Pool Acid Washing in New Berlin, Texas
New Braunfels Quality Pool Resurfacing offers pool acid washing in New Berlin, Texas, the small city on Farm Road 2538 in southwestern Guadalupe County. An acid wash strips a thin layer from a drained plaster, quartz or pebble finish, taking stains and mineral scale with it. In New Berlin, the refill afterward runs on a rural water district's schedule.
Free estimates are a phone call or a form away, any hour. Before a date is held, we'll go over the stains, whether your finish can take a wash, and which of the two water districts serves your address.

Two water districts and their pool-filling hours
The City of New Berlin doesn't run a water system. For water problems, its questions-and-answers page sends residents to one of two districts: Green Valley Special Utility District or East Central Special Utility District. The state's map of water service areas puts the city's center inside Green Valley's area. We couldn't confirm which addresses East Central serves, so check your water bill.
Green Valley Special Utility District
Green Valley ties its stages to the Edwards Aquifer and to Canyon Reservoir:
- year-round rules while the aquifer stays above 660 feet at the district's monitored well;
- Stage 1 once the 10-day average falls to 660 feet;
- Stage 2 when the Guadalupe-Blanco River Authority and the Canyon Regional Water Authority announce Stage 2 conditions for Canyon Reservoir users;
- Stage 3 at 640 feet.
From Stage 2, a pool may take water only on designated watering days, in two windows: midnight to 10 a.m. and 8 p.m. to midnight. That covers filling, refilling and topping up, and Stage 3 keeps the same limit. On October 6, 2026, the district's page had a heading for the current restriction level, but its text named no stage.
East Central Special Utility District
East Central's Stage 3 flyer sets the same windows for pools: filling only on designated watering days, midnight to 10 a.m. and 8 p.m. to midnight, with the days set by address. Nothing we read from the district that day stated its current stage. Ask whichever district serves you before the pool is emptied.
Why the refill sets the schedule
Neither district lists acid washing in its rules; what they limit is the refill. That matters because an acid-washed pool stays empty until it's filled again. The National Plasterers Council warns that every drain carries some risk to the finish. If a warranty still covers the finish, the council suggests checking with the builder or plasterer before repairs.

(830) 302-4112Stains, scale and what a wash can reach
The plastering council traces faded or blotchy color to three causes:
- calcium salts working out of the cement and masking the pigment;
- scale: minerals or metals that drop out of the water and cling to the surface;
- cement compounds dissolving, which takes the pigment with them.
A wash works on what sits on top. Pigment leached out by water that stayed out of balance for a long time is gone for good, the council says.
Hard water from the tap
Green Valley's own 2025 report gives no hardness figure, but state samples of the district's treated water came back at 286 to 294 mg/L in January 2025. East Central's 2025 report gives no figure either. Water that hard can feed the second cause on that list.
When the wash is part of a resurfacing
A wash also comes up as prep. On 2026 national figures, draining, an acid wash of the old surface and chipping away plaster that has lifted off the shell can add $500 to $1,500 to a resurfacing. Treat that as an average; the price for your own pool comes with a free estimate.

(830) 302-4112The city's building permit ordinance
New Berlin's Building Permit Ordinance, No. 2021-002, says anyone seeking to build, enlarge, alter, repair or move a building or structure must apply to the city for a permit first. Among its stated aims is keeping the city's rural setting. The city enforces the International Residential Code for homes, and a site inside a subdivision needs written approval from its owners' association.
The permit form, with fees revised February 16, 2026, lists a $50.00 residential permit fee and a floodplain check by the city's Floodplain Administrator. The ordinance doesn't mention pools, and we found no city rule on pools, pool barriers or draining. Whether an acid wash counts as a repair isn't spelled out, so put the question to City Hall.
A German settlement on Farm Road 2538
Many of New Berlin's early settlers were German immigrants who arrived in the 1870s. Ed Tewes built the first store, and a post office ran from 1878 to 1906. By the mid-1880s the town had two steam gristmills and cotton gins, a general store and seventy residents. The city's own history page, contributed by the New Berlin Historical Society, credits Tewes with helping found the town in 1868.
The same page names Christ Lutheran Church at Elm Creek, founded February 14, 1886, and family cemeteries such as Schultze. It also calls Brietzke Station, the town's café, an institution in New Berlin. The town incorporated in 1980, when 253 residents were reported. The 2020 Census counted 656 people and 280 homes, and by the Census Bureau's July 1, 2025 estimate the city had 718 residents.
Beyond an acid wash
A wash can't fix every surface. Fiberglass, vinyl and painted pools aren't candidates for one, a national pool retailer's guide says. Etching can't be reversed either, a plaster maker notes, so a finish that has turned rough usually points to a new surface rather than another wash. Calcium on the waterline tile is often a separate job, cleaned with methods the tile maker allows.
East Central, one of New Berlin's two water districts, also delivers well water to La Vernia, over the Wilson County line. There, New Braunfels Quality Pool Resurfacing handles fiberglass pool resurfacing in La Vernia, the kind of pool an acid wash has to leave alone.

(830) 302-4112Planning an acid wash around the refill
Each step is general practice: finish makers publish the procedures, and the districts set the fill hours.
Free acid wash estimate
Phone or use the form at any hour and describe the stains: their color, where they sit and when they appeared.
Find your district and its stage
Green Valley or East Central: the bill says which. Ask the district's current stage before the pool is drained.
Check the finish
A plaster, quartz or pebble finish gets looked over for etching, hollow spots and loose plaster before any acid touches it.
Drain, wash and neutralize
The wash follows the finish maker's procedure, and the spent acid is neutralized before it's disposed of.
Refill in the permitted hours
The pool is filled again inside the district's watering days and hours, and then the water is balanced.

(830) 302-4112A question New Berlin pool owners ask
Is it necessary to acid wash a pool?
Not always. In the plastering council's definition, a wash dissolves material at the surface of a cement finish. That removes efflorescence (salts from the cement that dry white on the surface), dirt or stains. It can't restore pigment that out-of-balance water has already leached away. And if the water that left the scale stays as it was, a pool chemical maker warns, the scale tends to come back after the wash.
