How Wetlands Act as the Kidneys of the Watershed

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…continue

Maintaining Stormwater Drainage Assets with Modern Management Software

*The screenshots used in this article are from Roadwurx, an asset management software created for road maintenance departments. Managing a town’s stormwater system can quickly become overwhelming when maintenance and inspection records are scattered across clipboards, spreadsheets, or dusty fi…continue

Five Red Flags in Culvert Inspections (and the Tools to Spot Them Fast)

Culverts are among the most overlooked pieces of municipal infrastructure, yet they play a critical role in keeping roads passable and communities safe from flooding. When a culvert fails, the results can be immediate and costly: road washouts, property damage, and emergency closures. That is why re…continue

Culvert Fundamentals: A Practical Overview for Municipal Stormwater Systems

Culverts are enclosed conduits that carry surface water beneath roads, railways, trails, and embankments, allowing drainage and traffic to coexist safely. They form one of the most common, and often most overlooked, structures in municipal stormwater networks. When sized, installed, and maintained c…continue

Understanding MS4 Expectations for a Complete Stormwater Infrastructure Record

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…continue

Protecting Special Value and Sensitive Features During Site Development

Stormwater management succeeds when the landscape itself is considered the first line of defense. Certain parts of that landscape offer outsized benefits or face outsized risks, and thoughtful planning around them is essential. Special Value Features are areas that deliver exceptional stormwater ben…continue

Understanding Brownfields

A brownfield is real property whose reuse or redevelopment is complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. Congress added this definition to the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), recognizing that l…continue

Catch Basins: The First Line of Defense in Municipal Stormwater Management

Every time rain falls on streets and parking lots, it sweeps grit, trash, and pollutants toward the nearest low point. Catch basins sit at those low points, quietly collecting runoff and helping cities keep roadways safe, pipes clear, and receiving waters cleaner. This article explains how catch bas…continue

Precast Underground Vaults: How a Deep Sump Turns Runoff into Cleaner Outfall

What Exactly Is a Precast Underground Vault? A precast vault is a large, reinforced-concrete box or cylinder installed below grade to detain, treat, or both detain and treat stormwater when surface land is scarce. The modules are factory-made for quality control, then craned into an excavated pit an…continue

Restoring Riparian Corridors: Proven Techniques for Healthy Waterways

Riparian corridors, the vegetated strips that border rivers, streams, and lakes, serve as protective edges for both land and water. They filter pollutants, stabilize banks, slow floodwaters, recharge groundwater, and create habitat highways for fish and wildlife. When these corridors are degraded by…continue

Construction Site Runoff Control: Keeping Sediment, Chemicals, and Fines Out of Your Storm Drains

(In the photo above, the silt fence has been improperly installed, as you can see it was placed in loose, already excavated, soil.) Why Construction Runoff Matters A single acre of bare earth can release 10 - 20 times more sediment than the same acre in cropland, and up to 2,000 times more than a fo…continue

Strength in Structure: The Use of Geocells in Modern Drainage Systems

Geocells, also known as cellular confinement systems, have become a trusted solution in the design and maintenance of modern drainage infrastructure. These innovative materials provide structural stability to soils and aggregates, making them particularly useful in applications where erosion control…continue
