Carrollton receives the majority of its water from NTMWD, one of the largest regional water authorities in Texas, with hardness levels that typically run between 14 and 17 grains per gallon. The city also supplements with Dallas Water Utilities supply during peak demand periods, but both sources deliver water well into the hard to very hard range. Water softener installation in Carrollton is among the most requested home improvement services in the area precisely because of how quickly hard water effects show up on fixtures and appliances.

Carrollton is primarily served by the North Texas Municipal Water District, with supplemental supply from Dallas Water Utilities during high-demand periods. Water hardness in the Carrollton system generally measures between 240 and 290 mg/L (14–17 GPG). Chloramine disinfection is used throughout both supply systems. The mix of two very hard water sources means Carrollton residents frequently encounter scale issues in dishwashers, coffee makers, and whole-home humidifiers common in the area.
