SEWER ALARM MODIFIED T.O. HOPES TO PREVENT REPEAT OF MARCH RELEASE.Byline: Cecilia Chan Staff Writer THOUSAND OAKS Thousand Oaks, residential city (1990 pop. 104,352), Ventura co., S Calif., in a farm area; inc. 1964. Avocados, citrus, vegetables, strawberries, and nursery products are grown. - The city has made changes to the Hill Canyon Treatment Plant's alarm system to safeguard against a repeat of the mechanical failure that discharged 1.7 million gallons of nonchlorinated sewage Sewage Water-carried wastes, in either solution or suspension, that flow away from a community. Also known as wastewater flows, sewage is the used water supply of the community. It is more than 99. into Conejo Creek, according a report released Tuesday. An alarm that provides around-the-clock coverage will alert city employees on standby standby Medtalk adjective Referring to the immediate availability of a certain specialist–anesthesiologist, surgeon, who can be deployed in a medical emergency. Cf Concurrent. via the telephone if a future failure were to occur, the report said. In the March 31 incident, filtered sewage flowed without proper chlorine chlorine (klōr`ēn, klôr`–) [Gr.,=green], gaseous chemical element; symbol Cl; at. no. 17; at. wt. 35.453; m.p. −100.98°C;; b.p. −34.6°C;; density 3.2 grams per liter at STP; valence −1, +1, +3, +5, +7. treatment from 2:45 to 6:15 a.m., and the city did not discover the discharge until April 5. Athough the sewage had been filtered, the release prompted concern from the Ventura County Environmental Health Division about possible pathogens in the water in the 72 hours after the release. ``There are standards in the industry and we already have those standards in place,'' said Chuck Rogers, the city wastewater superintendent who authored the report. Mike Byrne of the county environmental health division had not yet seen the report and could not comment. The city's report was forwarded to the state Water Quality Control Board, which is reviewing the incident. The agency has the authority to impose fines. A mechanical problem with a system pump failed to deliver the required dose of chlorine to the filtered sewage, officials said. ``Additional safety measures safety measures, n.pl actions (e.g., use of glasses, face masks) taken to protect patients and office personnel from such known hazards as particles and aerosols from high-speed rotary instruments, mercury vapor, radiation exposure, anesthetic and were planned and were installed on April 7 which monitor'' the chlorine, the report said. ``This improvement will ensure that an adequate chlorine residual is always present in the chlorine contact chamber. Additionally, the failure of any delivery pump was tied to the overall plant alarm network which provides 7 day/24 hour coverage and direct contact with city standby employees.'' The city also supplied regulatory agencies regulatory agency Independent government commission charged by the legislature with setting and enforcing standards for specific industries in the private sector. The concept was invented by the U.S. with a letter from a civil and environmental engineering professor that concluded that even without the chlorine, the filtration at the plant would have removed almost all the virus from the sewage.
