not having read all the posts here, ::
a tank with a bottom outlet or a hand pump from above.......
you can build your own tank from various materials..........2x4/6 ,3/4" plywood, pond liner, plastic sheeting, even chicken wire in a circle, etc. some informative videos on you tube.
i have built two 1500g / and a 600g tanks..
cheaper than poly tanks.
store rain water or water from the well for those times.
i have 20,000g storage for my rain collection.......still not enough storage. i watch rainwater flow out overflow on tanks down the hill yearly.
i live in the high desert of new mexico.
peace and goodwill to all.....
