Forrest, your system is beautiful! I received a deal on framed-damaged IBC food grade Totes and have 10 tanks ganged together from our barn roof to our drip irrigation system; we move water up to 300 ft away to garden beds. We also added a Harbor Freight shallow water pump to move water efficiency and have been very satisfied with the results. We reuse pantyhose to filter incoming water, filter again at driplines, and do an annual power wash to remove alge build up and flush to nearby compost pile. Exploring solar pumps also.
