Farmpond : cost breakdown

Introduction: 

Generally farm pond are constructed in a 5-10% of total farm area, for the purpose of water storage, irrigation, livestock, fisheries, ground water recharge, usage in dry season etc. A medium sized farm pond unlined pond (roughly 20m×15m×5m) costs around ₹80,000-₹1,50,000 in India. If a plastic or HDPE geomembrane lining is required for sandy soil, or for larger commercial setups, total costs can range from ₹1.5 lakh to over ₹2.5 lakh without subsidies.

How do you construct a farm pond?

Step-1: mark and clear the site 
Mark the pond boundary with stakes and string. Clear all vegetation, topsoil, and roots from the area. This process includes labour charges which range from 500 to 1000 per day, 1 male labour for marking(~ ₹800), 2 female labour for weeding (~₹1200). Total costing around ₹2000 to ₹3000.
Step-2: excavation
JCB (backhoe) excavation: ₹3,500–5,000 per hour. A 20m × 15m × 2.5m pond requires approximately 750 cubic metres of excavation — typically 8–12 JCB hours (₹35,000–60,000).
Excavated soil goes to:
Building up the embankments (berms) around the pond — compact well.
Filling low spots elsewhere on the farm.
Building raised beds if the soil quality is good.
Step-3: compacting and shaping 
Use the JCB bucket to compact the pond walls and bottom to 1.5:1 slope (1.5 horizontal for every 1 vertical) — stable slope for clay soil. Steeper slopes erode.
Step-4: lining(of sandy soil) 
Sandy or gravelly soil requires an impermeable liner:
Clay lining: Source 15–20 cm thick layer of clay; spread and compact — ₹20,000–50,000 for material and labour
HDPE geomembrane liner: 0.5mm or 0.75mm HDPE sheet; most reliable — ₹40,000–80,000 for a medium pond.
Step-5: Spillway construction
A spillway prevents the embankment from breaching during overflow:
Cut a notch in the embankment 30–50 cm below the top
Line the notch with rocks or concrete to prevent erosion
Direct overflow to a drainage channel leading away from the pond
Step-6: Embankment stabilisation 
Plant grass (vetiver is best — deep roots) on embankments immediately after construction. Bare earth embankments erode rapidly in monsoon.
Step-7: Pump installation Install 
A submersible pump at the bottom of the pond connected to the farm’s irrigation mainline. Enclose the pump electrical connection in weatherproof housing.

Government Assistance and Subsidy

Farm pond subsidies cannot be assumed to be the same across India. They depend on the state, scheme, farmer category, pond size and the components covered.
For example, the Telangana government district horticulture page currently lists 50% assistance for a specified 20 × 20 × 3 m farm-pond programme, while PMKSY's Per Drop More Crop guidelines specify a 50% cost norm for certain individual water-harvesting systems, subject to maximum limits and other conditions.

Conclusion: 

The cost of constructing a farm pond depends on much more than its dimensions. Excavation, lining, embankment construction, inlet and silt-trap structures, spillway, pumping equipment, labour and fencing can all contribute to the final investment.
For a farmer, the most economical pond is therefore not necessarily the cheapest pond to construct. It is the pond that provides adequate storage, minimizes seepage, can be filled from available runoff and supplies water efficiently to the crops.
A technically designed farm pond, combined with efficient irrigation such as drip or sprinkler systems, can turn a one-time water-harvesting investment into a long-term asset for improving water security, cropping intensity and farm resilience. PMKSY itself emphasizes expanding access to water on farms and improving on-farm water-use efficiency.
