2 Proposal On INSTALLATION OF HYDRAULIC RAM PUMP At Singati, Dolakha, Nepal

3 1.1 Background 1. INTRODUCTION Singati lies in mountainous district Dolakha of Janakpur Zone which is situated in the central Development Region of Nepal. With total land area of 2191 sq. km, Dolakha shared its border with Solukhumbu and Ramaechhap to the east, Ramechhap and Sindhupalchowk to the south, Sindhupalchowk to the west and Tibet to the north. Singati bazar lies at the distance of approximately 180 km from Kathmandu and about 33 km east from main Dolakha bazar. This is located in confluence between Singati River and Tamakoshi River, which is main market center of north-east part of Dolakha district. This market is also route to trek Mt. GauriShanker and TshoRolpa Glacier Lake. Figure: Map of Dolkha district

4 1.2 Problem Singati is the remote village with the around 50 households (we are planning our project for 10 households). There the people are facing the problem of proper water supply. Since the place is not connected to the National Electricity Grid and micro-hydropower being the only source of the energy, the people there can t pump the water from the river flowing nearby. The Nepalipaper industry (a cottage industry) there is also facing the problem of proper water supply. In the scenario the people there need a device which will pump water without the electricity. So, we intend to install a Hydraulic ram pump and make a reservoir at the supply so that the people residing there will be benefitted. 2. DISCUSSION 2.1 Literature Review The automatic hydraulic ram is a pumping device that has been widely used for nearly a century in the rural areas, for lifting water to the certain heights. It is an ideal machine for water pumping if certain conditions are satisfied, because it works solely on the power from falling water carried in a pipe from a spring steam or river without any need for an additional power source. Rams can be used to water livestock, supply water for homes and communities and even for small scale irrigation. The amount of water delivered and the height of delivery depends on the water source and the terrain. For practical planning purposes the delivery head is typically no more than 10 times the drive head although water can be pumped higher in some situations. The basic parts of the hydraulic ramp pump system are: A water source and supply pipe Body of water which may be the source itself to supply the drive pipe. A drive tank or standpipe can be used also The drive pipe, typically of galvanized steel but for low performance pumps, PVC can be used The pump itself A delivery pipe or hose to the point of use

6 2.2 Working Principle The energy required to make a Ram lift water to a higher elevation comes from water falling downhill due to gravity. As in all other water powered devices, but unlike a water wheel or turbine, the ram uses the inertia of moving part rather than water pressure and operates in a cycle based on the following sequences. Sequence I Water from the source flow through the drive pipe (A) into the ram pump body, fills it and begins to exit through the waste or impulse valve (B). The check valve (C) remains in its normal closed positions by both the attached spring and water pressure in the tank (D) and the delivery pipe (E) (no water in the tank prior to start up). At this starting point there is no pressure in tank (D) and no water is being delivered through exit pipe (E) to the holding tank destination. See Figure below. Sequence II Water entering the pump through the drive pipe (A) has its velocity and pressure being directed out of waste valve (B) as illustrated in Figure below.

7 Sequence III Water has stopped flowing through the drive pipe (A) as a shock wave created by the water hammer travels back up the drive pipe to the settling tank. The waste valve (B) is closed. Air volume in the pressure tank (D) continues expanding to equalize pressure, pushing a small amount of water out of the delivery pipe (E). See the illustration in Figure below. Sequence IV The shock wave reaches the holding tank causing a gasp for water in the drive pipe (A). The waste valve (B) opens and the water in the drive pipe (A) flows into the pump and out of the waste valve (B). The check valve (C) remains closed until the air volume in the pressure tank (D) has stabilized and water has stopped flowing out of the delivery pipe (E). At this point sequence 1 begins all over again.

10 S. No. Institution Funding Amount [USD] 1 Community Education Pilot Project, KU 50 - Transportation 2 Kathmandu University 50 - Workshop facility, Department of Mechanical Engineering 3 Local Community 30 - Workers and helpers 4 Program Amount form Total Community Participation in the Project Without complete community involvement, even a water supply system that is technically perfect is likely to encounter serious problems and may fail altogether. So for the successful completion of the project the involvement of the community is must. During the installation phase of the project the labor donation will be provided by the community. The idea beside the matching fund collected from the villagers is to ensure the community involvement for the sustainable use of the project. A small user group can be formed for the proper maintenance of the hydraulic ramp pump. 2.8 Expected Outcome After the successful completion of the project, we hope the expected households to be provided with the water supply facility. We expect the involvement of the community members for the smooth operation of the project. The successful completion of the project will be the motivation for us to extend the same project to the larger group of people.
