Tech billionaire Elon Musk has kept his word, recently donating almost half-a-million dollars to Flint Community Schools to provide children with clean drinking water and safer fountains for students, according to a press release from the city.

Back in July, the Tesla CEO tweeted that he would commit to funding the repair of “water in any house in Flint that has water contamination above FDA levels. No kidding.”

Three months later, Musk has donated $480,350 to assist Flint schools in installing new ultraviolet water filtration systems.

“This donation comes as a group within the Flint Community Schools continues to work tirelessly to devise a long-term solution to the challenge of clean water that has plagued the community for the past four years,” reads the press release.

“We are deeply grateful for the generosity and the budding partnership between Flint Community Schools, the Musk Foundation and Elon Musk,” said Derrick Lopez, Flint Community Schools Superintendent. “The new water filtration systems will be instrumental in helping our students return to the normalcy of what should be a fundamental right: having access to safe, clean water from water fountains in their school.”

“I am truly humbled by the generosity and the budding relationship between Mr. Musk and Flint schools, led by superintendent Derrick Lopez,” said Flint Mayor Karen Weaver. “After conversations with Mr. Musk’s team about several challenges our city is still facing, and this was one of them, we appreciated them providing an opportunity for a sense of normalcy to be returned to our children, which are our most precious resource. “
