      • The Buzz in Beantown

        On June 8-12, the American Water Works Association will host its Annual Conference & Exposition at the Boston Convention & Exhibition Center in Boston, Mass. Considered one of the leading water industry conferences and exhibitions in the nation, the event will provide a wide range of valuable resources and opportunities for its numerous attendees.

      • City Installs Valves Without Loss of Service, Fire Protection

        The Water Distribution Department in Ponca City, Okla., needed to install three 24-inch valves in its main feed pipeline without service loss. The city therefore chose 635 mm EZ valves from Advanced Valve Technologies and consequently could control its water supply with no loss of service or fire protection to its customers.

      • Wingo Water & Sewer: First to Install Fixed Network System in Kentucky

        When it came time to upgrade its meter reading system, the small town of Wingo, Ky., wanted a comprehensive water utility solution. As such, it chose the ORION Fixed Network (SE) system from Badger Meter.

      • Seismic Design: Considerations in Water Storage Construction

        Driven by its commitment to provide a reliable distribution as well as the need for additional fire flow capacity following the tragic Cedar Fire, the Padre Dam Municipal District in Southern California replaced an existing 1.5-million-gallon (MG) water storage tank with a 2.5-MG prestressed concrete tank in the suburb of Alpine, Calif.

      • Turning Data into Decisions: How Analytics Can Help Make the Most of Meter Data

        Water utilities are facing non-revenue water, increasing demand and timely revenue collection. Fortunately, new and affordable analytic tools, such as Itron Analytics, turn data into actionable intelligence, enabling plants to quickly and accurately address these issues in an ongoing and sustainable way.

      • Pressure Management Using Piezoresistive Silicon Sensing Element

        Piezoresistive technology is mature and well understood. Having replaced the bonded/unbonded strain gauge and thin-film technologies decades ago, it is now the most readily mass-produced and cost-effective method of converting pressure into an electrical signal.

      • High Viscosity: Polymer Measurement Challenges and Solutions

        One of the challenges in the measurement of products used in wastewater and water treatment arises when the fluid being measured is very viscous. Case in point: polymers used in wastewater treatment plants.

      • Intelligent Analytics Software Gives Dubuque Customers Higher Water IQ

        The city of Dubuque, Iowa, Water Department converted its approximately 22,500 water meters to Neptune’s two-way, full fixed network AMI system. After seeing its success, the city became one of the first utilities to adopt Neptune’s new, cloud-based N_SIGHT™ IQ to leverage that data.

      • More Efficient Ozone Generation Improves Dissolution and Reduces Water Treatment Cost

        Ozone technology has improved in the last couple of years as high-concentration ozone generators have hit the market. Accordingly, Primozone offers a series of high-performance ozone generators aimed at industrial, municipal and aquaculture applications.

      • One Valve ‘Does It All’ for Yarra Valley Water Station

        Yarra Valley Water’s Wandin North site in Melbourne, Australia, had three Pressure Reducing Valves (PRVs) of differing sizes, all without anti-cavitation trim. The 2” was replaced with a 6” Single Rolling Diaphragm from Singer Valve fitted with Anti-Cav Trim, removing the need to protect the other two valves with the trim.

      • Lee’s Summit: Water Main Pipe Bursting Program

        The city of Lee’s Summit, Mo.’s water department distributes water through a 580-mile-long system of water mains, comprised mainly of cast iron and ductile iron pipe, which in the clay soils has created significant corrosion concerns. As such, the city replaced those mains suffering the greatest repair frequency with Fusible PVC pipe.

TODAY'S HEADLINES

Clearing Things Up at Prequannock WTP

In 2010, the city of Newark, N.J., retained Hatch Mott MacDonald to investigate potential solutions to a problem at Pequannock WTP. Decant tanks were providing minimal solids removal as a result of removed tube settlers from deterioration. Inclined plate settlers were identified as a feasible alternative for improving supernatant water quality and were selected for pilot testing.

Be the Change: Embracing New Approaches to Foster Innovation in the Water Industry

The pressure to accommodate change will drive our traditionally risk-averse industry to embrace new and different approaches at an accelerated pace. Further, the demand for a zero-energy footprint will also drive improvements in co-generation efficiencies, energy conservation and recovery methods, and comprehensive resource recovery.

CDC preparing Ebola guidance for wastewater treatment personnel

In a recent conference call with AWWA and other major water organizations, the CDC shared it has prepared and is conducting an expedited internal review of an interim guidance on wastewater worker safety and the inactivation of the Ebola virus by wastewater treatment processes.

New partnership to measure farmers' conservation impacts on U.S. water quality

The U.S. Department of the Interior and U.S. Department of Agriculture have announced a new partnership that will provide a clearer picture of the benefits of farmers' conservation practices on the quality of the nation's waters.
