Urban Stormwater Research Takes Root at CSU Spur: Water TAP's Bioretention Pilot Project
A real-world experiment in Denver is helping shape greener, cleaner stormwater solutions for Colorado communities
Purpose
To evaluate the performance of urban bioretention systems using real stormwater runoff, with the goal of optimizing green infrastructure design for Colorado’s semi-arid climate and demonstrating how stormwater can be used as a fit-for-purpose alternative to potable water for landscape irrigation.
Description
At CSU Spur campus, researchers are leading a four-year study to improve the design and performance of bioretention systems used in urban streetscapes. The project features custom-built test plots that mimic streetside planters found across the Denver metro area, complete with region-specific and experimental media mixtures, vegetation, and stormwater-fed irrigation systems. Using real stormwater runoff collected onsite, researchers are monitoring water quality, flow, and plant health to optimize how these systems function in Colorado’s semi-arid climate.
Impact
Findings will guide more effective, low-maintenance green infrastructure that improves urban water quality, reduces irrigation needs, and supports healthier streetscapes. The research delivers practical insights for planners and engineers seeking resilient, climate-adapted stormwater solutions.
