Sanitizing the rain tank
Mr. Dogpatch drew the rain tank down for the first time since installation this last week. Our guide to installation said to leave the tank alone to allow the biofilter to develop, but we thought it was time. So he dumped a gallon of bleach in, let it set for a day, then opened the valve. It got a thorough pressure washing and some of the intake plumbing was taken down and cleaned. No sooner did he get finished than this fabulous two day rainstorm hit, delivering over 600 gallons of fresh rainwater (so far).
The tank has saved us a few times when the power went out and we couldn’t pump the deep well (hopefully the new generator will alleviate that problem). We bring the water into the house in five gallons jugs, treat with a tablespoon of bleach, then run through a sediment filter and a Berkey tabletop filter. The horses drink it straight!
We were both very nervous, pouring that resource onto the ground to clean the tank!
