LaSalle outlines $4.38 million wastewater upgrades; lagoon sludge removal, SCADA and lift-station work planned

LaSalle held a public hearing on planned improvements to its wastewater treatment system that city staff said are intended to restore storage capacity, reduce operational problems caused by accumulated grit and debris, and modernize controls.

The project elements described include removal of roughly 40 years of accumulated sludge from the wastewater treatment plant storage lagoon, construction of a small building and process equipment for excess-flow disinfection, installation of a new collection box ahead of the headworks to capture grit and large debris, replacement of primary sludge pumps, and an upgrade to the wastewater SCADA system to improve monitoring and remote lift-station control. The presentation said much of the work will occur at the treatment plant and adjacent sludge lagoon, with upgrades at multiple remote lift stations.
