Midlothian Pool Service & Repair
The right pool care in Midlothian depends on your address, because the water here arrives from more than one place. The City of Midlothian runs two treatment plants, and properties outside the city limits often draw a different supply entirely. We service homes inside the city limits and out on the well-blended water past the edge of town, reading what your fill water is doing to your equipment and your surfaces before we build the maintenance around it. Weekly cleaning and equipment repair start at $140, and you work with the same crew each visit.
Local Knowledge. Proven Results.
- We track which Midlothian addresses sit on city water versus Sardis-Lone Elm well-blended supply
- We account for the 3.25 ppm chloramine residual in the city's 2025 water when balancing your pool
- We service homes near the Tayman and Auger plant service areas and out past the city limits
- Based in Waxahachie, about 12 miles from Midlothian, so we are close enough to respond
What Two Water Sources Mean for Your Pool
The City of Midlothian (PWS TX0700005) treats water at two plants. The Tayman Plant treats Joe Pool Lake water through the Trinity River Authority. The Auger Plant is a low-pressure microfiltration membrane plant that came online in 2013 and expanded to 24 MGD in 2024, treating Richland-Chambers and Cedar Creek water through the Tarrant Regional Water District. The city's older groundwater wells have been plugged and abandoned. Inside the city, you are filling with treated surface water.
That city water carries a chloramine residual, reported at 3.25 ppm in 2025 with a range of 3.01 to 3.4. Chloramine behaves differently from free chlorine in a pool. It holds steadier in the long summer heat, but it also means we watch your combined chlorine and shock the water when readings climb, especially during the stretch of 95-degree afternoons when sanitizer demand runs high and evaporation pulls your levels around.
Homes outside the city limits are a different story. Many sit on Sardis-Lone Elm WSC, which blends Trinity Aquifer wells near 2,500 feet and Woodbine Aquifer wells near 800 feet with purchased treated surface water. Groundwater carries more dissolved minerals than the city's surface supply, so pools on the well-blended water tend to scale faster on tile and salt cells. If you are on that supply, we check the cell and the heater more closely and stay ahead of the buildup before it costs you a part.
This split is real and it tracks with the address. We do not assume one routine covers every Midlothian pool. We look at where your water comes from first.
Common pool service calls in Midlothian
- Scale on salt cells. On the well-blended water outside the city, dissolved minerals plate out on cell plates and tile faster. We inspect and clean the cell on a schedule that matches your supply instead of waiting for the salt system to throw a fault.
- Chloramine and chlorine demand. City water arrives with a chloramine residual, and combined chlorine builds when bather load and heat stack up. We test for it and shock when the numbers call for it.
- Clay movement on the pad and deck. The Houston Black clay under Midlothian heaves in wet spells and contracts in dry ones, which works on coping, mastic joints, and the plumbing at your equipment pad. We watch for shifting and cracked mastic before a leak starts.
- Freeze damage to equipment. The February 2021 freeze put the whole county on notice about hard cold. We run freeze-guard checks and winterize the pad so pumps and filters survive the cold snaps.

What Midlothian Customers Say
"Our pump died on a Friday afternoon in July. A&M had a tech out the next morning and we were back up and running by lunch. Honest pricing, no pressure."
Pool Service FAQ — Midlothian
Address and water source. Homes inside the city fill with treated surface water from the Tayman and Auger plants. Homes outside the limits often draw Sardis-Lone Elm well-blended water, which carries more dissolved minerals and scales tile and salt cells faster.
The city does not publish hardness, TDS, or pH for its supply, so we will not quote a number we cannot stand behind. What we can tell you is the city reports a chloramine residual of 3.25 ppm in 2025, and we balance and sanitize around that.
Yes. We service pools on the well-blended Sardis-Lone Elm supply on the outskirts as well as homes inside the city, and we adjust the routine to match which water you actually have.
