Priority

Description An engineering study of dissolved nutrient removal from source water (nitrates, polyfluoroalkyl compounds, mycrositins, etc...), the long-term financial and environmental sustainability of lime softening, and filter system valving and build-out based on the study results. Justification Regulations on dissolved ions in source and finished water are changing with federal administrations and increasing evidence of chemcial toxicity which will result in a need to have treatment technologies capable of ionic removal. Further quicklime and lime solids management costs have continued to increase yearly and a cost/benefite analysis of lime softening is warranted while investigating treatment technologies. The filters may need modification to accommodate new technologies. This is a study and will inform future CIP, including five projects on the unfunded list - Nutrient Removal, WTP Filter #6 Buildout, Water Plant Softener Improvements, Soda Ash Replacement, and Lime Lagoon Outlet Structure Modifications.
