Serving Devon

Devon, PA is one of Chester County’s most recognized communities, a place where the historic Devon Horse Show and Country Fair has anchored the neighborhood since 1896, making it the oldest and largest outdoor multi-breed equestrian competition in the country. Situated in Tredyffrin and Easttown Townships along Lancaster Avenue (Route 30), Devon 19333 sits at the heart of the Main Line. Residents and visitors gather at Devon Yard, a lifestyle destination at 138 W Lancaster Ave featuring Terrain Cafe, Pizzeria Vetri, and Anthropologie. Just over the township line, St. Davids Golf Club in Wayne offers a celebrated Donald Ross-designed course that has been a community landmark for generations. Life on the Main Line carries a certain polish, and Devon homeowners increasingly expect the same from their water.

Devon is served by Aqua Pennsylvania’s Pickering Creek surface water treatment system. Pickering Creek, along with the Brandywine Creek system, supplies water to communities across Tredyffrin and Easttown Townships. Water hardness in this area typically measures 7-10 grains per gallon (GPG), which falls in the hard classification and is sufficient to leave scale on fixtures, reduce the efficiency of water heaters, and cause dry skin and flat hair after showering. If your dishwasher is leaving spots on glassware or your soap never seems to lather fully, hard water is likely the cause. A professionally installed water softener is the most effective long-term solution for protecting Devon homes and appliances.

Aqua Pennsylvania uses chloramines as its primary disinfection method across much of its southeastern Pennsylvania service area. While chloramines are effective, they produce disinfection byproducts including total trihalomethanes (TTHMs) and haloacetic acids (HAAs) that many Devon families prefer to remove at the tap. At the same time, PFAS (per- and polyfluoroalkyl substances, also called “forever chemicals”) have been detected across Chester County waterways, including Pickering Creek and the Brandywine system. Aqua Pennsylvania actively monitors and invests in treatment upgrades, but many households seek an added layer of protection at the point of use. Our professional water testing service gives you specific, measurable data. Learn what a free water test covers so you know exactly what to expect before we arrive.

Devon’s housing stock ranges from historic estates to newer construction, and water quality concerns vary by home age and plumbing type. Older homes may have copper or even lead-containing solder in their plumbing that is more vulnerable to corrosion from chloramine chemistry. For those interested in comprehensive drinking water protection, our reverse osmosis systems are NSF-certified to reduce PFAS, TTHMs, and chloramines to near-undetectable levels. For homeowners buying or selling property in Devon, our real estate water testing services provide the documentation lenders and buyers need.
