Design and Development of a Manual PVC Pressure Water Pump for Lake Water without Electricity

Abstract

In rural and remote areas, access to water without electricity is a critical issue. This paper presents the design and fabrication of
a manual PVC water pump which works on the principle of piston-cylinder arrangement with flap-type non-return valves. The system
uses PVC pipe, elbows, T-joints, cocks, and rubber seals for cost-effective construction. The pump operates manually, creating suction
and pressure for continuous water flow from a lake or pond without the need for electricity. Experimental trials indicate that the pump
can lift water up to 1.5–2 meters with an average discharge of 4–6 liters per minute, making it suitable for domestic and small-scale
irrigation applications. The design is simple, portable, low-cost, and can be fabricated using locally available materials.
