Water has always been a major problem for the Cornish miner as mining progressed deeper underground.
From the start of the 20th Century electric pumps began to be introduced, and these were in use at Geevor until the mine’s closure.
Geevor pumped approximately a million and a half gallons of fresh water a day from underground. The mill used all of this water to process and clean the ore at a rate of 2000 gallons per minute.
Geevor was a relatively dry mine compared to other Cornish mines such as Wheal Jane near Chacewater which pumped approx 14 million gallons of water per day.
