Infiltration trenches are an ideal technology for installing below any type of landscape with requirements to infiltrate excess stormwater while safely conveying excess flows during major storm events. Components include: reservoir [[aggregates| aggregate]] to store runoff water, perforated pipe to deliver and distribute flow to the trench, [[geotextile]], [[Inlets|inlet structures]], [[Pretreatment| pretreatment devices or features]] and [[Wells| monitoring wells]] to track drainage performance of the facility over its operating lifespan. <br>

Optional components include a flow restrictor to control the release rate of the facility, and surface drains to safely convey flows in excess of the storage capacity of the design.<br>
