Changes

The diverse range of managed aquifer recharge (MAR) schemes illustrates how the economics of different adaptation options can vary considerably. Low technology schemes such as [[Controlled_flooding_/_Spreading_basins|controlled flooding / spreading basins]] and [[sand dam]]s are less expensive (about US$10 to US$50 per ML, ignoring pipeline costs) than, for example, borehole injection methods (in the order of US$100 to US$1,000 per ML). Consequently [[Wells,_shafts,_and_boreholes|borehole injection methods ]] are often less viable, particularly for agricultural purposes, although in some areas may be suitable for urban and domestic water use. This provides an example where the economic feasibility is driven not only by cost, but also other considerations such as the scale of the scheme and the end-user of the water resource.
