Things you need
1 or 2 plastic barrels.
3/4 or 1” PVC pipe. It should be long enough to connect the drip pipe to the barrel and two barrels together.
Silicon Plumbing Sealant.
Drill and hole saw or spade bore bits (1/4”, 3/4” or 1”)
1 or 2 spigots (1/4” ball valve)
Rubber hose washers or o-rings.
Preparing The Barrels
Make sure the barrels are clean so no debris can clogged spigot valves.
Measure your spigot valve connections and drill same diameter holes at the bottom corner of the barrel.
Now drill holes in the barrel the same size as the diameter of PVC pipe as shown in the picture.

Yellow arrows= Holes for PVC pipes
Once done with the drilling, rinse the barrels thoroughly with a garden hose. If not cleaned the plastic debris fallen due to drilling will clog the valves.
Place an O-ring on the spigot and screw it into the drilled hole.
When its halfway inserted apply a little bit of glue on screw threads before tightening it down. Allow the glue to dry for 24 hours before connecting the barrel to a water source.
Connecting PVC Pipe
Use a saw to cut PVC pipe into desirable length to extend the drip pipe. It should reach the barrel and long enough to extend several inches inside the barrel.
The barrel should be elevated enough to place a bucket underneath the valve.
Use glue to secure the PVC pipe and allow it to dry for 24 hours.
If you are attaching an overflowing barrel make sure they are arranged properly. The bottom of the first barrel must be in line with the top of the second barrel.
Both barrels need to be elevated to provide an easy access to the spigots.
Attach both barrels together with a short PVS pipe. Place O-ring at the end of the pipe. Insert the pipe into the barrels. Push the o-rings to butt-up against the barrels.
Use a screwdriver to push o-rings if there is any space between the hole and the pipe.
Seal the pipe and o-rings with silicone sealant and let it dry for 24 hours.
Do not glue the pipe permanently to the barrel. Make it an easy to remove connection so that you can easily clean your barrels.
You can easily renew the connection with fresh o-rings and silicon.
Your catchment system is ready now test it and repair any leaks with silicon.
Now you must be intrigued by what is the purpose of this catchment system? Well, you can use it to conserve water that runs from air conditioners and use it for plantation. Learn Water harvesting and conserve condensate AC water.
