I'm the happy new owner of a 60 feet by 7.5 feet swimming pool (depth 3.6 feet). But I'm getting worried about the water consumption. I have no hard data yet but it seems like it consumes over 2500 gallons of water per month. I live in Belgium, that's not the hottest country in the world. I keep my water at >= 25 degrees with a heat pump and a solar lamellae cover. My provider claims this is normal, I really doubt so. Do you have an idea of what a normal water consumption would be? Or how to calculate?
