3 The Customer  Carabuela, Ecuador  HCJB Global (Herald Christ Jesus' Blessings) Bruce Rydbeck  Mostly indigenous tribes  Occupations Farm fields Weaving The TeamWastewaterThe ProblemDesign Norms Stormwater Current Status

4 The Problem  Carabuela, a village in Northern Ecuador, does not adequately treat its wastewater  Wastewater treatment One overloaded septic tank Failed leaching field  Combined sewer system (CSS) All roof drains connected into system Widely variable flows during rain events The TeamWastewaterThe ProblemDesign Norms Stormwater Current Status

5 Treatment Solution  Design a complete wastewater treatment process Irrigation WasteBar ScreensGrit Chamber Stabilization Lagoon Imhoff Tank Sludge Treatment The TeamWastewaterThe ProblemDesign Norms Stormwater Current Status

6 Design Alternatives  Bar Screen  Lagoon  Stabilization Ponds  Wetlands  Grit chamber Modified barrel for vortex Detritus tank  Sludge Treatment Drying beds Landfill Composting  Imhoff Tank New design Modify current septic tank The TeamWastewaterThe ProblemDesign Norms Stormwater Current Status

7 Treatment Goals The TeamWastewaterThe ProblemDesign Norms Stormwater Current Status  Removal Suspended Solids Pathogens ○ Helminths (worms) ○ Bacteria ○ Virus ○ Protozoa Biological Oxygen Demand

8 Stormwater Analysis  Remove roof drains from combined sewers Add rain barrels to catch roof drainage for possible reuse Convey roof water to river with ditch drainages Extend roof drains to open areas for infiltration The TeamWastewaterThe ProblemDesign Norms Stormwater Current Status

9 Why?  Stewardship  Promote sustainability  Cultural Appropriateness  Public Safety The TeamWastewaterThe ProblemDesign Norms Stormwater Current Status

10  In contact with HCJB in Ecuador  Gathering data about the location  Analyzing alternatives  Modeling alternatives Biggest Problem  Gathering data from a distant location  Cultural appropriateness The TeamWastewaterThe ProblemDesign Norms Stormwater Current Status
