  • Shed The Lead

    When is a water meter truly “green”? In addition to meeting lead free regulations, it should also provide utility users with recyclability, field-proven durability – and just as important – superior scrap value at end of life. This video examines how traditional lead-free bronze-body meters offer all of the above – something that cannot be said for non-recyclable plastic or composite water meters.

  • Send In The Bugs: Biological Filtration Solves Contaminant, Capacity Concerns
    Send In The Bugs: Biological Filtration Solves Contaminant, Capacity Concerns

    Every drinking water system is part of the community it serves, but not quite like Waterford Township, MI, where treatment plants sit side-by-side with homes. The unique, decentralized system utilizes 13 separate treatment plants to clean the local, iron-rich well water. Due to “explosive growth,” the municipality needed to bolster the water supply with more wells, but had zero room for plant expansion. How do you treat more water in the same space?

A new Flygt N-Pump has changed the utility’s course, however, proving with one (easy) installation the cost savings that can be gained through advanced impeller technology and remote SCADA operability.

  • WWEMA Window: Challenges For Technology/Innovation Approval In The Municipal Market
    WWEMA Window: Challenges For Technology/Innovation Approval In The Municipal Market

    The United States continues to advance as a society, embracing innovation in everything from genetics and medicine, to energy and materials.  The drinking water and wastewater industry, however, is not evolving at nearly the same pace. We still sell technologies that are 80 years old. That is not to say these technologies do not work; in fact, many still work extremely well. But our reluctance to adopt new solutions and technologies, as an industry, often means less cost-effective solutions for customers. By John D. Dyson, Director of Business Development, Severn Trent Services
