• 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.

  • 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.

  • 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.

  • 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.

  • Reversing The Process: Urban Planners Should Focus On Water First

    With concerns over stormwater management escalating, green stormwater infrastructure (GSI) offers a multi-benefit, cost-effective solution.

  • Separate Ways: Examining The Stormwater Needs Gap

    The Water Environment Federation’s (WEF) Stormwater Institute (SWI) reports on challenges and the annual funding gap for the municipal separate storm sewer system (MS4) sector.

  • EPA Stream Restoration Research Supports Chesapeake Bay Recovery

    Fifty-one billion gallons. That’s the average amount of water flowing into Chesapeake Bay on a daily basis. And as all that water seeps, flows, and cascades across the watershed before it spills out into the Bay — the nation’s largest estuary — it picks up signature characteristics of where it has been.


  • 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.

  • Orenco Sewer

    Wastewater Collection System

    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.

  • Pavement Filtration For Onsite Rainwater Management

    As a Sustainable Drainage System (SuDS), the d-Rain Joint™ is a simple, low-cost, and robust onsite storm water management alternative compared to other permeable, pervious surface options and can be used wherever a permeable, pervious driveway, parking lot, street or walkway is needed. The use of traditional pavement with the d-Rain Joint™ provides both permeability AND filtration at a lower installed cost!  


Use a sewer network model to test variations in operational strategy, tactics, and emergency protocols in a risk-free way. Identify safe, inexpensive options to improve the resilience and daily management of sewer networks. For example, quickly determine the amount of bypass pumping required in the event of a sewer blockage.
