I have some question regarding my rain catch system

Hello

I have a 550 gallon horizontal leg plastic tank that I plan to use with catching rainwater for our sole water supply (minus drinking). I will be locating it up the hill from where we will be living. I don't know the exact elevation. But I suppose it will be like at least 20 feet higher than our faucets and at least 50 feet away. I plan to bury the tank halfway into the ground in hopes that will keep it from freezing in the winter. We dont usually have crazy winters in KY. But its always possible. Additionally, I plan to build a pole storage building around it with a nice roof for catchment. As well as room for some personal storage. At least until I get a second building put in later in the year. Anyway. The roof will be your typical metal roofing. I am thinking of using a mesh guard for the gutter. I prefer a closed system whenever possible. I will put in a first flush and just make sure I drain it. Would like to figure out an automated way of doing this if its possible. The bottom line is that I would like to get the water as filtered as possible PRE TANK. Which is course would require a rapid filtration process consider hard rains are a grande opportunity. I am a bit lacking in the knowledge of POST TANK filters. Since we are using a gravity system for our needs, I don't want to cut down the pressure too much. And I suppose a filter might become a hindrance. Furthermore, I would like to just pipe the water three feet underground from the tank to a simple water hydrant. Then hook a hose from that to run to our camper city hookup. But I dont know if that will cut down the pressure either.

Anyone knowledgeable in what I am trying to accomplish? I would appreciate any advice. Thanks. -- Joe

Jake S. : A quick Google search using "Images of Rain water catch system diverters " will get you to several useful links !

Your post tank filter can be as simple as a sealed charcoal filter that has a female hose fitting on the end that screws onto
the Hose bib's* male hose fitting the other end will accept the female end of your garden hose you are using to supply your
campers city water hook up ! Keep this line as short as possible as initially this will be your greatest reducer of flow/pressure !

Late note : The type of in-line shut off you want for Your camper will usually be found with one end threaded to 3 / 4 inch
Female Iron Pipe, 3/4'' F.I.P. or 3/4 inch Male Iron Pipe 3/4" M.I.P. and the other end Threaded to 3/4 inch Male Hose thread,
This is generally called a Hose Bib !

You probably have Two of them as shut off valves supplying water to the back of your washing machine ! A.L.
