This makes filling watering cans a lot easier. The higher you're willing to put the barrel, the more water pressure you can achieve. Step 2: tools for the job. I made my first rain barrel using a dremel tool for cutting the holes, but I found that the results were not very precise. I purchased a 10-piece hole saw from Harbor Freight for about 8 and it made the job significantly easier. The remaining tools I had in my collection already. The only really unusual tool is the. Clamp Tite tool i used for fabricating the hose clamp using stainless steel locking wire.

Components for the rain barrel (parts i used and approximate cost in parentheses food-grade watertight barrel (220 liter Greek pickle barrel, 20). My local hardware store happens to sell used food-grade barrels during the summer. Screen to filter incoming rainwater (3" kitchen sink strainer, 1). Overflow fitting (Right-angle 3/4" inner diameter 1-1/2" male npt to 1" hb fitting,.75). Overflow hose (1-1/4' flexible hose, 6 ft, 3). Bulkhead fitting (Bulkhead fitting, 1-5/8" outside diameter, npt female threads to accept a standard 3/4" spigot, statement 8). Nipple to connect bulkhead fitting to shut-off valve (3/4" male npt to 3/4" male ght, 1) shut-off valve (lee valley, straight shut-off valve, 13 hose union gasket market (lee valley. O-ring washer, 10 for.25 optional: quick-connect fitting (lee valley, brass quick coupler, 10). Dry fit all components once collected to make sure all threads match and everything fits as expected. For the base of the barrel, i used a couple of cinder blocks and a piece of flat blue stone i had in the yard.
Note: It is not recommended to use captured rainwater for drinking, but the food-grade component ensures that the barrel has not held contents that could damage the water supply or plants, or be absorbed by plants and then ingested when those plants are eaten. I use it for the following: Water the garden, refill the toilet toilet tank after flushing. Various household construction and cleaning uses. The components cost between as little as 25 to more than 60 depending on what you're willing to spend. Including the lee valley components below, the total came to about 40 and the barrel was another. (The optional quick-connect coupling would add another.) you may be able to source less expensive components. There are various acronyms used with plumbing fittings, and I will list the ones i used here: npt - national Pipe Thread, ght for - garden Hose Thread, hb - hose barb.
Screw the shmoop cover on and place the table top on the barrel. Fix the tabletop with tension straps to the barrel. You will have to drill some holes into the table top, close to the frame around the barrel. Place the tube in the barrel and pull at the wires at each corner. Once the barrel is in place, you can attach the wires to a picket and fix them into the ground. now everything is set up, you're ready to harvest some rain! Share recommendations Creative misuse contest Game life contest Water Contest. Step 1: Parts List and Materials. The rain barrel starts with a food-grade barrel, modified to accept and store rainwater run-off, discharge excess rainwater once the barrel is filled to capacity, and dispense rainwater for watering the garden or for whatever use you find for captured lab rainwater.
Step 6: cover take the cover from the reservoir and make a hole in the middle with about the diameter of the central pipe. Attach 3 shelf supports ( L ) around the middle hole (every 120). These will keep the structure straight into the barrel. Use the same nuts and bolts as in step. Note mark and attach the shelve supports onto the cover with the central pvc tube already in place. Because of this the pvc tube will fit exactly between the shelve supports. Step 7: table top now make a table top at about the size of the barrel (1x1,20 m). Make a hole in the middle of the plate that has a little larger diameter as the central pipe so the shelve supports can pass through. Step 8: assembly put the barrel in place.
Notes on the objectives of the rain water harvesting
Next step: take 4 key rings and attach them each to an eyebolt at the top of the small pvc tubes. Attach the metal hole from the canvas to the ring in each corner. Connect the 4 corner rings onto each other, using the 4 short wires (3 m) libraries to become the square surface. Connect the 4 remaining wires (4 m) to the ring in every corner. Stretch the net and cut it to size 3x3. Connect the corners of the net to the rings on every corner.
After this you can attach the sides of the fabric and the net with the wires, using tension straps. You can make some holes in the upper side of the canvas for the tension straps. Now pull the flexible catcher open until the fabric is under tension. Then anchor the long wires (4 m) into the ground using pickets. Note if the wires between the 4 small pvc tubes are too loose you can adjust the length until it's under enough london tension.
Put the fabric funnel onto the structure. Make a hole in the 4 flaps on the bottom of the funnel. Lace these holes together using the clothesline and attach it to a brick - or other weighty object - and drop this in the central pipe; this will guide the canvas into the central tube and keep it there so the water will flow into. When the canvas is attached onto the frame, you can screw the eyebolts back into the end of the small pipes. Make sure they face the same direction as the ones at the bottom.
Note use a strong needle (for jeans) because the fabric is quite tuff to stitch. A double stitching line / pattern is recommended! Step 5: wires cut 4 wires at the length of 3,3 m and 4 at the length of. Use the clamps to make a loop, the loop-to-loop should be about. The 4 short wires are used for the square, rain catching, surface on top. The 4 long wires are used for anchoring the whole structure to the ground.

Step 4: canvas cut out the canvas pattern (drawing) four times. For smaller models you can downsize. Make sure you have a hole in at least 1 top corner of each part. Sew two pieces together on both blue and red line hotel (for the tube sleeve). Repeat this step three times until you have the four patters sewed onto plan eachother. Now you should have the funnel on the inside and tube sleeves on the outside. If you have remainings of the fabric at the sides, you can cut them off.
Drill a hole through the pipe at about 30 cm from the start of the tube and another at 2 cm from the end. Now rotate the tube 90 and drill another hole at 50 cm from the start of the tube. Attach the eye bolt on the 30 cm and 2 cm holes. Now snap the small tube onto the large tube, eye bolt turned outside. Repeat this for the other 3 pipes. Connect the 4 pipes by putting tension straps through the 8 holes at 50cm from the start. This will keep the pipes from turning around too much. Also attach metal straps around the pipes for extra strength / over safety.
every quandrant of the large tube at 1,2 m from the bottom and another 4 at 1,5 m from the bottom. Make sure the distance between the holes is the same everywhere. Attach the tube snaps ( C ) on the holes with bolts. Notes, drill the hole with a drill size that's.5 mm smaller than the diameter of the bolts you're going to use (self-threading). Use countersunk bolts to make sure the bolt is secured in the pvc snaps. Otherwise it will be difficult to snap the tube into the connections. Step 3: small tubes ( Ø 25 - 30 Mm, 3 M ). The 4 pvc tubes are the same.
Someone to help you, with the formulas below you are able to roughly calculate how much surface you need. Plants 20 l/m per week needed (average). Garden space, gS, rainfall (average) 17,5 l/m2 per week (local weather site). Surface needed ( 20 l/m x gs ) / 17,5 l/m collector surface needed. Note, the maximum surface of one collector is 6 m resume (restricted by standard lengths of tubes max 3 m). If you want to go bigger, we suggest that you build more than one. When you go for a smaller one, you should scale down the sizes and distances. But never the amount of pieces needed.
