Celina, Texas's Home for Water Softeners, Water Filters,
& Water Delivery

Yes, Celina’s tap water meets state and federal drinking water standards. However, meeting legal standards does not mean the water is completely free of minerals, disinfectants, disinfection byproducts, or trace contaminants. Many homeowners still choose water treatment to improve taste, reduce buildup, and add another layer of protection at the tap.

Celina purchases surface water from Upper Trinity Regional Water District. Upper Trinity provides treated water to communities and utilities across Denton and Collin Counties. Celina’s water comes from Lake Lewisville and Lake Chapman, with treatment handled at Upper Trinity’s Tom Taylor Water Treatment Plant in Lewisville and Tom Harpool Water Treatment Plant in Providence Village.

Celina water contains hardness minerals, including calcium and magnesium, which can contribute to scale buildup and spotting. While the water quality report did not show a total hardness number, the presence of minerals such as calcium, alkalinity, and dissolved solids can still affect how water performs throughout the home. A home water test can confirm the exact hardness level at the tap.

Yes. Celina uses chloramines as a disinfectant. The average chloramine level was 2.10 ppm, with a detected range of 0.50 to 3.35 ppm. Chloramines help protect water as it moves through the distribution system, but they can affect taste, odor, and the way water feels on skin and hair.

Yes. Disinfection byproducts can form when disinfectants react with naturally occurring organic material in the water. In Celina, detected levels included:

Haloacetic Acids (HAA5): 25 ppb

Total Trihalomethanes (TTHM): 44 ppb

These levels were within regulatory limits, but many homeowners still choose filtration to reduce long-term exposure and improve drinking water taste.

Celina water contained several inorganic substances, including:

Arsenic: 1.2 ppb

Barium: 0.047 ppm

Bromate: 11 ppb

Chromium: 1.1 ppb

Cyanide: 0.13 ppm

Fluoride: 0.26 ppm

Nitrate as N: 0.61 ppm

These levels did not exceed federal limits, but they help show what can be present and still lingering in the local water supply.

Yes, lead and copper were detected in recent sampling. Copper had a 90th percentile level of 0.317 ppm, with 0 sites over the action level. Lead had a 90th percentile level of 1.77 ppb, also with 0 sites over the action level. Lead and copper can enter drinking water through plumbing, fixtures, or service lines, so a home water test is the best way to understand conditions at the tap.

Celina water contained additional substances within regulatory limits, including:

Beta/photon emitters: 4.2 pCi/L

Atrazine: 0.3 ppb

Metolachlor: 0.2 ppb

Nitrate as nitrogen: 0.202 ppm highest level detected

These values were within regulatory limits, but some homeowners still choose filtration for added protection and better taste.

Many Celina homes can benefit from a water softener if hardness minerals are causing scale, spots, poor soap lather, or buildup on fixtures and appliances. A water softener can help protect plumbing, improve cleaning, and reduce mineral residue throughout the home.

A water filter can help Celina homeowners address chloramine taste and odor, disinfection byproducts, trace inorganic substances, and overall drinking water quality. Whole-home filtration can improve water throughout the house, while reverse osmosis is often used for cleaner, better-tasting drinking water at the kitchen sink.
