Levittown, PA Landscaping Rules: Rainwater Harvesting (2026)

Pennsylvania has no state-level restriction on rainwater harvesting for residential use. PA follows common-law surface water capture rules that permit landowners to collect precipitation on their property without prior appropriation (unlike some western states). In Bucks County, residential rain barrels (typically 50-80 gallon repurposed food-grade drums or commercially manufactured units) are installed without permits in virtually all municipalities. Larger residential cisterns — 500-5,000+ gallons for whole-house non-potable use — may trigger PA Uniform Construction Code review if they constitute a structure or connect to plumbing. Plumbing cross-connections with the potable water supply require backflow prevention devices per PA DEP and local water authority requirements. For properties on private wells in upper and central Bucks, rainwater can supplement irrigation without regulatory impact. PA DEP permits are required only if rainwater systems are part of commercial stormwater management plans or potable water treatment. The Bucks County Conservation District promotes rainwater capture as green stormwater infrastructure, often in conjunction with Act 167 stormwater management credits. Municipalities including Doylestown Township, Warwick, Newtown Township, and others have offered rain barrel rebate or workshop programs. HOAs in planned communities (check Newtown Grant, Heritage Creek, Traditions of America) may restrict visible rain barrel placement — typically requiring location at the side or rear of the dwelling rather than streetside. Rainwater for potable use (drinking, cooking, bathing) requires treatment systems meeting PA DEP Safe Drinking Water Act standards (25 Pa. Code Chapter 109).
