Western Australia’s Water Corporation has developed a [clickandtweet handle=”” hashtag=”” related=”” layout=”” position=””]drought-proof plan for Perth to ensure there is enough water for all[/clickandtweet], even in the face of climate change and an increasing population. The plan aims to achieve the city’s goal of reducing water consumption by 25% by 2060. To help business and industrial customers reduce their water consumption and become drought-proof the Water Corporation has initiated its Water Efficiency Management Plan Program.
Water Efficiency Management Plan Program
The Water Efficiency Management Plan Program requires all businesses using more than 20,000kL of water a year to complete a Water Efficiency Management Plan (WEMP) to help save water. The program involves businesses detailing water saving actions and initiatives and providing annual progress reports about their efforts. As part of the program a WEMP includes:
- Site water use history
- Water saving opportunities (including benchmark indicators and targets)
- Water saving action plan (including time-frames)
- Management and Water Corporation commitment
Water Efficiency Management Plan Program benefits
Once the WEMP is submitted and accepted the plan is valid for 5 years. However, if the business changes ownership or water use increases significantly a revised WEMP may need to be submitted. To date 379 business are participating resulting in water savings of 45.6 billion liters over 7 years. In 2013-2014 alone 13 billion liters of water was saved. In addition to saving water businesses benefit from the program by:
- Making financial savings through improved operational efficiency
- Receiving recognition as a leader in water use efficiency and conservation
- Improving public perception of the business

WEMP Recognition Scheme
To encourage businesses to go the extra mile in saving water the WEMP Recognition Scheme was established in 2012. Based on their water savings businesses could receive one of the following awards:
- Champion: Achieved gold recognition or better for 2 consecutive years
- Platinum: More than 50% improvement in water efficiency
- Gold: 35-50% improvement in water efficiency
- Silver: 25-35% improvement in water efficiency
- Bronze: 10-25% improvement in water efficiency
There are multiple benefits from being recognized as a water-efficient business including:
- Receiving a certificate profiling the category of award received
- Free publicity on Water Corporation’s website and forums
- The potential for a case study on the business’ water-saving achievements that will be posted on Water Corporation’s website
- Promoting the award received on the company website and communications
- The potential of becoming a water Champion
The take-out
Voluntary measures can be added to mandatory water conservation measures to encourage commercial customers to go the extra mile in saving water, which in turn provides businesses with numerous intangible benefits.
