in partnership with Citizens' Environmental Coalition

and featuring Houston Public Works Water Works Festival

This year’s Green Mountain Energy Earth Day will feature the Houston Public Works’ popular Water Works Festival.

Saturday, April 22

12 – 5 pm


This year’s Green Mountain Energy Earth Day theme is water. As a central environmental issue, the proper care and management of Houston’s water is a topic that affects everyone. The city’s present and future relies on it.

The Water Works Festival will bring their interactive exhibits to Discovery Green to educate families about this vital natural resource. Expect family-friendly performances, live music, art installations, face painting, crafts and activities. Educational talks, panel discussions, spoken word performances and more will be provided. And, of course, there will be plenty of time to enjoy the water features at Discovery Green.

Exhibitor applications now being accepted!

Early bird pricing is available until March 22 extended through April 7!

Volunteers needed! If you’re interested in becoming a volunteer please read the information here. 


Sponsorship opportunities are also available, please contact Stephanie Carroll at for more information.

This will be a zero-waste event. Please plan on bringing your own refillable water bottles and utensils.

Exhibitors will be asked to ensure waste is minimized by only providing reusable or compostable items

Jones Lawn

The Jones Lawn is the largest green space at Discovery Green®, and therefore offers panoramic views of the Park and unobstructed views of the downtown skyline. The Lawn is an exceptional manicured space that can accommodate almost any large gathering. It is the site of major events such as Discovery Green’s festivals or pick-up sports. The Convention District Garage lies directly below the Jones Lawn. From charity galas, festivals or concerts for hundreds or thousands, the Jones Lawn can make any event a memorable and magical occasion.
