usually when talking about recharge into groundwater aquafires, we are encountered with the urban recharge which can be explained;
Urban Recharge
The use of water in metropolitan areas releases significant volumes of water indirectly from the urban infrastructure and directly from some water uses, such as parkland and garden irrigation.
This water infiltrates into the superficial and shallow aquifer system, that together comprise a much greater contribution of recharge water to the aquifers in urban areas than the natural recharge from rainfall and run-off.
The urban recharge contributions come from:
- Natural recharge (direct recharge from rainfall)
- Urban run-off (run-off from pavements, roads and roofs directed to infiltration basins, roadsides, soakways etc.)
- Leakage from TSE and Drinking Water pressurized mains
- Leakage or groundwater capture from the foul sewer network
- Septic tank leakage (or groundwater capture from tank emptying)
- Municipal and agricultural irrigation return
- Domestic (garden irrigation return, car washing, etc.)
