Waterwise Office Program

Give your business a leading edge by signing up to be Waterwise - it’s free and easy to join!

We've partnered with the Property Council of Australia and City of Perth to develop the Waterwise Office Program to support Perth's commercial office sector reduce their water use. The program provides water use performance indicators so that you can assess whether your building is water efficient and identify opportunities for improvement. Since the introduction of this program in 2013, Perth offices larger than 5000mhave saved more than 254 billion litres of water!

We have a long term plan in place to secure water for future generations to come supporting our goal to transition Perth to a water sensitive city by 2022. The commercial office sector presents opportunities to be innovative and efficient with water management to deliver liveable, resilient, sustainable and productive communities.

Invest in a NABERS water rating today

Our very own John Tonkin Water Centre was recently accredited with a 4-star water rating through the National Australian Built Rating System (NABERS) helping us better understand the environmental performance of our office.

To encourage the environmental performance of the commercial building sector the City of Perth is offering sustainability grants to Perths' businesses and building owners. Find out if your building is eligible for a sustainability grant here.

 

The industry baseline was determined through a review completed by HFM Asset Management, on behalf of the Water Corporation and Property Council of Australia, of water use and net lettable area (NLA) data for office buildings with a NLA greater than 5000m2 within the Perth, East Perth and West Perth CBD.

 

The results of this review are used to determine the waterwise recognition categories for water-cooled and air-cooled buildings. The industry baseline is reviewed every 2 years to ensure best practice water use within waterwise offices. Read the full report here..

This program provides a benchmark for water efficiency in businesses that haven’t already invested in a water rating through the National Australian Built Environment Rating System (NABERS). Case studies show that bench-marking water usage and planning for improvement can reduce operating costs including sewer volume charges and the costs associated with heating, pumping and treating water.

 

Other key benefits are:

 

  • Recognition as a leader in water efficiency by Water Corporation, Property Council of Australia and City of Perth.
  • Exclusive access to the waterwise logo to promote your office as waterwise endorsed.

  • Access to tools such as data loggers and resources (stickers and posters) to encourage waterwise behaviours.

  • Potential for improved sustainability ratings and reduced operational costs and water use achieved by improved water efficiency.

  • A competitive edge when promoting your business as a sustainable place to work.

  • Opportunities to show case your water saving initiatives through case studies on our website.

  • Invitations to workshops, offers, networking and industry events.

  • Free online Waterwise Training for the team at your office.

Eligibility

To be eligible to join the program your office must have a net lettable area (NLA) larger than 5000m2 and commit to the following:

 

  • Building owner or appointed representative must accept and submit the program commitment letter.
  • Complete a water management plan in the first 3 months following the commitment letter where you will set targets to improve water use.

Endorsement

To be endorsed as a Waterwise Office, the building must demonstrate water use performance in the water management plan that is equal to or above the industry baseline and submit an annual report to provide feedback on your water efficiency progress.

 

  • 0.86kL/m2NLA/year for a water-cooled building
  • 0.75kL/m2NLA/year for an air-cooled building

 

Recognition

Recognition occurs annually and eligible participants will receive exclusive access to the waterwise logo and a certificate to acknowledge your water use performance and recognition category (silver, gold, platinum).

This information is provided as a guide only.

** To be eligible to receive Gold or Platinum levels of recognition a current NABERS Water Rating is required. This allows us to independently validate the results of high performing buildings before they are recognised as such.

Water use performance

To calculate your water use performance, divide your annual water use (based on reading year – contact us if you need the data) by your NLA. This gives your water use performance in kilolitres per square meter per year.

 

Tip! Use your submeter data to subtract water use from other facilities, such as food or retail outlets, in your calculations.
