Practices which infiltrate surface runoff through an engineered soil or [[filter media]], and discharge through an [[underdrain]] perforated pipe include [[stormwater planters]] and partial- and no-filtration forms of [[bioretention]].

The maximum flow rate from the BMP may be limited by the hydraulic conductivity of the medium, or by the properties of the perforated [[pipe]]. See [[Flow through pipe]] page for guidance on estimating the maximum flow rate of a perforated pipe.
