    Defending Against Saltwater Intrusion

    Are “ghost forests” a sign of things to come? Rising sea levels and superstorm tidal surges are already impacting coastal areas, with rising salinity levels affecting some drinking water sources. Coastal water utilities are not the only ones that have to worry about salinity, however, as high concentrations of winter storm road treatments, gas drilling, and mining can also generate elevated salinity levels in surface water sources.

We do so much where I work that goes well beyond produced water recycling, and it is all extremely important.

  • Are Your Pumps Running As Efficiently As Practical?

    In water and wastewater operations, optimizing energy use plays a huge role in cost efficiency, but how can you know if pumping equipment and other motors are running as efficiently as possible? Analytics systems that interpret performance from a variety of data points — pump curves, run time, flow rates, vibration, temperature, energy consumption, etc. — can quantify pump operation to keep performance efficiency on an upward track.

  • WWTP Air Handling Control Philosophies: Do’s And Don’ts

    Without an appropriate control strategy, even the best wastewater treatment plant (WWTP) equipment can struggle to deliver maximum efficiency. Because energy costs represent up to 60 percent of WWTP plant operating expense, air distribution designs and changing loading (biochemical/biological oxygen demand [BOD]/chemical oxygen demand [COD], ammonia) demands require control strategies designed to adapt to all eventualities efficiently. The following checklists, plus important Do’s and Don’ts, can help in identifying an underperforming control strategy and developing a better one.

    Where’s The Fire? Industrial Uses For Fire Hydrant Meters

    There are many options for ensuring accurate billing of water used at established industrial customer locations. But how do municipalities or businesses keep track of water availability and use for intermittent applications or movable access points? We spoke with McCrometer, Inc.’s Marc Bennett for insight into how water utilities and industries can efficiently track and allocate water use for billing or internal accounting purposes in such ad hoc applications.

  • Total Dissolved Solids: A Matter Of More Than Just Good Taste
    Total Dissolved Solids: A Matter Of More Than Just Good Taste

    Everyone wants good-tasting water, but most water treatment plants (WTPs) are hostages to the composition of their local source water supplies. One of the components involved in taste is total dissolved solids (TDS), which can affect both the acceptability of finished water taste and its likelihood to corrode or clog pipes and fixtures. Here’s how to quantify the problem and what to do about it if it is excessive.
