At this rock formation on the side of a hill on our property in an undisclosed location, there is water that “constantly” runs 24/7 from a small trickle to a large flow. The trickle if 100% of the runoff was collected would amount around 2-3 gallons of flow per minute! This is over 4,320 gallons of fresh naturally filtered water daily. Even at 1 gallon it made our 500 gallon gravity feed water cistern overflow in less than 24 hours.
