12th International Symposium on Managed Aquifer Recharge

Field Excursions

Three possible field excursions to consider for the ISMAR2025:

  1. Cape Flats MAR Scheme
  2. Atlantis MAR Scheme
  3. Langebaan and Elandsfontein MAR Schemes

The Atlantis infiltration scheme

An internationally renowned scheme which has been in operation for over 20 years and has a published field trip which takes participants to various locations in the scheme to witness the infiltration and re-abstraction components.

The Cape Flats MAR scheme

A recently developed injection scheme which was one of the major developments in using groundwater to safeguard the City of Cape Town from future Day Zero events. The scheme was developed during the recent Cape Town drought and participants can be taken to major injection boreholes which are responsible for preventing seawater intrusion into the Cape Flats Aquifer. A short version of this field trip was successfully tested in 2019, with an international MAR workshop in Stellenbosch, which included delegates from South Africa, Botswana and Australia.

The Elandsfontein and Langebaan Road Aquifer MAR schemes

Two neighbouring schemes on the West Coast. One of these was developed to sustainably protect the Langebaan Lagoon from mine pit dewatering and is one of the few African examples of an MAR scheme developed for purely environmental reasons, rather than water supply or security. The other is designed and constructed to help rapidly refill the Saldanha Bay Municipality’s main groundwater supply wellfield after intensive use. A trip to these two schemes was recently fully planned and approved for a delegation from Botswana and Sweden but was cancelled due to Botswana covid travel regulations.
