I had been wanting to make a video of the water jar construction. I didn't, however, like my videos so well. So, I asked a guy I know in Battambang, to video the construction and make it a time delay video for the viewers. This is what he came up with:
Paul posted a topic in Miscellaneous "Green" TopicsHere is a little information for those who are considering rainwater harvesting. To keep the water that enters your storage tanks as clean as possible (for potable water), you will want a "first flush system" installed. This system takes the initial water that hits the collection area (your roof) and routes away from your storage tanks. In order to make sure your roof has been washed clean of various debris, including animal feces, twigs, leaves, pollen, etc., it is recommended that you divert a minimum of 1 US gallon (~3.8 liters) of water for every 100 square feet (~9.3 square meters) of roof collection surface that you have. Pipe size and length, for the diverter: 3" PVC will take about 33" (~84 cm) of pipe to collect one US gallon of water. 4" PVC will take about 18" (~46 cm) of pipe to collect one US gallon of water. (This is the diameter I used.) 6" PVC will take about 8" (~20 cm) of pipe to collect one US gallon of water. --------------- At the moment, I have 20 square meters of collection area. That may not seem like much - well, it isn't, really. But, since mid October, our harvesting has completely filled 3 - 1,050 liters storage tanks. (One tank was about half full when we began, though.) We are in the process of adding another 30 square meters of roof, part for a front porch and part to cover a kitchen and bath. 50 square meters of collection area is going to come in pretty handy come next rainy season. I am already looking at a 10,000 liter (~2,641 US gallons) blue polypropylene storage tank, for expansion of the system. I estimate that tank, alone, will store a one month supply of water.
