Carnegie Water
Filtration
Andrew Carnegie put his name on this borough and built its library. Steel mills and coal mines built everything else — including the plumbing that still carries your water today.
PA American Water delivers treated water to your property line. What happens between the curb and your faucet is the part we fix.
The Steel Borough
By 1916, Carnegie had three railroad lines and 14 metal industries employing 6,270 people. Superior Steel, Union Electric Steel, and the coal mines that preceded them shaped every block — and every pipe — in this borough.

How Carnegie’s Water Reaches You
PA American Water
Pennsylvania American Water Company treats and delivers water to Carnegie — one of the largest regulated utilities in the state.
▸
Borough Mains
Water travels through distribution pipes beneath Main Street, Chartiers Creek crossings, and residential neighborhoods built between 1880 and 1950.
▸
Your Steel-Era Home
Water enters plumbing installed decades before the 1986 lead-free law — lead solder, galvanized pipe, brass fixtures. Clean water absorbs whatever your pipes release.
▸
Our Solution
Custom-engineered treatment matched to your water chemistry — accounting for PA American’s source water and your specific plumbing situation.
From Chartiers & Mansfield to Carnegie
In 1768, John and James Bell established the first permanent dwellings along Chartiers Creek. By the 1850s, coal mines were operating. Chartiers Borough and Mansfield Borough both incorporated in 1872 as related but separate communities — linked by two wooden covered bridges across the creek. On February 20, 1894, residents voted 670 to 125 for consolidation, and Carnegie was born — named for Andrew Carnegie, who donated the library that still stands on Beechwood Avenue.
Andrew Carnegie Free Library & Music Hall built — still active today with theater, lectures, and community programs.
Workers employed by Carnegie’s 14 metal industries by 1916 — most living within the borough’s 1.6 square miles.
The Plumbing Nobody Replaced
Coal mining gave way to steel. Steel gave way to quiet suburban life. But the plumbing installed during the boom — lead solder, galvanized pipe, brass fixtures — never gave way to anything. Most Carnegie homes still carry water through the same infrastructure built before the 1986 federal ban.
What Carnegie Homeowners Face
Steel-Era Plumbing
Carnegie’s consolidation in 1894 launched a building boom. Homes from the 1890s through the 1940s contain lead service lines, lead solder, galvanized pipe, and brass fixtures — all standard construction decades before the ban.
Chlorine Taste & Disinfection Byproducts
PA American Water uses chlorine to disinfect. When chlorine reacts with organic compounds, it creates trihalomethanes and other byproducts. Both the taste and the byproducts are treatable with whole-house carbon filtration.
Hard Water Scale
Dissolved calcium and magnesium cause white deposits on fixtures, spotted glassware, reduced water heater efficiency, and dry skin after showering. Common throughout western PA municipal water.
Lead Absorption Overnight
Water sits in vintage pipes while you sleep. By morning, it’s had hours to absorb whatever your solder joints, service line, and fixtures release. First-draw water carries the highest lead concentrations.
Aging Distribution Infrastructure
Main breaks, hydrant flushing, and pressure changes in the distribution system can introduce sediment and particulates. Carnegie’s dense, century-old pipe network makes this a recurring reality.
Why Carnegie Families Choose Cesare’s
PA American Water Chemistry
We design systems specifically for the treatment profile PA American delivers to Carnegie — not a generic solution. Different source water means different filtration needs.
Built for Pre-1986 Plumbing
Carnegie homes from the coal and steel era have plumbing from the same period. We account for what treated municipal water does after entering century-old infrastructure.
Test Before We Recommend
We analyze your water at your Carnegie home before suggesting equipment. Your system is designed around actual lab results — not a sales pitch.

Carnegie Water Questions — Answered
Who provides water to Carnegie?
Pennsylvania American Water Company — one of the largest regulated water utilities in the state. They treat and deliver water meeting or exceeding all federal and state standards. Call them at 1-800-565-7292 for billing; call us at 724-708-8816 for filtration.
Why does my water taste like chlorine?
PA American Water uses chlorine disinfection. The taste varies by season and your distance from treatment facilities. Whole-house Custom-Designed filtration eliminates chlorine taste and odor at every tap in your home.
Is Carnegie water hard?
Western PA municipal water typically contains dissolved calcium and magnesium. Symptoms include white scale, spotty dishes, and dry skin. A custom water softener eliminates hardness throughout your home.
Should I worry about lead?
Carnegie homes from the 1890s through 1940s were built with lead solder, galvanized pipe, and brass fixtures. PA American delivers clean water — but your plumbing can add lead. Testing confirms your specific exposure.
Does coal mining history affect the water?
Many Carnegie neighborhoods were once mined for coal. Your municipal water comes from PA American, not groundwater, so mining doesn’t directly affect it. But mining-era homes have the same vintage plumbing concerns as any pre-1986 construction.
How much does filtration cost?
Costs depend on your water chemistry and plumbing situation. We test first, then engineer a system for your actual conditions. Call 724-708-8816 for a consultation — no obligation.
Do you offer reverse osmosis?
Yes. High-flow RO with optional UV that helps inactivate microorganisms. Finishing options include pH Boost or Mineral Add-Back. Customers say it tastes better than bottled.
What school district is Carnegie in?
Carlynton School District — with an elementary school within the borough.
What’s your process?
Water chemistry analysis → Custom system design → Professional installation → Ongoing support with up to 10-year warranty (terms apply). Designed for PA American’s treatment plus your specific plumbing.
Do you serve all of Carnegie?
Every neighborhood in all 1.6 square miles — Rosslyn Heights, Cubbage Hill, Irishtown, Forsythe Hill, Library Hill, Old Mansfield, and the Chartiers Creek corridor. Call 724-708-8816.
