I've searched this sight so as not to start a new thread but I can't find what I am looking for which is a book or two on water harvesting. One was titled something along the lines of "water harvesting in arid zones" and the other had something to do with ponds (apparently popular due to how many times I saw it mentioned). I know what I am asking for is a stretch, but does anybody know the name of these books, or any other good books along the same topic? Thank you all in advance!!
