The water and energy usage and savings figures shown on the aqKWA Savings Engine™ website are estimates only and will vary by household, customer water usage and water-saving behaviour. These savings and usage figures are not guaranteed by either Save Water Save Money or Unitywater, and may not be reflected or be the same as those shown on your quarterly Unitywater water and sewerage bill. The water-saving dollar amounts are based on the usage information you submit via the Savings Engine™, and on Unitywater’s current 2018-19 water usage and sewerage usage charges (excluding fixed access charges) for the region you have selected (either Moreton Bay, Sunshine Coast or Noosa), as published on the Unitywater website at The energy-saving dollar amounts are based on $0.25 per kWh, which is the average of the 2018-19 non-discounted rates from the main electricity providers in South East Queensland, sourced from Energy Made Easy is an Australian Government website for comparing energy prices, maintained by the Australian Energy Regulator (AER).
