Five years after the Flint Water Crisis, Michigan city residents still don’t have access to clean water. So, Jaden Smith is using his company JUST water to help.

The eco-friendly bottled water company has teamed up with First Trinity Missionary Baptist Church to bring a mobile water filtration system to Flint called “The Water Box.”

The system will reduce lead and other contaminants found in the Flint water supply. The church has donated over five million water bottles to residents, but the donations have been declining. The Water Box was designed and engineered by Smith’s Just goods company and the church to hopefully provide some lasting relief.

JUST water was founded in 2015 by Smith and his famous father. Jada Pinkett Smith, DJ Jazzy Jeff, Lionel Richie, Queen Latifah and Calvin Harris are among the many notable names that are part of the collective.

The 20-year-old has been passionate about the environment his whole life and in the past year has extended the reach of recyclable JUST water bottles to the UK, several stores and in schools.
