Lakeland Highlands Water Hardness & Quality Report (2026)

The City of Lakeland Department of Water Utilities is responsible for supplying water to Lakeland Highlands and other areas in Polk County, Florida. This utility serves approximately 197,051 residents through 63,916 metered accounts. The sole source of this water is the Floridan Aquifer, accessed via 19 deep groundwater wells. Of these, 13 are located at the T.B. Williams Water Treatment Plant, with the remaining 6 at the C.W. Combee Water Treatment Plant. Both facilities treat the water through filtration and softening processes before it enters the municipal distribution system. Lakeland Highlands receives this municipal supply directly, as it falls within Lakeland's city limits.

The Floridan Aquifer beneath Polk County is a significant geological feature, particularly the Upper Floridan Aquifer portion. This aquifer system is predominantly composed of Eocene and Oligocene-age limestone formations, such as the Ocala Limestone and Avon Park Formation. These rock layers are highly porous and permeable, featuring extensive dissolution features like sinkholes and caverns. Groundwater drawn from wells reaching about 750 feet deep has spent considerable time in contact with the bedrock, dissolving substantial amounts of calcium carbonate and magnesium. This prolonged interaction with the carbonate strata is what gives the water its characteristically hard profile, typical of limestone-dominated aquifers in the southeastern United States.

This consistently hard water can lead to noticeable scale buildup within household pipes, water heaters, and various fixtures. Such deposits not only reduce the efficiency of appliances like dishwashers and washing machines but can also shorten their lifespan, potentially increasing energy costs by as much as 20-30%. Homeowners often find that regular descaling with vinegar, the use of scale inhibitors, or employing rinse agents in dishwashers helps manage the issue. For significant hardness, installing a water softener is highly recommended. This can prevent appliance problems, extend equipment life, improve the lathering of soaps, and reduce spotting on dishes. The utility ensures compliance with drinking water standards, maintaining chlorine residuals for safety and regulating pH.
