I need a comprehensive plumbing plan for a swimming pool that measures 60x30 feet. The pool is partially elevated, with 2.5 feet built above the ground, and features two distinct zones: a 15x30-foot area for kids with a depth of 2.5 feet and a 45x30-foot area for adults with a depth of 4.5 feet. The deliverable includes a detailed pipeline design, machine room layout, and the integration of the following components: - Sand filter - Pump - Skimmers and inlets (evenly distributed around the pool) The plumbing plan should be provided in both 2D and 3D formats. I prefer PVC as the material for the pipelines. Please ensure the design is practical, complete, and adheres to industry standards.
