Non-residential customers account for about 25 per cent of total demand for water in Melbourne. Victoria's non-residential sector – this includes industrial, commercial and institutional customers – is becoming increasingly water efficient.

Melbourne's non-residential customers have made significant water savings, reducing their per capita daily water consumption by about 49 per cent in 2011-12 compared to 1999-2000. This is in line with Melbourne's overall reduction of around 43 per cent over the same period.

The Schools Water Efficiency Program (SWEP) assists Victorian schools to monitor water usage to help identify leaks, and educates students on water consumption. SWEP provides schools with data loggers to continuously record water use, and access to an interactive web portal so the information can be used as part of the school curriculum, and to help manage water use.

The Smart Water Advice website provides water utilities, customers and councils with a range of educational, interactive water saving resources. It was created after a successful industry collaboration and negotiation between Victorian water corporations, DELWP and Smart-Approved Watermark.
