Description
Summary:The Environmental Sanitation Project of the Public Works Company of Heredia (ESPH, for its name in Spanish) aims at treating the wastewater being generated in the municipalities of Heredia, San Rafael and San Isidro in a centralized system. However, it has faced the problem that certain settlements in San Isidro cannot be connected directly to the proposed sewerage network. Based on the efficiency and adaptability of the different treatment alternatives, this research proposes decentralized wastewater treatment systems for the settlements that require them. The methodology considers the variables of population growth and density, land use zoning, spatial availability and closeness to a waterbody in order to classify the settlements into four archetypal typologies sharing similar conditions to facilitate the selection of decentralized treatment options for each settlement.
