We have a 17 acre property with gardens, raised beds, a vineyard, and a greenhouse all spread out. There is a well that we just had fixed in the front yard, which we plan on using to irrigate everything on the farm.

Unfortunately the analysis of the water shows very high iron, slightly high manganese, and slightly high lead contents. Normal whole-home water filters from the hardware store need to be changed daily. All "industrial" filters are rated for much higher flow rates than we have.

My question is where should we look for 15gpm filters for metals and sediment? Preferably with automatic backwash.

Thanks.
