While many Mexican water supply and sewer service providers rank among the best in Latin America, in general, the Mexican water and sanitation sector is characterized by the following issues (i) poor technical and commercial efficiency of service provision; (ii) inadequate water service quality; and (iii) inadequate sanitation service quality, particularly concerning wastewater treatment; (iv) inadequate coverage, in particular in poorer rural areas.

This article is part of a series of articles describing water and sanitation in various countries around the world using the same categories to facilitate comparison. For more details see the links to articles on other countries in the section "see also".

During the past decade, the Mexican water and sanitation sector made major strides in service coverage with water supply and sanitation coverage. As shown above, in urban areas almost 100% of the population is estimated to have access to improved water supply and 91% to adequate sanitation. In rural areas, the respective shares are 87% for water and 41% for sanitation.[1] Coverage levels are particularly low in the South of the country.

Quality of service

Quality of service also leaves much to be desired. The 2000 census indicated that 55% of Mexican households with access to piped water received services on an intermittent basis. About 30% of wastewater is being treated, a share that is twice as high as the average for Latin America.[2]

Institutions and policies

According to the Mexican constitution responsibility for water supply and sanitation services delivery rests with 2,446 municipalities since the decentralization of 1983.[3] However, a few states deliver services through state water companies on behalf of municipalities. Most states also have established state water agencies that have different roles in each state, such as technical assistance to service providers, assisting in investment planning, and channeling of federal subsidies. [4] In some cases, the state agencies directly provide water and sanitation services. In rural areas, water boards (Juntas) are responsible for water supply.

Federal policies for water and sanitation are set by the Comision Nacional del Agua (CNA), a well-established autonomous entity under the Ministry of Environment. The sector strategy of the federal government focuses on providing investment subsidies to service providers through a variety of programs aiming to improve coverage and efficiency. A 2004 modification of the National Water Law envisaged the transfer of certain functions from both the federal and state levels to newly created institutions at the level of river basins, including financial decisions through the creation of a National Water Financial System. The provisions of the new law remain to be implemented.

Efficiency

The efficiency and quality of water and sanitation services vary widely, to a large extent reflecting different levels of development across the country. Mexico boasts some of the best-run public utilities in Latin America, such as Agua y Drenaje de Monterrey, but also has some utilities with dismal performance. On average, the level of non-revenue water in Mexico is 44%, about twice as high as for well-run utilities. Furthermore, on average only 72% of all bills are being paid.

Tariffs and cost recovery

Tariff levels and structures vary widely in Mexico from providers that fully recover all costs to those that do not even cover operating costs. The sector as a whole falls far short of generating sufficient revenues to cover full costs.

Financing

Investments are financed by federal subsidies (56% in 2003), subsidies (13%), housing developers (22%) and other sources (9%) including self-financing, credits and municipal subsidies. Federal subsidies are channeled through various programs, including sector-specific programs managed by CNA and the Fondo de Apoyo a la Infraestructura Social (FAIS), which is a transfer of tax revenues to municipalities for use at their own discretion in various infrastructure sectors.[5]
