Water is a chemical substance that is composed of hydrogen and oxygen and is vital for all known forms of life.
In typical usage, water refers only to its liquid form or state, but the substance also has a solid state, ice, and a gaseous state, water or steam. Water covers 71% of the Earth's surface. On Earth, it is found mostly in oceans and other large water bodies, with 1.6% of water below ground in aquifers and 0.001% in the air as vapor, clouds (formed of solid and liquid water particles suspended in air), and precipitation. Oceans hold 97% of surface water, glaciers and polar ice caps 2.4%, and other land surface water such as rivers, lakes and ponds 0.6%. A very small amount of the Earth's water is contained within biological bodies and manufactured products.
Water on Earth moves continually through a cycle of evaporation or transpiration (evapotranspiration), precipitation, and runoff, usually reaching the sea. Over land, evaporation and transpiration contribute to the precipitation over land.
Clean, fresh drinking water is essential to human and other life forms. Access to safe drinking water has improved steadily and substantially over the last decades in almost every part of the world. There is a clear correlation between access to safe water and GDP per capita. However, some observers have estimated that by 2025 more than half of the world population will be facing water-based vulnerability. A recent report (November 2009) suggests that by 2030, in some developing regions of the world, water demand will exceed supply by 50%. Water plays an important role in the world economy, as it functions as a solvent for a wide variety of chemical substances and facilitates industrial cooling and transportation. Approximately 70% of freshwater is consumed by agriculture.
WATER IN COLOMBIA
The Vice-Ministry of Water and Sanitation, created in October 2006 within the Ministry of Environment, Housing and Territorial Development is in charge of setting sector policy. This sector policy is defined in the framework of national policy established by the Departamento Nacional de Planificación (DNP) or National Planning Department.
Responsibility for regulating water services is vested in two separate institutions at the national level. The Comisión de Regulación de Agua Potable y Saneamiento Básico (CRA) or Potable Water and Basic Sanitation Regulatory Commission defines criteria for efficient service provision and sets the rules for tariff revision, but is not in charge of controlling the application of these rules. The latter is the responsibility of the Superintendencia de Servicios Públicos Domiciliarios (SSPD) or Superintendency for Residential Public Services, a multi-sector regulatory agency.
The Government aims at improving the performance of the water and sanitation sector through: (1) strengthening the regulatory framework; (2) implementing technical assistance programs; (3) providing financial support to promote modernization and efficient management as well as to subsidize the poor; and (4) rationalizing the institutional framework at the national level to improve coordination in the sector. The government also supports private sector participation in the sector.
Service provision
Colombian municipalities are responsible for “ensuring that their inhabitants are given domestic services of water supply and sanitation in an efficient way by public companies”. Therefore, public utilities are directly responsible for service provision, except for some special cases defined in the law, in which municipalities can offer the services directly. In rural areas and some marginal urban areas, communal water boards also offer water supply services.
Over the last few years, the number of companies has increased and the direct service provision by municipalities has decreased. To simplify the process of changing suppliers' ownership structure, municipal utilities were transformed into public stock corporations, which allow private sector participation without a further change of the legal status. In 2006, 53% of all suppliers were public companies, the remainder being direct municipal suppliers (15%), private companies (12%), official companies, which are companies that are not specialized in water and sanitation (13%), mixed companies (6%) and authorized organizations (1%).] Smaller utilities included, there are more than 1,500 water and sanitation service providers of in urban areas, and probably more than 12,000 communal organizations providing services in rural areas.
The sector is characterized by a high degree of fragmentation which makes it difficult to realize economies of scale, according to a World Bank study. To solve this problem, the creation of regional companies has been suggested.
Urban areas
Most Colombian cities - including the three largest ones, Bogota, Medellin and Cali - are served by public utilities. However, the private sector also plays an important role, including 125 private and 48 mixed public-private water companies in 2004 out of 1,500 urban service providers.
Public utilities
Some of Colombia's larger cities are home to well-performing public utilities, some of them providing multiple services, others being specialized in water and sanitation only. The Empresas Públicas de Medellin or Public Companies of Medellin, is a municipally-owned multi-sector utility in charge of water supply, sanitation, solid waste management, electricity generation and distribution as well as local telecommunications in Medellin and its surrounding areas.
Another multi-sector utility is the Empresas Municipales de Cali, which provides fixed line local telecoms, Internet, potable water, sewage and electricity services to some 600,000 clients.[ EMCALI has suffered financially due to onerous payment obligations resulting from a Power Purchase Agreement signed in 1997 with an Independent Power Producer, Termo Emcali.
