When contractors did some test runs early this month on a series of blowers designed to spray brine across the holding pond for residual liquid from Cambria’s new emergency water-supply project, some people called the services district to complain that the process was unusually loud.
Because the plant wasn’t yet operating, the tests were done with rainwater that had accumulated in the pond, according to Cambria Community Services District officials.
It wasn’t just the noise from the blowers that was disturbing neighbors and others, especially those accustomed to the area’s normally quiet environment. But neighbor Leslie Rich-ards said an intermittent air-horn-like screech had so alarmed her horses that one of startled animals ran into a wall and seriously injured its eye.
Tom Gray, spokesman for the CCSD, said District Engineer Bob Gresens and Randy Redmann of CDM Constructors had responded “within an hour” to the complaints.

“They were able to determine that the main cause (of the noise) was two air compressor tanks that had automated condensate blow-off valves,” Gray wrote in an emailed response. “Redmann has since ordered the necessary noise reduction snubbers to go on the vent pipeline. He also shut off the automated valve-opening feature that same day."
