Understanding Drywells in Municipal Stormwater Management

February 23, 2025

Municipal stormwater management is a crucial aspect of urban planning, ensuring that rainwater and runoff are effectively controlled to prevent flooding, erosion, and water pollution. One of the methods employed in stormwater management is the use of drywells. These underground structures help manage stormwater by facilitating groundwater recharge and reducing surface runoff. What is a Drywell? A drywell is a subsurface drainage system designed to collect and disperse stormwater into the surroun…continue

How Stormwater Drainage Affects the Stability of a Paved Road

February 22, 2025

Proper stormwater drainage is a crucial factor in maintaining the longevity and stability of paved roads. When water is not effectively managed, it can lead to a range of structural problems, increasing maintenance costs and reducing the lifespan of the pavement. In this blog post, we’ll explore the impact of stormwater drainage on road stability and the best practices for mitigating these issues. The Impact of Poor Stormwater Drainage on Road Stability Water Infiltration and Pavement Dete…continue

Kinds of Highway Drainage

December 24, 2018

Roadway Roadway drainage is the control of water within the roadway including moving water off the surface of the roadway, and removing excess subsurface water infiltrating the roadway base and subgrade. We need to intercept and direct excess water away before it gets in to the roadway and use materials and techniques to allow excess moisture in the roadway to drain away. Roadside Roadside drainage is the controlling of water beyond the roadway, including water coming from the roadway surface an…continue

Understanding Water Movement

December 24, 2018

Hydrologic Cycle Rain and snow falling on the ground will run overland or soak into the ground. Eventually all the runoff will reach lakes, streams, or the ocean where the water will evaporate and start the cycle all over again Water Movement Around Roads When maintaining and building roads and streets, we must be concerned with water flowing around them. Figure 2 shows a conceptual drainage system and how watermay enter a road. Water may enter roadways through “cracks and surface defects&…continue
