Water treatment in Briarcliff, TX is lake-supply work, on a subdivision that was platted long before anyone worried about it. The street signs give the era away. Sleat, Daviot, Oban, Kintail, Morar, Plockton, Fife, Bute, Elgin, Paisley, Scone: a Scottish gazetteer laid over a limestone peninsula on the south shore of Lake Travis, platted in the 1960s as a resort of summer cabins, country-club lots and water sports, with a chain of small ponds the property owners association still calls the lochs. The Briarcliff Yacht and Golf Club opened in 1968. The water plant went in the following year, 1969, and it still serves every home inside the Village of Briarcliff, which makes the plant older than more than nine in ten of the houses drinking from it.
That is the right way to read this village's water: by date. Absolute Water Solutions is based on Bertram Lane in Spicewood, in the same 78669 ZIP, about five road miles and a dozen minutes away by Bee Creek Road and Daviot Drive. Briarcliff is our next-door market. Here is its timeline, and what each chapter left behind in the plumbing.
1969: the plant that came with the resort
The original plant drew Lake Travis water from Cat Hollow Cove (the same cove that holds the Briarcliff Marina at lake mile marker 26), and a 1967 standpipe near the golf course is still in the system, refurbished after a newer one went up. The resort itself did not last. The club went bankrupt, and in 1979 Willie Nelson bought it for $250,000, turned the clubhouse into the Pedernales Recording Studio and kept the nine holes going as Pedernales Country Club. The houses of that first chapter did last: roughly 286 of Briarcliff's 1,165 homes were built before 1990, 82 of them before 1970, and they carry the plumbing of their decade. Original galvanized or copper lines. Water heaters that have spent thirty or forty years collecting scale from unsoftened lake water. Softeners retrofitted without a proper loop. Conventional septic tanks installed before anyone asked where a softener's brine goes.
1984 to 2001: the Village buys the plant, then outgrows it
The Village of Briarcliff took over the system in 1984, and by the late 1990s growth was outrunning it. The Village's own plant history credits that spurt with the decisions that define the water today: hollow-fiber membrane microfiltration, expansions in 1994-95 and 2001, a second standpipe (the two now hold 500,000 gallons), 160,000 gallons of clearwell at the plant and 26 miles of distribution main. Two booster pump stations, one in the North Ronay area and one near the golf course, went in to cure what the history calls chronically low pressure on the higher streets.
Two things follow for a homeowner. First, membranes strip out particles and microbes (the 2025 report shows turbidity at 0.02 NTU) but not dissolved calcium and magnesium. The Village report does not print a hardness figure, and we will not invent one. The closest honest reference is Lakeway MUD's 2025 report on the same unsoftened lake water, 184 mg/L, roughly 10.8 grains per gallon; treat that as a lake reading, not a Briarcliff reading, until a test at your tap settles it. Second, on North Ronay, South Ronay and the golf-course streets the water arrives through boosters and check valves, so a softener or RO there gets a pressure regulator, correct backflow protection and, on a street with a low-pressure history, a tank-style RO rather than a tankless one.
2000 to today: six in ten homes, one 2025 report
Briarcliff counted 895 people in 2000, 1,438 in 2010 and 2,062 in 2020. Of its 1,165 housing units, 378 went up between 2000 and 2009, 275 in the 2010s and 40 since 2020: 60 percent of the village, built as infill on the Scottish-named plat, on the hilltop East and West Summit Drive section near Bee Creek Road, and along the Cat Hollow waterfront. Median household income is about $141,000, nearly nine in ten homes are owner-occupied, and the median home is worth roughly $551,000. These are copper-and-PEX houses with pre-plumbed loops, tankless heaters, aerobic septic units and, often, a builder-grade softener nearing the end of its life.
What all of them drink is spelled out in the Village's 2025 Consumer Confidence Report. Disinfection is chloramine, averaging 2.02 mg/L with a range of 0.33 to 3.8, which needs catalytic carbon and real contact time rather than a standard carbon block. Trihalomethanes ran a highest annual average of 55 parts per billion, with a single sample of 80.3 ppb at 910 Daviot Drive against an 80 ppb limit, and haloacetic acids reached 37.5 ppb at 1705 Judy Lynn Drive: both at the far ends of the mains, both within the rules, both a fair reason for carbon at the point of entry and reverse osmosis at the kitchen tap. Copper measured 0.552 ppm at the 90th percentile, with a top result of 0.876 against a 1.3 action level, which points at house plumbing and the 7 percent of homes that sit empty between weekends. The report recorded no violations, and that is the honest baseline: Briarcliff's water is safe by its own numbers, and what a home system does is finish the job (taste, scale, byproducts, and a UV stage for households that want disinfection that does not depend on the plant).
One distinction is worth being precise about. The Village plant is itself a membrane surface-water plant, so the residential job inside the village is polishing treated lake water, not treating raw lake water. The exception is a dock pump or an outlying lot with its own intake, where zebra mussels (established in Lake Travis since 2017), summer algae and post-flood turbidity all land on the homeowner. That is the surface water treatment side of our work, and it is designed lot by lot.
What never changed: no sewer, one property owners association
Through every chapter, two things held. The Village has never had a municipal sewer (its utilities page lists water and garbage, nothing else), so every home is on an on-site septic system, and every softener or RO drain ends up in one. State law permits softener brine in a septic system on one condition: the unit must regenerate on demand, from metered use, not on a clock, and on an aerobic unit the backwash is routed around the treatment tank into the pump tank. We build to that rule, and it happens to be the efficient design anyway. The Village is under a Stage One mandatory schedule of two outdoor watering days a week, its 2025 audit logged about 7.6 million gallons of system water loss, and a demand-initiated softener paired with a low-reject RO is how a treatment system stays on the right side of a utility counting gallons.
The other constant is the Briarcliff Property Owners Association, whose deed restrictions (amended in 1984, current version effective 2000) and Architectural Control Committee govern exterior work. We keep most systems in the garage on the loop; when a pad has to go outside, you will hear from us up front if it needs ACC sign-off.
Off the mains: Bee Creek, Pace Bend and Thurman Bend roads
Past the village sign the addresses read Spicewood and the water comes from Trinity wells. That acreage sits inside the Southwestern Travis County Groundwater Conservation District, created in 2017 and confirmed by voters in 2019, which requires every existing well to be registered, sets setbacks between wells and septic systems, and stepped down from a severe-drought stage to a D-1 moderate stage on July 30, 2026 while warning that groundwater levels remain near historic lows. The regional atlas is blunter: Middle Trinity wells in southwestern Travis County have gone dry as levels fell over 40 years, and more than 70 percent of the 2,000-plus wells drilled since 2003 go to the Lower Trinity. No one has published well chemistry for the Briarcliff fringe, so we do not guess at it. Trinity water in this belt tends to run hard, with sulfur and iron possible in the Glen Rose and Hensell zones, so a lab panel for bacteria, nitrate, hardness and metals comes first, and the well treatment train, sediment, softening, iron or sulfur removal where the test finds it, Viqua UV, is sized from the result. Rainwater systems, which the district actively promotes, get sediment, carbon and UV before the water reaches a tap.
