Owner installation requires permitting-authority approval, ownership of the home and land, suitable skills and equipment, no development for sale or lease, and compliance with permitting and maintenance requirements5. Secondary-treatment or drip-irrigation systems require inspection every 4 months by a valid maintenance company unless homeowner maintenance is allowed14.
