Purpose and technical specifications of a diggi
Diggis solve the challenge of rotational canal water schedules (warabandi) by providing on-farm buffer storage.
Technical highlights include:
- Enables farmers to run pressurized drip and sprinkler irrigation systems at critical crop growth stages.
- Can be constructed as a masonry concrete pacca structure or as an earthen pond lined with heavy-duty HDPE geomembrane sheets to prevent seepage losses.
- Minimum storage capacities are defined in state scheme guidelines (typically 4 lakh litres or more).
- Fencing and inlet silt traps must be installed for safety and longevity.
Subsidy eligibility and land requirements
Farmers must meet departmental land and irrigation water criteria to qualify for capital subsidies.
General prerequisites include:
- Ownership of minimum agricultural land (usually at least 0.5 to 1 hectare in canal command areas).
- An authorized canal water turn (warabandi) or functional water source.
- In Rajasthan, applications are routed through the RajKisan Saathi portal using Jan Aadhaar credentials.
- Preference is given to small, marginal, and women farmers with higher subsidy percentages.
Application workflow and physical verification
Farmers submit online applications accompanied by latest land revenue records (jamabandi and naksha trace). Following administrative pre-sanction, construction must adhere to approved dimensional drawings. Departmental agricultural engineers conduct GPS geotagged physical inspections before subsidy funds are credited via Direct Benefit Transfer.
