Lewisville sits directly on the banks of Lake Lewisville, one of the city's primary water sources, yet that proximity does not make the water any softer, with hardness levels typically running between 13 and 16 grains per gallon. The dissolved mineral content in the lake is a reflection of the regional geology rather than the treatment process, meaning no amount of standard filtration removes hardness without an actual softener. Water softener installation in Lewisville is among the most effective steps homeowners can take to extend the life of their water-using appliances.

Lewisville is served by the Upper Trinity Regional Water District, drawing treated surface water from Lake Lewisville and Lake Ray Roberts. Hardness in the Lewisville system generally runs between 220 and 275 mg/L (13–16 GPG), placing it in the very hard category. The utility uses chloramine disinfection in its distribution system. Lewisville's continued growth has added thousands of new residential connections in recent years, and hard water effects in newer subdivisions are identical to those in established neighborhoods.
