  • In California, Come Rain Or Shine, Upfront Efficiency Is Always In Style
    In California, Come Rain Or Shine, Upfront Efficiency Is Always In Style

    Caught between a withering drought and floods from winter storms, California faces the worst of both worlds—dealing with scarcity as well as stormwater.  America, and much of the world, is watching to see how this trendsetting state handles those challenges.  After generations of setting America’s style, from cowboys to Beatniks to Beach Boys to Silicon Valley billionaires, California can set perhaps its most important trend yet—it can lead the way to a more water-efficient America.  It has to.  The good news is that it can.

    WWEMA Window: Tackling Today’s Top Challenges

    On September 24, 2013, the Water and Wastewater Equipment Manufacturers Association (WWEMA) held its annual President’s Council at the Chicago O’Hare International Airport. This is an informative one-day event where top executives of WWEMA-member companies get together to share and discuss industry trends, national and international economic news, and upcoming regulatory issues. This was my fifth year attending this event. Each year the insight that is shared is amazing, and 2013 was no exception. By Frank J. Rebori, president of Smith & Loveless, Inc. and vice chairman of WWEMA

    Cooling Water Intake Decisions Are Heating Up

    Now that the U.S. Environmental Protection Agency (EPA) has issued its rule for cooling water intakes under Section 316(b) of the Clean Water Act, the race is on for more than 600 power plants and manufacturing facilities to comply.  Right now, there is probably no better example in the water industry of how carefully choosing among compliance options can lead to millions of dollars in cost savings.

    Howard County, Maryland Sets The Pace In Restoring Chesapeake Bay Ecosystem

    Howard County, Maryland, Bureau of Utilities recently completed the $92-million Addition No. 7 project at the Little Patuxent Water Reclamation Plant (LPWRP) to improve the quality of the plant’s effluent discharge and to reduce harmful nutrients reaching Chesapeake Bay. The project’s various increments took over five years to complete and incorporated innovative design solutions and state-of-the-art technologies for denitrification, aeration and disinfection. The project presents a model for Maryland’s 66 largest wastewater treatment plants and possibly procurement of municipal facilities elsewhere facing increasingly stringent regulatory changes.

  • WWEMA Window: Bridging The Optimization Gap
    WWEMA Window: Bridging The Optimization Gap

    The term “optimization” is becoming increasingly ubiquitous in our industry. Search almost any conference program, read through a trade journal, or sit in an annual planning meeting and you are likely to see or hear the word. However, as it gains popularity, optimization may be generating more questions than answers. Utilities often ask what optimization means and how to get started. For those that have already made changes, they may be asking if their utility is fully optimized.  By Kurt Tyler, Hach Company

  • Troubleshooting Nitrification And Denitrification In Wastewater
    Troubleshooting Nitrification And Denitrification In Wastewater

    The proper tools are essential to fixing any problem. Over the years, Ohio EPA’s Compliance Assistance Unit (CAU) has helped dozens of water resource recovery facilities (WRRF) get back into and maintain compliance with NPDES discharge permits. Their field toolkit has included an assortment of batch sampling kits and handheld instruments. Each tool had its place but each also had limitations and, as a result, the compliance puzzle often was missing important pieces. Increasingly, as nutrient limits were incorporated into discharge permits, the missing piece was characterizing the dynamics of nitrification and denitrification. By Patrick Higgins

    Flood Improvement And LID Modeling Using XP‐SWMM

    Over the years, a number of severe storms have impacted the Harris Gully watershed, including Tropical Storm Allison, which resulted in $5 billion in damages in 2001. Inundation was especially severe at the downstream portions of Harris Gully, where Rice University and the Texas Medical Center are located. A1D/2D hydraulic model (XPSWMM) was instrumental in simulating and evaluating the effects of a proposed drainage alternative.

  • A New, Cost-Efficient Way To De-Sludge Your Lagoon
    A New, Cost-Efficient Way To De-Sludge Your Lagoon

    Most small towns, all over the world, utilize lagoons for treating their wastewater. Many rural industries also utilize lagoons for storm-water and wastewater treatment. While industrial plants may be able to pay for activated sludge treatment of one design or another, small municipalities simply do not have a choice in treating their small populations’ wastes. If the town’s population is not growing, the costs imposed for maintaining a wastewater plant are just not viable on a rural community’s, often, declining budget. The ongoing costs of trained personnel, electricity, and plant maintenance for a wastewater plant is just too high for communities with limited budgets. By Jim Dartez

    The Basics: Keeping Our Water Clean Requires Monitoring

    Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.
