We then had to chose our design solution from the 20 potential ideas that we have contemplated. We first chose our 5 most desirable design solution and placed them in a decision matrix.
The 5 design solutions were:
- Gravel ditch: periodic ditches in the gravel road to control water run-off
- Self-serve vehicle wash bay: to prevent vehicles from spreading weeds
- Community/evacuation centre: Multipurpose building to serve as haven for community and for storage of cultural artefacts
- Riverside embankment: prevent gully erosion from contaminating river system
- Water filtration system: purification of water from bores.
The decision matrix used the following criteria:
- Cultural appropriateness,
- Economic impact,
- Environmental impact,
- Ethical suitability,
- Social suitability and
- Sustainability of the design.
These considerations are discussed further here.
As the water filtration system had the highest rating, it became our design solution.
