Dormont Water Treatment
Your borough’s name means “Mountain of Gold” — shouldn’t your water live up to it?
Dormont homes grew alongside Pittsburgh’s streetcar lines. The plumbing in most homes is 100 years old. We custom-engineer water treatment systems that solve what PA American Water can’t: the last 100 feet of century-old pipe between their main and your tap.

100 Years of Plumbing Between You and Clean Water
Pennsylvania American Water treats your water to federal standards. It leaves their plant clean. But then it travels through distribution mains and into homes built when Woodrow Wilson was president.
Dormont exploded as a streetcar suburb after the Liberty Tunnels opened in 1924. Nearly every home you see was built between 1909 and 1935 — with the plumbing technology of that era:
- Galvanized steel pipes that corrode from the inside, releasing rust and sediment
- Lead solder on copper joints standard before 1986 regulations
- Lead service lines connecting many homes to the water main
- Brass fixtures containing up to 8% lead by weight
- Original shut-off valves that haven’t been replaced in a century
PA American Water can’t fix your home’s plumbing. That’s where we come in.
Dormont incorporates — first South Hills municipality
Liberty Tunnels open — population explodes
Borough essentially built out — housing stock set
Lead-free plumbing regulations begin — 50+ years too late for Dormont
Your water still travels through that same plumbing
What Dormont Homeowners Notice
Chlorine Taste & Smell
PA American disinfects with chlorine. The taste concentrates as water sits in older pipes. You notice it in drinking water, coffee, ice cubes, and cooking.
White Scale Everywhere
Hard water minerals build up on faucets, showerheads, water heaters, and dishwashers. Appliances fail early. Glass stays spotted. Showers look dirty even when clean.
Rust-Colored Water
Galvanized pipes corrode from within. Water runs orange after sitting overnight or after pressure changes. Sediment collects in aerators and water heater tanks.
Lead Concerns
Lead leaves no taste, no color, no smell — but it’s likely present in pre-1986 plumbing. Testing is the only way to know. Treatment is the only way to remove it.
Pennsylvania American Water
PA American Water is the largest investor-owned water utility in Pennsylvania, serving Dormont and dozens of South Hills communities. They treat water to meet federal standards and conduct regular main flushing to maintain distribution quality.
But federal standards measure water at the treatment plant — not at your 1920s tap. PA American can’t control what happens inside your home’s plumbing. That’s the gap we fill.

Dormont Water Filtration — Frequently Asked Questions
Pennsylvania American Water provides municipal water service to all of Dormont Borough. PA American sources water from regional treatment facilities and distributes it through infrastructure dating to the streetcar era.
PA American Water uses chlorine-based disinfection to meet federal standards. The taste concentrates as water sits in older pipes and travels through century-old plumbing. A whole-house Custom-Designed filtration system removes chlorine at every faucet.
Many Dormont homes experience moderate hard water. White scale on fixtures, spotty dishes, and dry skin are common signs. A custom-engineered water softener eliminates hardness at every fixture in your streetcar-era home.
Dormont’s housing stock is almost entirely from the streetcar era (1909-1930s). Lead solder, lead service lines, and brass fixtures were standard. Water leaves the plant lead-free but absorbs lead traveling through your home’s plumbing. Testing confirms your risk.
Dormont is derived from the French “mont d’or” meaning “Mountain of Gold.” The name was chosen when the borough incorporated in 1909 as the first independent municipality in Pittsburgh’s South Hills.
Costs depend on your water chemistry and your home’s specific plumbing configuration. Dormont’s dense streetcar-era housing often requires custom approaches. We test first, then engineer a matched system. Call 724-708-8816 for a consultation.
Yes. We install high-flow reverse osmosis systems with optional UV disinfection that helps inactivate microorganisms. Finishing options include pH Boost or Mineral Add-Back. Dormont customers tell us their water tastes better than bottled.
Dormont grew 479% between 1910 and 1920. Nearly every home predates modern plumbing standards. Galvanized pipes, lead solder, brass fixtures, and original service lines from 100+ years ago all affect water quality between the main and your tap.
PFAS compounds are an emerging concern in Pennsylvania water sources. PA American Water has conducted voluntary PFAS sampling. Homeowners wanting protection can install Custom-Designed filtration or reverse osmosis systems engineered to target PFAS.
Yes. We serve every block of Dormont’s 0.76 square miles — from Potomac Avenue to West Liberty, from the Mt. Lebanon border to Brookline. Call 724-708-8816 to schedule.
