An irrigation system for a palm tree is installed within a treewell grate surrounded by finish paving and finish grade. Four Rainbird 1401 bubbler heads are positioned around the tree root ball and connected via polyvinyl chloride schedule 80 nipples and polyvinyl chloride schedule 40 pipe with ninety-degree socket-by-threaded elbows. Lateral line pipes and fittings feed the assembly, connecting through polyvinyl chloride schedule 40 pipe to the control valve and sleeves leading to other irrigated palms in grates.
