4 steps to becoming a better water steward

Earlier this year, the United Nations declared that the world faces “global water bankruptcy.” Not stress. Not a crisis. A state where many water systems can no longer return to their historical baselines, no matter what interventions we make.

This reframing should fundamentally change how organizations think about water and prompt them to support environmental security. Global freshwater withdrawals increased 630% from 1900 to 2010, according to AQUASTAT, while the world’s population grew by a factor of about four over the same period. Industry and agriculture drive that gap. And the costs of inaction are becoming harder to ignore. According to the Alliance for Water Stewardship, one in five companies now reports significant water risks in its supply chains, affecting billions of dollars in assets.

Most companies manage water only at the site level. That’s a start, but it’s not stewardship. True water stewardship requires understanding how the water supply chain works and the effects that organizations have on it.

Here are four steps that any industry can take to move from basic water management to genuine stewardship.

Know your water
Hydrologists classify water by type, and each category tells you something different about your exposure and your impact.

Blue water is the freshwater found in rivers, lakes and aquifers, the sources most companies and municipalities draw from directly. According to the International Water Management Institute (IWMI), roughly 40% of the precipitation that falls on land becomes blue water. Green water, which IWMI says accounts for the remaining 60%, is the moisture held in soil and taken up by plants. Green water rarely appears on a facility’s water balance sheet, yet it sustains the agricultural supply chains many industries depend on. Gray water is wastewater that has been treated so it can be reused for non-potable purposes like cooling, irrigation, process makeup or other applications where drinking-water quality isn’t required.

Most companies only track blue water — how much they pull from the municipal supply or a local well. But mapping all three categories gives you a much clearer picture of your true water footprint and where your vulnerabilities are. A food and beverage manufacturer, for example, may find that 85% or more of the water embedded in its products is green water tied to agricultural raw materials. If drought affects those growing regions, no amount of on-site treatment will solve the supply problem.

A comprehensive water audit maps every water stream across your facility, identifies where water is being lost or used inefficiently and creates a detailed water balance that shows where improvements will have the most impact. Without that baseline, the ensuing steps are guesswork.

Treat what you use and what you return
Once you understand your water consumption, the next step is improving both the quantity and quality of your water management at the site level.

On the quantity side, this means reducing consumption through process optimization, recycling process water where quality standards allow and recovering water from waste streams. On the quality side, it means ensuring that the water you discharge meets or exceeds local standards, because poor-quality discharge degrades the freshwater sources that you and your neighbors depend on downstream. This is where water treatment technology has the most direct impact. 

Aerobic wastewater treatment, ion exchange, reverse osmosis systems and spiral wound membranes can recover water that would otherwise be lost to discharge, while also improving the quality of what goes back into the environment. The financial case often makes itself: Lower intake volumes mean lower costs, and higher cycles of concentration in cooling systems mean less blowdown and less makeup water. There’s also a lower likelihood of downtime due to droughts or a decrease in the quality of water from a local watershed.

Beyond savings, regulatory requirements are tightening worldwide. The EU’s Corporate Sustainability Reporting Directive (CSRD) requires more than 90,000 European companies to disclose water-related risks and dependencies, and similar frameworks are gaining traction in other regions. 

Collaborate across your watershed
If every company drawing from the same watershed optimizes independently without considering cumulative impact, the shared resource still degrades. True water stewardship requires understanding who else is drawing from the same sources, what the collective demand looks like relative to supply and where shared investments could yield better outcomes than individual ones.

The Alliance for Water Stewardship (AWS) provides a structured framework for exactly this kind of engagement. Its international standard guides sites through understanding their water context, taking meaningful action and engaging with local stakeholders. More than 400 sites worldwide now hold AWS certification, and the standard’s latest version aligns with CSRD and the Taskforce on Nature-related Financial Disclosures (TNFD).

For companies operating in water-stressed regions, this kind of collaboration is a practical matter of operational survival. When multiple large users compete for a declining supply, tensions with local communities and regulators escalate. Companies that participate in collective water governance are far more likely to maintain the water access they need.

Move toward water positivity
The final step in the stewardship journey is contributing more to your local water system than you take from it. This is the most ambitious goal, and it’s still in early stages for most industries. But a growing number of large companies have made public commitments to become water positive within the next several years.

Water positivity means replenishing local water resources through conservation, watershed restoration and responsible reuse. It requires investing in the health of the natural systems, like wetlands, soil moisture and aquifer recharge zones that store and filter water.

Some of these investments involve technology. Treating and reusing wastewater at higher rates, using alternative water sources like treated municipal effluent or collected rainwater and implementing closed-loop systems all reduce the net draw on local freshwater supplies. Others involve broader environmental commitments, like restoring degraded wetlands or supporting reforestation in catchment areas to improve water retention.

Water positivity can’t be achieved by a single company working alone. It requires watershed-level collaboration extended into longer-term investments that benefit the entire local water system.
