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,…

Municipal Separate Storm Sewer System, or MS4, compliance is built on documentation. Whether you are demonstrating outfall inspections, tracking illicit discharge investigations, or verifying maintenance activities, a well-organized photo-log can be one of the most effective and defensible tools in …

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…

Managing outfalls as assets rather than afterthoughts represents a fundamental shift in how municipalities approach stormwater infrastructure. For many communities, outfalls are only addressed when something goes wrong, such as erosion, structural failure, or a visible discharge issue. By that point…

Stormwater asset management is one of those concepts that sounds technical and abstract, yet at its core it is simply about knowing what you own, understanding its condition, and making informed decisions before problems turn into emergencies.

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 …

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, …

Field inspections of catch basins, manholes, culverts, and outfalls form the foundation of responsible stormwater management. These routine checks give municipalities an ongoing view of the condition of their drainage network and allow crews to identify issues long before they become flooding hazard…

Municipal Separate Storm Sewer System (MS4) permits rest on a simple idea: you cannot manage what you have not first documented. The Environmental Protection Agency (EPA) defines an MS4 as any publicly owned system of drains, pipes, ditches, or similar conveyances that carries runoff to waters of th…
