How long will the groundwater supply last?

High rate pump testing conducted during pre-design indicated there was an abundant supply of water available from the aquifer. Little draw down has been observed in the deep aquifer since the Mint Farm Regional Water Treatment Plant started producing water, further confirmation the aquifer is a sustainable supply. Static water level is continuously recorded in the deep monitoring wells which surround the Mint Farm wellfield and the data confirms the aquifer is continuously recharged during pumping.

To meet current demand, approximately 5 million gallons per day are pumped from the aquifer and we are confident the aquifer will easily continue to meet our needs as demand grows to 20 million gallons per day, in the future.
