Progress Towards Operating Conditions
City leadership has worked with operators and engineers to identify what is need to restore operating condition. Part way through the process new engineers were hired and an insurance claim filed to support recovery work. Every electrical panel had to be rewired, all of the motors and pumps needed to be replaced throughout the entire plant. All surfaces needed to be cleaned and sterilized. Initial from professional advice we thought the membranes would be able to be restored to get the plant operational. Unfortunately, this was not the case and wasn’t discovered until the original anticipated date. Upon this realization it was discovered that membranes are over 8 months delayed at the manufacturer. This timing was as we were entering winter 2025-2026 and called for the need to continue operating in emergency mode. Our continued diligently working within their ability and resources sanitize and keep operations functioning the best the situation provides.
Emergency Operation
The plant has been in emergency operation since the plant failure. The use of the lagoons has been the primary source for the plant since the failure. This extreme use of the backup system is taking it’s toll.
