The City of Mapleton, UT has received customer complaints over the years pertaining to drinking water taste, odor and color. As the City has continued to grow, water quality concerns have arisen as well pumping durations have increased. The City and J-U-B Engineers conducted a water quality assessment, characterizing risk and developing strategies to mitigate water quality risks.
A water sampling plan was developed at strategic locations in the distribution system. The analysis of the results focused first on source water chemistry and then on distribution system dynamics. The AWWA M68 manual was the guiding document through the assessment.
Being able to correlate customer complaints to operational conditions began to tell a story that suggests there is potential for differing source chemistry that impact taste, odor and color. There was no one single water quality parameter that can be attributed to customer complaints. Rather, awareness of source water interaction and how that source moves through the water distribution system provided a complete story. Data management and operations and maintenance strategies were recommended as the highest value solutions. The governing objective going forward is to proactively address water quality risk regarding customer confidence, that manifests in taste, odor and color concerns.
