The survey finds that 75% of respondents intend to achieve greenhouse gas (GHG) reduction goals by 2040 or earlier. 48% of respondents have set a net-zero emissions goal, and 42% have set an emissions reduction goal.
“The water sector has an important role in the global effort to reduce GHG emissions,” said Patrick Decker, president and CEO at Xylem. “Our sector is energy intensive. However, smart application of technology makes it possible to manage water far more efficiently and affordably. Increasingly, utilities are finding ways to deploy technology to become more resilient and reduce emissions, while also addressing many of their operational concerns.”
In Europe, 31% of respondents plan on installing more energy-efficient technologies. Others are leveraging digital solutions, with 29% looking into advanced metering infrastructure (AMI) and leak detection solutions, and 24% turning to treatment system optimization technologies. Similarly in North America, 35% of respondents plan on implementing plant or asset optimization technologies to advance their decarbonization goals.
With 37% of North American respondents citing resilience to extreme storms and floods as a major concern, advanced digital solutions are also helping water managers improve operational and environmental outcomes at an affordable cost. Buffalo Sewer Authority (BSA) in the US, for example, saved US$145 million by deploying a smart sewer system that reduced polluted water flowing into its rivers during storm events – solving a longstanding problem without spending on new infrastructure.
Many utilities ranked process emissions – such as methane and nitrous oxide – close to last in their priorities for action, despite their significant impact, showing that a better understanding of this issue and technological innovation are needed to tackle total water-sector emissions.
