Machine generated alternative text: School of Civil and Environmental Engineering Objectives More than ever, engineers are turning their attention to areas in the world where the need is greatest. This project will allow you to learn from those who have taken their engineering skills to developing regions, and to work on the Engineers without Borders (EWB) Challenge for 2018. You will learn about the social, cultural, global and environmental responsibilities of engineering. Design Task Summary Engineers Without Borders (EWB) is a community organisation aimed at creating social value through engineering. The EWB Challenge is a design program aimed at developing innovative, creative solutions to sustainable development issues identified by EWB and a community-based partner organisation. The 2018 EWB challenge partner is the Cambodian Rural Development Team (CRDT), working with communities communities and the environment through community development and natural resource management proje (EWB, 2018). The CRDT is working with communities in Ksach Leav, Koh Khnear, and Puntha Chea along the Mekong River. There are a number of challenges facing these communities. Most families grow rice on small plots of land adjacent to the villages and away from the river, and rely on rainfall to irrigate these plots. However, rainfall patterns have been noticeably varied in recent years affecting rice agriculture and impacting household water sources. While rainwater collection is more stable for household use during the wet season, other sources (such as river water) must be used during the dry season. There is currently inadequate access to an electricity grid, although some families have solar panels, generators and batteries. The cost makes solar panels inaccessible to many families.

Machine generated alternative text: Engineers without Borders (EWB) has partnered with CRDT to provide engineering and design solutions for projects identified for the communities of Kratie Province. The designs and innovations that result from the EWB Challenge in 2018 will make a direct contribution towards CRDTs work within Cambodia. Your task will be to design and build a rainwater capture and reuse system that could be adopted on a house in the villages in Kratie Province. The system should: Capture rainfall runoff; Have a first flush system to prevent contamination; and Consider the easy and safe reuse of the water within a house for a variety of uses Mains electricity is unavailable, so a mechanical or human powered system is required. Solar powered options may also be considered. You will need to consider water quality and quantity and how the water can be used within the house or other parts of the community. Your design must consider how the water availability could be stretched during periods where rainfall is inconsistent. The design should be simple and effort should be made to use locally available materials. Project Lectures A series of lectures will be given to complement the project as outlined in Table 1. You will need to attend all lectures. Table 1: Lecture template for the project Project-specific lectures Lectures in common with all Projects offered by the School of Civil and Environmental Engineering Introduction to the project and Cambodia Principles of Humanitarian Engineering Water and sanitation options for developing regions Teamwork & Technical Report Writing Engineering drawing (CAD). Sustainable design and construction technologies and practices. Societal and environmental ethics Design Specifics Your design team is to provide advice on the most suitable water, wastewater and sanitation engineering works to assist the sustainable development of the community. Design solutions should be consistent with the information provided in lectures regarding the local culture and context. Your project will involve the following stages: Calculate the quantity and quality of water to be captured Consider the opportunities and constraints for possible designs Design a system that can: a. Capture and store water b. Divert contaminated water with a first-flush device c. Considers options for the reuse of the water within a house Recommend how the system should be maintained to ensure future sustainability Remember: BE CREATIVE! THERE IS NO RIGHT ANSWER! Rainwater collection in Kratie (EWB, 2018)
Machine generated alternative text: Deliverables At the conclusion of the course, you will submit a written report and a working model of your rainwater collection system. Deliverable 1: The Written Report. The report should include details on: Identification of alternative options and the justification used in the selection of your final design; Details of the chosen design; Description of how your design is appropriate to the social, environmental, economic and technical context; Cost of construction and operation and economic benefits Discussion of the long-term sustainability and maintenance of your design, including options for ensuring this; Advice on the role of the community in the construction and operation of your design; Deliverable 2: Working model of the Rainwater Collection and Reuse System You are required to develop a concept plan, schematic and physical (i.e. working) model for the rainwater collection system. On the day of testing, you will present the rationale for your chosen design and then demonstrate whether it is capable of meeting the criteria specified during the lectures. The winning design will be evaluated in regards not only to performance, but also expected reliability, ease of construction and maintenance, anticipated cost, and quality of construction. Designs that fulfil all criteria will be viewed favourably. Marking Criteria The Final Report will be marked according to the following criteria: 1. Process how was the final design reached; alternatives considered and justification of final decision. 2. The Design Solution creativity and sound use of engineering principles; effective and efficient solution to the problem. Calculations to support the chosen layout and solutions are required. 3. CAD Drawings plan and cross section drawing in CAD showing the details of your final design 4. Design Sustainability and Ethical Responsibility demonstrated understanding of the social, cultural, environmental and economic context of the project; clearly communicated principles of sustainable design; community involvement and benefit. 5. Cost and economic benefits what is the cost including initial costs, operation and maintence? 6. Communication logical report format; grammar; correct referencing; use of tables and figures; clear executive summary. The Working Model will be marked according to the following criteria: 1. Five minute verbal explanation of the design; 2. Quality, novelty and innovation of the design and construction; 3. Capacity to capture, divert and reuse water. 4. Cost of materials Date of Completion The Draft Report is due Monday, Week 7. The Final Report and Model are due Monday, Week 11.
