What is Water Positive

Water positive means providing more water than you consume. With freshwater shortages becoming an issue around the world, companies are making various efforts to secure water.

There are two main ways to do it: either reduce consumption or increase supply.

There are ways to reduce water consumption, such as water conservation and recycling, and ways to increase water supply, such as investing in areas and businesses with high water stress, such as water scarcity and water pollution.

AWS Committed to Reducing Water Use in Data Centers

Amazon Web Services (AWS) is the new hyperscaler that has committed to making their business water positive.

At the AWS re:Invent event held in Las Vegas, the company announced a policy to achieve water positive by 2030, returning more water to the community than it uses directly in its operations.

AWS CEO Adam Selipsky said:

“Water scarcity is a major problem around the world, and with today’s announcement by Water Positive, we are committed to doing our part to help solve this fast-growing problem.

To ensure universal access to water, we need to develop new ways to conserve and reuse this precious resource. While we are proud of what we have achieved so far, we also believe that more can be done.

We are committed to leading water stewardship in our cloud business and giving back more water than we use in the communities in which we operate. We believe this is the right thing to do for the environment and our customers. ”

The company’s efforts to achieve this goal include: analyzing water usage in real time, using IoT technology to identify and fix leaks, using recycled or rainwater for cooling, and reusing water multiple times. It includes replenishment as well as reimbursement activities, including the availability of on-site water treatment systems, and where possible, funding for waterless cooling and various water replenishment activities at the facility.

In 2021, AWS said it achieved a global Water Use Efficiency (WUE) index of 0.25L water per kWh. In Ireland and Sweden, AWS says it doesn’t use water to cool its data centers 95% of the year.

According to a US Department of Energy report, the average evaporative cooling data center WUE is 1.8L per kWh.

In the UK, AWS is working with The Rivers Trust and Action for the River Kennet to create two wetlands on tributaries of the River Thames.

“England’s rivers are national treasures and we are delighted to partner with AWS and work with our member trusts here to protect the Thames and its tributaries,” said Mark Lloyd, CEO of The Rivers Trust. said.

“AWS’ commitment to be water positive by 2030 drives the actions needed to help restore rivers and water resources impacted by climate change.

We look forward to expanding our relationship with AWS and using this partnership to demonstrate similar avenues for other companies to jointly support water management activities that improve the resilience of rivers. ”

Data centers use a lot of water for cooling, but it’s not clear how much water the industry actually uses.

Researchers estimate that on average in the US, 1 MWh of data center energy consumption requires 7.1 cubic meters of water, but this can vary widely by region and facility.

Efforts of Google, Microsoft and Meta

Google, Meta and Microsoft have committed to being water positive by 2030, but many of their facilities now use millions of gallons of water per day.

Colocation and peering service provider CyrusOne, which owns and operates over 40 carrier-neutral data centers in North America, Europe and South America, claims several of its facilities are water positive. 

Morningstar Sustainalytics, a leading ESG research, ratings, and data provider that has helped investors around the world develop and implement responsible investment strategies, previously released a report showing that Microsoft is leading the market in water conservation efforts.

European data center operators pledged to the European Commission earlier this year to reduce water usage to up to 400ml per kWh of computer power by 2040.

Due to the effects of global warming and population growth, water shortages are becoming a problem around the world. We will continue to keep an eye on the water positive initiatives of major companies.
