If your business uses more than 20,000kL of scheme water a year, you are required to complete a Water Efficiency Management Plan (WEMP) to help you save water. Our business program aims to improve water management for major commercial and industrial businesses.

It involves developing a plan (WEMP) detailing your water saving actions and initiatives and providing annual progress reports about your efforts.

Since its inception our Waterwise Business Program has helped customers save over 111 billion litres of water. We are currently working with 248 customers to help them reduce water use through water recycling, better water management and use of technology.

Program benefits 

  • Gain a better understanding of how water is used in your business
  • Learn new ways to save water in your industry
  • Financial savings through improved efficiency, by avoiding unnecessary water and sewerage charges
  • Access to free training sessions and events to learn fresh ways to save water
  • Access to a free data logger for leak detection

You will also receive exclusive invitations to attend training sessions and a waterwise business forum annually.

At these sessions industry specialists and other WEMP customers will share information on water saving tools, tips and technologies available.

Program tasks

As part of the program you're required to:

  • Develop a Water Efficiency Management Plan (WEMP) detailing water saving targets, actions and initiatives
  • Provide annual progress reports on water saving targets, actions and initiatives.

These reports have been migrated to an online form to streamline the process and provide a better customer experience. Each year we will contact you with a link to a personalised online form to submit your WEMP.

What to include in your WEMP

  • A profile and description of your business and the current site operations
  • Site water use table
  • Water saving opportunities (including benchmark indicators and targets)
  • Water saving action plan (including time frames)

Once your WEMP is submitted and accepted it will be valid for 5 years.

If your business changes ownership or the water use increases significantly a revised WEMP may need to be submitted. We will let you know if this is required.

The information you provide to us will remain confidential.

Why do I have to complete a WEMP?

The State Government introduced this program back in 2007 as part of a range of mandatory water efficiency measures that apply to all sectors of the community.

Under the Water Services Regulations 2013 all large WA business customers using more than 20,000kL of scheme water per year participate in the program.
