Water Treatment Plant Upgrade and Expansion Project
New Ozone Disinfection System
Safety Alarm Testing ― February 2010
Starting approximately February 12, the construction team is testing and implementing the new ozone disinfection system safety alarms. These alarms ensure safe operation of the plant and alert employees to matters needing attention. Alarms may be heard outside the ozone building at the plant during construction working hours, weekdays, from 7 a.m. to 5 p.m.
The outdoor alarm volume will be lowered and muffled as much as possible. At certain times, the alarms will need to be tested at full volume. There is no danger to the community or to the drinking water when the alarms are activated. The water will be perfectly safe to drink.
Starting approximately February 17, crews will begin the start-up phase of the ozone disinfection equipment. This will continue through April. During this start-up phase, muffled and full volume alarms may be heard during normal construction working hours, weekdays, from 7 a.m. to 5 p.m., or possibly after hours.
