Brownsville plumbing questions
Does Brownsville use desalinated water?
Yes, a desalination plant treats brackish groundwater for about a quarter of the city's use.
Why did Brownsville build a desalination plant?
Drought got so severe that the Rio Grande dried up before reaching the Gulf in 2000.
Are slab leaks common in Brownsville?
Clay soils and slab foundations make them a frequent repair.
Do Brownsville homes need a water softener?
Rio Grande water treated in the Valley is moderately hard to hard, so many homes see scale on fixtures and in water heaters. A softener protects tankless heaters and reduces spotting, but check the brackish-groundwater desalination blend in your area and your heater's warranty limits before sizing one.
