Hydram: A Solution to Livelihood Enhancement - Centre for Rural Technology, Nepal

  1. 1. CRT/N e-news, February 2012 Vol. 2 No. 18 1BackgroundTwo-thirds of Nepals total population belongs tothe hilly region in Nepal and their settlements areusually remote and sparse. Such settlements cannot beeasily served with conventional piped water systems.The installation, fuel and maintenance of conventionalpumping systems using fossil fuel (diesel or gasoline) orother forms of energy such as electrical or solar drivenpumps are usually unaffordable for poor, remotecommunities. In this context, rural people, especiallywomen and children, have to walk for hours to distantsprings for collecting water for household purposes. Inaddition, managing water for irrigation purpose is still abig challenge.Hydram as a SolutionThe Hydraulic Ram Pump (Hydram) is a maturetechnology existing since 18th century. It uses thepower available in flowing water, dropped from heightof few meters, to lift certain volume of the water tomuch greater height. As the technology only uses thepower of flowing water resource that is free, itsoperating costs is very low. Moreover, Hydram canalso be considered as a zero emission technology.With the advancement in the design, the technologycan be manufactured in the country, easily operatedand maintained by the rural communities. The systemmay cost over USD 5000 depending upon size andcapacity of the system.In developing countries, the Hydram is typically used todeliver water for household use (drinking andsanitation) in rural communities where people have tocollect and carry water manually from a distant source.It is also used for small and medium scale irrigation inmany developing countries. This system can alsosupport other income generating activities such ascattle rearing, fish farming and bio-fertilizer production.Centre for Rural Technology, Nepal (CRT/N) hasadopted an appropriate hydraulic ram pump systembased on the patented technology of AlternativeIndigenous Development Foundation, Inc. (AIDFI), thePhilippines. AIDFI has eight different designs of rampump of various sizes and intake rates (10 to 1300 litresper minute) that are suitable for different heads, flowrates and delivery heights. Usually, for small schemes,an individual pump is installed but for larger schemesmultiple pumps are connected in parallel or in seriesdepending on the head and flow rate. The pump canoperate continuously lifting water up to 200 metreshigh and delivering water in a reservoir at the village,which normally will be filled up overnight and used upthroughout the day.Hydram as Irrigation TechnologyWater pumped by Hydram is used for householdpurpose including sanitation and irrigation. Generally,water supplied by the system is used in micro-irrigationespecially for vegetable farming. The Hydram canoperate even during the dry months supplying waterfor vegetable crops. This serves to be additional yieldand income for the farmers compared to their usualharvest. Further, the Hydram can also be used tosupplement rice and cereal cultivation during erratic orinsufficient rains. This will help the farmers adapt to thechanging climate and allow more reliable returns.Access to water can boost economic development inthe community and also support livelihooddevelopment, such as brick making or types of agro-processing.One Hydram of 4 inch can irrigate approximately 20ropanies (approx. 1 hectare) of land. A single Hydramcan pump approximately 28,000 to 250,000 litres ofwater per day. Over a 110 day crop growing period,the system can deliver an estimated irrigation wateramount of nearly 300 mm (or about 3 mm per day) tothe 20 ropanies of land.CRT/Ne-newsCentre for Rural Technology, NepalTowards Action for Development… Since 1989 February 2012, Vol. 2 No. 18Hydram a Solution to Livelihood Enhancement
  2. 2. CRT/N e-news, February 2012 Vol. 2 No. 18 2Hydram as a Solution to Gender NeedsNepalese society perceives water fetching activity asmainly womens responsibility. Household works aretraditionally on the shoulder of women and caring offamily is a household domain, which is where womenmean to confine their works. "Water and energy… areactivities that take up an enormous amount of women’stime and pose a major bottleneck to their productivityas well as their contribution to society as care providers.By addressing these bottlenecks, women can bringabout improvements in all-round quality of life for theirhousehold and themselves. It can help them meet thepractical needs (ensuring daily survival) of the womenand also addressed their productive needs (incomegeneration and increased economic capabilities), aswell as their strategic needs (position in society, inparticular to gain greater equality with men, and helptoward their empowerment)." (Women, Energy andWater in the Himalayas, UNEP/ICIMOD) This saving intime must be harnessed by integrating other supportmechanisms (such as credit mobilization, skilldevelopment training, and institutional developmenttraining). Uplifting of water saves many hours whichreduces drudgery and the time spent collecting water.This, in return, can allow more time for children tostudy, and adults to spend on livelihoods or social time.Author: Dinesh Adhikari, EngineerContact: dinesh@crtnepal.org(This article may not necessarily reflect views of CRT/N.)Improved Water Mill (IWM)The Improved Water Mill (IWM) is a modified version oftraditional water mill. IWM is an intermediatetechnology that increases the efficiency of thetraditional water mill resulting in increased energyoutput thus helping both the millers and its users. Theimprovement covers basically the replacement ofwooden parts (rotor, shaft and chute) with metallicparts. This increases its operational efficiency as well asmakes it more useful with additional machines forhulling, oil expelling, saw milling, lokta beating, andelectricity generation. The chute is mostly wooden,however, sometimes is made of polyethylene or tinsheet.The speed of IWM shaft ranges around 200-300 rpmdepending upon the head and flow of water and thepower output ranges from 0.5 kW to 3 kW. Its grindingcapacity ranges from 20-50 kg/hr (maize) while thetraditional mill only grinds 10-20 kg of maize per hour.The repair/maintenance cost is reduced afterinstallation of IWM and its life span can be maximizedup to 10 years.The IWM exists in short shaft (SS) and long shaft (LS)versions. The selection of whether to install a SS or LSalso depends on availability of water power. The lengthof a SS is 4ft whereas that of LS is 6ft. A SS IWM is usedfor grinding only while a LS IWM has diverse end-usesof its power. Having a longer shaft, the LS IWM can runa number of machineries transferring its power throughsuitable couplings. Thus LS IWM has great versatility inits final delivery of services. Though the installation costincreases, a LS IWM provides opportunity for theinvestors to diversify their business.TechnologySketch of an Improved Water MillWomen Carrying Water to Meet Their Practical Needs
  3. 3. CRT/N e-news, February 2012 Vol. 2 No. 18 3Solar Dryer ProjectThe Solar Dryer Project under the title "Women inDrying Food and Heating Water Using Solar Dryer" isundertaken by Centre for Rural Technology Nepal(CRT/N) since October 1, 2010 with support form TheLemelson Foundation, USA. The project has a target todisseminate 75 units of cabinet type solar dryer amongthe rural women in suburbs of Kathmandu with supportfrom Women Support Cooperative (WSC).Participatory Assessment ReportCRT/N has conducted "Participatory Assessment" onthe impact of the cabinet solar dryer. The majorobjective of the assessment is to get comprehensiveand integrated understanding of the project,stakeholders involved and project implementation. Theassessment methodology followed data collection toolssuch as semi-structured interview, phone interview,field visit, observation, focus group discussion.Based on qualitative and quantitative analysis, theassessment concluded that behavioral change in usingsolar dryer for heating water and drying food is seenamong technology users. The report also depicts thatthe users benefited from the technology especially forhousehold purpose. Moreover, the technology provedeven more beneficial for those who took up homebusiness from solar dryer. It was found that the dryersare being used for drying variety of food items such as,meat, pulse nuggets, radish, spices, fruits and nuts,cereal, bread crumbs, etc. The users are also utilizingdryer to heat water which is used in making tea,washing and bathing.The project has been successful in disseminating 75solar dryers to WSC members. The reasons of successin meeting physical target of the project as highlightedby the report are credit support from WSC and subsidydelivery from Alternative Energy Promotion Centre(AEPC). These approaches have made the solar dryersaffordable to the users.Excerpt from Final Report: Gender Issues in Renewable (Rural) Energy Policies of Nepal, February 2011, CRT/N andIAPH Forum with support from ENERGIA: International Network on Gender and Sustainable Energy, the Netherlands.Following analysis has been extracted here to highlight to what extent Subsidy Policy 2009 has addressed genderconcerns. - EditorsThe subsidy policy has been formulated with the objective of enabling to rural poor and socially disadvantagedpeople to access improved energy services. The Policy makes direct provisions for micro hydro, solar (home systems,dryer, PV pumping and cookers), metal cook-stoves, biogas and wind technologies. Largely, the subsidies are decidedbased on end use, sector (domestic, institutional and community) and geographical location. However, in case ofbiogas programme additional subsidy has been announced for the “Poor, Dalit, Depressed, Conflict Affected” whichincludes the poor women member group of the rural development banks.The Subsidy Policy 2009 has been analyzed from gender perspective. The gender gaps identified from analysis arepresented in the Table 3.5 below.Project FeatureInterview with Solar Dryer UsersGender Mainstreaming in Energy
