  • Prioritizing Alarm Responses For Better Workforce Management
    Prioritizing Alarm Responses For Better Workforce Management

    While the laws of physics and chemistry have not changed, the ways that water and wastewater treatment plants (WTPs/WWTPs) are being forced to deal with them over the past few decades certainly have.  This ranges from increased focus on disinfection byproducts (DBPs), to tighter turbidity standards for charting Cryptosporidium removal, to emerging challenges with harmful algal blooms (HABs) and per- and polyfluoroalkyl substances (PFASs). Even when plant throughput volume stays the same, the demands on plant operations personnel continue to increase. Here’s how evolving toward better workforce management processes can help.

  • Coping With Mixed-Source Water Quality And Corrosion Challenges
    Coping With Mixed-Source Water Quality And Corrosion Challenges

    When it becomes necessary to expand or blend water supply sources, variety is not necessarily the spice of life.

The Hampton Roads Sanitation District responded to these issues by using groundwater augmentation as a way to recharge the aquifer, prevent saltwater intrusion, and potentially increase ground elevation.

  • The Data Influx: Transforming Data Overload Into Business Insights

    “We have too much data” is the refrain we continually hear from water utilities. It’s no surprise that managing data from multiple sources and turning it into business insights presents a daunting challenge; however, data influx does not have to be a burden. When managed well, there’s no such thing as too much data, especially if your business is implementing a big data strategy — a topic that has implications and reach beyond the scope of this paper.

  • AMI Cloud Solutions No Longer Considered Pie-In-The-Sky

    By now, most of the utilities managing the 80 percent of U.S. water meters not yet capitalizing on advanced metering infrastructure (AMI) have heard about the advantages offered by the 20 percent of utilities that are. Unfortunately, utilities large and small still cite a variety of reasons delaying their step up to AMI productivity — including smart meter installation costs, lack of in-house expertise, and capital budgets for IT support.
