In our first installment we noted that while sustainability may have fallen out of favour in the current American political and regulatory environment to the point that we had to counter the Chief Sustainability Officer graphics going around earlier this year with a Chief Sustainability Officer: USA Edition, sustainability, at its core is becoming more and more important to corporate survival. In our second installment, we described how sustainability concerns permeate every department of the organization, and failing to adhere to them is not only unsustainable in the environmental sense, but also in the business sense. In our third instalment we dove into the stakeholder engagement that is required for true sustainability success.

Then, in our last (forth) installment, we started outlining the key areas of focus to identify the key projects that will increase both environmental AND business sustainability, starting with energy. In today’s, fifth, post we continue with key project identification in the areas of (fresh)water and resources.

(Fresh)Water Reduction

Water shortages and scarcity is becoming all too common. More than 50% of the USA — the richest country in the world which, theoretically, could have the best infrastructure — has suffered droughts and water scarcity issues, with scarcity often getting so bad in parts of California that even the US President says they need to open a very large faucet (which doesn’t exist, but it is needed).

It’s so bad in California that they had to serve Nestlé a cease-and-desist order to stop it from taking millions of gallons of water it wasn’t entitled to. (Source: The Guardian). Thus, unless you want your taps to run dry (either due to lack of water availability or the local government agency literally turning your taps off), you need to minimize your water usage.

The major uses of water in most businesses, depending on the business type, are:

• Restrooms/Showers Old fashioned, high water usage toilets and urinals, and high-flow shower heads (instead of low-flow, high pressure) combined with poor maintenance with constant, unaddressed, slow leaks waste a considerable amount of water. Reductions of up to 50% water usage with proper equipment selection and installation are possible. (Proper selection is key, not all low-flow models actually meet the MaP test measure they advertise, and a high scoring model is key, because you don’t save water if you have to flush two or three times.)
• Water Cooling This is especially critical in power plants (which can consume millions of gallons of water daily) and IT data centers (which can also consume hundreds of thousands of gallons of water daily). Because contaminates like minerals, scale, and bacteria build up over time and evaporation occurs, water cannot be reused indefinitely, but with proper treatment and filtering and cooling systems (passing through high efficiency refrigerated zones), the amount of freshwater required can be greatly reduced, especially if there is a renewable energy source to power the refrigerant based cooling in the closed-loop system (and extremely good high-efficiency reverse osmosis systems). With today’s technology, except for regular top-up to deal with evaporation, it is possible to recycle water for years, whereas a decade or two ago the systems might have needed to be flushed every few months.
• Irrigation Many office buildings or facilities also include land with greenery that needs to be maintained, usually with fresh water, which, in peak heat periods, can consume thousands of gallons of water a day — if the facility installs a small wastewater filtration and management system, as well as an underground irrigation system, a lot of the wastewater that goes through its building sinks and showers can be automatically pumped through the irrigation system, minimizing the need for freshwater for irrigation

We’ll continue with the other areas in our next installment.
