Plants for Wastewater Land Disposal Areas

Plants that are suitable for planting in moist conditions such as those associated with wastewater land disposal fields need to be selected on the basis of both their tolerance for such moist conditions and for their potential for a high level of growth and high transpiration of moisture in such conditions.

Consideration needs to be given to effects of roots from plants and from trees in particular on wastewater distribution pipe networks/emitter lines in land application systems. Potential for root intrusion / disruption to the pipe system must be considered prior to selection and planting of the plants species.

The following list covers native plant species are considered to be suitable for planting in moist conditions, such as those associated with wastewater disposal fields in Auckland situations.
