World Water Day 2019: Engineering Sustainable Water for All

March 22 is United Nations World Water Day. The 2019 theme “Leaving No One Behind” echoes the UN’s Sustainable Development Goal 6 (SDG 6), which includes a target to ensure availability and sustainable management of water for all by 2030.

World Water Day recognizes the human right to water, which entitles everyone, without discrimination, to sufficient, safe, acceptable, physically accessible, and affordable water for personal and domestic use; which includes water for drinking, personal sanitation, washing of clothes, food preparation, and personal and household hygiene.

GAI’s Water Group is an integrated team focused on sustainable engineering solutions that help manage all forms of water and provide safe, sustainable, and affordable water solutions to municipalities and industry. GAI Water Group leaders speak about how their work helps support the World Water Day theme.


Alex Makled“Water is a precious resource that we often take for granted. The collective brainpower of water engineers has enabled the affordable recovery of usable water from a variety of historically unavailable sources, but that water must be used responsibly for all to benefit. Proper management that helps ensure adequate water for all who need it can go a long way toward lessening suffering, poverty, and conflict around the world.”

Khalil Atasi“Advances in wastewater treatment empower us to go far beyond merely ‘cleaning up the mess.’ Today’s state-of-the-art Water Resource Recovery Facilities yield valuable nutrients for industry and farming, sources of renewable green energy, and the potable water necessary to help mitigate shortages of water.”

Jill Grimaldi“Working to identify alternative water sources is a constant challenge. Whether we’re meeting demand by drawing water from deep aquifers or deploying innovative treatment technologies for surface water, people everywhere benefit as we develop new and better approaches to providing sustainable water supplies.”

“Water is one of the most plentiful resources on Earth, yet the potable portion is very limited. In some parts of the world, people can spend hours every day trying to source usable water for their families. When we develop solutions to upgrade the quality of water and keep it the ecosystem, we help minimize waste and maximize ample water supply for all.”

Shannon Killion“History shows that access to clean water plays a central role in helping communities reach their highest potential. By helping build affordable and effective solutions for water treatment and managing stormwater and wastewater, my work helps protect human health so more people around the world can thrive.”

David Troianos“Developing solutions that improve the quality of source drinking water by controlling and limiting wastewater discharges to regional waterways is a challenge that we face every day—and it’s important to note that the strategies we develop locally contribute to best practices that can be applied in many places around the world.”
