Stormwater Management Resources

71. PFOA/PFOS Stormwater Treatment 5/11/2021

    Following several years of piloting ion exchange resin for the removal of perfluorinated compounds, CKS Engineers needed to design and construct a full-scale system to treat the former military base stormwater runoff before entering Neshaminy Creek.

72. Assessing Impacts Of Green Infrastructure On Groundwater Quality 4/21/2021

    Typical stormwater management design – pipes, sewers, and collection systems – is intended to transport rainwater runoff to sewage treatment plants or surface water bodies, since the impervious surfaces of streets and cityscapes do not allow rainwater to soak into the ground. While this design is intended to reduce flooding of streets and buildings, it can actually increase the risk of flooding and erosion when large volumes of stormwater overwhelms the treatment plants and directly enter surface waters. When the rainwater does not soak into the ground where it falls, the underground storage volume of water decreases, and the underground water supply is not replenished. Green Infrastructure (GI) is designed to mimic natural systems by allowing more rainwater to soak into the ground rather than be transported away. GI is designed to reduce stress on wastewater systems, decrease sewer overflows, and improve watershed health.

73. How To Do Level Monitoring Better 4/16/2021

    Existing level monitoring, usually for combined sewer overflow (CSO) or event duration monitoring (EDM) purposes has been in regular use in the U.K. for over a decade, but the equipment hasn’t changed much in that time. With the current technology comes limitations. So, the question Dave Walker, co-founder and commercial director at wastewater monitoring specialists Detectronic, has been asking is: How can we do level monitoring better for the benefit of water companies, their customers, and the environment?

74. Looking Forward: How Digital Solutions Can Save Us From Future Disasters 3/18/2021

    Infrastructure rarely makes headlines, but the severe devastation in Texas requires a blunt conversation about aging infrastructure in the U.S. In a strange coincidence, shortly after news and images from Texas shocked the world, ASCE published its 2021 Infrastructure Report Card highlighting the decrepit state of the nation’s infrastructure, and, for the first time, including a report card for stormwater management.

75. Why Businesses Could (And Should) Utilize Green Roofs To Become More Resilient 3/8/2021

    Green roofs aren’t just for the most progressive, environmentally focused organizations, though early practitioners should be lauded for leading the charge. The stormwater solution also saves money, protects assets, and improves workplaces — all reasons to be broadly implemented.

76. Partnering For Equity And Clean Water 2/22/2021

    It was the evening of October 1, 2012 at the Rick McDevitt Community Center in Four Corners Park. The cinder block walled room was filled with community members interested in learning about the city’s plans for stopping the flooding and combined sewer spills in their neighborhood. Just three months prior, a 25-year storm delivering 3.5 inches of rain in just four hours flooded streets and filled basements and backyards with toilet paper and sewage. It was then the Mayor promised a plan within 30 days for addressing the problem.

77. Floods Will Always Come, But We Can Build Better To Prepare 2/12/2021

    As the climate changes, floods and extreme rainfall events will become more intense. In many cases, the most disadvantaged people are at highest risk from floods and least able to bounce back when their homes and businesses are inundated. I saw that dynamic first-hand when I lived through Hurricane Katrina in New Orleans. Much of my work in its aftermath focused on finding new ways to allow the city to better absorb water, reducing flood risk and easing pressure on drainage systems.

78. Flood Forecasting: The Original Operational Water Digital Twin 2/11/2021

    Flooding can be an essential part of the economy — so much agriculture depends on the nutrients that flood brings. However, most of us know flooding for the damage, disruption, and of course loss of life, that it brings.

79. Beyond A Project Model: Why You Need A Sewer / Storm Master Database 1/21/2021

    The status quo of modeling is ready for change. For years, engineer and planning teams have used hydraulic and hydrologic (H&H) models to adjust and plan for long term changes to the system. Many times, when the core project of the model is completed the model is left without updates for long periods of time.

80. In The Green: Embracing Innovation To Finance The New Localized Water Infrastructure 1/13/2021

    An uncommon financing model is proving effective at resolving an all-too-common issue throughout the U.S. — underfunded water infrastructure needs.
