weather flow and/or low UV transmittance conditions. Additionally, the
existing UV equipment was commissioned in 1998 and is at the end of
its useful life. These conditions triggered the need to evaluate
disinfection equipment options to ensure that LTP has adequate
disinfection capacity up to 67 million gallons per day. Through various
analyses, the City determined that replacing the existing UV system with
a new UV system is the most feasible approach to address the capacity
and reliability deficiencies.
