One of Allegheny County’s Original Seven
Why Water Treatment in Plum Requires 29 Square Miles of Knowledge
Plum Borough is Pennsylvania’s second-largest borough by area — 29 square miles of Allegheny River valley, creek hollows, hilltops, and everything in between. Founded in 1788 as one of Allegheny County’s original seven townships, Plum once stretched from Pittsburgh to the Westmoreland County border. Today it is home to more than 27,000 residents, the world-famous Oakmont Country Club (host of a record 10 U.S. Opens), and the 1,096-acre Boyce Park.
That enormous footprint means enormous variety in water infrastructure. The Plum Borough Municipal Authority purchases water from the Municipal Authority of Westmoreland County and distributes it through six storage tanks and miles of waterlines. The Oakmont Water Authority also serves portions of the borough. Each neighborhood — from the historic coal patch communities of Renton, Barking, and Logans Ferry to the upscale developments along Holiday Park — has different pipe ages, materials, and water quality at the tap.
Where Creek Meets Suburb
Plum Creek, the borough’s namesake, rises in the southern hills and flows north through the heart of the community before entering the Allegheny River between Oakmont and Verona. Pucketa Creek forms the eastern boundary with Lower Burrell. These waterways, combined with the Pennsylvania Turnpike cutting through the borough’s center, define neighborhoods that evolved in very different eras — and left behind very different plumbing.

Water Challenges Across Plum Borough
A 29-square-mile borough with multiple water providers means water quality varies block to block. These are the most common issues.
Hard Water Scale
MAWC-sourced water carries calcium and magnesium through the Youghiogheny and Beaver Run systems. White deposits appear on faucets, showerheads, and inside water heaters. Hard water shortens appliance life across every Plum neighborhood.
Iron Staining
Orange-brown stains on sinks and laundry. Distribution line age varies dramatically across Plum — from 1950s-era pipes in Renton to 2000s construction in Holiday Park. Older lines contribute iron and sediment between the source and your tap.
Chlorine Taste & Odor
MAWC treats surface water with chloramine (a chlorine-ammonia compound) that is more persistent than free chlorine. Seasonal switching between disinfection methods changes the taste at your tap — especially noticeable in spring and summer.
Lead Concern
Older homes in Plum’s coal-era neighborhoods may have lead solder joints, lead service lines, or galvanized pipes that leach metals. The only way to know is testing at your tap — not the treatment plant.
Low pH in Well Areas
Some properties in Plum’s outer hills still rely on private wells tapping into coal-era geology. These wells often test acidic — corroding copper pipes and creating blue-green stains on fixtures.
Total Dissolved Solids
MAWC water originates from multiple reservoirs and river sources. Dissolved minerals accumulate through miles of transmission — affecting taste, ice clarity, and cooking quality throughout Plum Borough.
Where Plum’s Water Comes From
Plum Borough Municipal Authority
PBMA purchases water from the Municipal Authority of Westmoreland County (MAWC), which draws from Beaver Run Reservoir and the Youghiogheny River. PBMA operates six storage tanks and the High School pump station on Leechburg Road, serving approximately 9,800 customers. The Oakmont Water Authority also serves portions of the borough near the Allegheny River.
Private Wells
Some properties in Plum’s outer areas — particularly in the southern hills near Boyce Park and along Pucketa Creek — still rely on private wells. These tap into sandstone and shale aquifers influenced by coal-mining geology, producing water that can test high for iron, manganese, sulfur, and low pH.
How We Solve Plum Water Problems
Call or Message
Reach us at (724) 708-8816 or fill out the form below. We schedule a visit to your Plum home — often within days. You talk directly with the owner.
On-Site Water Testing
We test at your tap for hardness, iron, pH, TDS, chlorine, plus manganese and sulfur as applicable. Results happen in your home — not in a lab across town.
Custom System Design
We engineer a system with Custom-Designed media matched to your exact water chemistry, pipe material, household size, and water pressure. A Holiday Park ranch from 1970 needs a different system than a new build on Oakmont Heights.
Install & Verify
Professional installation by the owner. We confirm clean water at every tap and back it with up to a 10-year warranty (terms apply). 24/7 emergency service from day one.
From Coal Patches to Cul-de-Sacs
Plum’s early development centered on coal mines and oil and gas fields. The mining towns of Barking, Renton, Unity, and Logans Ferry still survive as neighborhoods — complete with 1920s-era galvanized pipes beneath century-old miners’ housing. Meanwhile, developments built in the 1960s-80s along Holiday Park and Saltsburg Road used copper with lead-soldered joints. New construction from the 2000s forward uses PEX and CPVC.
Your water treatment system needs to account for what your pipes contribute. A home in Renton from 1925 puts fundamentally different things into your water than a 2015 build near Oakmont Country Club — even though both receive the same MAWC supply.

Very professional and knowledgeable. Lance took the time to explain everything and did not try to oversell. Our water is so much better now. Would recommend to anyone!
Lance did an amazing job. Very thorough testing and explained everything about our water situation. The system he recommended has made a night-and-day difference. Outstanding service!
Plum Borough Water Treatment Questions
Where does Plum Borough’s water come from?
The Plum Borough Municipal Authority purchases treated water from the Municipal Authority of Westmoreland County (MAWC), which draws from Beaver Run Reservoir and the Youghiogheny River. PBMA operates six storage tanks and distributes to approximately 9,800 customers. The Oakmont Water Authority also serves some areas near the Allegheny River.
Why does my water taste like chlorine?
MAWC uses chloramine (a chlorine-ammonia compound) as a disinfectant. It is more persistent than free chlorine and can produce a noticeable chemical taste, especially during seasonal treatment changes. A whole-house system with Custom-Designed media removes chloramine before water reaches any tap.
Do older Plum homes have lead pipes?
Some homes in Plum’s coal-era neighborhoods and mid-century developments may have lead solder, lead service lines, or galvanized pipes. The only way to know what your pipes contribute to your water is testing at your tap. We test on-site and recommend treatment based on your actual results.
What does your on-site water test include?
We test at your tap for hardness, iron, pH, TDS, chlorine, plus manganese and sulfur as applicable. We also evaluate flow rate and water pressure. Results happen in your home — no sending samples to a lab.
How are your systems different from store-bought filters?
We custom-engineer every system around your test results. We select Custom-Designed media for your specific contaminant levels, pipe material, household size, and water pressure. A 1920s Renton home needs a fundamentally different approach than a 2015 build in Holiday Park.
How much does a water treatment system cost?
Pricing depends on water chemistry, contaminant levels, home size, and system complexity. We provide a clear recommendation after testing. Financing and system leasing available (terms apply).
Do you offer financing or leasing?
Yes. Financing and system leasing available (terms apply). Better water does not have to wait.
Can you repair my existing water system?
Absolutely. We service and repair softeners, filters, UV systems, and other equipment regardless of who installed it. Many Plum homeowners call us after their original company stopped returning calls.
What warranty and support do you provide?
Up to 10-year warranty (terms apply), plus 24/7 emergency service. We are local — not a call center in another state.
How long does installation take?
Most whole-house installations complete in a few hours. We confirm clean water at every tap and walk you through every component before we leave.
