Aclara Improves Billing, Customer Service For Water Utilities   Aclara Improves Billing, Customer Service For Water Utilities
Aclara’s STAR® network is a two-way, advanced metering infrastructure system that delivers robust data communications to water utilities on secure, licensed radio frequencies. The network provides consistent, hourly interval data, accurate and timely billing, and tampering alarms in near real time. The two-way function allows for a synchronized, top-of-the-hour meter reading. The resulting time-stamped meter reads can be used in system reconciliation, allowing utilities to get a better handle on non-revenue water loss. Learn more.

The History Of Drinking Water Disinfection And Improved Monitoring Techniques
By Randy Turner, Technical Director, Chemist, Swan Analytical USA
The relationship between clean drinking water and health has been known for centuries. Disinfection has been performed for several decades; however, the mechanism has been known for only 100 years.
A Water Network For Economic Vitality
By Maury D. Gaston, AMERICAN - American Cast Iron Pipe Company
Those in the water industry know that water is essential for life and brings economic value, but the economic role of water is often not as well understood by the general public. This paper reviews the history and development of our transportation, electrical, and energy infrastructure and then presents a plan for our nation’s water to be augmented from where we have it abundantly to where we badly need it.
50+ Years With Neptune And Building On A Decade Of R900 Technology
By Neptune Technology Group Inc.
The Public Works Utilities of Billings, MT, began their partnership with Neptune Technology back in the 1950s and was an early adopter of Neptune’s ARB absolute encoder meter reading technology in the 1960s.
Submersible Pumps Solve Oxygen (O2) Depletion Problems
By Flygt -- A Xylem Brand
At the Marston Water Treatment Plant, Denver Water shared the seasonal oxygen depletion concerns confronted by many utilities that use surface impoundments as their raw water source. Especially in autumn, customers complained that the water had an undesirable taste, odor, and color. Learn how the utility overcame this problem by installing a 35-horsepower submersible pump that moves five times more oxygen than a conventional aeration system.
Wastewater Treatment Plant Reduces Energy Consumption, Noise With Turbo Blower Technology
By Beth Brindle, Water Online
Built in 1974, the Blue River Wastewater Treatment Plant in Silverthorne, CO, provides wastewater services to the communities of Silverthorne, Dillon, Dillon Valley, Buffalo Mountain, and Mesa Cortina. Faced with rising energy costs and aging equipment, the Silverthorne-Dillon Joint Sewer Authority (JSA) identified a need to replace the plant’s original multistage centrifugal blowers with new technology that would reduce energy consumption and provide steady and reliable operation.

Products And Applications For Steam Generating Plants
When generating steam, dissolved gas control is an integral part of the water treatment system. Historically, vacuum towers, steam deaerators, decarbonators, and chemical injection systems were common methods used to control dissolved gas in water systems in power plants. However, these methods can be much less efficient, require more maintenance, and involve handling large volumes of chemicals.
