How do I make a homemade swimming pool using a pool liner?

Are you a qualified pool builder. Do you have all the necessary permits? Do you know the N E C swimming pool electrical codes for building a pool shell? If this is an above ground vinyl pool ~ Do you know how to level or prep the ground under and around the pool? Are you sure that the materials that you plan on using are strong enough to handle the stress or the weight of the water plus the surges of water as someone does a canon ball into the pool? Please, do your homework and research before attempting the task of constructing a pool. You have to figuring out what the hydraulics configurations are for Plumbing the pool, filter, pump, heater, skimmer, main drain. How are you going to support the walls ~ from either collapsing inward or outward once the water is added? This is not a job for a beginner.
