Littleton — LITTLETON – When a well system used to provide drinking water for horses failed on a hot day earlier this week, firefighters with South Metro Fire Rescue stepped up to help.

The well system at Zuma’s Rescue Ranch, 7745 N Moore Road, failed on Monday. Ranch staff were unable to reach a private water delivery company for help, so firefighters were called to the rescue.

Jodi Messenich, the organization's founder, told 9NEWS the firefighters came out in 15 minutes.

"I cried when they showed up," Messenich said.

About 45 thirsty horses were at the ranch, which serves as housing for rescued horses in different stages of rehabilitation.

A crew from Station 40 in Douglas County used water from their firetruck equipment to make sure the horses stayed hydrated until the well could be fixed.

Messenich says the ranch may need a new well, which would set the nonprofit back $25,000. Right now, the well is working and the horses have water, but Messenich worries the water can go out at any time.

In September, the ranch will be celebrating 10 years of service and will commemorate this with the "Rock the Ranch" event, emceed by 106.7 The Bull.
