Plumber in Alamo Heights, TX

What the water is like in Alamo Heights
Your water provider
City of Alamo Heights (not SAWS)
Alamo Heights runs its own water utility from its own wells. Sewer lines connect into the SAWS system, and SAWS reads the meters — but the water itself is the city's.
Source ↗Hardness
Not published
Alamo Heights does not publish a hardness figure — neither the 2025 nor the 2023/24 water quality report contains one. Its water is 100% Edwards Aquifer, which the Texas Water Development Board describes as "hard but fresh," but no one has published a number for this system. A test at your tap is the only honest way to size a softener here.

What we see here
Built out by 1950 and essentially unchanged since
Alamo Heights incorporated in 1922 and its population peaked around 1950 at roughly 8,000 — it was 7,357 at the 2020 census. The housing stock is 1910s–1940s with some 1950s infill; almost nothing has been added in seventy years.
The oldest plumbing we work on
A house built in the 1920s or 1930s has original drainage that is now roughly a century old — three to four decades past the 50–60 year service life documented for below-ground cast iron. Galvanized supply lines and clay tile laterals are the expected baseline here, not the exception, and many of these homes are pier-and-beam rather than slab.
Century-old trees over century-old laterals
Alamo Heights was platted specifically to preserve its old-growth trees, and those root systems have had a hundred years to find the joints in a clay sewer lateral. SAWS names tree roots as a blockage cause on its own system — the one Alamo Heights sewer connects into.
Renovation-driven work
A lot of what happens in 78209 is remodeling around plumbing that was never designed for a modern kitchen or a second bathroom. Repiping and drain rework during a renovation is nearly always cheaper than doing it after the finishes go in.

Common questions
Alamo Heights plumbing questions
Is Alamo Heights on SAWS water?
No. The City of Alamo Heights operates its own water utility from its own wells, and its 2025 water quality report states the Edwards Aquifer is its sole source. Sewer service connects into the SAWS system, and SAWS reads the meters, which is where the confusion usually comes from.
How hard is the water in Alamo Heights?
The city does not publish a hardness number — we checked both the 2025 and 2023/24 water quality reports and neither includes one. The supply is entirely Edwards Aquifer water, which the Texas Water Development Board characterises as hard, but we would rather test at your tap than quote you a figure nobody has published.
Should I replace the original cast iron in a 1930s house?
Not automatically — camera it first. Below-ground cast iron has a documented 50–60 year service life, so a 1930s line is decades past it, but the actual condition varies enormously section to section. An HD inspection tells you whether you are looking at a spot repair, a liner, or a full replacement, and what it will really cost.
