During the construction of the project, a change order was issued for the addition of transformers, which were required to operate the ultra violet disinfection system, in the amount of $18,216.00. The total project cost was $569,594.20 (Attachment 4) which included engineering and additional Supervisory Control And Data Acquisition (SCADA) programing.

Upon acceptance by the City Council, the final payment will be processed and sent to the contractor. At that point, the two-year maintenance bond will begin if warranty work is needed.
