Questions about the NRWA Savings Engine


What is the NRWA Savings Engine?

The NRWA Savings Engine is owned by Save Water Save Money, and is an interactive, personalised online tool to help you save water, energy and money. It asks you a set of simple questions about your water and energy usage — and then gives you your very own tailored results, plus active, ongoing help with saving.

How accurate are the results of the NRWA Savings Engine?

The accuracy of your results is based on how precisely you answer the questions. We know from more than 8,100 customer reviews that the usage and savings calculations made by the NRWA Savings Engine are good estimates, and as close as possible to actual usage.

Save Water Save Money has been promoting water-saving for more than ten years. Based on our experience, the water, energy and money savings identified in the NRWA Savings Engine are good estimates of what your household could save if it carried out the personalised water-saving actions suggested.

Of course, as the calculations provided are estimates based on the information you provide, they can't be exact, and are intended as a guide only.

How is the NRWA Savings Engine relevant to me?

What's unique about the NRWA Savings Engine is that it lets you tailor your questions to those that are relevant to your home — saving you time, as well as water and money. So for example, if you don't have a garden, then it won't ask you how long you take to water your plants. It really is all about you.
