Why 1940s Housing And The Former Air Base Shape Pool Care
Willow Grove’s residential character developed largely in step with the growth of the naval air station that operated nearby for nearly seven decades. As the base expanded from its 1926 origins as Pitcairn’s private airfield into a 1,100 acre military installation by 1957, the surrounding community grew alongside it, with homes built primarily through the 1940s and the following decades to house the families connected to the base and the broader Philadelphia area economy. This means a meaningful share of Willow Grove’s residential pool stock has been in continuous service for many decades, carrying the kind of accumulated history in plumbing, surfaces, and surrounding landscaping that newer developments elsewhere in Montgomery County simply do not have.
Montgomery County has documented exposure to 28 major natural disasters over the years, including hurricanes, floods, winter storms, and tropical storms, more than the national average for counties of similar size. This pattern of storm exposure matters for residential pool maintenance because it means pools throughout the Willow Grove area regularly deal with heavy rain events that wash organic material from the surrounding established tree canopy directly into pool water. Combined with decades of mature tree growth throughout the neighborhoods that surround the former base, this creates a maintenance environment where phosphate management genuinely needs consistent weekly attention rather than occasional treatment applied only after algae has already become visible.
