Understanding the Life Expectancy of Corrugated Metal Stormwater Drainage Pipe

June 18, 2026

Stormwater drainage systems are among the most important (and often most overlooked) assets owned by municipalities. Hidden beneath roads, driveways, and rights-of-way, culverts and drainage pipes quietly move stormwater away from infrastructure and help prevent flooding, washouts, and road failures. One of the most common materials used for stormwater conveyance is corrugated metal pipe (CMP). For decades, municipalities have relied on corrugated steel pipe because it is durable, relatively ine…continue

How Stormwater Management Reduces the Need for Road Maintenance

June 10, 2025

Stormwater management is one of the most effective tools municipalities can use to protect their road infrastructure and stretch maintenance budgets. Too often, the relationship between drainage and pavement longevity is overlooked , but the presence of standing water on or near a roadway is one of the primary causes of accelerated road deterioration. This article explains how water affects roads, why good stormwater management is essential, and how investing in drainage can reduce the long-term…continue
