The Experience of Aguas ArgentinasThe Aguas Argentina concession covers the greater Buenos Aires area, which includes the Federal District and the 13 surrounding municipalities belonging to the Province of Buenos Aires. All are connected to the same water supply and sewerage system. The water distribution network covers some 11,000 km and the sewerage network about 7,000 km; water production capacity is more than 3.6 million cubic meters per day. In 1991, only 70 percent of the 8.6 million people were connected to the public water supply and 58 percent to the sewerage system. Only 5 percent of the 2.2 million cubic meters per day of sewerage was treated at one plant; the rest was discharged into the La Plata River.
Coverage Targets: The program established by the concession contract established coverage goals of 82 percent of inhabitants by 2001 and 100 percent by 2023 for water supply; 66 percent by 2001 and 95 percent by 2023 for sewage collection; and 100 percent by 2023 for sewage treatment. To date, the most progress has been in extending water supply to 1.1 million additional people. In addition, a half million people have been connected to the sewerage system. No additional wastewater treatment has been achieved.
Water Quality: Water quality improved considerably during the first four years of operation. As of 1996, the principal water quality parameters comply with standards set by the World Health Organization and the Argentine Ministry of Health. Since 1993, both Aguas Argentina and ETOSS have been monitoring water quality throughout the system 24 hours a day, 7 days a week.
Investments: In the first two years of operation, close to $300 million were invested, and the company plans to invest an additional $1 billion during 1995-98. Total investments of more than $4 billion are anticipated more than the life of the 30-year concession to achieve the performance goals stipulated in the contract. The company has received financial support from the International Finance Corporation and the Japanese Government.
Plans Under Way: Aguas Argentina is investing $120 million to extend potable water to eight communities over the next years: Lomas de Zamora, Lanús, Avellaneda, San Martín, Tres de Febrero, San Fernando, San Isidro, and Vicente López. Plans include:
--Construction of an underground river of 15 km long and 3.5 meters wide that will transport potable water from Saavedra neighborhood, in Buenos Aires City, to supply 800,000 inhabitants in the Tres de Febrero and Moron neighborhoods. The investment is approximately $300 million.
--An increase of 30 percent of potable water from the General Belgrano plant in Bernal. The investment is approximately $20 million.
--Construction of the first plant for the purification of sewer liquids in San Fernando and optimization of the first establishment in La Matanza.

Common Treatment of Tannery WasteIn Avellaneda, the 16 members of a tannery association joined together to implement a long-range plan for wastewater treatment. The first step was to build a chrome-recovery facility, which began operating in 1995, to treat 200 cubic meters of chrome-laden wastewater per day. An Italian firm, Italprogetti, was contracted to design the plant, provide the equipment, and provide technical assistance. Funding was provided by the association. The plant is currently operated by Tratamiento de Efluentes Avellaneda, S.A. (TEA) and is currently operating at below capacity.
The original plan included two additional phases: the treatment of chrome-laden sludge from the treatment plant (estimated cost: $3-4 million) and the treatment of remaining organic material (estimated cost: $12 million). These have not been implemented.
