If you’re one of those folks out there who is suffering from a bit of carbon fatigue, then a post in the NY Times’ Green Inc. blog this week could either provide additional motivation for green projects or increased fear of another jargon-laden debate. Green Inc highlighted the growing trend of striving for “water neutrality”, as highlighted at the Fifth World Water Forum in Istanbul last week.
The idea is gaining ground within a group of companies looking to understand and reduce their consumption of water, including Coca Cola, whose chairman has pledged to eventually balance out all of the water used in its products and manufacturing processes through conservation elsewhere (over 80 billion gallons worth!).
This got me to thinking: what would it take to be water-neutral in our own homes, meaning that we don’t import any net water? If we include all of the water that goes into our food and the products we consume, then it gets ugly real fast (see this post on the water content of food, for example). But what about our direct water use - showers, irrigation, toilets, etc?
Now, this would require some significant changes to a home and to local building/health/safety codes, since the only way to go water-neutral is to reuse graywater and harvest/store rainwater. Both of these options now face numerous permitting and legal obstacles around the country (including some pretty counterintuitive ones, like Utah and Colorado bans on capturing ANY rainwater at your home). Assuming we could, though, how much rain would it take to provide a family’s annual water needs?

SAB Ltd, is funding water saving projects to compensate for its potential water consumption of 14 billion litres a year in South Africa. WWF (World Wildlife Fund) is facilitating the “water neutrality” process with a South African Government Project to ensure that this is not just a multinational greenwashing.
SAB Ltd is the South African subsidiary of SABMiller which is the second largest brewery in the world .
Water Neutrality
In October 2008, Dr Deon Nel, Head of the WWF Sanlam Living Waters Partnership explained
“The concept of water neutrality, based on its carbon equivalent, has been used loosely over the past years; however, until now no-one has been able to quantitatively justify these claims. We believe that our scheme is the first in the world that allows participants to truly claim to be water neutral.”
Participants will replenish water supplies, by investing in projects that quantitatively supplement water supplies equal to their water usage.
Note: Water neutrality has taken on a form in certain areas that is significantly different to the process introduced here by WWF.

The business case for reducing corporations’ water footprints was explored at last week’s Corporate Water Footprinting conference held in San Francisco.
“Water is the new carbon,” said Gil Friend, President and CEO of Natural Logic, during his moderation of a session on “The Outlook for Water Supply Shortages.”
The conference, held December 2 and 3 and organized by Green Power Conferences, engaged corporations to discuss how to become more proactively involved in the water management of their facilities. Companies such as The Coca-Cola Company, PepsiCo International, Nestle Waters, MillerCoors, and Cadbury were represented. Professors, water experts and consultants from a variety of firms, including Business for Social Responsibility and Natural Logic, also participated in panels.
