For an AguaClara water Treatment plant there are both technical and social requirements that need to be met in order to ensure its proper functioning and sustainability. The technical requirements ensure that water treatment is necessary, that there is sufficient water, and that after treatment it will be potable. The social aspects look to ensure that the community is interested in this technology as well as organized and committed to the project.

Technical Requirements

• Water source is a surface water or a ground water that is under the influence of surface water.
• Flow rate requirement between 6 and less than 100 L/s (in Honduras this corresponds to a population size of between 1500 and less than 30,000 people). Note that we are working to extend this flow rate range in both directions to accommodate a wider range of community sizes.
• Water source with turbidity frequently above 5 NTUWater quality issues limited to turbidity and pathogens, pathogens, and dissolved organic matter.
• Ideally the water supply network is designed such that a single water treatment plant can serve the entire community. Neighborhood taps or kiosk operation has not yet been tested.
• Ideally the water source is at a higher elevation than the community. In this case the entire system can be designed to be powered by gravity. If the water source is not at a high enough elevation then pumping must be included and the maintenance costs will be higher. AguaClara does not currently provide design guidance for pumped systemspump stations.
