Serving Upper Macungie Township

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.
