Metrovías S.A. is an Argentine privately held company that operates the Metropolitan services of the Urquiza Line. 90% of Metrovías' shares are held by Grupo Roggio. Metrovías was also operator of the Buenos Aires Underground from 1995 to December 2021, when "Emova Movilidad S.A." took over the concession of the service for 12 years. Emova is also part of the Roggio Group and also associated with Metrovías.
Water supply and sanitation in Colombia have been improved in many ways over the past decades. Between 1990 and 2010, access to improved sanitation increased from 67% to 82%, but access to improved water sources increased only slightly from 89% to 94%. In particular, coverage in rural areas lags behind. Furthermore, despite improvements, the quality of water and sanitation services remains inadequate. For example, only 73% of those receiving public services receive water of potable quality and in 2006 only 25% of the wastewater generated in the country underwent any kind of treatment.
Uruguay is the only country in Latin America that has achieved quasi-universal coverage of access to safe drinking water supply and adequate sanitation. Water service quality is considered good, with practically all localities in Uruguay receiving disinfected water on a continuous basis. 70% of wastewater collected by the national utility was treated. Given these achievements, the government's priority is to improve the efficiency of services and to expand access to sewerage, where appropriate, in areas where on-site sanitation is used.
Water supply and sanitation in Chile were once considered efficient and equitable but in 2022 Chile struggled to reliably provide water throughout the country. Chile's water resources have been strained by the Chilean water crisis, which was partially caused by a continuing megadrought that began in 2010, along with an increased demand for agricultural and other commercial interests.
Drinking water supply and sanitation in Argentina is characterized by relatively low tariffs, mostly reasonable service quality, low levels of metering and high levels of consumption for those with access to services. At the same time, according to the WHO, 21% of the total population remains without access to house connections and 52% of the urban population do not have access to sewerage. The responsibility for operating and maintaining water and sanitation services rests with 19 provincial water and sewer companies, more than 100 municipalities and more than 950 cooperatives, the latter operating primarily in small towns. Among the largest water and sewer companies are Agua y Saneamientos Argentinos (AYSA) and Aguas Bonarenses S.A. (ABSA), both operating in Greater Buenos Aires, Aguas Provinciales de Santa Fe, and Aguas Cordobesas SA, all of them now publicly owned. In 2008 there were still a few private concessions, such as Aguas de Salta SA, which is majority-owned by Argentine investors, and Obras Sanitarias de Mendoza (OSM).
Ferrocarriles Metropolitanos S.A. was a company set up by the Argentine government in 1991, during the presidency of Carlos Menem, to oversee the privatisation of commuter rail services within the city of Buenos Aires in Argentina. The company granted concessions to Metropolitano, Ferrovías, Metrovías, and Trenes de Buenos Aires for the operation of services which had previously been run by state-owned companies since the nationalisation of the railways in 1948. With its task complete, FEMESA was wound up in 1997.
The Sarmiento line is a broad gauge commuter rail service in Buenos Aires Province, Argentina, run by the state-owned Trenes Argentinos since 11 September 2013.
The Belgrano Sur line is an Argentine 1,000 mmmetre gauge commuter rail service in the Greater Buenos Aires area, currently operated by state-owned enterprise Trenes Argentinos. The Belgrano Sur runs over tracks and through stations built by the Franco–Belgian-owned Compañía General de Buenos Aires and British Midland companies at the beginning of the 20th century.
Railway privatisation in Argentina was a process which began in 1989 under the presidency of Carlos Menem, following a series of neoliberal economic reforms. This primarily consisted of breaking up the state-owned railway company Ferrocarriles Argentinos (FA) and allowing the former lines to be operated by private companies instead of the state.
The Argentine railway network consisted of a 47,000 km (29,204 mi) network at the end of the Second World War and was, in its time, one of the most extensive and prosperous in the world. However, with the increase in highway construction, there followed a sharp decline in railway profitability, leading to the break-up in 1993 of Ferrocarriles Argentinos (FA), the state railroad corporation. During the period following privatisation, private and provincial railway companies were created and resurrected some of the major passenger routes that FA once operated.
The privatization of water and sanitation services in Argentina between 1991 and 1999 under the government of Carlos Menem was part of one of the world's largest privatization programs. Water and sanitation concessions with the private sector were signed in 28% of the country's municipalities, covering 60% of the population.
The debate about water supply and sanitation in Mendoza has been dominated by the controversial private concession for the provincial water company OSM granted in 1998 to a consortium led by Enron. While the concession improved water and sanitation services, it failed to meet all its specified targets. After the collapse of Enron the concession was overtaken by Argentine investors.
The Palace of Running Waters is an architecturally significant water pumping station in Buenos Aires, Argentina and the former headquarters of Obras Sanitarias de la Nación. It is currently administered by Agua y Saneamientos Argentinos (AySA).
Integrated urban water management (IUWM) in Buenos Aires is not unlike many large urban areas in Latin America where in past decades, more focus was placed on just a few sectors or perhaps only one sector. The water management philosophy in Buenos Aires has evolved to one that is integrating efforts in reducing water pollution, improving stormwater management, adding drainage infrastructure, and improving water supply and sanitation (WSS). Primary challenges in urban water management continue to be flood control and stormwater management as Buenos Aires is situated in the low-lying pampas region where heavy rain is expected all year long. Adding to the challenges, urbanization has outpaced planning and development in the various water sectors. Efforts have been made to control the major tributaries of Río de la Plata such as channelizing and building culverts into urban rivers, however, this has increased flooding as the natural meander and saturating ability of the rivers have been lost. Rapid urbanization and very large quantities of industrial discharge have also caused severe contamination of the water basins that Buenos Aires is built upon. The Matanza-Riachuelo river (MR), a tributary of the Río de la Plata, is a prime example and has become the most contaminated basin in Argentina.
National Route 1, also known as Buenos Aires–La Plata Highway and officially called Autopista Doctor Ricardo Balbín since 2004, is a highway that connects the 25 de Mayo Highway and Paseo del Bajo in the city of Buenos Aires with the Provincial Route 11, near the city of La Plata. It has a length of 50 km (31 mi) with two or four lanes on each direction in different areas, and is indicated in red in the map.
The Official Post Service of the Argentine Republic is the state-owned company that covers the postal service in Argentina. The company is a S.A. under the country's Office of the Cabinet Chief.
The CSR EMU is a series of electric multiple unit cars manufactured by CSR Corporation Limited for use on Buenos Aires' commuter rail network. As of 2015, the trains operated on three of the city's lines and 705 cars were manufactured, with each line using a different number of cars per train. They were created for use on lines electrified using both third rail and overhead lines.
