Hillsboro Pool Service & Repair
Hillsboro sits apart from every other town we serve in one specific way: its water comes from the Brazos River basin, not the Trinity. The city buys treated water from the Aquilla Water Supply District, which pulls raw water from Lake Aquilla roughly 7 miles out under contract with the Brazos River Authority. A different source means a different starting point for the water in your pool, and that shapes how we set up your maintenance from the first visit on. A&M Pool Service & Repair runs weekly cleaning and equipment work across Hillsboro, about 30 miles south of our Waxahachie base, with cleaning and repair from $140.

What Lake Aquilla water means for your pool
Hillsboro is the Aquilla Water Supply District's largest customer, and a district official has put it at roughly 60 percent of the about 40,000 people the district serves. When you fill or top off a pool here, that water started in a Brazos basin reservoir and ran through the district's wholesale plant before reaching the city's distribution lines. We do not have published hardness, TDS, or pH figures for Hillsboro to quote, so we do not guess at them. We test your fill water in person on the first visit and balance from what the test actually shows.
Lake Aquilla has a source-water history worth knowing. The reservoir carried a documented atrazine problem, an agricultural herbicide that runs off farmland into the watershed. In the late 1990s finished water went over the federal limit, which led to a 1998 impaired-water listing and a TCEQ Total Maximum Daily Load for the lake that the EPA approved in 2002. The district added treatment, and atrazine was brought back down to safe levels. That history is about the raw source and the treatment that followed, and it is the reason we lead with testing rather than assumptions here.
Source water that runs harder leaves scale on the surfaces that heat and treat your water. On a salt system, mineral buildup coats the cell plates and drops chlorine output until the cell gets cleaned or replaced ahead of schedule. Inside a gas heater, scale settles on the heat exchanger and makes it work harder for the same temperature. We watch salt cells and Raypak and Sta-Rite heat exchangers closely on Hillsboro routes and adjust the cleaning interval to whatever the equipment is telling us.
Aging pipes and plants drove a roughly 50 million dollar Aquilla Water Supply District upgrade program, with Hillsboro rate increases that landed in 2024. Infrastructure work like that can shift how water reads at the tap over time, which is one more reason we retest rather than running on last year's numbers.
Common pool service calls in Hillsboro
- Salt cell scaling. Mineral buildup on the cell plates cuts chlorine output and shortens cell life. We inspect and clean on a schedule set to your water, not a generic calendar.
- Heater scale and short cycling. Scale on a heat exchanger raises run times and fuel use and can trip a heater into shutting down early. We check the exchanger and gas heaters during seasonal service.
- Clay movement at the pad and deck. Houston Black clay swells after rain and shrinks in drought, which moves equipment pads, cracks mastic joints, and stresses underground plumbing. We flag shifting before it becomes a leak.
- Freeze damage to exposed equipment. The February 2021 freeze showed how fast an unprotected pad can split here. We run freeze-guard checks and winterize pumps, filters, and exposed lines.

"Moved into a house with a neglected pool. A&M got it cleaned up, repaired the filter, and set us up on weekly service. Night and day difference."
Pool Service FAQ — Hillsboro
The City of Hillsboro buys treated water from the Aquilla Water Supply District, which draws raw water from Lake Aquilla in the Brazos River basin, about 7 miles from town. That makes Hillsboro the one community we serve on the Brazos rather than the Trinity.
The atrazine problem was a raw-source issue from the late 1990s that led to a TCEQ Total Maximum Daily Load and added treatment at the district, and atrazine was later brought down to safe levels. For your pool, it is a reason we test fill water in person instead of assuming numbers.
No. There are no published hardness, TDS, or pH figures for Hillsboro that we would stand behind, so we test your fill water on site and balance from the real reading.
