Known for "Healing Waters," Pagosa Springs Restores Potable Water System With Help From SolarBee Mixers
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.
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.
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.
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.
Understanding the science behind water stratification in storage tanks can help utility operators and managers determine how to remedy the problem and ensure customers receive the highest-quality water.
Lake Varner and City Pond provide drinking water and offer recreational activities to the residents of Covington and Newton County. Lake Varner is an 850-acre drinking water reservoir completed in 1992 that is known as an excellent fishing destination. City Pond encompasses much of City Pond Park, which offers six-lighted baseball fields, an open park and two miles of walking trails.
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
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.
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.
A Dickinson company has been named a “rural manufacturing success,” earning it a ticket to Washington D.C. in one week, officials said Friday.
SolarBee Inc. has accepted an invitation from the White House and the U. S. Department of Agriculture to attend the “Recognition of Manufacturing Success in Rural America” event, which will be held Friday, Feb. 17. SolarBee co-founder and president Joel Bleth will be attending the event as a representative.
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.
Efforts to cut down on energy costs have paid off nearly one year after the city of St. Helens installed solar-powered mixers in its wastewater lagoons.
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.
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.
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.
High Efficiency Units to Improve Raw Water Quality
Starting Tuesday, July 12, 2011, Department of Public Works contractors will install high efficiency solar-powered water circulators in Prince Reservoir and Erie Reservoir. Increased circulation of the water in the reservoirs will improve the quality of the Town’s raw water supply allowing staff to make adjustments in the operations of the Water Treatment Facility with minimal impact to our customers.
Other benefits of the water circulators include:
Solar-powered device to be tested for improving water quality
Something new is floating in the Inner Harbor. Not litter this time, but a space age-looking gadget meant to see whether new life can be breathed into the troubled body of water.
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.
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.
There is a little piece of paradise in the foothills of the upper Piedmont area of North Carolina, but most residents just call it Eden. Like many small towns, Eden is prized for its unique attractions—a vintage drive-in movie theater, annual bluegrass concert and rubber duck regatta, to name a few—as well as proximity to big-city conveniences.
St. Helens hopes for eventual savings with new solar wastewater mixers
The purchase of nine new solar-powered wastewater mixers in St. Helens, to be used in the primary and secondary wastewater lagoons at the Wastewater Treatment Plant, is the realization of a decade-long energy-saving plan for the city’s facility.
The first seven of the mixers were bought last fall for use in the secondary lagoon, which receives waste from Boise Inc.'s paper mill facility, while two more will be purchased this week to be used in the primary lagoon.
Glendale (Calif.) Water & Power (GWP) operates and maintains a potable water system serving approximately 210,000 people with 380 miles of distribution system piping and 28 storage facilities. The potable storage facilities consist of in-ground reservoirs, aboveground steel tanks and partially buried reservoirs with storage capacities that range from 80,000 gal to 57 million gal. The tallest storage facility is a more-than-50-ft aboveground tank with difficult road access.
Solar-powered mixers from SolarBee are designed to solve municipal wastewater quality problems including odor control, discharge permit violations, and high energy costs. The mixers operate continuously, reducing BOD, TSS and ammonia. They also can supply most of the mixing energy required in a treatment pond. Flow rates vary by mixer size, ranging from 1,250 to 10,000 gpm.
