Culvert Material Choices and Their Best Uses in Modern Stormwater Systems

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…continue

Stormwater Outfall Data Requirements, What Must Be Recorded and Why It Matters

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 …continue

Safe Entry Starts Before the Hatch, A Step by Step Guide to Confined Space Awareness and Structure Assessment

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…continue

What Are Constructed Wetlands?

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…continue

What Every MS4 Must Map, and Why It Matters for Waterway Protection

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, …continue

Free Mapping Tools for Communities with Limited Budgets

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…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

Slip-Lining Culvert Pipes

When a culvert begins to corrode, crack, or separate at the joints, engineers and highway departments often face a choice between excavating the old pipe and installing a new one or rehabilitating the existing structure in place. Slip-lining is the most widely used trenchless rehabilitation techniqu…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 and Utilizing Natural Waterways in Stormwater Management Planning

Natural streams, creeks, and drainage swales evolved to carry rainfall runoff long before culverts and pipes existed, and they remain one of the most efficient, resilient, and cost-effective elements in any municipal stormwater network. When a community plans for development or retrofit, treating th…continue
