Project Summary
Horquetas community in Costa Rica uses septic tanks as the common way for treating wastewater, this water is often discharged directly over land contaminating the surrounding environment. To avoid this problem, it is necessary to construct a centralized wastewater system that will collect the wastewater and bring it to a treatment facility to be processed. This site and treatment process must align with the community values and interest while meeting standards and achieving cost efficiency.
Design Goal
The goal of our project is to design a centralized wastewater treatment composed of a water treatment facility and pipe collection network for the community of Horquetas, Costa Rica.
Design Constraints
