I really enjoy my gardening and learning more with my projects – especially as it relates to rain drip irrigation and square foot gardening. There is always something to learn. Yes, the setbacks are disappointing but there are occasional wins and doing and sharing these with my daughters is really fun and provides us some time together. Square foot gardening recommends that I hand water the plants every day but my busy schedule doesn’t allow for that. I also installed a rain water collection system last Fall and I really want to see if it is useful for garden drip irrigation in my container gardening. I added some piping from my rainwater collection system to feed a drip irrigation system and built a rain drip irrigation system.
Permanent Piping for a Rain Drip Irrigation System
I tested my rain drip irrigation system with a long water hose to make sure that I sufficient water pressure at the hose bib to drive the drip irrigation emitters. Once I determined that the combination of approximately 6 feet of downhill slope coupled with 10 feet of water column volume was enough to drive the emitters, I installed permanent PVC piping down to the container garden to install a permanent hose bib. My water supply for my drip irrigation garden system is now fully implemented.

Rain Drip Irrigation Drainage Valve
We don’t often have very cold weather in Texas but it does freeze occasionally and I only buried my water supply pipe a few inches under the surface of the soil. I don’t want a freeze to burst my pipes and destroy my rain drip irrigation supply line. So, I put a hose bib at the end of the rainwater collection system supply line so that I can drain my rain drip irrigation system each Winter. There is only about 150 feet of pipe so I think this simple solution will be fine.
Splitter for Garden Drip Irrigation Options
I installed a simple hose bib splitter at the hose bib of my rain drip irrigation system. I’ve had trouble with hose bib splitters in the past but I think I was trying to do too much with them. This arrangement is much more simple. I have one side of the hose bib splitter to feed my rain drip irrigation system and the other side feeds a very short hose for incidental watering as I need it. The hose bib needs to be full on to supply enough pressure to drive the emitters in the drip irrigation garden system.
Drip Irrigation Garden Details
I used the separator lattice from square foot gardening as the supports for my rain drip irrigation master hose. Each square in my garden has a dedicated small hose and emitter. I can vary the emitter volume and count to supply a sufficient amount of water for each different plant type.
Rain Drip Irrigation Full Installation
The full rain drip irrigation system makes a very simple U shaped loop across the top of the square foot lattice and provides a dedicated drip irrigation garden feed to each square in the garden. I’ve come to appreciate simplicity in gardening as each time I’ve tried something complex, it seems to fail. Rainwater fills my collection tank and now provides daily water to my square foot garden through the rain drip irrigation system.
Summary of Rain Drip Irrigation Installed in Square Foot Garden
I tested my rain drip irrigation system with a simple garden hose and then installed permanent, underground piping to my square foot garden. I also installed a drain valve and a hose splitter at the garden hose bib for options in my garden drip irrigation system. I used the lattice boards from square foot gardening as a support for my master drip irrigation garden hose and then installed a dedicated feeder hose and emitter to each square. My rain drip irrigation is installed and working nicely with a timer controlling the daily watering times.
