Diamond Water issues boil notice for upscale community near Bulverde

Residents of Rim Rock Ranch subdivision, located just off FM 1863 between Oak Village North and the Cibolo Creek, have had to boil their drinking water after being notified last week by Diamond Water Company that a contaminant had been detected at the subdivision's well site.

Rim Rock Ranch is not located within the Bulverde city limits.

Southwest Water Co., which is headquartered in Los Angeles, Calif., purchased Diamond Water in May 2007.

“Earlier this month, we received an inconclusive test of the treated water,” said Delise Keim, vice president of communications for Southwest Water Co. “As a responsible purveyor of water, we issued a precautionary boil water notice and increased the amount of chlorine.

“At no time did the contaminant make it's way into the distribution system. The contaminant was found at the well site.”

Keim said the water leaves the well and goes into a storage facility where it is treated, tested, and released into the distribution lines.

“We have not released any water into the lines that has not tested safe to drink,” she said.

Test samples found coliform bacteria, but after treating the water test samples were negative.

“But it's still very important that residents comply with the boil water notice,” Keim said.

According to Keim, about 350 homes have been notified to boil water until the problem has been resolved.
