I dont use this for my studio but because we run off a well I havent been wanting to take hundreds of gallons of water for my aquaponics. So Ive used 55 gallon drums as rain barrels which you can find for very cheap and add a bulk head fitting on the bottom. Recently, I took an extra cut IBC tote and placed it near a gutter. The gutter catches an 8 by 8 area worth of tin roof and during the last storm I got 150 gallons worth of water. Totes can be found as cheap as 50 bucks in most areas. You could very easily set one up in an area that is advantageous and have a lot of water at your disposal after a rain. I hooked up a hose so I utilize the gravity and pressure but Harbor Freight sells good water (fountain) pumps at very good prices. Pretty sure a small one inside the bottom of a tote with the outlet directed horizontally to where you need it, through a bulk head fitting that is, and have it linked to a lightswitch as your on/off could work well. Pumps are rated for the GPH and Head lift. Im sure pushing horizonally will give a little bit better performance than pushing out and up the tank then down again.
