Where Stormwater Strategy Meets Practical Guidance

High density polyethylene, commonly referred to as HDPE, has become a widely used material for culvert pipe applications because it is lightweight, corrosion resistant, and relatively easy to install. In roadway and stormwater infrastructure, HDPE culverts are frequently selected as an alternative t…

Open channel outfalls occupy a unique space in stormwater infrastructure. They are simple in appearance, often nothing more than a vegetated swale or gently graded channel, yet when properly designed they function as treatment systems, flow control measures, and in northern climates even snow manage…

Dry weather outfall screening is one of the most effective and defensible tools available to municipal stormwater programs for identifying illicit discharges. Under MS4 permit requirements associated with the Clean Water Act and the NPDES stormwater program, municipalities are required to implement …

Lake George in upstate New York is often called the “Queen of American Lakes” because of its exceptional clarity and scenic setting in the Adirondack Mountains. For generations, residents and visitors have prized its transparent waters, vibrant fisheries, and tourism economy. Yet in rece…

Stormwater culverts come in a wide range of materials, and each type carries a unique combination of strength, lifespan, cost, and installation considerations. Choosing the right material is not a one size fits all choice, because every site presents different soil conditions, hydraulic needs, envir…

A well managed stormwater program depends on accurate and complete information about every outfall in a community. Outfalls are the final discharge points where stormwater leaves the municipal system and enters a stream, lake, wetland, or other receiving water. Because these locations represent the …

When crews encounter contaminated sediments during routine work, or when a concerned homeowner reports a suspicious odor or unusual discharge, the situation calls for immediate but steady action. Stormwater systems often collect materials from a wide range of sources, and although many sediments are…

Opening and entering drainage structures requires a practiced, methodical approach that protects workers from unseen dangers and ensures that every step is guided by awareness, communication, and control. These environments can hold toxic gases, low oxygen levels, and unexpected structural weaknesse…

Constructed wetlands are engineered systems that mimic the natural processes of a real wetland in order to treat stormwater, wastewater, or other polluted runoff. They are intentionally designed and built rather than formed through natural hydrology, but they function in much the same way. Water flo…

A complete and accurate stormwater map is one of the most important responsibilities for any community that operates as a Municipal Separate Storm Sewer System, or MS4. These maps are not created merely to satisfy a regulatory checkbox. They protect waterways, support field crews, reduce liability, …

Several free or very low cost tools can help communities with limited budgets begin mapping or inventorying their stormwater infrastructure. These tools are not full replacements for a dedicated asset management system, but they can give small towns a head start and help them organize information be…

Wetlands are often described as the kidneys of the watershed because they filter, slow, and transform the water that passes through them in ways that protect downstream ecosystems. This comparison is more than a poetic metaphor. It captures the essential truth that wetlands perform quiet but powerfu…
