If you lack a mechanical pump, you can drain standing water using a gravity liquid siphon with a standard garden hose. Submerge the entire length of the hose underwater until all trapped air bubbles are completely expelled from the line, tightly seal one end with your thumb, place the sealed end lower than the water source into a designated drainage area or sink, and release your thumb to establish continuous downward flow. You can verify successful siphon operation by observing steady, uninterrupted water discharge through the hose.
