Maumelle Water Hardness & Quality Report (2026)

Maumelle Water Corporation serves approximately 2,832 residents in the city of Maumelle, Pulaski County, Arkansas. The utility sources its supply from two surface water reservoirs: Lake Maumelle (8,900 acres, max depth 45 feet) and Lake Winona (1,240 acres), both feeding into Jackson Reservoir for regulation before conventional surface water treatment. Central Arkansas Water also draws from these lakes for regional distribution, and the utility can be reached at P.O. Box 65, Roland, AR 72135.

The watershed encompasses the upper Arkansas River basin within the Ouachita Mountains, with Lake Maumelle and Lake Winona impounded on Maumelle River tributaries. Paleozoic bedrock includes shales, sandstones, and minor limestones, lacking extensive carbonate platforms or karst aquifers. The soft water character arises from low mineral pickup in this non-calcareous terrain—dominated by the Arkansas Novaculite Formation and Ordovician-Silurian siliceous rocks—resulting in naturally low dissolved solids shaped by surface runoff rather than groundwater aquifer contact.

As soft water, Maumelle's supply causes minimal scaling on fixtures, pipes, or appliances, reducing buildup in water heaters, dishwashers, and washing machines. No significant limescale maintenance is required, though corrosion risk may be slightly higher without protective minerals—monitor for pinhole leaks in copper plumbing. A water softener is unnecessary and not recommended, as it could overly strip beneficial minerals; focus on point-of-use filtration if aesthetic concerns arise. The utility earns an 'A' compliance grade with zero violations since 2023, employing conventional filtration and disinfection for surface water treatment.
