Special Issue Information

Dear Colleagues,

Managed Aquifer Recharge (MAR) and water banking is a growing field of endeavor in water resources management. It is used to buffer against drought, changing climate and demand growth by making use of  excess surface water supplies and recycled waters. Institutions that perform the necessary permitting and monitoring are required so that a region’s groundwater quantity and/or quality management can be furthered through MAR. While several jurisdictions have frameworks in place, many do not. Lack of an enabling policy and governance frameworks limits the realization of MAR benefits. Limited analysis of the economics of MAR has also inhibited development of and investment in MAR programs. This special edition of the ‘Water’ Journal is designed to fill the analysis void by including papers on the policy and economics of MAR and water banking. The information and analyses are intended to contribute to the development and implementation of effective MAR programs.

This paper explores the potential economic benefits of water banking in aquifers to meet drought and emergency supplies for cities where population is growing and changing climate has reduced the availability of water. A simplified case study based on the city of Perth, Australia was used to estimate the savings that could be achieved by water banking. Scenarios for investment in seawater desalination plants and groundwater replenishment were considered over a 20 year period of growing demand, using a Monte Carlo analysis that embedded the Markov model. An optimisation algorithm identified the minimum cost solutions that met specified criteria for supply reliability. The impact of depreciation of recharge credits was also explored. The results revealed savings of more than A$1B (~US$1B) or 37% to 33% in supply augmentation costs by including water banking in aquifers for 95% and 99.5% reliability of supply respectively. When the hypothetically assumed recharge credit depreciation rate was increased from 1% p.a. to 10% p.a. savings were still 33% to 31% for the same reliabilities. These preliminary results show that water banking in aquifers has potential to offer a highly attractive solution for efficiently increasing the security of urban water supplies where aquifers are suitable.
