Improving Quality of WASH Data Collection to Inform Project Operations in CE

The link between improved sanitation systems and human health has been well established. In a Cambodian context, lack of effective sanitation systems and poor hygiene practice result in an estimated 10,000 deaths annually.This research identified and classified the issues being faced by NGOs collecting data in Cambodia. The two most prevalent were communication issues, relating to qualitative processes, and poor practice, arising from the collection of quantitative information.

Feasibility of Biodigesters for use in rural Papua New Guinea

The research goal is to develop a framework to assess “if the ATEC M3 biodigester is suitable to dry cocoa beans in Papua New Guinea.” Biodigesters offer a renewable energy source, valuable organic matter and can be used to provide access to sanitation or organic waste disposal facilities. The framework was applied to the Papua New Guinea case study to determine the potential for biodigesters to dry cocoa beans. Key results from the framework indicate that rural users would be able to operate the biodigester optimally and autonomously pending some conditional statements.

The design of a low cost solar-powered water pump for Koh Dambang

Solar-powered water pumps can be used for irrigation or to meet the personal water demands of remote populations. The proposed system for personalwater pumping was estimated to cost around$560. After consulting with Cambodian Rural Development Teamit was found that some households might even be able to afford the proposed system without having to share it. This has provided an indication that the system is sufficiently low in cost. It would also mean that the roughly 2 cubic metres of water it supplies per day could also be used for irrigating subsistence crops.

Passive energy concepts for heating, cooling, and ventilating in the lower Himal

Passive energy concepts are extremely important in the context of developing countries, as they provide a means of maintaining thermal comfort in buildings, by applying simple design principles, without the use of electricity. This paper presents the various passive energy concepts that are suitable for the context and makes recommendations as to the most appropriate options for each climate. Shading, ventilation, building orientation and shape, thermal mass, insulation, and window placement were found to have the highest potential impact on thermal comfort, and should therefore be integrated into building design. Further investigation will need to be undertaken to determine how to best adapt these solutions into an earthquake-proof design.

Energy Efficient Refrigeration for Low-Income Communities in Cambodia

Communities in rural areas of Cambodia currently do not have access to mains electricity, and instead utilise car batteries for their electricity needs. Refrigerators are a staple in western society, however use a lot of power which can keep them out of reach from Cambodians to take advantage of. The aim of this thesis was to improve the efficiency of a refrigerator so that it could be feasibly run from a car battery and solar panel while staying below 3.8°C in a 24-hour period.

The impacts of non-arsenic pollutants on the effectiveness of arsenic removal

Arsenic contamination in Cambodian groundwater presents an urgent safety hazard. The use of iron-oxide coated sand (IOCS) was found to be an economically feasible and effective adsorbent for arsenic removal. The findings reinforce the effectiveness of IOCS for arsenic removal and pave the way for research into a low cost and efficient arsenic removal strategy tailored to Cambodian water conditions.

Harvesting wind energy using fluid-elastic flutter

This research aimed to address the need for asimple, low-costelectricity source inremote communities. A fully-passive flapping foil turbine was chosen as the electrical generator due to it meeting the requirements set out. Using Computational Fluid Dynamic (CFD) software, different turbine design parameters were tested with optimising power output as the prime objective. Basic trends of increasing energy harvesting potential were found, but no definitive results were obtained due to time constraints in the research project. Areas for improvement and further development have been determined.

Formulation of a performance model to aid design of spiral pumps

Several options for low cost water pumping were explored and it was determined that a spiral water pump design is a promising option for contexts such as this. Spiral pumps have a simple design and can be made from locally available materials. A major challenge of installing spiral pumps is in determining the required size of components to meet certain flow rate and elevation needs. To help design and optimise spiral pumps an analytical model was produced

Understanding the seismic behaviour of free-standing gabion walls

Nepal is located in one of the most seismically active regions in the world and remains vulnerable to catastrophic disaster due to local and traditionally built structures being inadequate to withstanding high magnitude earthquakes. Using gabions to construct houses is still highly experimental, and though its use in Nepal could be advantageous due to it being low-cost, environmentally durable and requiring low skill to construct; it is hard to determine whether this alternative construction method is feasible in such seismic regions as there is a clear lack of literature surrounding the seismic behaviour of gabion walls let alone gabion houses. Through the completion of this research, recommendations and comments on the appropriateness of using gabions for earthquake proof construction in Nepal will be given; for in hope that one day it could improve earthquake proof design and construction as well as preserve life.
