Common Water Problems in O’Hara Township
Both Fox Chapel Authority and Aspinwall/PWSA treat your water at the plant — but what happens between the plant and your tap matters just as much.
Hard Water & Scale
Allegheny River source water carries dissolved calcium and magnesium. O’Hara homes show white scale on fixtures, spotty dishes, reduced water heater efficiency, and dry skin throughout.
Chlorine & Chemical Taste
Both water providers use chlorine-based disinfection. The chemical taste is noticeable at the tap, especially during warmer months when treatment levels increase. Filtration removes it at every faucet.
Aging Infrastructure
The average O’Hara home was built around 1958. Mid-century plumbing — galvanized steel, copper with lead solder, and original service connections — releases rust, sediment, and corrosion particles into tap water.
Lead from Mid-Century Plumbing
Pre-1986 homes commonly used lead solder, lead service lines, and brass fixtures. Water leaves the plant lead-free but can pick up lead from your home’s plumbing. Testing confirms your specific risk.
PFAS & Emerging Contaminants
PFAS compounds have been detected in Allegheny River source water. RIDC Park’s industrial history adds local context. Home-level filtration provides additional protection beyond plant treatment.
Flood Sediment & Turbidity
O’Hara’s Allegheny River frontage and creek valleys — Squaw Run, Powers Run — make it vulnerable to flooding events that introduce sediment and turbidity spikes into the water supply.
O’Hara Township’s Water Providers
Two authorities serve O’Hara’s five non-contiguous sections. Both draw from the Allegheny River.
Fox Chapel Authority
Serves all of Fox Chapel Borough and approximately two-thirds of O’Hara Township, primarily the east side and portions of the west. Purchases water from PWSA’s Allegheny River treatment plant on Freeport Road. Also serves parts of Harmar and Indiana Townships.
Aspinwall / PWSA Connection
The remaining portions of O’Hara Township receive water through connections to the Aspinwall Borough system, which is supplied by both PWSA and Fox Chapel Authority. Same Allegheny River source, different distribution path and infrastructure age.
Mid-Century Housing Stock
O’Hara’s post-war building boom followed Route 28 expansion and RIDC Park (1964). Average home built 1958 — meaning galvanized steel, copper with lead solder, and original service lines are standard throughout the township’s 3,381 housing units.

O’Hara Township Water Filtration — Frequently Asked Questions
O’Hara Township is served by two main providers. Fox Chapel Authority supplies approximately two-thirds of the township, primarily the east side and portions of the west. Remaining areas receive water through connections to the Aspinwall/PWSA system. Both source water from the Allegheny River.
Both Fox Chapel Authority and PWSA use chlorine-based disinfection. The chemical taste is noticeable at the tap, especially during warmer months. A whole-house Custom-Designed filtration system removes chlorine at every faucet in your home.
Allegheny River source water carries dissolved minerals that cause moderate hard water in many O’Hara homes. White scale on fixtures, spotty dishes, reduced water heater efficiency, and dry skin are common signs. A custom-engineered water softener eliminates hardness at every fixture.
The average O’Hara Township home was built around 1958, during an era when lead solder, lead service lines, and brass fixtures were standard. Water leaves the treatment plant lead-free but can absorb lead from your home’s plumbing. Testing confirms whether lead is present at your tap.
PFAS compounds are an emerging concern in Allegheny River source water. Homeowners wanting additional protection can install Custom-Designed filtration or reverse osmosis systems engineered to target PFAS compounds.
Costs depend on your water chemistry. We test your water first, then engineer a system matched to your exact conditions — no generic packages. 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. Customers often tell us their water tastes better than bottled.
O’Hara’s five non-contiguous sections mean water reaches homes through different distribution paths — Fox Chapel Authority on the east, Aspinwall/PWSA connections on parts of the west. Each path has its own infrastructure age. Testing your specific home’s water is the only way to know what’s coming through your pipes.
We start with a detailed water chemistry analysis at your O’Hara Township home. Then we custom-engineer a treatment system matched to your specific results. Professional installation follows, backed by ongoing support and an up to 10-year warranty (terms apply).
Yes. We serve all five non-contiguous sections — all 7.3 square miles from the Route 28 corridor to Pleasant Valley, Squaw Run to the Allegheny River. Call 724-708-8816 to schedule your consultation.
