Rainwater harvesting is legal in Tinley Park and encouraged for outdoor irrigation use. Illinois law (415 ILCS 56, the Illinois Plumbing License Law and related rainwater rules) allows residential rain barrels without permits for non-potable outdoor use.
Illinois generally permits rainwater harvesting for outdoor, non-potable uses such as lawn irrigation, garden watering, and landscape maintenance. Under 415 ILCS 56 and Illinois Department of Public Health plumbing rules, residential rain barrels collecting from rooftop downspouts do not require permits for outdoor-only use. Harvested rainwater cannot be connected to indoor plumbing or potable water systems without a licensed plumber and Illinois Plumbing Code compliance. Cisterns and larger collection systems for indoor use require permits and cross-connection protection. Tinley Park residents can use rain barrels alongside village water to reduce consumption during drought restrictions. Contact Tinley Park Public Works at (708) 444-5500 or Illinois DPH Plumbing Program for larger systems.
Cross-connecting rainwater harvesting to potable water lines without approval is a serious Illinois Plumbing Code violation carrying fines up to $5,000 and mandatory disconnection. Outdoor rain barrel use without indoor plumbing connection is generally compliant.
