Full report
Charlotte City Council has authorised a $3.999 million contract for replacement of the ultraviolet disinfection system at Charlotte Water's Irwin Creek Water Resource Recovery Facility.
Harper General Contractors was selected as the lowest responsive, responsible bidder following a six-bid procurement. Charlotte issued the invitation to bid on 15 July 2026. The award was included in the council's consent agenda, which was approved without any items being pulled for separate consideration.
The project will replace the facility's existing UV disinfection system. Charlotte Water said UV systems use ultraviolet light to neutralise harmful pathogens in wastewater effluent before it is safely discharged into the environment. The utility said the new system will increase efficiency in the wastewater-treatment process.
The work is expected to be complete in the third quarter of 2028 and will be funded through Charlotte Water's Capital Investment Plan.
The award comes alongside a broader set of utility and drainage approvals in the 12 October consent agenda, but the Irwin Creek contract is the principal wastewater-treatment investment. It provides for renewal of a treatment process directly associated with final effluent disinfection at one of Charlotte Water's resource recovery facilities.
