Infiltration trenches are an ideal technology for installing below any type of landscape with requirements to infiltrate excess stormwater whilst conveying excess.  Components include: layers of coarse [[aggregates]] (to bed the pipe, store and redistribute water), [[underdrain|perforated pipe or underdrains]] and [[geotextile]]. <br>

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: layers of coarse [[aggregates]] (to bed the pipe, store and redistribute water), [[underdrain|perforated pipe or underdrains]] and [[geotextile]]. <br>

Design and operation and maintenance program assumptions used to generate cost estimates are based on tool default values and the following STEP recommendations:
