Place one end of the water hose in the pool. Lower it down so that it is near the bottom of the pool. Bring the other end of the hose to where you want to drain the water. You can use more than one hose if you want to drain the pool faster. Siphon the water out of the pool by placing your mouth on the end of the hose and sucking several times until the water comes out. Spit out the water. Do not swallow it.

Understand that once the water begins to flow, it will continue to flow until the air is at the end of the hose in the pool. This way, you will allow the natural laws of gravity and air displacement to work to drain the pool.
