An effective water stewardship strategy must be business-specific
Strategy depends on- How and where a business faces water risk
• Physical, economic, reputational
- How and where the business impacts water
Risk:QuantityQuality
CostLicense to operate
Impact: Source depletion

Location, location, location
Different concerns in different places
![Page 5: Water Stewardship: Looking In, Out, and Beyond · 2015-10-22 · Water Stewardship: Looking In, Out, and Beyond. In one way or another, every business relies on water Operations](https://reader035.vdocument.in/reader035/viewer/2022062919/5f01badb7e708231d400c242/html5/thumbnails/5.jpg)
Can locations with plenty of water face water stress?
Water stress: the ability (or lack thereof) to meet human and ecological demand for freshwaterComponents: availability, quality, accessibility
![Page 6: Water Stewardship: Looking In, Out, and Beyond · 2015-10-22 · Water Stewardship: Looking In, Out, and Beyond. In one way or another, every business relies on water Operations](https://reader035.vdocument.in/reader035/viewer/2022062919/5f01badb7e708231d400c242/html5/thumbnails/6.jpg)
First step: identify and prioritize locations facing water stress
You have to understand the problem before you can solve it!
![Page 7: Water Stewardship: Looking In, Out, and Beyond · 2015-10-22 · Water Stewardship: Looking In, Out, and Beyond. In one way or another, every business relies on water Operations](https://reader035.vdocument.in/reader035/viewer/2022062919/5f01badb7e708231d400c242/html5/thumbnails/7.jpg)
Publicly available mapping tools provide a ‘first look’
But does this agree with experience??Global maps = pretty good in most places, perfect in very few
![Page 8: Water Stewardship: Looking In, Out, and Beyond · 2015-10-22 · Water Stewardship: Looking In, Out, and Beyond. In one way or another, every business relies on water Operations](https://reader035.vdocument.in/reader035/viewer/2022062919/5f01badb7e708231d400c242/html5/thumbnails/8.jpg)
Mapping information should be validated – or contradicted – through on-the-ground surveys
![Page 9: Water Stewardship: Looking In, Out, and Beyond · 2015-10-22 · Water Stewardship: Looking In, Out, and Beyond. In one way or another, every business relies on water Operations](https://reader035.vdocument.in/reader035/viewer/2022062919/5f01badb7e708231d400c242/html5/thumbnails/9.jpg)
Some industries are clearly water-intensive
Others may be a little less obvious
Water in operations
![Page 10: Water Stewardship: Looking In, Out, and Beyond · 2015-10-22 · Water Stewardship: Looking In, Out, and Beyond. In one way or another, every business relies on water Operations](https://reader035.vdocument.in/reader035/viewer/2022062919/5f01badb7e708231d400c242/html5/thumbnails/10.jpg)
Awareness
Associates can see that water’s important in plant operations – but do they know howimportant?
Important first steps:- Get people to see the water that’s all around
them- Connect gallons to dollars
![Page 11: Water Stewardship: Looking In, Out, and Beyond · 2015-10-22 · Water Stewardship: Looking In, Out, and Beyond. In one way or another, every business relies on water Operations](https://reader035.vdocument.in/reader035/viewer/2022062919/5f01badb7e708231d400c242/html5/thumbnails/11.jpg)
170 gallons per day62,000 gallons per year
3,600 gallons per day1.3 million gallons per year
970 gallons per day355,000 gallons per year
Each 1/8" leak:
Each 1/16" leak:
Each pinhole leak:
$ per year - water$ per year - sewer
$ per year - water$ per year - sewer
$ per year - water$ per year - sewer
One little leak can cost a lot!

Identifying and prioritizing actions requires some basic information
How much water is being used?
How much does that use cost?
![Page 13: Water Stewardship: Looking In, Out, and Beyond · 2015-10-22 · Water Stewardship: Looking In, Out, and Beyond. In one way or another, every business relies on water Operations](https://reader035.vdocument.in/reader035/viewer/2022062919/5f01badb7e708231d400c242/html5/thumbnails/13.jpg)
Really – how much does water cost?
Treating it Heating it
Getting rid of it
Getting it
Moving it
![Page 14: Water Stewardship: Looking In, Out, and Beyond · 2015-10-22 · Water Stewardship: Looking In, Out, and Beyond. In one way or another, every business relies on water Operations](https://reader035.vdocument.in/reader035/viewer/2022062919/5f01badb7e708231d400c242/html5/thumbnails/14.jpg)
Initiatives can be prioritized based on potential water – and money – savings
Water use breakdown, % volume
Water use breakdown, % cost

Water management hierarchy
Avoid Discontinue water usage where possible
Improve water efficiency by using less water to perform the same function
Capture waste stream from one process and use it in another process
Capture waste stream, treat, and return to start of system
Reduce
Reuse
Recycle

Hardware’s important –team engagement is a necessity
- A little friendly competition never hurts!- Example: Water Loss Lottery
• Held over a single 24-hour period• Small prizes• Management support and followthrough is critical
WATER LOSS LOTTERY
How many leaks, drips, and other water wastes (big or little) can you find?
Name Shift
Leak/drip/waste description (be sure to give details so we can find it and fix it):
Every find = 1 entry!

Start with awareness - Is water important in your supply chain?- Where?
Water in the supply chain
![Page 18: Water Stewardship: Looking In, Out, and Beyond · 2015-10-22 · Water Stewardship: Looking In, Out, and Beyond. In one way or another, every business relies on water Operations](https://reader035.vdocument.in/reader035/viewer/2022062919/5f01badb7e708231d400c242/html5/thumbnails/18.jpg)
Once you understand where water-intensive items are sourced, use mapping tools and other resources to prioritize
Key questions- Which supply chain elements have significant
water risk associated with them?- Are there alternative sources?- Can ingredients/components be replaced with
other materials?
Water in the supply chain
![Page 19: Water Stewardship: Looking In, Out, and Beyond · 2015-10-22 · Water Stewardship: Looking In, Out, and Beyond. In one way or another, every business relies on water Operations](https://reader035.vdocument.in/reader035/viewer/2022062919/5f01badb7e708231d400c242/html5/thumbnails/19.jpg)
Water in the community…or communities
Which community?- Plant location- Supplier location- For publicly-facing companies, consumer
location
If a community is – or could become –concerned about the impact business is having on its water resources, community engagement is an integral component of water stewardship strategy.

It’s all local
All watersheds are not created equal– There’s no one-size-fits-all
solution
Different situations call for different solutions
– Business platform– Climate– Local economy– Degree of immediate and long-
term water stress

Key questions
What makes sense in this place, at this time?
What’s the best process for selecting the path forward?
Who are the interested parties?

Summary
An effective water stewardship strategy is business-specific
- Challenges need to be faced where they occur • Operations and/or supply chain and/or community• Geographic location
- Solutions need to be locally relevant
Corporate solutions can provide a framework but need to be flexible enough to be effective locally
Transparency and engagement should be no-debates
