Things to consider:
- Location – once the tank is full it is going to very heavy, can the location take the weight?
- Maintenance required
- Will a pump be required or will it rely on gravity?
- Size (A simply DIY tank that connects to down spout (200 litres) or something larger? (Self sufficiency you would need 20,000 to 25,000 litres) A larger tank may require consent?
