TRANSPORTATION DRAINAGE Drainage systems that keep communities moving.

Urbanization has dramatically altered our natural water cycle. As buildings, roadways, pavement and underground piping replace open land, hydrologic patterns are disrupted. Water cycle disruption accelerates stream flows, halts groundwater recharge and pollutes runoff. This issue is especially glaring in transportation infrastructure, where unmanaged stormwater can compromise safety, degrade pavement and overwhelm local waterways. WSP addresses these challenges with our multidisciplinary approach. We plan, design and construct a full range of stormwater transportation drainage systems needed to protect the environment. Our team integrates expansive expertise with local knowledge to deliver solutions that are both technically sound and contextually appropriate. WSP utilizes our technical expertise in hydrology and hydraulics of structures including bridges, culverts, urban drainage and storm drains, and erosion and scour mitigation with our goal of ensuring economic design, constructability

and sustainability of drainage structures. We design and implement systems that include catch basins and inlets to collect roadway runoff, storm drains and culverts to convey flow, and detention or retention basins to manage peak volumes. Our teams also incorporate green infrastructure (bioswales, permeable pavements, and rain gardens) to naturally filter and absorb runoff, improving water quality and reducing downstream impacts. WSP’s stormwater drainage solutions are built for safety and durability. They safeguard our communities by preventing hydroplaning and erosion, as well as extending the lifespan of transportation structures. Our experts are well-versed in regulations and compliance, consistently meeting regulatory requirements such as the National Pollutant Discharge Elimination System. Most importantly, our solutions are designed with tomorrow in mind— ready to adapt to extreme weather events or increased urbanization.
