Rain Harvest

I’ve been working on a new project to collect rainwater. Call me crazy, but getting huge plastic tanks for this is a long-time dream come true. Here’s what I did:

  • Identify an appropriate spot for a 300-gallon IBC tote (a cube container with 3.5-feet long sides). It should be under a rain gutter downspout that gets good flow, and somewhat out of view to reduce the eyesore (ie do not block windows).
  • Obtain two IBC totes from Craigslist. Request delivery (these won’t fit in an SUV). Make sure they are food-grade/food-safe and did not formerly contain toxic chemicals. Water collected in these totes will be used to irrigate vegetable gardens and provide drinking water for chickens. Seller confirmed they are from a dishwashing business and are safe to use.
  • Clean the inside of an IBC tote (or ask seller to do so) with a pressure washer. Empty out the water. Make sure the spout works.
  • Obtain & use a T30 star driver bit to unscrew and remove the top two metal bars of the cage. DeWalt bits are good quality. T30 star bolts are standard on IBC totes. You can look for the letter “T” on the bolt to check.

  • Remove plastic tote from the metal cage.
  • Set newspaper or cardboard under the plastic tote. Wear a mask to reduce inhalation of paint fumes. Paint the plastic tote so that it is opaque, which will inhibit algae growth. Look for lighter areas & thoroughly coat with paint until light doesn’t shine through. Using “Rustoleum Comfort Grip” or a similar product is optional but makes extended spray paint sessions significantly more comfortable for the hands.

    I used 3 spray paint cans of “Rustoleum 2x Satin Finish” in color Colonial Red to fully coat one tote, and the red color will make the tote blend in slightly with the red brick of the house. I also got the same spray paint in “Claret Wine” (a slightly darker, purpler tone) for the second tote. This one requires 5 cans to fully coat. Who knew some colors take more quantity to cover a surface than others.
  • Let the opaque painted tote cure and dry under a covered, sheltered area for 3-4 days. The longer the better.
  • Set up cinder blocks around the base of the IBC tote’s designated location. 6 blocks set edgewise (so holes are facing up, not the sides) sufficiently form the perimeter. The IBC tote spout is very low so raising it up on blocks will give height clearance to fill a jug and let water flow down hose by gravity better.
  • Insert plastic tote inside of tote cage. Set up tote on top of cinder blocks. Even with 2 people, the tote is heavy!
  • Cut wire mesh screen (the kind used for window screens) and place over the top opening of the tote. Cut a little bigger than needed. Secure with the ring-lid or bands. This screen is fine enough for most debris, and mosquitos cannot enter through the holes and lay eggs in the collected water. (The biggest enemy will be algae. An occasional pressure wash inside will help).
The screen would be better under the black cap, not temporarily secured with rubber bands which will get brittle from the summer sun. The black cap was too tight to unscrew for the time being.
  • Set up rain gutter downspout to flow into the tank through the screen. Pour a jug of water down the spout to test that the downspout is positioned well, secure, and water flows into the screen.
  • Set up an overflow system in case the tote fills up. For example, drill a ~1″ hole on the side, near the top, with a hose through this hole that goes out several feet away from the home and foundation.
  • The IBC spigot is very large and does not fit standard hoses. Set up a coupler and standard hose-size brass spigot.
  • Enjoy collecting and using rainwater! It’s better than city-treated water for watering plants because it has dissolved oxygen and is not treated with chemicals like chlorine and fluoride. This is better for the garden. Total cost including tools was about ~$336 and there are city rebates available. After the initial set up, it also means a free supply of water!

Fort Knox Chicken Box

Last night I watched Life Below Zero, where subsistence fishers and hunters carve out life in Alaska. Just one episode makes my upcoming project of building an enclosed, walk-in chicken run and secured coop seem much less daunting than it did two days ago. This coop run in this video is my model. I call this project “Fort Knox Chicken Box”.

A pigeon-sized hawk attacked my littlest hen last week and severed her neck. I grieved, then resolved to secure the roofless chicken run. I’m chipping away at the daunting fear with the passage of time, research, watching run build videos, procuring tools, and exploring our premises to see what tools and scrap wood the previous resident left behind. I’m one shovel and YouTube video in. Measurement and wood to come. 50-foot hardware cloth roll and pneumatic staple gun on the way.

I noticed that people with an unenclosed, open-air (roofless) chicken run:
i) often have a dog trained to guard the chickens during the day from hawks, weasels, etc.
ii) accept a non-zero mortality rate of their flock. One book says 5% each year.

In the mean time, I am that guard dog, supervising the hens’ free ranging until it’s their bed time.

This is an ambitious project, but I want the hens to roam safely, and to learn construction along the way rather than getting on Carolina Coop’s 4-month-long wait list for someone else to do this.

Steps I will take:

  1. Measure desired perimeter of enclosed run. Divide border into about 6-8 sections. Mark corners with stones or upright sticks. Mark where door will be positioned.
  2. Measure each section length. These will determine the lengths needed for 2×4 horizontal beams to go about 3-feet up the side and around the top (to hold the roof).
  3. Set up string line around border, anchored beyond stone markers so they don’t interfere when digging holes at the markers. Use extra cotton twine on hand. (Optional: Use leveler to ensure string line is flat.)
  4. Obtain wooden posts. 4″x4″, about 7 feet tall. They will be buried 1 feet and make a 6 foot walk-in height.
    Obtain “quick mix” concrete and a large tray for mixing.
  5. Obtain or find 2×4″ wood pieces around the premises, and cut to correct length in step 2.
  6. Mark depth on wooden posts that they will be buried.
  7. Apply waterproof stain or primer + stain/paint to all wooden posts and side pieces.
  8. Dig holes where there are markers.
  9. Set posts into holes. Check that horizontal section length still matches step 2.
  10. Mix concrete in tub. Can use rake.
  11. Shovel/scoop concrete into holes. Line up posts against the string line.
  12. Check vertical alignment with a leveler.
  13. Use string line and visually check that they are aligned.
  14. Let the concrete dry and set according to instructions.
  15. Install horizontal wood mounts on the posts along top and middle. Mount on corner sides for the corner posts, and on opposite sides for the side posts.

Next steps will involve hardware cloth on the walls and along the floor, choosing roof type and installation, and the entry door. Stay tuned.
