Water treatment in Spicewood, TX depends entirely on which of the area's many small systems you are on. Spicewood is not one water system. It is more than a dozen.
There is no city hall here and no city utility. What the 78669 ZIP has instead is a patchwork: more than a dozen small public water systems, split about evenly between Lake Travis surface-water plants and Trinity or Ellenburger well fields, plus thousands of private wells on lots that run from one acre to twenty-five. So the first question we ask a neighbor who calls is not "what is wrong with your water" but "which water are you on?" The answer changes everything that follows.
We can ask it with some authority because we are neighbors. Absolute Water Solutions is based on Bertram Lane, on the Travis County side of SH 71, and has been in business since 2003. Here is how the community sorts out, subdivision by subdivision.
The lake-water subdivisions
Along the shore, most homes drink treated Lake Travis water from a small plant. Windermere Oaks WSC, beside the Spicewood airport, serves about 460 people. Aqua Texas runs the Barton Creek Lakeside plant that opened in 2019, the company's first surface-water plant in the state, sized for 1,100 connections. Inverness Point and Ridge Harbor have their own intakes. Spicewood Beach and its neighbors Lakeside Beach, Eagle Bluff and Lake Oaks are on the regional system that LCRA built and Corix now runs, and Travis County MUD 13 buys Lake Travis water from the West Travis County PUA.
The Spicewood systems whose reports we have read disinfect with free chlorine, not the chloramine Austin Water uses. That matters for two reasons. Standard carbon handles free chlorine well, so a whole-house carbon system is a straightforward fix for the pool smell. But free chlorine reacting with lake organics forms trihalomethanes, and the small Spicewood plants run closer to the line than most: Inverness Point's 2021-23 TTHM average was 76 parts per billion against a federal limit of 80, Windermere Oaks was around 52, and Barton Creek Lakeside was in formal violation of the limit in the first two quarters of 2025. Aqua pointed to lake organics and to the July 2025 flood that damaged its intake and forced a blend of lake and well water. None of that is cause for panic. It is exactly what carbon at the point of entry and reverse osmosis at the kitchen tap are built to remove.
Spicewood Beach carries the community's water memory. In January 2012 its shallow riverbank wells fell with the lake and it became the first Texas town to run dry; LCRA trucked water in several loads a day for more than two years, until a lake intake and plant went online in June 2014. When LCRA's board voted on a new Water Management Plan in February 2026, Spicewood Beach residents were at the microphone again. Nobody out here takes a full tap for granted.
The well-field subdivisions
The other half of the utility map pumps from underground. Cypress Ranch WCID No. 1 serves roughly 1,500 people in West Cypress Hills from Trinity wells and has been posting Stage 3 restrictions with all sprinklers prohibited. The Coves WSC supplies The Coves and the Reserve at Lake Travis from a dozen or so Trinity wells and is adding a tandem Middle-and-Lower Trinity well because, in its own words, the ongoing drought reduced production. Aqua's Lakecliff system runs on Lower Trinity wells; Hazy Hills WSC, off Paleface Ranch Road, serves 135 people from its own.
These utilities disinfect, but none of them publishes a hardness figure, and the state water board describes Trinity water in this part of the aquifer as very hard. Their reports also show what a well field picks up on the way up: nitrate at Lakecliff (1.25 ppm, well under the 10 ppm limit but far above what the lake systems show), low-level uranium at Lakecliff and in Barton Creek Lakeside's wells, combined radium at Hazy Hills, and naturally high fluoride at Spicewood Estates on the Burnet side. All below legal limits; all reasons a Lakecliff or Coves kitchen tends to end up with a reverse osmosis faucet, and the house with a softener actually sized for the water.
The private-well side
Travis Settlement, Paleface Ranch, the Pace Bend Road corridor, Pedernales Canyon, Lick Creek and most of the acreage along SH 71 are on private wells and septic, often with a rainwater tank for irrigation. On the Travis side, wells reach the Trinity Group at 180 to 260 feet near Paleface and Pace Bend and the Lower Trinity at 370 to 755 feet; on the Burnet side the Trinity thins out and wells hit Ellenburger and Marble Falls limestone between 100 and 515 feet. No one publishes a hardness number for Spicewood, and we will not invent one. The one measured local value we know of is a single USGS Ellenburger well near Spicewood Beach, sampled in 2013: 459 mg/L of hardness, about 27 grains per gallon, with 482 mg/L of total dissolved solids. One well is not a map. That is why every recommendation we make starts with a test at your tap, not a county average.
Two other things define well ownership here. Water levels first: more than 2,000 wells have been drilled in southwestern Travis County since 2003, about 70 percent into the Lower Trinity, and monitor wells there are falling by up to three feet a year. That is why Paleface Ranch listings advertise 2,500-gallon storage tanks and booster pumps alongside the softener, and why a well treatment plan here has to account for stored water, blended rainwater and low flow rates rather than a steady 10 gallons a minute. Septic second: with drainfields cut into thin soil over rock, Texas allows a softener to discharge to a septic system only if it regenerates on demand, and RO reject deserves the same routing care. Bacteria and nitrate risk climb when a well sits close to a drainfield or was poorly cemented, which is why the Burnet County groundwater district now requires 50 feet of annular cement on new wells after finding the problem common. For the disinfection side of that equation we install Viqua UV systems, covered in depth on our water purification page.
Lakefront lots that pump straight from the lake
A meaningful number of Spicewood lots (at Pace Bend, Paleface Point, Ridge Harbor, Lakeside Beach, Eagle Bluff, Lake Oaks and along the Pedernales arm) pump raw water directly from Lake Travis under an LCRA domestic-use contract, which allows up to 10 acre-feet a year with a minimum of three-quarters of an acre-foot. That water is untreated. It carries sediment, turbidity after every rain, algae taste in summer, and whatever the zebra mussels that now fully infest Lake Travis leave on the intake screen. Making it safe for the house (sediment and turbidity, then taste, then disinfection) is the surface-water treatment this community was built around, and it is the part of the menu that separates a Spicewood installer from one driving in from town.
What being from here actually changes
Absolute Water Solutions has been at this for 23 years, with more than 1,000 systems behind us across the Hill Country and Austin, and every job is still done by our own crews. We hold TCEQ water treatment license WT001370 and are insured, and we work for homes and businesses alike, from the gated golf communities to the acreage tracts to the wine road along SH 71. On the map, being from here means Travis Settlement is about 14 minutes from the shop, the Pace Bend Park gate about 19, Krause Springs about the same over on the Burnet side, and Spicewood Beach about 24.
The community is changing under us, too. The ZIP has grown roughly six-fold since 2000, and Thomas Ranch, going up at SH 71 and Paleface Ranch Road, is the first Spicewood neighborhood built with a central treatment plant from day one. Its buyers will still ask the same question everyone else does, and we will still answer it the same way: test first, then size the system to what the test found.
We keep business hours, Monday through Friday, 8am to 5pm. Call (512) 587-8188 or request a free estimate, tell us which neighborhood you are in, and we will take it from there.
