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.

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!

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

cultural, environmental and economic context of the project; clearly communicated principles of 
sustainable design; community involvement and benefit. 
5.
 
Cost and economic benefits
