CSI first projects in stormwater design: 90 s Sewer and Rainwater Network of Sayago Norte, Peñarol and Ferrocarril Neighborhoods (Montevideo) - 1995 Population to be served at the end of the design period (year 2035) is 30.000 inhabitants. Served Area: 650 hectares. Modification of Weirs and Auxiliary Works of the Paraguay Wastewater System (Montevideo)- 1997 Hydraulic model: CAREDAS (Sogreah) of the combined sewer network of the Paraguay functional unit (2.920 hectares).
