You need to be more specific about your situation. It sounds like perhaps you are unclear as to what is involved. There isn't a rain catchment superstore because no 2 people go about it the same manner, but rain catchment has about 4 or 5 different aspects. You need a roof or catchment surface, a way to direct runoff (usually gutters), a storage system, and an outlet for the catchment to be used. The outlet can be as simple as a pipe to a tree with a valve, or as complex as hooking it up to sprinklers or a drip line and run it to multiple plants.

I'm part of a ski club which uses a building only in the winter. We are looking into using water catchment as the supply for the building.
The building has a metal roof, so it should work well for that. I estimate we need between 5,000 and 7,000 gallons of water. Given our annual precip, we will be fine.
I'm looking for places to purchase drain cleaners, and filters for between the tank and the usage. We don't have a large need for potable water, but we do need a few hundred gallons a year.
Thanks for any sources you can point me toward.

Typically leaves are flat and thin, thereby maximising the surface area directly exposed to light and promoting photosynthetic function. Externally they commonly are arranged on the plant in such ways as to expose their surfaces to light as efficiently as possible without shading each other.
I spent a bit of time yesterday researching this same topic. I went to craigslist and found a lot of farmers trying to sell their old water storage tanks. Ranging from plastic to those metal ones on a pedestal. They were selling anywhere from $100 to $350 for 200 gallons- 500 gallons. If you use an existing gutter then pvc and mesh would not be more than $20 to finish it. Now getting it piped into the building would depend on what you have existing and how far it would need to go.
Hope that helps!
You will need to either bury the tank(s) below the frost line or put them inside a heated structure to keep them from freezeing at your ski cabin. If the catchment is at your cabin, then you need something to move the water into the cabin such as a pump. This is not a do it yourself progect, you will need professional grade building done. 7000 gallons of water will weight 27 tons, plus tank, plus pumps, pipes and plumbing.
There are too many new and different mistakes out there waiting to be made to be wasteing your time repeating the same old mistakes.
