DIY Drip Irrigation Setup
A drip irrigation system on a 500 sq ft rooftop costs less than a single dinner out and pays you back in two months of water savings. Here's the exact bill of materials.
Shopping list (~Rs 1,800)
- 16 mm main pipe — 30 m
- 4 mm micro tube — 30 m
- 20 drippers (2 LPH)
- 1 battery timer
- 1 filter + tap adapter
Layout
Run the main pipe along your bed edges. Punch a hole at each plant, push in a micro tube, end with a dripper. Cap the line.
Timing
Most rooftop plants need 1-2 litres per day. With 2 LPH drippers, 30 minutes once a day in summer does it.
Maintenance
Flush the filter weekly. Replace timer batteries every 6 months. Drippers clog if you skip the filter — don't.
