Water Energy Calculator (WEC)

Water efficient businessSteps to Sustainable Water Use

Most businesses can reduce their water use with a few simple steps.

Our 5 Step Plan

1. Measuring how much you use

2. Tackling leaks and excess water pressure

3. Reducing how much water you use

4. Changing water use behaviours

5. Monitoring savings and celebrating success

All of our business customers have a measured supply. This helps to calculate consumption and benchmark you site’s water use.

New Smart Metering

• Use of AMR to get real time data & management

Leaky pipes on a customer’s property are their responsibility. We help you to find them and fix them.

Water Audits

• Identify points of water use

• Carry out a Water Mass Balance

• Use to identify leakage and wastage

• Facilitate appropriate remedies and fixes

Examples:

Reducing water use for business is a combination of installing free devices and taking a holistic look at your water use and behaviours

Each year we visit business customers to share the water efficiency message and we support employee engagement.

Water in our homes: raising the profile

EU Life+

Combining water and energy efficiency

EU Life+ Project: Main Findings

• ‘top tips’ style advice through light touch methods (phone and mail) resulted in little increase in water saving awareness or behaviour change

• The tailored in-home approaches, provided a better quality of advice, and resulted in increases in water – energy awareness and actual behavioural change

• Greater benefit for householders when advice is combined with device installation (aerated taps, water efficient shower heads, etc)

• Greater benefit for customer when combining water and energy efficiency advice and retrofit - integrated customer engagement approach

• More cost effective delivery method
