Average water table depth in West Texas is 4.2 meters, and water weighs about 9810 N per cubic meter. If you dig a pit 1 meter deep to store the water at ground level, that reduces your height above aquifer to about 3 meters. You then can store about 30,000 J per square meter of pit area.
For perspective, that is about enough energy to keep a lightbulb on for 10 minutes. It is about .008 kWh. Average household energy consumption is about 30 kWh/day. You’d therefore need a pit that takes up about an acre to store enough energy to power your house for a day. This may interfere with your farming plans somewhat.
