City of Arcata adds UV Disinfection to wastewater system


Arcata, Ca., (KIEM) The City of Arcata Community Development Department has been awarded with a $5 million Community Development Block Grant (CDBG) from the California State Department of Housing and Community Development. Majority of CBDG funding will be used to make upgrades to the city’s wastewater treatment facility.

“We are switching over from our current chlorine disinfection to UV, which is an ultraviolet high-density disinfection system,” Deputy Director, Mike Clinton said.

With the new system, a high density light will penetrate the wastewater and kill harmful organisms. Switching to UV lights are beneficial to the environment, department employees, and community.

“It will eliminate the need for increased ratepayer revenue” said Clinton.

Now, all there is left to do is wait for the department to start the UV light installation.

“Right now we are in contract with a couple of engineer firms,” said Clinton. “They’re supposed to wrap up the pre-design in August.”

Mike Clinton said no one has been impacted by current water conditions thus far.
