I have a cement cistern I am using for a storage tank 9' by 9' by 9'. The tank is 10" concrete wall. I am planning on laying down 3 inches of sytrofoam insulation (total R15) on the inside of the tank, then lining the tank with a plastic liner to hold 3500 gallons of water. Two questions:
1. Is this enough insulation?
2. Do I need to use a liner? The cement tank will hold water- Can I just seal the foam insulation well and pour in water?
Tanks! I mean Thanks!
