Approximately 1,420 customers in Hope Ranch have had to boil their water for drinking and cooking since Friday after a water main break.

La Cumbre Mutual Water Company issued a boil water notice on Saturday for all of Hope Ranch, excluding Bithyina Road, Silvestre Road, Sonriente Road, Cuervo Avenue, Corta Road, Cantera Avenue, Cresta Avenue, and Via Abrigada.

Alex Rodriguez, president of the company’s board of directors , said a tree fell over and hit a pipe, causing the water main break.

The pipe connects to La Cumbre Water’s largest reservoir, which serves a majority of residents in Hope Ranch, and it’s estimated that a third of customers were affected, Rodriguez said.

The boil water advisory is a standard precaution, he said. The California State Water Resources Control Board has to ensure repairs and bacterial testing are completed before the advisory can be lifted.

Two tests have to be done before they lift the advisory, Rodriguez said, and the water company expects the results of the second test Wednesday afternoon. If everything is cleared, residents will be able to use their water as normal.

“We don’t expect these kinds of disruptions in our infrastructure, but unfortunately, accidents do happen,” Rodriguez said. “We’re going to do our best to make sure that something like this doesn’t happen again.”

Crews stayed up all night from Friday to Saturday morning in order to fix the water main break. They did have to drain the reservoir because water pressure was so strong that they couldn’t turn off the water valves, Rodriguez said.

Crews then had to refill the reservoir so that there would be enough pressure for the homes that were affected by the shut-off to start receiving water again.

Affected residents are advised to only use boiled tap water or bottled water for drinking and cooking purposes as a safety precaution to avoid stomach or intestinal illness.
