Know How Drinking Water production and distribution Domestic Wastewater collection, transport and
treatment Storm Water systems Flooding control Hydraulic Works Industrial wastewater collecting and treatment
Preliminary Studies Strategic Planning Design Procurement
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
CSI first projects in stormwater design: 90’s
Hydraulic model: CAREDAS (Sogreah) of the combined sewer network of the Paraguay functional unit (2.920 hectares). The goal of the project is to eliminate discharges to the bay as overflowing during rainfall.
Sewage and Pluvial Network Cerro Norte - La Paloma (Montevideo, 2002)
Storm water projects in vulnerable socio-economic areas
Area: 490 hectares Population: 52.000 inhabitants. Four small streams cross public and private grounds, and are in part flanked by precarious homes, with obstructions and overflow problems caused by garbage and fills without planning.
Sewage and Pluvial Network Rincón del Cerro – Casabó (Montevideo, 2003)
Area: 304 hectares. Population: 34.000 inhabitants A main stream, a dam and several affluents. Precarious homes in the margins, problems of obstructions and overflow.
Plan Set of the Sanitation, Pluvial Waters and Street System of Ciudad de la Costa (Canelones, 2011)
Projects including stormwater retention
Area: 2.150 hectares Population: 99.200 inhabitants. Extremely flat topography. • Retention ponds • Ditch retention
Storm Drainage Project Arroyo Seco y Quitacalzones Basins (Montevideo, 2013)
Area: 1.500 hectares. • 5 closed lamination tanks between
2.000 and 11.000 m3.
Final Plan Set of a Storm Drainage System in Libertad Neighborhood, Juan Lacaze (Colonia, 2013)
• Stormwater pumping station; 3,6 m3/s • A lamination tank of 1500 m3.
Urban Water Plan Ciudad del Plata. (San José)
Projects being developed
Area: 13.000 hectares Population: 30.000 inhabitants. General Objective: long term goals and middle and short term action plan.
Montevideo Sanitary and Urban Drainage Master Plan
Area: 430 km2 Population: 1.350.000 inhabitants.
