Why Your Drinking Water Choice Matters in Skippack
If you live in Skippack Township, you already know the area well. The old farmhouses along Skippack Pike. The newer developments off Heckler Road. The private wells that have been serving families here for generations, and the municipal water lines that reach parts of the township through North Penn Water Authority or Pennsylvania American Water.
What you may not know is what’s actually in your water by the time it reaches your tap. And that answer varies a lot depending on whether you’re on a well or on public water, and which part of the township you’re in.
When homeowners in Skippack — and in nearby communities like Evansburg, Collegeville, Worcester, Lansdale, and Harleysville — start thinking about a drinking water system, two options come up most often: reverse osmosis and ultrafiltration. Both produce cleaner water at the tap. But they work differently, target different things, and suit different households. Picking the wrong one doesn’t hurt you, but it might mean you’re spending money on a system that doesn’t actually solve your specific problem.
Here’s how to figure out which one belongs under your kitchen sink.
Not sure what’s in your Skippack water?
A free in-home water analysis takes the guesswork out of choosing the right system. We’ll test your water and walk you through the results in plain language.
How Reverse Osmosis Works
Reverse osmosis — most people just call it RO — pushes your water through a semi-permeable membrane with pores so small they block contaminants at the molecular level. It doesn’t just filter out particles. It removes dissolved substances that pass right through ordinary filters: lead, nitrates, arsenic, fluoride, and PFAS (the so-called “forever chemicals” that have shown up in groundwater across much of Montgomery County).
The tradeoff is that RO systems filter more slowly than ultrafiltration, and they do produce some wastewater in the process. For most households, that’s a minor inconvenience compared to the breadth of what they remove.
If you’d like a deeper look at the options, our guide on how to choose the perfect reverse osmosis system for your home covers the key decisions. And if you’ve heard concerns about RO removing beneficial minerals or wasting water, our article on debunking common myths about reverse osmosis addresses those directly.
How Ultrafiltration Works
Ultrafiltration (UF) also uses a membrane, but its pores are larger than an RO membrane. They’re still extremely fine — fine enough to block bacteria, viruses, cysts, and sediment — but dissolved minerals pass right through. That’s the key distinction.
You can learn more about both options on our ultrafiltration service page and our reverse osmosis service page.
Key Differences Between RO and UF Systems
Here’s a straightforward comparison to help you see where each system stands:
| Feature | Reverse Osmosis | Ultrafiltration |
|---|---|---|
| Removes dissolved solids (lead, nitrates, PFAS) | Yes | No |
| Removes bacteria and viruses | Yes | Yes |
| Removes sediment and particles | Yes | Yes |
| Retains beneficial minerals | No | Yes |
| Water waste | Some | Minimal |
| Flow rate | Slower (uses storage tank) | Faster |
| Maintenance complexity | Moderate (multi-stage filters) | Lower |
| Best for | Broad contaminant removal | Microbial and particulate concerns |
Neither system is objectively better. The right choice depends entirely on what’s actually in your water — which is why a water test is the right first step.
What’s in Skippack’s Water?
This is where it gets local — and where Skippack gets interesting.
Skippack Township sits in central Montgomery County, and its water picture is genuinely mixed. Parts of the township are served by public water through North Penn Water Authority or Pennsylvania American Water. Other neighborhoods — especially in the more rural stretches toward Worcester, Schwenksville, and Zieglerville — rely on private wells drawing from the underlying geology of the Perkiomen Creek watershed.
If You’re on a Private Well in Skippack
Well water in central Montgomery County tends to come up hard. The region’s geology — limestone and shale formations common throughout the Perkiomen and Skippack Creek drainages — naturally loads water with calcium and magnesium. If you’ve got scale buildup on your faucets, cloudy dishes, or that stripped feeling after a shower, hard water is almost certainly part of the picture.
Beyond hardness, private wells in this area can also carry iron, sediment, and bacteria — particularly in older wells or after significant rainfall. Some wells in the Skippack and Worcester Township corridor have also shown trace nitrates, especially in areas with agricultural history. For drinking water, any of these concerns could point you toward a point-of-use treatment system at the kitchen tap.
Our guide on well water risks for Pennsylvania homeowners and our article on annual well water checkups are both useful reading if you haven’t tested your well recently.
If You’re on Municipal Water in Skippack
Municipal water serving Skippack and surrounding communities like Collegeville, Trappe, and Lansdale goes through treatment before it gets to your home — but treatment at the plant doesn’t mean your water arrives at your tap problem-free.
PFAS is a real and documented concern in this part of Montgomery County. Nearby Lower Providence Township had PFAS levels that drew significant attention after Pennsylvania American Water’s acquisition of the Audubon system; the contamination was traced to local groundwater sources. While Skippack’s public water systems are separate, the broader regional PFAS picture is worth understanding. The EPA’s PFAS information page is a reliable starting point for understanding what these chemicals are and why they matter.
On top of PFAS, municipal water customers throughout Montgomery County deal with chlorine and chloramine used for disinfection. These do their job at the treatment plant, but by the time water travels through miles of distribution pipe and then through your home’s own plumbing, disinfection byproducts can accumulate. Older homes in Skippack, Lansdale, and Harleysville can also have aging interior plumbing that adds its own concerns — including lead from old solder joints or fixtures. You can read more about treating lead in your water on our site.
Also worth knowing: the real risk of unregulated contaminants in Montgomery County water is something we’ve covered in depth. Some contaminants simply aren’t required to be tested for — which is another reason a professional water analysis at your tap tells you more than any annual consumer confidence report from your utility.
What Standard Municipal Treatment Doesn’t Fully Address at Your Tap
Which System Fits Your Skippack Home?
A few honest questions can help you figure this out before you ever talk to a water treatment professional.
Choose Reverse Osmosis if…
Your water test shows elevated lead, nitrates, arsenic, or PFAS. You’re on municipal water and want protection beyond standard treatment. You have young children or immune-sensitive family members. You want the widest possible contaminant removal at your drinking tap.
Choose Ultrafiltration if…
Your main concern is bacteria, viruses, or particulate matter. You want to preserve naturally occurring minerals. You prefer minimal water waste and a simpler maintenance routine. Your water test shows no significant dissolved contaminant concerns.
For many Skippack homes — particularly those on private wells dealing with more than one issue — a layered approach makes the most sense. A whole-home system handles hardness or iron throughout the house, while a reverse osmosis or ultrafiltration system at the kitchen tap takes care of drinking water specifically. These systems work together. We cover this approach in our overview of drinking water systems and our article on water filtration, treatment, and purification — what’s the difference?

FAQs
What’s the main difference between reverse osmosis and ultrafiltration?
Reverse osmosis removes dissolved contaminants — lead, PFAS, nitrates, arsenic — by pushing water through an extremely fine membrane. Ultrafiltration uses a membrane with slightly larger pores that blocks bacteria, viruses, and sediment but lets dissolved minerals pass through. RO offers broader contaminant removal. UF is better suited for microbial and particulate concerns when you also want to keep naturally occurring minerals in your water.
Does reverse osmosis remove PFAS from drinking water?
Yes. Reverse osmosis is one of the most effective point-of-use methods for reducing PFAS in drinking water. Given the documented PFAS concerns in parts of Montgomery County — including issues that surfaced in nearby Lower Providence Township — this makes RO a particularly relevant option for many Skippack-area homeowners who want an extra layer of protection at the tap. You can read more about understanding PFAS and reducing your exposure on our site.
Does ultrafiltration remove bacteria and viruses?
Yes. UF membranes are fine enough to block bacteria, viruses, and cysts. For Skippack homeowners on private wells who are primarily concerned about microbial safety or sediment — and whose water tests don’t show elevated dissolved chemical contaminants — ultrafiltration is a strong and lower-maintenance option.
Will a reverse osmosis system remove beneficial minerals from my water?
RO membranes do remove most dissolved minerals, including calcium and magnesium. Some homeowners add a remineralization stage to their system to restore a portion of those minerals. If keeping minerals in your drinking water is a priority, ultrafiltration preserves them naturally. Either way, this decision is much easier to make once you know what your water actually contains.
My Skippack home is on a private well. Which system should I consider?
It depends on what’s in your well. Well water in central Montgomery County often carries hardness minerals, iron, and sediment. It can also carry bacteria or nitrates, particularly in older wells or areas with agricultural land nearby. The only way to know for sure is a professional water test. From there, the right system — RO, UF, or a combination approach — becomes clear. Schedule a free in-home water analysis and we’ll do the legwork for you.
Can I use both a whole-home treatment system and a point-of-use drinking water system?
Yes, and many Montgomery County homeowners do exactly that. A whole-home water softener or iron filter addresses hardness or iron throughout the house. A reverse osmosis or ultrafiltration system at the kitchen tap handles drinking and cooking water specifically. These systems complement each other — they’re not in competition. Our team can help you figure out whether one or both makes sense for your situation.
How often do these systems need maintenance?
RO systems typically require filter changes every six to twelve months, with the RO membrane lasting two to five years depending on your water quality and usage. UF systems have a simpler maintenance schedule with less frequent filter replacement. A local water treatment professional can set you up with a maintenance plan that fits your specific system and your Skippack-area water conditions.
