  1. Altamira Case Study Caroline Gerwe David Wortman Tanya Hoogerwerf

  2. Background • Comprised of 5 neighborhoods • Presents many health hazards • Minimal water supply • Lack of basic sanitation facilities • Situated on top of dump • Soil erosion problems • In the middle of an oil field

  3. Water Supply • Communal water taps • Low water pressure • Delivered from Altamira Municipality • 200 l/person/day

  4. Sanitation Facilities • Basic pit latrines • Modified (VIP) pit latrines • Gray water runoff

  5. Additional Hazards

  6. Objectives • Research conventional and non-conventional wastewater collection and treatment systems • Conduct an economic analysis on each system • Propose a system that best fits the needs and conditions of the Altamira community

  7. Decision Making Factors • Flooding • Population Growth • Educational Level • Economic Situation • Groundwater Level and Soil Type • Gas Lines Hazard

  8. Collection System Options • Non-Conventional • Latrines • Septic Systems • On-site effluent treatment • Septic tank effluent gravity sewers • Conventional

  9. Treatment Optionsfor Collected Wastewater • Lagoons • Anaerobic • Facultative • Maturation Ponds • Wetlands • Subsurface • Free water Surface

  10. Sewer Network

  11. Economic Analysis

  12. Final Design Proposed • Current and New Residents • Latrines, for those currently installed • Septic systems with on-site collection, but the ability to hook up to a collection system • In 10 years (with re-evaluation) install sewers and build wetland

  13. Fun Stuff
