Managing the quantity and quality of stormwater is termed, “Stormwater Management.” The term Best Management Practice (BMP) or stormwater control measure (SCM) is often used to refer to both structural or engineered control devices and systems (e.g. retention ponds) to treat or store polluted stormwater, as well as operational or procedural practices (e.g. street sweeping). Stormwater management includes both technical and institutional aspects.

When Levi Fuller cut his teeth in the water treatment industry, manning the desalination system on a Navy ship, he didn’t expect some of his more troublesome obstacles on the mainland to be birds and their excrement.

The First Line of Defense: Protecting Inlets and Storm Drains

The First Line of Defense: Protecting Inlets and Storm Drains

In stormwater management for both temporary and post-construction measures, inlet and storm drain protection is one of the first lines of defense. It’s also a measure that often works in combination with other best management practices (BMPs) as part of an overall erosion control or stormwater management program.

Advanced Stormwater Treatment: Dissolved Pollutants

Advanced Stormwater Treatment: Dissolved Pollutants

Did you know that on average in stormwater, 45% of the phosphorus load and ~50% of the metal load (cadmium, copper, zinc, etc.) is present in dissolved form? And unfortunately, most of these dissolved pollutants travel downstream to our receiving water bodies and wildlife untreated (thanks to physical treatments which

Imagine a stormwater management system that provides sedimentation, variable denitrification and oxygen saturation, evapotranspiration, volatilization, and infiltration. Is this the newest high-tech engineered stormwater treatment system? No, it’s the original green infrastructure: the stream channel. In suburban and rural communities in New England and many other parts of the country,

Known for its involvement with banking and auto racing, Charlotte is one of the 10 fastest-growing cities in the US. The city’s 2014 estimated population is nearly 810,000.

Case Study: Industrial Stormwater Treatment at the Port of Tacoma

Case Study: Industrial Stormwater Treatment at the Port of Tacoma

Background

Washington State has some of the most stringent industrial stormwater treatment standards in the United States with exceptionally low benchmark requirements for zinc, copper, and turbidity, also known as total suspended solids (TSS) or sediment.

Within the Port of Tacoma there are three industrial sites that were exceeding their benchmarks

Issues With Clay? No Way!

Issues With Clay? No Way!

This article discusses a novel approach of using a sand lens to convey the stored volume of runoff gradually into the deeper layers of the soil, or to the water table, to overcome some of the design challenges resulting from clayey soils.

Constructed Wetlands for Erosion Control and Stormwater Mitigation

Constructed Wetlands for Erosion Control and Stormwater Mitigation

Many people think of wetlands as smelly, mosquito-ridden nuisances, but healthy wetlands provide habitat for birds, fish, amphibians, bats, and other insects that live on mosquitoes. Wetlands are home to more than one-third of the United States’ threatened and endangered species, according to EPA.
