Regional source context
NTMWD identifies Lavon Lake as its largest water source and lists member/customer communities across North Texas, including several cities ClrWtrCo serves.
DFW Water Quality Guide
What North Texas homeowners should know before buying a water system.
Dallas-Fort Worth water is usually safe to drink when it meets municipal standards, but safety is not the same thing as comfort, taste, scale prevention, or appliance protection. This guide explains the practical difference between water softening, whole-home filtration, and reverse osmosis for DFW homes.
Where much of North Texas water comes from
Many ClrWtrCo service-area cities are connected to North Texas Municipal Water District supply and treatment systems. NTMWD says Lavon Lake remains its largest water source, and Frisco says its treated water comes from NTMWD. Rockwall's consumer confidence report says Rockwall purchases treated water from NTMWD's Wylie Water Treatment Plant. Prosper also publishes local water quality resources and annual consumer confidence reports.
Local report context
Every city publishes water quality reporting differently. A free in-home test does not replace a municipal report, but it helps you understand what is happening at your tap.
Hard water
Hardness is mostly calcium and magnesium. In the home, it shows up as glass spotting, faucet scale, dry-feeling showers, stiff laundry, and mineral buildup inside water heaters.
Chlorine taste and odor
Municipal disinfectants are important for public water safety, but many homeowners dislike the taste, odor, and shower feel. Whole-home carbon filtration is commonly used for this concern.
Drinking water concerns
Reverse osmosis is usually installed at the kitchen sink for drinking water, coffee, cooking, and ice. It is often paired with whole-home filtration and softening.

Get your home tested
Municipal reports explain the public supply. Your fixtures, plumbing age, heater condition, and neighborhood distribution line can still affect what you experience at the tap. ClrWtrCo's free in-home test helps connect those dots.
