Our transcription: Part of the success of the Orange County Water District can be traced to measures taken to recharge the local aquifer.
One of the ways the Orange County Water District manages the groundwater basin is by insuring that we put as much water into the ground as we take out through a series of extraction wells.
This is done primarily through our recharge facilities, much like the one shown in the background here.
These recharge basins, or facilities, consist primarily of old gravel pits and also what's in the channel.
The off channel, or old gravel pits, capture water from the river and divert it into these basins, where it effectively percolates into the groundwater.
All of these basins are underlined by porous, high permeable sediments that are in connection with the underlying aquifers, which effectively extend down into the lower part of the basin.
Therefore, water is able to percolate through these basins into the aquifers and effectively recharge the whole Orange County groundwater basin.
