When most people think about stormwater pollution, they think of sediment, nutrients, oils, trash, or road salt. However, heat itself can be a pollutant. Thermal pollution occurs when stormwater runoff becomes significantly warmer than the natural receiving waters it eventually enters. Elevated wate…

Most storm drain inlets quietly collect and convey runoff without attracting much attention from the public. To many residents, a storm drain is simply another opening in the curb or grate in the pavement. What many people do not realize, however, is that storm drains in most municipalities discharg…

In stormwater management, some of the most serious failures begin as subtle warning signs that are easy to overlook unless someone is paying close attention. A cross culvert that appears nearly full on a dry day, with no recent rainfall to explain elevated water levels, is one of those warning signs…

Across towns and counties, road departments replace cross culverts every day. The motivation is usually sound. Aging pipes fail without warning, and a collapse beneath the roadway can create a serious safety hazard, not to mention an expensive emergency repair. Proactive replacement is responsible a…

Street sweeping rarely gets much attention. It is slow, repetitive work, often done in the early morning hours, and the equipment itself can be temperamental and expensive to maintain. Sweepers are subject to constant wear, from abrasive debris, dust, and the mechanical strain of brushes, conveyors,…

Infiltration-based best management practices, or BMPs, are designed to capture, store, and gradually infiltrate stormwater into the ground. These systems, which include bioretention basins, infiltration trenches, dry wells, and porous pavement systems, are particularly vulnerable during and immediat…

Fire hydrant flushing is a common and often necessary practice for maintaining water distribution systems. Municipalities flush hydrants to remove sediment, verify system performance, and ensure adequate flow for firefighting. While these objectives are important, the practice can carry a range of u…

Municipal Separate Storm Sewer System programs, commonly referred to as MS4 programs, are often viewed as regulatory obligations, while stormwater asset management is treated as an operational necessity. In reality, these two efforts are deeply interconnected. When properly aligned, a strong asset m…

Is a Catch Basin Appropriate Here? Before a catch basin is installed, it is important to step back and ask a simple but often overlooked question, what purpose is it actually going to serve at this location? Catch basins are frequently installed out of habit or because “there has always been o…

Culverts are often out of sight and, as a result, out of mind, until they fail. When they do fail, the consequences can range from nuisance flooding to full roadway washouts. One of the most overlooked factors in culvert performance is vegetation management. Too little control can obstruct flow and …

Municipal road crews are on the front lines of stormwater management whether they realize it or not. Every ditch they shape, every culvert they install, and every roadside repair they complete has a direct impact on how water moves across the landscape. Yet in many public works departments, stormwat…

Municipal stormwater systems tend to operate quietly in the background, doing their job year after year with little attention. Pipes carry flows, culverts pass streams beneath roads, catch basins collect runoff, and ditches guide water away from infrastructure. Because these systems are largely out …
