Howdy TDR Friends,
This is a great thread and still relevant... When I built my shop, I realized I had great opportunity to capture, store and use rainwater. In San Antonio TX area we are always dealing with drought, so I designed and installed one 1600 gal tank, then a second, then a third. They've held up pretty well, but needed some maintenance. I'm reconfiguring my three themp rainwater capture since adding another cover to my mancave/shop.
Had to crawl inside one I had damaged with the frontend loader of my tractor 10 years ago... a truly redneck repair for the 6 inch gash. Used rubber dually mudflap, NP-21 industrial adhesive, and 1inch sheet metal screws. Held good for 10 years, but started seeping water this year. Drained it watering outlying trees, turned it over, crawled into it two days in a row, and sprayed layers of Flexseal. I think it's good now.
I messed up when buying the third opaque white tank versus a black one cuz it was $100 less at tractor supply. It worked pretty well except it became a algae breeding tank. Drained it watering trees as well, turned it over, crawled into it, and pressure washed it two days in row. Seemed the algae almost grew into the plastic.. Got it all cleaned and going to paint it black. That's what I'm working on now.
Another part of the project is installing leaf guard on the shop 4" rain gutter. It catches Mesquite leaves and Texas Ash leaves from the other side of the shop and clogs up the down spouts. That'll be next.
So, didn't think about posting this project and taking pics. I'll take some today and post.
Keep up the diligence and stay healthy as we all make the best of this pandemic.
