Efficient appliances case study
The hotel reduced water use by 25% since 2006, by installing efficient appliances like dual flush toilets, WELS rated showerheads and tap aerators, as well as fostering a water saving philosophy among staff.
How can you do this?
Why we acted
By taking a proactive approach we are staying 1 step ahead of what our customers expect, as well as enjoying the financial savings associated with reducing our use.
Tony Fioraso, General Manager Property Services
Wok stove burners generate high levels of heat for rapid cooking so a continuous flow of water is required to absorb this heat and stop the surface of the stove from overheating. Water is also used to clean the woks in between meals.
Chatters had 8 water cooled woks and were keen to find out how they could reduce water use. They volunteered to participate in a Water Corporation trial of waterless wok technology.
Assess your use
How we did it
Guest rooms at Crown Promenade Perth can consume around 82% of the hotel’s total water use and 70% of each guest’s water use is used in the shower.
Since 2010 we have:
- Retrofitted all rooms with WELS rated water efficient showerheads, which reduced the flow rate from 12 to 9 litres per minute.
- Replaced tap aerators in room basins, reducing the flow rate from 9 to 3.5 litres per minute.
- These initiatives provide added cost savings through reduced energy use from water heating.
- Installed sani sleeves, urinal timers and a bore for garden irrigation.
Our managers attribute water savings to ongoing monitoring and a well-established water saving philosophy across the business involving all staff, as well as our maintenance team.
What we are doing now
We've installed sub-meters at key points on the grounds to better monitor water use, identify and set priorities for water efficiency actions.
Plans are in place to install more sub-meters, along with telemetric metering where meters are hardwired back to a Building Management System. This will enable staff to download reports to monitor consumption, target water savings in particular areas and detect leaks.
Water conservation continues to be a core responsibility for all our staff, forming part of the induction processes. Our maintenance staff are also trained to report any leaks or faults immediately.
What you can do now
- Develop a water saving plan
- Conduct a water audit
- Retrofit shower facilities
