From idea to reality
• Motivation for changing status
• Clarification of relevant stakeholders
• Listing of assessments criteria
• On-site analysis
• Posing alternative sanitation systems
• Evaluation of the systems and determining order of priority
• Selection of solution
• Design and implementation
• Organisation of use and operation
• Evaluation, control and follow-up
ON-SITE ANALYSIS
Environmental analysis
 The physical conditions and sensitivity of the local environment
Stakeholder analysis
 Identification of stakeholders
 Interaction between stakeholders
 The attitudes and preferences of the stakeholders
Criteria for assessment
• Economy – construction and running cost, expected lifetime
• Hygiene and safety – public health, working environment
• Operation and maintenance
• User aspects – shelter, odour, comfort, use, cleaning
• Self-management/administration – visibility of local material
recirculation, understanding and influence on decisions, installation and
running
• Robustness – adaptability to new users and new demands
• Demonstration value – testing and presentation of new technologies,
spreading of knowledge
• Load on the environment – resource (energy, land, water, materials)
consumption, pollution: impact on water, soil and air.
General priority of assessment criteria
for the four projects
• Economy
• Hygiene, health and safety
• User aspects – shelter
from weather
from animals
from other people
– order
keeps all human waste in one place
– odour, comfort
• Self-management/administration
– local material recirculation
