Today we received a call from a happy customer. After installing a 8000 litre tank her water bill for the last quarter was just $12. This tank only catches half of the roof water. There is a connection to town water that kicks in when the tank gets low. We also installed a device that allows the first part of the rain caught to run off so that only clean water is stored in the tank. Inside we installed a filter so the water is good for drinking, washing clothes, showering and everything else.
