A Green way of using rainwater with the convenience of city water. The attached solar regenerated pump enables you to water plants with pressure, even when the water in the barrels falls low enough that it barely passes the level of the faucet. The sun-warmed water also aids in the growing of plants as it does not shock them. The twin 85 gallon barrels are raised onto a very sturdy 4x4 box assembly from recycled wood, held together with new carriage bolts because the total weight of all the water when full is approx 1700lbs. This frame is resting on eight 2 inch thick 18 inch square cement pads to prevent sinking. The barrels are raised to increase the head pressure and decrease the work load on the pump.
Vote for me if you think my idea is worth passing on to show people being green doesn't have to mean sacrificing quality or convenience . Thank you for taking the time to look at my instructable!
Step 1: water supplied from mother nature
link barrel to downspout. ensure top of barrel remains below level of water entry. I found the Watersaver attachment for the 3x4 downspout pipe works perfectly. In order to enable adequate water flow to the barrel I adapted the Watersaver attachment by drilling out the side and adding a flange for a 1inch PVC fitting. I sealed this by using a rubber gasket and additionally using a silicone sealer. Ensure there is a downward slope between the downspout and the barrel entry.
