water abstracted will be used for drinking, unless you have the ability to apply an appropriate filter.
 {{procontable | proborder="1" cellpadding="5" cellspacing="0" align="center"|-! width="50%" style="background:#efefef;" | Advantages! style="background:#ffdead;" | Disadvantages|-| valign="top" | - Can assist recharge of shallow wells. Allows groundwater aquifers to be treated as massive storage tanks where in times of surplus, the aquifer can be recharged while in times of drought the water can be extracted. One example of this is the “water bank” concept for Windhoek’s water supply in Namibia. <br>
- Can reduce salinity in groundwater <br>
- Low cost and simplicity enables it to be replicable by users without donor funds<br>
| convalign= "top" | - Water quality requirements of recharge water are high <br>
- A good understanding of the hydrogeology of the aquifer is needed<br>
- Technology needed to construct these structures can be quite complex, requiring engineering skills.<br>|}}
