Tubewell: Shallow Groundwater Tubewell

Tubewell

The Shallow Groundwater Tubewell is a simple technology for accessing groundwater based on drilling a narrow, shallow well (to a depth less than 20 m), mainly in floodplains with sedimentary formation. A PVC pipe (50 or 63 mm) is installed in the aquifer, and water is pumped using a small 5 to 8 hp pump, which can be powered by gasoline or solar energy. Drilling is carried out using a hand auger or jetting, two inexpensive methods suitable for alluvial, sandy, clay or loamy formation. With a flow rate of 0.5 to 5 m³/hour, this technology provides a reliable water supply for irrigating small farms while limiting costs and technical complexity associated with pumping water from long distances.

Biodiversity: Positive impact on biodiversity

This technology promotes sustainable use of groundwater aquifer for irrigation with less disruption to soils and ecosystems, supports the preservation of natural habitats, and encourages local biological diversity.

Carbon footprint: A bit less carbon released

Using low-energy pumps that can run on solar power, it generates significantly less CO2 emissions than conventional motorized systems that run on fossil fuels.

Environmental health: Greatly improves environmental health

This approach reduces fuel-related pollution, limits deforestation for energy resources, and protects groundwater by ensuring controlled and sustainable extraction.

Soil quality: Improves soil health and fertility

By preventing excessive leaching and allowing for adequate water supply, it helps maintain good soil structure and nutrient richness in agricultural soils.

Water use: Same amount of water used

The technology allows farmers to meet the crop water requirement in the dry season and to mitigate dry spells.

Problem

  • Limited access to shallow aquifers: Tubewell technology is only effective when groundwater is located less than 20 m below the surface, which restricts its use in areas with deep or difficult-to-access aquifers.
  • Geological constraints: Compact or rocky formations are not suitable for tubewell drilling, limiting potential installation sites.
  • Energy and operating costs: Even with small pumps, pumping requires fuel or electricity, which can increase costs for smallholders, especially in remote areas. However, this can be overcome with investment in solar pumps.
  • Maintenance requirements: Pumps and pipes must be maintained regularly; leaks or breakdowns reduce water availability and complicate operation.
  • Initial financial barriers: Although relatively affordable, the initial investment for drilling and equipment can be a barrier without financial support.
  • Variability of water resources: Groundwater availability may vary seasonally or in cases of overexploitation, affecting the reliability of irrigation despite a lifespan of approximately 5 years per unit.

Solution

  • Reliable access to groundwater: Tubewells enable smallholders to tap into shallow groundwater (< 20 m), providing a suitable source of water for irrigation in floodplains.
  • Simple and affordable installation: Drilling with hand augers or jetting makes the technology accessible and inexpensive for small producers.
  • Reduced infrastructure requirements: Water is pumped directly from the aquifer to the plots, limiting the need for water transport infrastructure.
  • Low energy consumption: The use of small pumps (5–8 hp) reduces fuel or electricity requirements.
  • Compatibility with solar energy: Tubewells can be combined with solar pumping, reducing dependence on fossil fuels. Solar  pumps  solutions significantly reduce the energy and maintenance costs associated with water lifting.
  • Simplified maintenance: Equipment is simple and locally available, making maintenance easy for farmers.

Key points to design your project

Tubewell technology offers a simple and economical method for accessing shallow groundwater (< 20 m) in floodplains, enabling reliable irrigation that is suitable for smallholder farmers. It contributes to the goals of agricultural resilience, sustainable water management, and food security in rural areas.

  • Estimating needs and costs: Each well typically irrigates 0.5 to 1 ha, including the pump and drilling tools. Sustainability depends on maintenance and the local availability of materials.
  • Procurement and logistics: Prioritize local procurement of pumps, pipes, and drilling equipment, and plan for transportation and installation in farming communities.
  • Training and support: Train farmers and technicians on site selection, drilling methods, pump installation, and operation, with simple guides and ongoing support.
  • Communication and awareness: Develop guides, videos, and demonstrations to explain the benefits and proper use of tubewells, emphasizing cost savings, year-round irrigation, and solar options.
  • Installation guidelines: Carefully assess the site, choose appropriate sedimentary formations, use the right drilling techniques, and ensure proper casing and gravel packing to guarantee stability and water quality.
  • Complementary practices: Encourage the combination of tubewells with water-efficient irrigation techniques, crop rotations adapted to seasonal recharge, and low-energy pumping systems.
  • Partnerships: Collaborate with local water authorities, NGOs, community groups, and agricultural suppliers to expand installation, provide technical support, and promote maintenance.

By following these recommendations, tubewells enable farmers to access groundwater sustainably, improve productivity, and strengthen agricultural resilience while supporting sustainable water resource management.

Scaling Readiness describes how complete a technology’s development is and its ability to be scaled. It produces a score that measures a technology’s readiness along two axes: the level of maturity of the idea itself, and the level to which the technology has been used so far.

Each axis goes from 0 to 9 where 9 is the “ready-to-scale” status. For each technology profile in the e-catalogs we have documented the scaling readiness status from evidence given by the technology providers. The e-catalogs only showcase technologies for which the scaling readiness score is at least 8 for maturity of the idea and 7 for the level of use.

The graph below represents visually the scaling readiness status for this technology, you can see the label of each level by hovering your mouse cursor on the number.

    1. Assess the site
    Check that the groundwater is shallow (< 20 m) and that the geological formation is suitable, preferably sedimentary soils such as alluvium, sand, clay, or silt.

    2. Choose the drilling method
    Opt for manual auger or jetting depending on the type of soil and the depth of the aquifer. These methods are simple, economical, and suitable for smallholders.

    3. Prepare the equipment
    Gather the necessary equipment: PVC pipes for the well, pipes and hoses for the pump, a 5–8 hp pump, and drilling accessories (rods, bits, or jetting swivels).

    4. Drill the well
    Dig the well until you reach water using the chosen method. Jetting uses water circulation to remove debris, while manual augering requires turning steel rods.

    5. Install the casing
    Lower the slotted PVC pipes into the borehole, add a bed of gravel to filter sediment, then backfill to stabilize the well.

    6. Connect the pump and test
    Attach the pump to the tubewell and test the flow rate by pumping into a container for a set period of time to verify that the water is flowing properly.

    7. Use and maintain
    Before each use, check the pump's fuel and oil. Avoid air bubbles during pumping and keep the well protected by closing it after use to prevent contamination.
