1. Introduction 

As the main provider of water and wastewater services across the State, the Corporation is 

committed to providing a sustainable water service for current and future generations. 

In October 2009, the Corporation released its 50 year plan, Water Forever, Towards Climate 

Resilience to provide a sustainable water service for future generations living in Perth and 

Mandurah. 

The plan addresses the challenge of providing water for all: 

• In an even drier climate 

• With twice as many people 

• With less environmental impact 

Adopting a portfolio approach, the plan identifies over 800 

gigalitres of water supply and demand options (Figure 1). 

By 2060 working in partnership with the community, the 

Corporation will: 

• Reduce water usage by 25% 

• Recycle up to 60% of wastewater in Perth-Mandurah 

• Prepare a diverse range of water source options for future 

development 

Figure 1: Portfolio of water options 

As part of its community focus on water conservation, the Government requires all WA business 

customers using more than 20,000kL of scheme water per year, to participate in the Water 

Efficiency Management Plan (WEMP) program. This involves: 

• Developing a Water Efficiency Management Plan (WEMP) detailing water saving targets, 

actions/initiatives and 

• Providing annual progress reports on water saving targets, actions/initiatives 

These are requirements under the Water Agencies (Water Use) By-laws 2010 and are 

mandatory. 

1.1 Objectives 

The objectives of the WEMP are to: 

• Assess current water use on site 

• Identify inefficiencies and potential water savings 

• Set a target for improving water use 

• Prepare an action plan and implement water conservation actions to progress towards your 

target 

• Provide a process for annual reporting on implementation of water conservation actions 

1.2 Methodology 

The major steps involved in developing a WEMP are: 

• Collection of information and water use data particularly in high use areas 

• Development of a water balance table (section 3.2) 


3

• Development of water use benchmarks and targets 

• Identification of opportunities for improvement 

• Completion of a water management action plan 

1.3 Benefits in participating in the program 

• Lower your operating costs 

• Reduce your carbon footprint 

• Help save the environment 

• Improve your public perception 

Executive summary 

This Water Efficiency Management Plan (WEMP) has been prepared for CosyComfort Hotel Pty 

Ltd. 

The objectives of this WEMP are to: 

• Assess current water used on site from all sources (e.g. scheme, self-supplied groundwater, 

recycled, reclaimed etc) 

• Identify inefficiencies and potential water conservation measures (including savings) 

• Prepare an action plan to implement water conservation actions 

• Provide a platform for annual reporting on implementation of water conservation actions 

An assessment of CosyComfort Hotel Pty Ltd at 821 Line Terrace Perth WA 6000 showed that 

scheme water use at the site had increased annually since 2008. In 2010/2011, CosyComfort 

Hotel Pty Ltd at 821 Line Terrace Perth WA 6000 used a total of 34,006 kL of water, which could 

be equated to 0.95kL/occupied room. 

An assessment of current practices on site revealed that a 3% reduction in Benchmark could be 

achieved through the implementation of various water saving measures as outlined in Section 5 

– Opportunities to save water. 

What does your business do Describe your business and site activity. 

e.g. Hotel – number of rooms, rooms sold on average, number of staff, gym/ spa/ pool 

CosyComfort Hotel is a four year old 3.5 star hotel located in East Perth Western Australia with 

100 rooms including luxury Spa Suites with views of the city skyline, a function room, a board 

room, a gymnasium and a café which combines the best of modern city dining and relaxing café 

culture. 

The CosyComfort Hotel is aware that there is scope to improve the water management practices 

and reduce water consumption at the complex. We have made a formal commitment to improve 

the environmental water management at the premises. There has been no formal monitoring 

and measurement programme at the complex however over the life of the Water Efficiency 

Management Plan Program this will alter.

3. Water Use 

3.1 Baseline Water Use – Scheme Water 

Total water and average daily usage tables have been provided for you to compare years and 

make assessments for setting your water saving targets. 

Please let us know if you have had any unexplained/ high water use in the past year that may 

affect your regular water use for this site. 

E.g. days of operation, production rate, plant shutdown, site construction etc 

• Construction ceased in June 2009 and the hotel became operational July 2009. During 

our first year of operation we maintained a 75% capacity rate. In 2010/2011 our room 

occupied rate increased from 75% to 78% which increased our water usage. If we 

continue to surpass our previous years occupied room rate we expect our water use to 

increase. Investigation into water efficient solutions to reduce our water use whilst 

increasing occupied rooms has commenced. 

3.2 Water Balance 

A water balance is a measure of how much water is entering and leaving your site. Working out a 

water balance for your site will help you understand where water is being used. This makes it easier 

to identify and prioritise your water saving opportunities. 

By entering the relevant data in table 3 you will be able to determine the percentage of water used 

in each major area.

A Waterwise Water Auditor can help you investigate where your water is going, and give you advice 

on making your water use more efficient.

4. Indicators and Targets 

4.1 Benchmarking 

Benchmarking determines how much water is consumed on site relevant to your industry, and allows 

realistic and measurable targets to be set. Determining an appropriate benchmark will allow water 

use comparisons to be made each year. 

To be eligible for the WEMP recognition program you must use the relevant industry specific 

benchmark indicators approved by the Water Corporation as shown in the table below: 

Table 4a Benchmark Indicators 

Industry Type 

Shopping Centre 

Hotel / Motel 

Caravan Park 

Wharf / Port 

Hospital 

Mining

4.2 Water Efficiency Target 

Setting water reduction targets will help drive the implementation of water conservation actions 

in your business. Targets need to include a realistic timeframe and the base year from which 

improvements will be measured. 

Based on results observed to date, we recommend that your short-term water efficiency targets 

should be at least a 3 - 5% reduction from your baseline. 

4.2.1 First Year Water Efficiency Target(s) – Short Term 

The short-term water efficiency target(s) is/are a percentage reduction or your benchmark 

target for the coming year. 

What is your reduction % target 

3% reduction in water use and benchmark to reduce water use to 32,985kL and benchmark to 

0.92kL 

How are you going to achieve this target 

Education of staff and visitors 

Installation of waterless urinals 

5. Water Saving 

Here are some examples that could help form the basis of your action plan in table 6. 

5.1 Operational Efficiency and Conservation 

Increasing the operational efficiency of plant and equipment on site is one of the easiest ways to 

ensure water is used as efficiently as possible, have you thought about: 

• Regular water meter readings in an effort to create consumption trends and analysis of data 

that may lead to the identification of any leaks. 

• Installing sub-metering on key plant and major water using areas 

• Installation of water efficient appliances (taps, toilets, showerheads) 

5.2 Education and Awareness 

Staff, tenant and community education and awareness can lead to improved water use. Consider 

actions including: 

• Addressing water efficiency at staff meetings and actively engage staff in water saving ideas 

and opportunities 


8

• Incorporating water efficiency in new staff inductions and training. 

• Place stickers and/or posters in common areas such as kitchens and amenities promoting 

water efficiency 

5.3 Water Re-use and Wastewater Management 

Water re-use and improved wastewater management will enable the targets set in Section 4 to 

be achieved, you could consider: 

• Review rain water harvesting opportunities and potential use in cooling towers, toilets, 

irrigation and on site water treatment 

• Investigate opportunities to reuse grey water 

You can find more information and resources on our website, including information sheets, 

checklists, resource tools and case studies.
