Working mechanism and technical specifications
Laser rain pipes deliver fine spray droplet patterns without high mechanical pressure.
Core technical features:
- Material: Multi-layered virgin HDPE or LDPE enriched with UV stabilizers to resist sun degradation.
- Laser holes: Micro-perforations arranged in zigzag patterns that spray water up to 3 metres on either side (total 6-metre coverage width).
- Operating pressure: Operates efficiently at low pressure (1.0 to 1.5 kg/cm²), running on small 1.5 to 2 HP water pumps.
- Roll lengths and diameters: Available in standard 32 mm and 40 mm outer diameters in 100-metre rolls for easy field deployment.
Ideal crops and agronomic advantages
Rain pipe systems are suited for shallow-rooted, closely spaced field crops.
Crop applications and benefits:
- Vegetables: Onions, garlic, carrots, radishes, and leafy greens benefit from uniform soil surface cooling.
- Oilseeds and pulses: Groundnut, soybean, and gram during germination and pod filling.
- Fodder crops: Lucerne, berseem, and hybrid napier grass requiring frequent light watering.
- Water conservation: Cuts water use by 40% compared to open flood irrigation while preventing soil crusting and seedling washouts.
Installation, flushing and PMKSY micro-irrigation subsidy
Connect rain pipes to standard PVC mainlines using ball valves and grommet take-offs. Flush pipes periodically by opening end plugs to remove accumulated sand and silt. Farmers can avail micro-irrigation capital subsidies under the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) through pmksy.gov.in and state horticulture portals.

Common questions
What is the primary advantage of a rain pipe over overhead sprinklers?
Rain pipes operate at significantly lower water pressure, consume less pumping electricity, and create a gentler spray that does not damage tender blooms.
How wide is the spray coverage of a standard agricultural rain pipe?
A standard 32 mm or 40 mm rain pipe sprays approximately 3 metres on either side, providing an effective wetting width of 5 to 6 metres.
Can farmers receive a government subsidy for rain pipe systems?
Yes, subsidies are provided under PMKSY Per Drop More Crop and state micro-irrigation programs accessible via pmksy.gov.in.
