Potable Water Supply

Managed aquifer recharge (MAR) can improve water security by using aquifers to store water when it is abundant until required for future use and can increase the use of urban stormwater and treated wastewater to reduce the demand on traditional surface water and groundwater supplies. Recently, two Australian examples were showcased internationally as sustainable and economic MAR: Perth’s groundwater replenishment scheme (GWRS) with recycled water to increase security of urban water supply and a multi-site urban stormwater MAR scheme for suburban non-potable water supply in Salisbury, Adelaide. This paper provides a synopsis of these Australian exemplars of sustainable and economic MAR.

Santos is producing natural gas and expanding its CSG operations in the Surat and Bowen Basins, Queensland for the Gladstone Liquefied Natural Gas (GLNG) project. During the project, it has been estimated that a total of ∼340 GL of associated water could be produced from gas extraction in three CSG fields. Beneficial re-use of this water is a high priority and one option involves treating the water and re-injecting it into the water supply aquifers in the Great Artesian Basin. In the past 100 years, groundwater pressures in the Gubberamunda Sandstone aquifer, Roma’s main town water supply, have declined more than 80 m and groundwater demand for the town water supply is now more than 5 ML/day. This demand, coupled with forecast droughts in modelled climate change scenarios, provides an impetus for the beneficial re-use of treated produced water. To assess the feasibility of the aquifer for managed aquifer recharge (MAR), a risk-based framework consistent with the Australian Guidelines for Water Recycling: Managed Aquifer Recharge was applied. A series of assessment stages designed to protect human health and the environment were undertaken, each allowing a decision point for investment. To date, a MAR well-field has been developed and numerous hydraulic tests have been undertaken along with laboratory/desktop evaluation of the geochemical compatibility of the injected water with the water and sediment of the target aquifer. An injection trial in Q4 2011 will evaluate the aquifer storage potential and confirm numerical/laboratory studies related to hydraulics and water quality compatibility.

Alternative Water

The Island of Gotland (3000 km2), east of mainland Sweden, suffers from insufficient water availability each summer. Thin soils and lack of coherent reservoirs in the sedimentary bedrock lead to limited reservoir capacity. The feasibility of Managed Aquifer Recharge (MAR) is explored by identifying suitable areas and estimating their possible contribution to an increased water availability. MAR is compared to alternative water management measures, e.g., increased groundwater abstraction, in terms of costs and water availability potential. Results from GIS analyses of infiltration areas and groundwater storage, respectively proximity to surface water sources and surface water storage were classified into three categories of MAR suitability. An area of ca 7700 ha (2.5% of Gotland) was found to have good local conditions for MAR and an area of ca 22,700 ha (7.5% of Gotland) was found to have moderate local conditions for MAR. These results reveal the MAR potential on Gotland. The water supply potential of MAR in existing well fields was estimated to be about 35% of the forecasted drinking water supply and 7% of the total water demand gap in year 2045. It is similar in costs and water supply potential to increased surface water extraction.

The World

Managed aquifer recharge is a widespread and growing practice. In addition, using recycled water for groundwater recharge and water supply continues to grow as water resources are increasingly strained by population growth and climate change. Through a series of examples from around the world, the chapter illustrates the value as well as limitations of managed aquifer recharge and recycled water.
