Water is one of the rarest goods, so it is essential to save on the consumption of this resource and its maximum use. An easy way to get the most out of your water is to use a separate rain collector. So that you can do it yourself, we are sharing a guide to making a flexible collector in the shape of an inverted umbrella.
- 1 PVC pipe 80-150 millimeters and two meters long.
- 4 PVC pipes 25-30 millimeters and 3 meters long.
- 8 PVC clips 25-30 mm.
- 20 nuts and bolts
- 8 rings and nuts
- 60 meters of clothesline
- 5mm wide tension strap
- Metal bracelet
- 4 rings
- 7 × 3 meters of waterproof fabric.
- 3 × 3 meter mesh
- 16 cable ties
- 6 shelf supports
- An industrial tank of 1 cubic meter / 1000 liters
- A plank of PVC or wood
You will also need a few tools, mainly a drill, saw, tweezers, scissors, screwdrivers, markers, a tape measure, a sewing machine, tape, and a ladder.
Step by step construction of the rainwater collector.
Step 1: Conduction of water.
Take the larger pipe and drill a good number of holes in the lower part of the pipe and in an area of about a yard. This will allow the water to flow better, while also acting as an additional filter.
Then he makes four holes in each of the quadrants of the tube, first at a distance of 1.2 meters from its end and then 1.5 meters. Make sure the spacing between the holes is the same. Then secure the PVC clips with screws.
Now move on to the four smaller tubes, and in each of them make a hole about 12 inches from the beginning and another about two inches from the end. In these holes you will need to fix the rings later. Before, turn the tube 90 ° and drill again, now 50 cm from the start. Once you have done the operation with the four tubes, connect them with the tension strap through the holes you made at 50 centimeters.
At this point you will need to place the small tubes around the center tube, with the rings facing outward.
Step 2: Design and place the cover.
For the cover, cut the waterproof fabric up to four times following the pattern in the picture and drill a hole in each of the corners. At this time, it will be necessary to pull out the sewing machine, join two pieces of fabric and sew them as if they were a sleeve for the ducts. You will have to repeat the operation four times and, with that, the funnel will be on the inside and the lid for the tubes on the outside.
After this operation, place the fabric on the structure and make a hole in each of the four parts of the funnel, in the lower area, to tie them with a rope and leave them attached to a heavy object, such as a brick, which will help water flow into the center tube.
Once you put the lid on, you can screw on the rings that you had placed on the ends of the small tubes.
Step 3: Wiring to secure the structure.
Cut four cables 3.3 meters long and four others 4 meters long and loop the pliers in each one. The smaller ones you will use for the upper square, in which the water is captured. For its part, with the longer you will fix the structure to the ground.
Now attach the four rings you had in the rings at the top of the four small tubes in the system and also hang the ring with the hole you made in each of the corners of the cover.
With the shorter cables, connect each corner of the covers to get a square shape, and also connect the bigger cables to the corners.
Now that you have the shape you wanted, stretch the net well, cut it to 3 × 3 and secure it through each of the rings and, also, with the tension strap.
Then, he stretches the collector to tension the structure and fixes it to the ground with the 4-meter cables using stakes.
Step 4: Prepare the deposit.
To set up the tank in which the water will be stored, take its cover and make a hole in the center of the same diameter as the central pipe. Once you have it, attach three shelf brackets around the hole to make the structure hold.
Now to go further, create the structure that will occupy the top of the tank, which should be roughly the same size. Again, you will need to make a hole in the middle of the table with a diameter slightly larger than the center tube, so that the shelf brackets can fit into it.
Step 5: Join the puzzle pieces.
With all these steps, it only remains to assemble all the pieces of the puzzle. So, place the tank where you want to place it, screw it on the cover and place over the structure that will cover it, which you will have to fix to the tank with tension straps.
After drilling a few holes in the outer area of the tank cover, secure the center tube and pull the cables through each corner to finally tie them to a stake and anchor them to the ground to completely stabilize the manifold.
This idea will allow you to take advantage of rainwater completely independent of the network. In addition, with it you will gain a shaded area and a table, if you want to use the tank cover for this purpose.
