I looked through some old posts on this forum about rainwater harvesting, but would like more information if anyone has some to supply.
I have a huge roof with gutters that, while not perfect, certainly collects lots of water when it rains. I also have several very large garden beds I'd like to water.
I already know I will buy four 75-gallon water barrels from my city (one used for grey water collection), but I also want to install a rainwater tank and I have (at most) about $1,500-$1,800 to spend on it. Obviously, I want the biggest bang for the buck: durability, easy of maintenance, etc. No pump. I obtained one estimate from a company who wanted $5,600. for installation/set-up. This was more than I could afford. However, I have a friend who is a building contractor, and he's willing to help me put one in for considerably less.
Has anyone here installed their own tank and if so can you give me pointers about this? Pros/Cons of plastic versus metal with a liner, placement of the tank, pad for the tank, cleaning the tank, etc.
