Altamira Case Study Caroline Gerwe David Wortman Tanya Hoogerwerf
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
Water Supply • Communal water taps • Low water pressure • Delivered from Altamira Municipality • 200 l/person/day
Sanitation Facilities • Basic pit latrines • Modified (VIP) pit latrines • Gray water runoff
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
Decision Making Factors • Flooding • Population Growth • Educational Level • Economic Situation • Groundwater Level and Soil Type • Gas Lines Hazard
Collection System Options • Non-Conventional • Latrines • Septic Systems • On-site effluent treatment • Septic tank effluent gravity sewers • Conventional
Treatment Optionsfor Collected Wastewater • Lagoons • Anaerobic • Facultative • Maturation Ponds • Wetlands • Subsurface • Free water Surface
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
