LAKEPORT, Calif. – The Lakeport City Council has approved a construction contract for the sodium hypochlorite upgrade project at the City’s Wastewater Treatment Plant, an infrastructure improvement focused on enhancing employee safety and strengthening day-to-day operational reliability.

The approved project replaces the facility’s existing chlorine gas disinfection system with a liquid sodium hypochlorite system, reducing the risks associated with storing and handling pressurized chemicals. 

Liquid systems also allow for more consistent and reliable disinfection operations and reduce operational constraints associated with gas-based systems.

The city awarded the construction contract to Piazza Construction, the lowest responsible bidder, in an amount not to exceed $970,200, which includes a contingency for unforeseen conditions. 

Construction is expected to begin in March and conclude by August.

“This upgrade represents an important investment in employee safety and essential infrastructure,” said Utilities Director Paul Harris. “Transitioning to a liquid disinfection system improves operational reliability while reducing potential hazards at the treatment facility.”

The project is fully budgeted within the city’s sewer operations and maintenance fund. 

Officials said it qualifies for a California Environmental Quality Act categorical exemption as a minor alteration and replacement of an existing public utility system with no expansion of treatment capacity.

The city’s announcement on the project said it supports City Council priorities related to public safety, fiscal stability and capital infrastructure maintenance.
