The Water System Improvement Calculator is a practical tool designed for water utilities, councils, and asset managers to estimate the potential impact of water loss reduction and network upgrades. By inputting key parameters, users can quantify benefits such as reduced non-revenue water (NRW), lower leakage volumes, and improved system efficiency. This calculator supports data-driven planning and investment in smarter water networks, helping prioritise initiatives that enhance drinking water system performance. Aqua Analytics, a leader in water network management across Australia and New Zealand, has customised this tool to empower users to make informed decisions that support long-term sustainability and asset optimisation.
