From a farm community to a small city
Union Valley was settled in the 1880s as a school and church community for area farmers, the Handbook says. The railroads bypassed it, its population never passed fifty in the Handbook's counts, and twenty-five residents were reported in 1986 and 1990. Today it is an incorporated city in the Census Bureau's files, and the 2020 Census counted 142 homes there, up from 117 in 2010.
The Bureau's 2020–2024 survey sample is small here, so its shares are rough: 42.2% of homes were built in 2010 or later, 25.9% from 2000 to 2009 and 24.8% before 1990, with a median year built of 2007. Single-family detached houses make up 75.2% and mobile homes 22.4%, about 97.2% of occupied homes are lived in by their owners, and the median owner-occupied home is valued at $325,900.

(469) 653-0486Permits: ask the City of Union Valley and Hunt County
We found no website or published code for the City of Union Valley, and no building or pool permit rule for the city. That is not the same as finding that none applies. Before a pool is drained, ask the City of Union Valley and Hunt County what the job needs.
State law sets a baseline. Texas adopts the International Swimming Pool and Spa Code as it existed on May 1, 2019 as the municipal pool and spa code in the state, lets a city adopt a newer edition, and applies the code to all construction, alteration, remodeling, enlargement and repair of pools in a city that elects to regulate them. Whether Union Valley does wasn't found.
No local rule on where drained pool water may go turned up either. The Texas Commission on Environmental Quality counts pool drain water as alternative onsite water, and its reuse rules, which cover private homes, let an owner irrigate with it without TCEQ authorization. The owner is responsible for doing it properly: no reuse within five days after shock or acid treatment chemicals go in, no ponding or runoff across property lines or onto paved surfaces, and no physical connection between the reuse system and a sewer or septic system.

(469) 653-0486Cash SUD water and its drought stages
All of Union Valley lies in Cash Special Utility District's service area on the Texas Water Development Board's map. Cash SUD serves about 250 square miles in parts of Hunt, Rockwall, Rains and Hopkins counties, with 7,610 connections and an estimated 21,000 people, according to its plan adopted April 22, 2024. Its 2025 water report says the Union Valley area south of Interstate 30 gets treated water bought from the North Texas Municipal Water District, which draws from Lake Lavon, while Cash's own Lake Tawakoni plant serves its areas north of I-30.
The plan's pool rules are the one official rule we found that touches an acid wash, because the pool has to be emptied first. Stage 1 encourages all users to drain and refill pools less often. Stage 3 prohibits filling, draining or refilling existing pools, wading pools, Jacuzzis and hot tubs, except to maintain structural integrity, for proper operation and maintenance, or to alleviate a public safety risk; it still allows topping up for normal losses and stops permits for new pools. None of the Cash SUD pages we read named the stage in force, so ask the district before the pool is drained.

(469) 653-0486Crockett loam and groundwater under an empty pool
The USDA Natural Resources Conservation Service soil map puts Crockett loam under 35.9% of Union Valley, Wilson silt loam under 20.3%, the Lufkin-Rader complex under 17.5%, Axtell loam under 13.0% and frequently flooded Hopco silty clay loam under 9.2%. NRCS gives the main Crockett soil a maximum linear extensibility of 9 percent and up to 46 percent clay, and the soils it rates very limited for slab houses because they shrink and swell cover 85.6% of the city's mapped land; that rating is for houses, not pools.
River Pools, a fiberglass pool maker, explains why an empty pool needs care: groundwater around a pool pushes up against the shell, a full pool is heavy enough to resist it, and with too little water inside a shell can bulge, crack or even float, a principle it applies to all pool types. It adds that the soil decides how long water stays in the ground around a pool, with sandy soil the most permeable and clay the least.

Check the stage and the rules
Cash SUD's drought stage decides whether the pool can be drained now, and the City of Union Valley and Hunt County say what else the job needs.
Dilute the acid safely
The CDC's Model Aquatic Health Code, voluntary national guidance, adds concentrated chemicals to water, never water to the chemical, and never mixes two chemicals in the same dilution water; NIOSH lists eye and skin burns among hydrochloric acid's hazards.
Wash from the deep end up
SGM starts in the bowl and works up to the shallow end to avoid streaks, washes walls and steps last, and doesn't let the acid solution puddle in the bowl.
Neutralize and pump out
SGM and CL Industries neutralize the acid with soda ash or baking soda and rinse, and SGM pumps the runoff out only after it is diluted and neutralized.
Refill and test at once
The National Plasterers Council tests the water as soon as the pool is refilled and balances it to its start-up procedure, which can take 7 to 10 days.
