Inflitration practices are a key element of runoff reduction, but they require careful design and testing to work properly. CSN has developed design specifications that outline three scales for infiltration: micro-infiltration, small-scale infitration and conventional infiltration. The spec also outlines a process for evaluating whether the proposed site will be a designated stormwater hotspot where infiltration is restricted or prohibited.
On this page you can also find information on visual indicators to inspect and maintain infiltration practices and several webcasts that we have done on the subject. Enjoy!
