This contract is for the installation of the pumps, piping and instrumentation necessary to dose the primary sedimentation tanks with sodium hypochlorite during the planned secondary outages associated with construction of certain aspects of the North End Plant Expansion project to be able to maintain NPDES permit compliance.
Sodium hypochlorite will be pumped through the existing utility tunnel from the temporary chemical storage tanks to the influent channel of the primary sedimentation tanks. A residual chlorine analyzer will be installed in the primary sedimentation tank effluent channel to control the sodium bisulfite dichlorination process before the water is discharged to the river.
