When summer really heats up, one thing is on everyone’s mind: water. From swimming in pools or the ocean, to sweating (lots), and drinking tons of extra H20, there is no other season where water’s importance feels so obvious.

For those of us who think of water as something that comes cleanly and safely out of the tap, it can be all too easy to take it for granted. Unfortunately today, 1 out 10 people in the world live without access to sanitary drinking water. But there are lots of organizations out there working to change that! Like these great non-profits below. Each of them understands the primal and primary importance water plays in all of our lives, and work to ensure that all people have access to it. Find out more and support their great work!

Charity: Water One of the best known water orgs, the good folks at Charity: Water work to bring clean drinking water to people in developing nations. So far, it has funded more than 6,000 projects in 20 countries worldwide.

Water.org: In 1990, an organization called WaterPartners International began its efforts to bring sanitary, safe water to communities in Africa, South Asia, and Central America. In 2009, they merged with H20 Africa (founded by Matt Damon), and continue to work with local partners to make the biggest impact possible.

Miya Water: Founded by Shari Aronson, an Israeli businesswoman and philanthropist, Miya helps ensure the “abundance of fresh water through efficient management of our cities’ existing fresh water resources.” They partner with utility companies to design technological solutions to help up water efficiency.

WaterAid America: This internationally-focused non profit works to improve access to safe water, hygiene, and toilets in the world’s poorest communities. Their current #girlstrong campaign is helping to unlock the potential of 5,000 girls to make a difference.

Water is Life: This organization focuses on providing both clean drinking water and hygiene education programs to schools and villages in need. They also created the Water is Life straw, an ingeniously small and portable drinking straw with a built in filtration system that renders any water it is immersed in clean.

Water Without Borders: This organization was “created from the understanding that lack of safe drinking water is the leading cause of disease, civil strife, hunger, and birth defects in the world.” To date, they have worked with communities in South Dakota, Africa, Haiti, and Honduras to enable the creation of sustainable sources of safe drinking water.
