Induced bank infiltration

< back

A large variety of schemes has been designed according to site-specific conditions. Collection wells can have either vertical or horizontal screens, depending on the thickness of the aquifer. Where aquifer material beneath a stream is thin, collector wells or infiltration galleries can be installed at the base of the aquifer to allow greater recharge of the aquifer than would otherwise be possible. Some induced bank infiltration schemes have been supplemented with infiltration ponds or recharge shafts to improve water quality and increase recharge. An artificial deposit can be applied to the riverbed, creating a reduced environment to prevent pollution of infiltrated water by organic material.

A special case of induced bank filtration is applied in the Netherlands, where small canals are used to manage and control groundwater levels in low lying parts of the country.
