The following equations assume that infiltration occurs primarily through the base of the facility.
The following equations assume that infiltration occurs primarily through the base of the facility.
They may be applied in all cases, but for some geometries (e.g. where a particularly deep facility is possible and desired) it may be preferred to also account for lateral infiltration.
They may be applied for most shapes and sizes of infiltration facility.
For some geometries (e.g. where a particularly deep facility is both possible and desired), it may be preferred to also account for lateral infiltration.
To calculate the required depth, where the area of the facility is constrained:
