gardens, an amphitheater, boating and fishing.

But when blue-green algae took over the swamp, the water turned to pea soup and weeds grew thick along the shore. The shallow, 100-acre reservoir is primarily fed by stormwater via several drainage pipes throughout the basin. Boaters preferred to go elsewhere.

SolarBees to curb water discolouration this summer

The Drumheller Mail - Tue, 05/24/2011 - By Kyle Smylie

The Solar Bee circulation equipment has been installed in the town’s four water reservoirs to curb the water discolouration Drumheller residents saw pouring from their taps last fall.

The price tag included installation and delivery of the solar powered devices, and was approved by council in January.

“They’ll initiate some savings in power, chemical and hopefully down the road some time,” said Director of Infrastructure Allan Kendrick. It will reduce chemicals used to treat the water by treating it the natural way by keeping the water circulating.

SolarBees Are In Town - Drumheller, AB Canada

Drumheller Online - Fri, 05/13/2011 - By Grant Daly

SolarBee and H2O Logics have begun to install their water circulation devices in the valleys reservoir. The new devices were purchased by the town to help improve the quality of water entering the towns water plant.

SolarBees are designed to circulate water and control the growth of blue and green algae. The state of the art machines are programed to run at different speeds, adjusting to the time of day or season.

The magnetic motors for the water circulation devices are powered by solar panels, requiring no outside power source, and helping keep costs low.

SolarBee mixers improve water quality for Yuma, AZ residents

Whoever said tanks were just for holding water? In Yuma, Arizona, the city’s three potable water tanks are works of art. Featuring colorful murals of the local landscape, the 50-foot high and 100-foot wide tanks are a drive-by gallery on display to anyone on Interstate 8. What’s more important, of course, is the quality of the water inside the tanks. Thanks to SolarBee mixers, Yuma’s drinking water is now picture-perfect.
