The City of Arcata invites the community to a ribbon cutting ceremony for the completion of Phase One of the Arcata Wastewater Treatment Facilities Improvements Project on Wednesday, June 10.
This project, which originally broke ground in December of 2022, aims to improve and modernize Arcata’s world-renowned water treatment plant. Amongst other projects, improvements include the replacement of a chlorine gas disinfection system with a far more environmentally friendly ultraviolet system, major upgrades to electrical systems for digital control and underground piping and a complete renovation of the primary treatment headworks and clarifier.
The ribbon cutting ceremony, acknowledging the past three plus years of work by City staff, consultants and Wahlund Construction, will take place on Wednesday, June 10 at 4 p.m. meeting at the Wastewater Treatment Plant, 600 South G Street.
