What you have is called an artesian well, the geologic pressure is causing the water flow. The well could produce this way for decades (or a short time). I know of these types of springs here in the US. that produce for generations. Do not be concerned unless you note the flow decreasing. I agree with Larry Duty, the water is not wasted, it replenish the spring. KEEP IT CLEAN!!!!
