A REDA ESP system was installed in a water well in 1965 to provide a domestic water supply to a farm used for recreational purposes. It worked reliably without any stoppages for servicing until it was finally replaced in 2019.

The pump itself was still operational when it was removed from the ground. However, while replacing a leaking check valve, the owners took the opportunity to switch out the pump—hoping that the new one will now last until 2073!
