Issues with conventional sewage collection • Massive & expensive infrastructure projects, long lead time • Disruption to surrounding environment, residents & local businesses • <strong>Treatment</strong> plants must be oversized due to groundwater infiltration & inflow • High maintenance cost to repair/replace lift stations and piping • Potential surface/ground water contamination as a result of overflow discharge 6 6
Issues with historic sewage collection in arid and developing regions • With < 1/3 water use in water-scarce areas, traditional gravity sewer service is technically unfeasible – Insufficient effluent flow to convey solids to sewage treatment plant – Fresh water resources a priority for drinking water and agricultural use • Sewage handling is labor-intensive and inefficient 7 7
