Design of a Dual Stormwater and Wastewater Sanitation System Adapted to the Impacts of Climate Change: The Case of the Cité du Savoir, Haiti

The thesis proposes a dual system for the Cité du Savoir, a campus and urban development project of the Pôle d'innovation du Grand Nord (PIGraN) at Génipailler, in the commune of Milot. The system collects stormwater and wastewater for treatment and reuse in a central reclamation facility, and the author applies the water balance method to illustrate the principles. The study expects lower rainfall and presents recovery and reuse of rainwater and wastewater as an adaptation to drought.

In the water balance for the current year, 12 percent of the water infiltrates, 23 percent runs off and 65 percent is lost to evapotranspiration, and the thesis reports a rainfall deficit of 60 percent in the study area. The proposal also uses biogas, and the author says the reclaimed water could serve drinking water production, fishing, livestock and agriculture without groundwater. The cost is estimated at 34 million euros, and the author presents the design as a model that can be adapted to other projects in the country.
