• Peak Wet Weather Flow Management — A Slow And Painful Process

    The water and wastewater industry is not like most businesses. Our industry is driven by many factors, including environmentalist concerns, federal and state regulatory water quality requirements, and utilities being good stewards of our waterways and providing clean water for drinking and recreational use. We have accomplished a lot of great work to clean up our waterways and provide safe water since the Clean Water Act (CWA) was first passed.

  • MWRD Completes Another Link In Its Tunnel And Reservoir Plan

    Despite a frightening global coronavirus pandemic threatening the health and safety of workers everywhere, construction is moving forward.

  • Cost-Effective Assessment Of Infiltration At Green Infrastructure Stormwater Management Sites

    As signs of urban sprawl continue across the United States, so do the impacts of urban space on environmental quality and natural resources including our landscape. Urban development often leads to the removal of vegetation and soil, and replacing them with large stretches of impervious surfaces like concrete and asphalt. This disturbance is closely connected to deteriorating urban water quality and enhanced flood risks resulting from stormwater runoff.

  • Green Infrastructure: Gateway Into Sustainability For Cities

    Cities across the nation face severe challenges that pose a risk to the health of communities and their rivers. Unlike natural environments, the vast quantity of asphalt surfaces found in urban areas prevents rainfall from infiltrating into the ground. Creating green spaces within a city landscape allows rain easy access into the ground, decreasing the amount of stormwater runoff that enters our water sources.

  • EPA Partners With Cincy’s Cooper Creek Collaborative To Improve Water Quality

    As cities grow, meadows and forests become buildings and pavement — a change that can impact our streams, rivers, lakes, and groundwater, also known as urban hydrologic alteration. Most buildings and pavement are impervious surfaces, which means they cannot absorb rainwater. As water journeys across these surfaces to collection points, it can collect various contaminants, such as fertilizer, bacteria, motor oil, lawn chemicals, and pet waste.

  • The Future Of Collection Systems

    As real-time monitoring continues to infiltrate the water industry, it’s time to apply such instrumentation to detect the other type of infiltration — along with inflow, snow and ice melt, etc.

  • A Comprehensive Approach: Flood Protection And Improved Water Quality For Denver Communities

    When confronted with resiliency issues, Denver took a multifaceted approach that showcases the city’s vision along with its technical know-how.

  • Considering Bonds To Fund Green And Hybrid Infrastructure

    At the Stockholm World Water Week 2019, the need for new water infrastructure was a theme running through the conference agenda. As extreme weather events occur now with alarming regularity, the question is material for every water user, not the least of which are utilities and local governments.

  • More Frequent And Intense Tropical Storms Mean Less Recovery Time For The World's Coastlines

    Tropical cyclones — storms that bring strong, rotating winds and rain, and which can intensify into hurricanes or typhoons — affect coastal regions around the world. Our research team, centered at the University of North Carolina’s Institute of Marine Sciences, has analyzed a 120-year record of tropical cyclones affecting coastal North Carolina, and found that six of the seven wettest storms over this time period occurred in the past two decades.

  • Another Summer Of Flooding Should Be A Wake-Up Call To Redesign Our Communities

    Hurricane Dorian has left a trail of devastation over the last few days, but an onslaught of destructive floods have hit communities all across the country this summer. From small towns in the Midwest and Southeast to large cities like Washington and New York, torrential rains have inundated homes, cut power, and disrupted lives.


  • Clara Filter – High-Flow, High-Load Stormwater Filtration

    Is your industrial facility close to the benchmarks?  Do you want an added measure of certainty to be in compliance with your industrial general stormwater permit?  Is your industrial facility unpaved or does it have broken pavement that is affecting your stormwater quality?  Does your permit require corrective actions?  Or is the facility large and you’d like to incorporate end-of-pipe stormwater treatment that doesn’t break the bank?  

  • OpenFlows SewerOPS

    Wastewater utilities face difficult operational challenges when timely decisions are needed for events associated with a range of conditions, from normal operation to sewer overflows, blockages, and network power outages. You not only need a good sense of what is happening in your network right now, but also the ability to accurately predict what is about to happen, and how to respond to achieve the best possible outcome.

  • AquaStorm™ Cloth Media Filter

    The AquaStorm™ cloth media filtration system is designed as an economical and efficient solution for the treatment of wet weather applications. This system utilizes a disk configuration and the exclusive OptiFiber PF-14® pile cloth filtration media to effectively filter high solids waste streams with and without the use of chemicals as determined necessary for application-specific water quality. This system is ideal for wet weather applications due to its proven removal efficiencies and high quality effluent, even under varying influent conditions.

  • Wastewater Collection System That Causes Less Disruption To Communities

    Cost-Effective, Environmentally Sound

    Orenco Sewer™ (effluent-only sewer) is a cost-effective, environmentally sound wastewater collection system. With an Orenco Sewer, raw sewage flows from a house or business to a watertight underground tank. Only the filtered liquid portion is discharged (by either pump or gravity) to shallow, small-diameter collection lines that follow the contour of the land. Solids remain in the underground tank for passive, natural treatment and only need to be pumped every 10 to 12 years (depending on the number of residents and the tank volume).

    Orenco Sewers take significantly less time to install than conventional sewers. And in an Orenco Sewer, material and excavation costs are reduced because the inexpensive collection lines are shallowly buried just below the frost line. Because only liquid is being pumped, system designers don’t need to worry about minimum velocities and associated grades. This simpler installation process causes less disruption to communities and allows businesses to operate normally during construction.

  • StormTEE Litter Control Screens

    StormTEE® litter control screens are ideally suited for the simple, affordable removal of trash/litter/debris and associated pollutants from stormwater flows in a variety of applications. These patented, self-cleaning deflector screens can be used alone or in conjunction with other devices, including the combination fine- particle separation and oil/water coalescing modular unit as part of a complete BioSTORM® stormwater treatment system. StormTEE® deflector screens are easy to install in both new construction projects and is perfect for retrofits too.
