Overview
  • Introduction to Envirowise
  • Water saving - a quick overview
  • Support available from Envirowise

3
Envirowise
  • Funded by Government
  • Re-launched on 1 November 2000

Aim To reduce environmental impact whilst
helping companies to become more competitive
4
Envirowise
  • Reduced raw material use by over 240,000
    tonnes/year
  • Reduced solid waste disposal to landfill by over
    1 million tonnes/year
  • Reduced water and effluent by over 46 million
    m3/year
  • Achieving savings of 125 million/year

5
Envirowise
  • Focuses on best practice in business
  • Waste Minimisation
  • Cleaner Technology
  • Demonstrates the benefits and promotes
    implementation of best practice
  • Minimising waste increased efficiency and
    competitiveness

6
Why Saving Water is Important
7
Why is saving water important?
  • Usual reasons are to
  • Reduce water consumption
  • Reduce costs
  • Reduce environmental impact

8
Water-related waste
  • All companies produce waste
  • Waste can constitute, on average, 4 of business
    turnover
  • Water management can contribute to savings in
    waste

9
4
THE COST OF WASTE...
Easily Identified Costs
Hidden Costs
10
Overuses of water
  • Excessive or unnecessary use
  • Unknown or unauthorised use
  • Unidentified or cross connections
  • Broken valves
  • Incorrectly set valves or control systems
  • Leaks, etc

11
Water losses from a tap
  • 3 mm stream
  • 600 cm3/minute
  • 336 m3/year
  • 193 - 519/year

There are a lot of minutes in a year!!
12
Typical water losses
One drop/minute 79 litres/year 5 - 12
pence/year 0.1 litre/minute 53 m3/year 30 -
82/year 7 - 14 litres/minute 3 680 - 7 360
m3/year 2 112 - 11 376/year
15 mm copper pipe
Valve
1/2 Ballvalve

  • efficient use of water resources
  • waste minimisation
  • effluent treatment
  • disposal)

Saving water - practical tips
22
A simple water balance
  • Based on a very simple concept what goes in must
    come out (somewhere)

23
A simple water balance
  • Water inputs
  • Water distribution
  • Main points-of-use
  • Assembly of existing data
  • Water outputs
  • Drainage system
  • Main points-of-generation
  • Assembly of existing data

24
How do we measure flow?
  • Simple but effective
  • Reading existing meters
  • Bucket and stopwatch
  • More complex, eg flowmeter

25
