engineers without borders challenge 2012-2013 habitat for humanity vietnam. WATER AND SANITATION
aims- the 2012-2013 EWB Challenge provides an an exciting opportunity to develop inovative and appropriate project solutions that can make a real contribution towards the sustainable development of the Anh district within the Kien Giang province on the Mekong Delta.

challenge- you must read the engineers without borders 2012-2013 challenge carefully. Tthis is available on the EWB Australia (http://www.ewb.org.au/explore/initiatives/ewbchallenge/hfhewbchallenge) or http://www.ewb-uk.org/ewbchallenge.

design theme- water and sanitation.

key design considerations- 1. aligns with habitats goals and values 2. design should be innovative, low cost, smal-scale, affordable and appropriate 3. design should take into account culturural customs local norms and religion 4. proposed solution must be sustainable through considering the way that local matrials, skills and knowledge ofthe local community are used 5. design should be durable and take into account the natural enviroment, including disasters and climate change and sustainable land management.

Design Projects
EWB and Habitat for Humanity invite you to consider one or more of the following design projects:

?Develop a simple and affordable water purification system to remove contaminants such as bacteria, chemicals, pesticides, heavy metals and salt from the surface or borehole well water in the Mekong Delta region to procure drinking water.
?A method for storing and filtering rainwater. Currently, rainwater is stored for months in ceramic/cement jars and impurities build up.
?A low-cost, environmentally friendly toilet and sewerage treatment system suitable for a typical household in the Mekong Delta and taking into consideration the rising water levels in the Mekong delta.
?Household hygiene practices in the Mekong Delta are poor due to little education around sanitation practices and maintenance of sanitation equipment. Develop a training system that can be used as part of Habitat Vietnam current activities to increase communities? capacity in this area.

Design Considerations
When designing a solution, the following issues have been identified and should be considered a priority. The proposal should consider:

?The effect that any chemicals used will have on the environment.
?Cultural beliefs and practices of the people living in the community.
?Cost associated with implementing any proposal.
?Infrastructure already in place for water and sanitation.
?Appropriateness to the local environment. Tidal fluctuations and rising water levels should
