• Myth Vs Truth: “If My Disinfectant Residual Is Always High Enough, I Don’t Have To Worry About Microbes"
    Myth Vs Truth: “If My Disinfectant Residual Is Always High Enough, I Don’t Have To Worry About Microbes"

    Monitoring disinfectant residuals (i.e. Free and Total Chlorine and/or Chloramine concentration) is one of the most essential practices in drinking water management programs.  This ensures that sufficient protection is maintained at all points in the distribution system.  The absence of a disinfectant residual means that suppression of microbiological growth is much more difficult and the rate of regrowth can be significantly accelerated.  However, does maintaining an adequate disinfectant residual provide enough protection?

  • Flow Meter Advisory: Follow The Money
    Flow Meter Advisory: Follow The Money

    While the majority of household consumers believe that they deserve the full attention of a water system, from a revenue perspective this does not bear out. Though the average home faucet is undoubtedly valued by its drinking water provider, the reality is that the vast majority of drinking water revenue comes from heavy-use commercial and industrial operations.

  • Non-Revenue Water Is A Money Pit. Here’s Your Way Out
    Non-Revenue Water Is A Money Pit. Here’s Your Way Out

    According to the U.S. EPA, $97 billion will be needed over the next two decades to control water loss, comprising 29 percent of the needed upgrade costs in the space overall. The agency estimates that average water loss for a system is 16 percent, with 75 percent of that being recoverable.

  • The Sound Of Progress: How Acoustics Are Advancing Meter Technology
    The Sound Of Progress: How Acoustics Are Advancing Meter Technology

    There is one device that truly encompasses the relationship between drinking water utilities and the consumers who benefit from their services. The water meter represents both the practical aspect of the dynamic (that is, the calculation of how much drinking water reaches a ratepayer and, therefore, what rate they pay), as well as the shared connection that each household has with its provider.

  • AMI And The Zen Of Water Utility Management
    AMI And The Zen Of Water Utility Management

    Drinking water utilities have a lot on their plates. Aside from the inherent technical difficulty of providing a vital service, they have to maintain positive customer relations, contend with increasingly strained budgets, and run operations with as little stress to employees as possible.

    Keep It Clean In The Hot Tub

    With Memorial Day just around the corner, millions of homeowners are pulling the covers off their hot tubs, filling them up and getting ready for summertime relaxation. Hot tubs provide relaxation, ease aches and pains, relax sore muscles, or even — in the case of swim spas — work those muscles instead.

  • Engineered Solution For Bromate Production During Ozonation
    Engineered Solution For Bromate Production During Ozonation

    The design of a utility’s ozone disinfection system often includes a method to minimize the production of regulated oxidation by-products that may form when ozone contacts the water. In regions where water contains a significant concentration of bromide ion (Br¯ ), ozone disinfection systems often minimize bromate (BrO3¯ ) formation by modifying the water chemistry through the addition of chloramines, acid, or other chemical additives.

LAGOON MASTER™ Sludge Activating Aerator LAGOON MASTER™ Sludge Activating Aerator

Recreational ponds, wastewater lagoons, fish grow-out ponds and small, shallow lakes have always exhibited the problem of organic matter collecting on the bottom and eventually becoming polluted. Wastewater lagoons are especially fraught with problems because their purpose is to clean the wastewater to the point that it can be released back into the environment. Over the years many different things have been attempted to assist in degrading the organic matter that builds up in the “sludge” on the bottom of these water bodies.
