Permeable Conveyance Systems

Permeable conveyance systems move runoff water slowly towards a receiving watercourse allowing storage, filtering and some loss of runoff water through evaporation and infiltration before it reaches the discharge point. The main types of permeable conveyance systems are underground systems such as filter drains (or French drains) and surface water swales.
