With a severe drought, and water in San Diego countty at a premium, we are going to install a 1000 gallon underground water tank, pump, and flitration so a client can use the water on thier landscape and small fruit grove. The home is being replumbed so the gray water does not enter the sewer/septic. Herezz the question. Do any of you know of a system comes as components, be engineered, so all I have to do is connect the pieces? If not, can you suggest what ad where to start looking for? I have done a few google searches, and came up with little to no info. Thanks for the help in advance.
