In this instructable, I will show how I made a rainwater collection system to water my garden. This helps to conserve water and make good use of a free and renewable resource.
Note that this involves using many different tools and proper safety precautions should always be taken.
Step 1: The beginning - installing the posts
To begin, I laid out a 55 gallon drum on the ground and dug a hole on either side in the spot that the poles (4x4 pressure treated lumber posts) were going to go.
Step 2: Installing the posts continued
With the first post in the ground, I leveled it off with a level and propped it into place with scrap wood. Then, I began to mix the concrete. This entire project took three 50lb. bags of fast-drying concrete. With the concrete mixed to the right consistency, I poured it around the base of the post.
Step 3: Installing the posts continued
The second post went in the same way as the first. From end to end -including the posts, it wound up measuring 39 inches.
Step 4: Installing the posts continued
With the front two posts in place, I took a barrel and laid it back into place. This made it possible to judge where the last two posts should go.
Step 5: Installing the posts continued
Of course, each post got 6 screws in the base to help them stay in the concrete.
All screws used in this project were 2 1/2 inch coarse-thread exterior screws.
Step 6: Installing the posts continued
With the last two posts in, the concrete is allowed to dry and harden.
Including the posts, the front and back both measured 39 inches and the left and right sides both measured 38 inches. However, anybody attempting this should measure and place the posts in whatever configuration that is best.
