How the hot springs form at Bath•The water fells as rain on thenearby Mendip Hills.• It percolates down throughlimestone aquifers to a depth ofbetween 2-4 km where geothermalenergy raises the watertemperature.• Under pressure, the heated waterrises to the surface along fissuresand faults• Hot water at a temperature of 46°C rises here at the rate of 1 millionlitres every day.
