Hi Everyone, Can someone clue me in regarding the viability of catchment water systems? If you are using such a system, are you using for both family and livestock? How large of surface area would we need to collect enough water for a family of 4, 4 head of cattle, and a few chickens? We live in zone 8 and get anywhere from 30-48 inches of rain a year ( depending on whether it is a dry year or not ). As Always, Many Thanks For Your Help and Happy Fourth of July !!!!!!!
