Hand-Powered Rice Irrigation : DIY Piston Pump in Action

A Little Wisdom Helps You Become Smarter !

In the video, a farmer demonstrates a manual irrigation tool designed for small-scale rice farming. Seated on a wooden stump, he operates a hand-powered piston pump attached to a tilted PVC pipe supported by a Y-shaped wooden frame. With each pull and push of the lever, water is drawn from a nearby source into the pipe and directed toward the fields.

This tool, a hand-operated piston pump, consists of three key parts:

A PVC pipe angled by the wooden frame to guide water flow.

A piston mechanism (similar to a bicycle pump) with two one-way valves.

A lever for manual operation.

How it works:

When the farmer pulls the lever up, the piston creates suction, opening the lower valve to draw water into the pump.

As he pushes the lever down, the lower valve closes, and the upper valve opens, forcing water into the tilted pipe. Gravity then carries the water to the fields.

This low-cost, zero-energy tool relies on simple physics—pressure difference and one-way valves—to lift water efficiently. Its design uses locally available materials (wood, PVC, basic valves), making it accessible for farmers in remote areas. Unlike electric pumps, it requires no fuel or maintenance beyond occasional valve checks.

Ideal for small plots, this method combines traditional farming ingenuity with practical engineering, proving that sustainable solutions can be both simple and effective.
