This paper provides an overview of the ancient evolution, design and development of different types of spiral tube water wheel pumping system (STWWPS). It has always been a challenge to lift water and carry it to some other location for executing meaningful work, making use of the alternative sources of power. Several kinds of non-conventional energy sources and techniques have been tried. Each one is having its own merits and demerits. Making use of the kinetic energy of lowing water can be achieved through different kinds of water wheel. Spiral tube powered by kinetic energy of lowing water has been utilized for lifting and carrying water for irrigation and other purposes, contributing to the replacement of conventional diesel and electric power sources. These conventional sources are expensive (Diesel) and often unreliable in rural areas (Electricity). This review paper examines the design, development, and performance evaluation of various spiral tube pumping systems, including single, double, multilayer, pedal type, four scoop type, and multi-purpose models. It examines the load torque, power, ef iciency, and stress analysis of shaft and bearing, and the impact of rotational speed, submerged ratio, and number of spiral pipes on the performance of the pumping system. The working principle allows these pumps to create a column of water within its coil that alternatively the air which is compressed as it moves towards the center of wheel. These pumps not only save electricity and diesel cost but the maintenance cost is also low apart from contributing to the clean environment.

In the early 19th century, it was used extensively as a boiler feed water pump. Nowadays, it is used for pumping highly viscous fluids such as concrete, heavy oils etc. Normally it has relatively small capacities and large delivery head and is used in applications where low discharge is required at high pressure. In this project, a weighted object acts as a pendulum which conserves momentum and swings with the application of human effort. It gives rotational motion to the shaft and the rear sprocket attached with it, which rotates the crank disc which in turn reciprocates the plunger. Because of that water is sucked in one stroke into the cylinder and is delivered out from the cylinder in the successive stroke. The development for this project was prompted due to the need for pumping systems that do not use electricity as its power source in underdeveloped remote areas.

The evolution of the major achievements in water lifting devices with emphasis on the major technologies over the centuries is presented and discussed. Valuable insights into ancient water lifting technologies with their apparent characteristics of durability, adaptability, and sustainability are provided. A comparison of the relevant technological developments in several early civilizations is carried out. These technologies are the underpinning of modern achievements in water engineering.

Hydraulic ram pump is an automatic water-pumping equipment generally used to pump drinking and irrigation water in mountainous and rural areas having short of power. In the past, it has been analysed and optimized by fabricating various prototypes and conducting experiments and comparisons. In general hydraulic pump lifts water by using electricity, fuel or manpower. There are many technologies to lift water without using electricity. As fossil fuel one of the most energy crises in the world , it is necessary to use the fuel wisely.It is Simple in construction and its reliable giving a low maintenance requirement. It is Automatic, continuous operation requires therefore no supervision or human input. Use of a renewable energy source ensuring low running cost. Experiment was carried out for the air vessel of 52cm and 22cm and comparisons were conducted with other products. The results how the outlet discharge rate and wastage rate would be affect by the difference in the length of the air vessel.

The arrangements for small-scale irrigation requires a significant attention in the agriculture of rural areas of developing countries. The pressure on water resources has increased in last few decades, causing the lowering down of the water table and making the manual equipment impractical for the extraction of water. Shadouf is still in operation in most of the rural parts of Nigeria and is used for lifting the water by distributing the force applied by the operator. Shadouf deliver the water with low efficiency, have shorter operational life, and its efficiency primarily depends upon the force applied by the operator. For the efficient irrigation, improved equipment is required which can lift the water from greater depths with a better efficiency. In this study, the working methodology of shadouf is reviewed and a modified water lifting devices was designed which can lift the water from greater depth (more than 6 m). The experimental results indicate the improved efficiency with the use of modified water lifting device. The comparison of conventional shadouf and modified lifting devices shows the increase in efficiency by 16%. The efficiency was identified at the variable head and seasons. Such low-cost devices are expected to be extremely useful to the farmers around the world, especially those with small agricultural fields and situated in regions with low rainfall.

A pump is a device that can be used to raise or transfer fluids (Rony et al., 2015). Pumps are selected for processes not only to raise and transfer fluids from one point to another, but also to meet some other criterion. The various water pumping systems available require sufficiently large effort of about 36Jouls depending on the manufacturer to be operated and an average person can use these pumps continuously only for a short time. The ever increasing demand for energy has led to the formation of various advanced resources which produces a certain part of the required energy. One principal consumer of a large amount of energy is our household itself which is wasted in pumping water, irrigation purposes, etc. (Rony et al, 2015). It is in this context the importance of pendulum pump arises, by the use of which a large amount of energy can be conserved. However the modified hand water pump with a pendulum only requires a minimum effort of about 13.7jouls to oscillate the pendulum and maintain these oscillations of 45strokes per minute. The pendulum water pump is essentially developed for rural communities where there exist no electricity and the other means of pumping water are practically expensive for the people in the community however, further research as far as improving the operation and performance of the pumping system must be emphasized such that agriculture production is improved as well has applying the technology in other fields.

Based on previous studies, a low-speed water pump was developed, and assessed through a river flow test. The designed water pump consists of 5 wheels, 2 pistons, and 1 valve. The 5 wheels are arranged in the same axis and chain. The first axis consists of the 1 st and 2 nd wheels, namely, 1. The 2 nd wheel is connected in the same chain, with the 3 rd in parallel zone as the 4 th , 2. The 4 th is connected to the same chain as the 5 th wheel, namely 3. Furthermore, the 4th wheel is arranged in the same axis with the piston activator. In the pump system, there are 2 pistons for triggering the lifter, from the lower to the higher position. The size and dimension of the whole component used in the pump system, are developed from the previous computational studies. The testing of the converter and pump system performance, has been carried out based on the water flow condition (v), radial speed of wheels (1, 2, 3), water lift height (h), and discharge of pumped water (q).
