Calculate costs & savings for rain tanks, sewage
Cost benefit analysis for water and sewage
Use this calculator to provide a straightforward comparison between a business as usual, conventional domestic energy, water and sewerage system, and what can be achieved today with systems to save energy and water.
Download the calculator; it’s an Excel spreadsheet so you will need to have that program or one which can ‘read’ it on your computer.
Just insert your best-guess figures for your own home into the cost calculator.
