Water Treatment and Plumbing Services in Upper Macungie Township, PA
Upper Macungie Township is one of the fastest-growing communities in Pennsylvania — the fourth fastest-growing municipality of any category in the state between 2010 and 2020. Covering 26.3 square miles of central Lehigh County across ZIP codes 18031 (Breinigsville), 18051 (Fogelsville), and 18087 (Schnecksville area), the township is a blend of established Pennsylvania Dutch villages, modern residential developments, preserved farmland, and major industrial and commercial operations. The Parkland School District draws families from across the Lehigh Valley, and with a median household income among the highest in Pennsylvania, Upper Macungie homeowners invest seriously in their properties. The township is also home to one of the most well-known water quality endorsements in the region: the Samuel Adams Pennsylvania Brewery in Breinigsville chose this location specifically because of the exceptional limestone aquifer underlying the Fogelsville area — the same aquifer system that also supplies Clover Hill Vineyards and other local producers who depend on water quality for their product. Dierolf Plumbing and Water Treatment has served Lehigh County families since 2009, starting every service with a free professional water test before recommending any treatment solution.
Most of Upper Macungie Township’s developed neighborhoods are served by the Lehigh County Authority’s Central Lehigh Division — the same 14-well groundwater system that supplies much of central and western Lehigh County. LCA’s own Consumer Confidence Reports document hardness in the Central Lehigh Division at 12 to 18 grains per gallon, firmly in the very hard category. That limestone geology that made this aquifer attractive to a world-class brewery also means every household drawing from it is dealing with significant calcium and magnesium mineral content. At 12 to 18 GPG, hard water causes real, measurable damage to water heaters, dishwashers, washing machines, and pipes over time. The scale buildup that homeowners see on showerheads and fixtures is just the visible portion of what is happening inside appliances year after year. A properly sized water softener is the most effective long-term solution for Upper Macungie Township households on LCA water. EWG analysis of the Central Lehigh system also identifies disinfection byproducts and chromium (hexavalent) above EWG health guidelines. A reverse osmosis system at the drinking water tap removes these contaminants at the point that matters most: the water your family drinks and cooks with every day.
Upper Macungie Township is notably more rural than its neighbor to the east, and a meaningful portion of the township — particularly in the agricultural stretches around Fogelsville, Krocksville, the Schnecksville corridor, and the northern tier approaching Lowhill and Weisenberg townships — relies on private on-lot wells. The same limestone carbonate bedrock that produces very hard LCA groundwater also runs beneath private wells throughout the township, and the agricultural land use across Upper Macungie’s preserved farmland creates real risk for nitrate contamination and bacterial infiltration from surface runoff. Iron and manganese are consistently documented in Lehigh County well water, producing the orange staining on fixtures and metallic taste that many well owners accept as normal. Our iron filtration systems address this at the whole-house level. Pennsylvania DEP recommends annual testing for bacteria and nitrates for all private well owners, and our well systems services cover comprehensive testing, treatment design, and pump and pressure tank maintenance.
For private well owners in Upper Macungie Township who face bacterial contamination risk — particularly those near older septic systems or agricultural fields — a UV disinfection system provides chemical-free whole-house protection without altering the taste or chemistry of the water. The township’s own mandatory sewage system inspection program for on-lot systems reflects the density of well-and-septic properties that remain throughout the more rural sections of Upper Macungie. Whether your home is in one of the newer Breinigsville developments on LCA water or a long-established property in Fogelsville or Krocksville on a private well, the water quality challenges are real and specific. Our free water test is how we find out exactly what is in your water before we recommend anything. Neighboring communities including Lowhill Township, Weisenberg Township, and Lower Macungie share the same aquifer system and the same hardness profile, and Dierolf’s deep Lehigh County expertise applies to every Upper Macungie home we serve.

Upper Macungie Township Water Treatment and Plumbing Services
Upper Macungie Township is a community that invests in quality — in its schools, its preserved open spaces, and its homes. Water quality deserves the same attention. Whether a homeowner is on LCA’s Central Lehigh groundwater system dealing with 12 to 18 GPG hardness and documented disinfection byproducts, or on a private well in the more rural sections of the township where iron, bacteria, and nitrates require independent testing, the water picture here is specific and manageable with the right approach. Before Dierolf recommends anything, we find out exactly what each home is working with. Our free water test gives you precise numbers at your tap — hardness, iron, pH, bacteria, and byproduct levels — rather than a regional average. If the water is in good shape, we say so and walk away without selling you anything. That is how we have operated since 2009, and it is the foundation of every relationship we build in Lehigh County.
For Upper Macungie Township homeowners ready to act, the solutions are matched to what this community’s water actually delivers. A whole-house water softener addresses the 12 to 18 GPG hardness that shortens the life of your water heater and appliances while leaving scale on every fixture in the home. A reverse osmosis system under the kitchen sink removes disinfection byproducts, chromium, PFAS, and dissolved contaminants from the water your family drinks and cooks with every day. For well owners in the rural sections of the township, an iron filtration system clears staining and metallic taste at the whole-house level, and a UV disinfection system provides bacterial protection without chemicals. Our licensed technicians handle every installation neatly and completely, leaving your basement or utility room tidy and your system clearly labeled for easy maintenance. We have served Lehigh County families since 2009 and stand behind every system we install.

Frequently Asked Questions in Upper Macungie Township
Why is Upper Macungie Township water so hard, and what can I do about it?
The hardness in Upper Macungie Township water is a direct product of the limestone carbonate geology underlying the central Lehigh Valley. The same aquifer system that drew the Samuel Adams Pennsylvania Brewery to the Fogelsville area — prized for its mineral-rich groundwater — is what produces 12 to 18 grains per gallon of hardness in LCA Central Lehigh Division water throughout the township. Calcium and magnesium dissolved from that limestone bedrock are beneficial minerals, but at this concentration they cause scale buildup inside your water heater, dishwasher, and appliances, reducing their efficiency and shortening their lifespan. Our article on 7 ways a water softener protects your water heater walks through the financial cost of untreated very hard water. A whole-house water softener removes hardness minerals before they reach any fixture or appliance. Our free water test confirms your exact hardness reading so we can size the system correctly for your household.
I have a private well in Fogelsville or the northern part of Upper Macungie Township. What should I be testing for?
Pennsylvania DEP recommends annual testing for total coliform bacteria and nitrates for all private well owners. For Upper Macungie Township properties in the Fogelsville, Krocksville, Schnecksville, and northern rural sections, we also recommend testing for iron, manganese, pH, hardness, and total dissolved solids. Homes near active farmland or older septic systems should test for nitrates every year without exception. If your well has never been comprehensively tested, or if it is older or has an unknown history, add a PFAS screening panel — private wells in Pennsylvania have no regulatory monitoring for emerging contaminants. Our well water testing services cover all of these with results explained in plain language. For a full picture of what annual well testing looks like and why it matters, read our guide on annual well water checkups for Pennsylvania homeowners and our article on maintaining your private Pennsylvania well.
What is the best way to get cleaner drinking water in Upper Macungie Township — softener, RO, or both?
For most Upper Macungie Township homeowners on LCA water, the answer is both — and the two systems work together rather than overlap. A whole-house water softener is the right solution for the hardness problem — it protects all your plumbing, appliances, and fixtures from 12 to 18 GPG mineral scale throughout the home. A reverse osmosis system installed under the kitchen sink provides additional purification at the tap, removing disinfection byproducts, chromium (hexavalent), PFAS, and other dissolved contaminants from the water your family actually drinks and cooks with. The softener does not address byproducts and the RO is not a whole-house solution — together they cover the full picture. Our technicians plan and install both in a single visit, with careful attention to placement, drainage, and labeling for easy maintenance. Read our article on how to choose the perfect reverse osmosis system for your home before you decide, and start with a free water test so we know exactly what your water contains.
