Reference excerpt

Access to drinking water and sanitation in El Salvador has been increased significantly. A 2015 conducted study by the University of North Carolina called El Salvador the country that has achieved the greatest progress in the world in terms of increased access to water supply and sanitation and the reduction of inequity in access between urban and rural areas. However, water resources are heavily polluted and the great majority of wastewater is discharged without any treatment into the environment. Institutionally a single public institution is both de facto in charge of setting sector policy and of being the main service provider. Attempts at reforming and modernizing the sector through new laws have not borne fruit over the past 20 years.

Access In 2015, 98% of the total population in El Salvador had access to "at least basic" water and 93% had access to "at least basic" sanitation. Nevertheless, there were still, in 2015, 428 thousand people without access to "at least basic" water and 551 thousand without access to "at least basic" sanitation. Access to water and sanitation in El Salvador remains low by regional standards. Access to improved water source stood at 88 percent in 2010 and access to improved sanitation at 87 percent. Access is lower in rural areas, where about 36 percent of the population lives. In 2010, it stood at 76% for improved water and 83 percent for improved sanitation.

Productivity and public health impact of lack of access to water supply and sanitation The lack of access to water impacts not only the quality of life of the poor, but also productivity and health. According to a survey carried out in 2001 by the Salvadoran think tank FUSADES the rural poor in particular spend a significant share of their productive time collecting water. Families without household access to water spent on average 8.5 percent of their productive time fetching water, while even those with household access spent 4.9 percent of their productive time fetching water. For the structural poor the values were much higher with 13.6 percent and 7.1 percent respectively. While access has improved the remaining lack of access to water and sanitation in rural areas has a demonstrably adverse effect on infant mortality, child mortality and stunting. The infant mortality rate among households without a house connection is 40 per 1,000 births, compared to 30 for households with a connection. Similarly, the infant mortality rate among households without a toilet is 37, compared to 30 for households with toilets. The toilets have no toilet seats. Most homes do not have baths.

Service quality Water supply in most localities served by ANDA is intermittent, varying from 16 hours per day in some areas to less than 4 hours per day or even once every four days, according to a Demographic and Health Survey (called FESAL by its Spanish acronym) carried out in 2002. Most localities, however, seem to receive water at least once a day. The microbiological quality of water is insufficient.

Water resources and pollution

El Salvador's water resources are highly polluted, owing in part to the almost total absence of municipal wastewater treatment. In addition, the country suffers from water scarcity during the dry season and conflicts among users. It is estimated that 90 percent of the surface water bodies are contaminated. Nearly all municipal wastewater (98 percent) and 90 percent of industrial wastewater is discharged to rivers and creeks without any treatment. The highest priority for pollution abatement is estimated to be in the basins of the Acelhuate River and Sucio River, an area that supplies a third of the water supply of the Metropolitan area of San Salvador. Over the past 20 years the yield of a sample of springs declined by 30 percent due to deforestation. This has reduced water availability for the rural population, in some cases obliging them to rely on more expensive wells pumping from aquifers whose water table has declined by as much as 1 meter per year in some localities.

History There have been various efforts to reform the water sector and to create a new legal framework since the mid 1990s. The most comprehensive effort was abandoned after the 2001 earthquakes when political and reform priorities shifted. That reform package would have included the setting of tariffs based on the goal of cost recovery, the creation of a regulator and the introduction of private sector participation. The government of Antonio Saca (2005–2009) considered a general water bill and a water and sanitation bill. According to the water and sanitation bill, ANDA would have limited its functions to service provision. None of the bills was passed until Mauricio Funes assumed the Presidency in June 2009.

Responsibility for water supply and sanitation

Service provision

Water supply and sanitation in El Salvador are the responsibility of a large number of diverse service providers.

ANDA The dominant service provider is the Administración Nacional de Acueductos y Alcantarillados (ANDA), which provides services to 40 percent of the total population of El Salvador in 149 out of the country's 262 municipalities, including the metropolitan area of San Salvador and the country's other two main cities, Santa Ana and San Miguel. As an umbrella institution ANDA defines policies, regulates and provides services. ANDA's Board Chairman has the rank of a Minister and reports directly to the President of the Republic.

Other service providers Other service providers include municipalities, decentralized service providers, housing developers and rural cooperatives. 83 mostly small municipalities provide services directly. More than 13 decentralized service providers have signed agreements under which ANDA has given them the right to manage their services autonomously. More than 100 housing developers have often built their own autonomous urban water systems because ANDA was unable to connect them. They now operate these systems themselves or have delegated service provision to user associations. In rural areas services are provided by more than 800 community-based organizations, including Juntas de Agua and cooperative development associations (Asociaciones de Desarrollo Comunitario). The latter serve about 30 percent of the population.

Worked examples

Example 1 — a first encounter with Water supply and sanitation in El Salvador

Start with the simplest possible case. Write down what Water supply and sanitation in El Salvador claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Water supply and sanitation in El Salvador before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Water supply and sanitation in El Salvador ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.
