When we stayed with friends in Thailand a few years ago, they had a sand pre-filter, but I do not remember any details.
We had a large in-ground cistern for one of the houses on my parents land in Eastern Washington. Inside there was a large brick 'beehive' filter over the outlet, since it was filled with irrigation water from a ditch coming from a river. The cistern must have been at least 40-50,000 gallons, since there was no irrigation water available over winter.
