Testing continues on new Campbell River siren system - Campbell River Mirror


BC Hydro’s contractor continues to work via the set up of the brand new public warning system as a part of the John Hart Producing Station Alternative Undertaking.
There was a technical challenge that has now been resolved following the siren checks on Aug. 28. The following full siren system take a look at, to happen intermittently over the day, is about to happen on Sept. 17 from 9 a.m. to five p.m.
BC Hydro has sirens in place from the John Hart Dam all the way down to Second Island, which is a kilometre or so downstream of the brand new John Hart underground powerhouse tunnel outlet.
BC Hydro says there’s sometimes questions in the neighborhood when the sirens go off on the distinction between warning individuals about river movement modifications versus the security of the upstream dams.
“The sirens are solely supposed to supply facility operational warnings of sudden water movement modifications or unplanned water movement modifications from the dam’s spillway gates or low stage shops, or from the powerhouse tunnel outlet,” mentioned BC Hydro spokesperson, Stephen Watson. “This warning is for people who find themselves throughout the river channel both swimming, fishing, rafting, kayaking, or strolling or standing close to the water movement. The sirens, which have a whooping sound, advise individuals to maneuver out of the river channel instantly till the elevated water movement passes by.”
BC Hydro says as soon as the brand new siren system is accepted and in place, they may sometimes take a look at the system to proceed to make sure it’s working as supposed. BC Hydro will notify the group when the brand new sirens are formally commissioned.
“We respect individuals’s endurance as we work via the testing interval,” says Watson. “It’s crucial that all of them work as designed. Whereas we attempt to notify individuals of the deliberate checks, we additionally should be clear that there’s a uncommon likelihood of an unplanned water movement occasion from the John Hart facility throughout a take a look at. When the sirens are heard throughout a deliberate take a look at, individuals ought to transfer out of the river channel. On Sept. 17, it might be finest to avoid the Campbell River and do different actions.”
As for the three upstream hydroelectric dams, Watson says day-to-day. the dams are secure and BC Hydro has an in depth Dam Security Program, together with ongoing monitoring. He added it is just a extreme earthquake that would put the upstream dams in danger, and that’s why BC Hydro, the Metropolis of Campbell River, and Strathcona Regional District developed a ‘If it knocks you down, go to excessive floor’ message. The extreme floor shaking is the one warning individuals could obtain, because the sirens are usually not an earthquake or dam consciousness warning system.
BC Hydro has a collection of proposed seismic improve initiatives in any respect three dams which will all start as early as 2023/2024. This contains the John Hart Dam Seismic Improve Undertaking in order that it may well face up to a extreme earthquake.
