We bought our house here about 1 1/2 years ago and had most of the old catchment replaced (except the pump and the plumbing). We got a 10,000 gallon tank for 5 people and we've haven't had to fill it yet. We have 3 carbon filters (of decreasing sizes) and a uv filter. I change the carbon filters about once a month (in theory). And you are supposed to have your catchment tank cleaned once a year. (that's on my to do list) And we have never added chlorine. (is that required?) oh, our tank is covered with one of those umbrella-looking systems. And we drink the water. Never had any problems. That I know of....
