Garland receives its municipal water from Lake Ray Hubbard (which Garland owns and operates). These surface water sources pick up calcium and magnesium as they flow through North Texas limestone geology — the primary driver of the region's hard water problem.
According to the Garland Water Utilities Annual Water Quality Report, Garland water measures approximately 240–342 mg/L of total hardness, or 14–20 grains per gallon.
The real cost
Hard water damage is slow, invisible, and expensive. Here's what's happening right now in your home.
Scale coats the heating element first. At 20 GPG, expect 30–40% efficiency loss within 5 years and a lifespan cut from 12 years to 7 or less.
Replacement: $800–$1,500Mineral deposits on heating elements and spray arms reduce effectiveness. The white film on your glasses isn't fixable with more detergent — it's the water.
Extra detergent: $100+/yearCalcium clogs nozzles and builds visible crust on fixtures. Showerhead pressure drops noticeably within a year at 20 GPG.
Fixture replacement: $50–$300 eachHard water reduces detergent effectiveness by up to 50% and traps minerals in fabric fibers — causing stiffness, fading, and faster wear.
Higher detergent use + shorter garment lifeCalcium and magnesium interfere with soap lather, leaving a residue film on skin. Dry skin and dull hair after showering is a direct symptom of Garland's water.
Real but hard to put a dollar onJust 1/4 inch of scale on a water heater element reduces efficiency by up to 40%. Your water heater is likely your home's biggest energy user — and hardest working.
Up to $400/year in wasted energyWhat actually works
The right fix depends on your home, household size, and water usage. A free water test helps determine which makes sense.

Common questions
Garland tap water measures approximately 14–20 grains per gallon (240–342 mg/L), sourced from Lake Ray Hubbard (which Garland owns and operates). This puts Garland firmly in the "very hard" category — the EPA classifies anything above 10.5 GPG as very hard, and Garland exceeds that. You can verify current readings in the Garland Water Utilities Annual Water Quality Report, published annually.
Yes. Garland water meets all federal safety standards and poses no health risk. Calcium and magnesium — the minerals that make water hard — are not harmful to consume. The problem is what they do to your home: scale deposits in appliances, pipes, and fixtures that reduce efficiency and shorten lifespan over years.
Yes — salt-based water softeners are highly effective on North Texas water. At 14–20 GPG, you'll want a system properly sized for your household. Most Garland homeowners notice results within days of installation: dishes come out spot-free, showers feel different, and fixtures stop accumulating crust.
It depends on your home's size, how hard your water is, and which system you choose. The best way to get an accurate number is a free in-home water test — we'll measure your Garland water and give you a clear, no-obligation quote. Most homeowners recoup the investment through extended appliance life within a few years.
A water softener removes hardness minerals (calcium and magnesium) through ion exchange. A water filter removes contaminants like chlorine, sediment, or organic compounds. They solve different problems. Most Garland homeowners benefit from a softener for the whole house, plus an under-sink RO system for drinking and cooking water.
Generally no permit is required for residential water softener installation in Garland. We use licensed, insured local plumbers for all installations — this protects your appliance warranties and ensures compliance with Dallas County plumbing codes.
