This is a custom system I designed to collect the rainwater coming off my roof and have both the ability to store the water and distribute it without attaching any temporary piping. My apologies in advance that I don't have pictures showing the step by step construction - I only discovered this site last night!
Step 1: Get Your Materials and Tools
It's a pretty simple collection of materials - most of which can be found at your local hardware store. I did a little hunting around to find an appropriate rain barrel - ended up getting one from an eco-store here in Calgary.
6 - 2x4 studs (each 8 feet long)
Approximately 100 - 3" long deck screws
55 gallon rain barrel
Sections of 2" central vacuum tubing (could substitute plumbing PVC or ABS pipe, but they cost 2x or 3x the price). Length determined by the distance you need the water to travel - I needed 6 sections.
Assorted couplings, end caps, 90 degree elbows, 2" ball valve, 1 'Y' section, and two threaded adapters to connect into the rain barrel.
2" plastic straps to affix the pipe to fence.
1 10' length of 3" pvc pipe & assorted 3" couplers/elbows
Optional stainless steel screws (or substitute the deck screws)
'C' shaped straps - number depends on the length of your delivery pipe
Saw (I used a mitre saw, but a hacksaw would work)
