Water supply and sanitation in Pernambuco

Last updated April 22, 2019

Water supply and sanitation in Pernambuco is characterized by high levels of access to water supply in urban areas, but also by poor service quality (intermittent supply), inadequate access to sanitation, and insufficient access to improved water sources and improved sanitation in rural areas.

Water supply is the provision of water by public utilities, commercial organisations, community endeavors or by individuals, usually via a system of pumps and pipes. Irrigation is covered separately.

Sanitation refers to public health conditions related to clean drinking water and adequate treatment and disposal of human excreta and sewage. Preventing human contact with feces is part of sanitation, as is hand washing with soap. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of disease, especially through the fecal–oral route. For example, diarrhea, a main cause of malnutrition and stunted growth in children, can be reduced through sanitation. There are many other diseases which are easily transmitted in communities that have low levels of sanitation, such as ascariasis, cholera, hepatitis, polio, schistosomiasis, trachoma, to name just a few.

An improved water source is a term used to categorize certain types or levels of water supply for monitoring purposes. It is defined as a type of water source that, by nature of its construction or through active intervention, is likely to be protected from outside contamination, in particular from contamination with fecal matter.

In urban areas, where 76% of Pernambuco's 8.4 million inhabitants live, access to house connections for water supply is 91% and access to sewerage is 49%. Concerning service quality, rationing is a constant reality in about 85% of the municipalities, including the Recife Metropolitan Region. This is primarily to a lack of water resources, particularly during the dry season, and frequent drought conditions.

Pernambuco is a state of Brazil, located in the Northeast region of the country. The state of Pernambuco also includes the archipelago Fernando de Noronha. With an estimated population of 9.2 million people in 2013, it is the seventh most populous state of Brazil, and is the sixth most densely populated and the 19th most extensive among the states and territories of the country. Its capital and largest city, Recife, is one of the most important economic and urban hubs in the country. As of 2013 estimates, Recife's metropolitan area is the fifth most populous in the country, and the largest urban agglomeration in Northeast Brazil.

Recife is the fourth-largest urban agglomeration in Brazil with 4,031,485 inhabitants, the largest urban agglomeration of the North/Northeast Regions, and the capital and largest city of the state of Pernambuco in the northeast corner of South America. The population of the city proper was 1,625,583 in 2016. The first slave port in the Americas, Recife was founded in 1537, during the early Portuguese colonization of Brazil, as the main harbor of the Captaincy of Pernambuco, known for its large scale production of sugar cane. It was the former capital Mauritsstad of the 17th century colony of New Holland of Dutch Brazil, established by the Dutch West India Company. The city is located at the confluence of the Beberibe and Capibaribe rivers before they flow into the South Atlantic Ocean. It is a major port on the Atlantic. Its name is an allusion to the stone reefs that are present by the city's shores. The many rivers, small islands and over 50 bridges found in Recife city centre characterise its geography and led to the city being called the "Brazilian Venice". As of 2010, it is the capital city with the highest HDI in Northeast Brazil and second highest HDI in the entire North and Northeast Brazil.

Drought extended period when a region notes a deficiency in its water supply

A drought or drouth is a natural disaster of below-average precipitation in a given region, resulting in prolonged shortages in the water supply, whether atmospheric, surface water or ground water. A drought can last for months or years, or may be declared after as few as 15 days. It can have a substantial impact on the ecosystem and agriculture of the affected region and harm to the local economy. Annual dry seasons in the tropics significantly increase the chances of a drought developing and subsequent bush fires. Periods of heat can significantly worsen drought conditions by hastening evaporation of water vapour.

The State Secretariat of Water Resources (SRH) is in charge of both water resources management and water supply and sanitation policies. The State Water Company (COMPESA) is responsible for water and sanitation service provision in most of the state. COMPESA provides urban water supply and sewerage in 170 and 20 municipalities respectively, out of 189 in the State. The remaining municipalities are served by municipal public providers. COMPESA operates under concession contracts with municipalities and is regulated and supervised by the state-level multi-sector regulatory agency ARPE.

The city of Recife has pioneered condominial sewers in Brazil.

Simplified sewerage, also called small-bore sewerage, is a sewer system that collects all household wastewater in small-diameter pipes laid at fairly flat gradients. Simplified sewers are laid in the front yard or under the pavement (sidewalk) or - if feasible - inside the back yard, rather than in the centre of the road as with conventional sewerage. It is suitable for existing unplanned low-income areas, as well as new housing estates with a regular layout. It allows for a more flexible design. With simplified sewerage it is crucial to have management arrangements in place to remove blockages, which are more frequent than with conventional sewers. It has been estimated that simplified sewerage reduces investment costs by up to 50% compared to conventional sewerage.

Water supply and sanitation in Latin America is characterized by insufficient access and in many cases by poor service quality, with detrimental impacts on public health. Water and sanitation services are provided by a vast array of mostly local service providers under an often fragmented policy and regulatory framework. Financing of water and sanitation remains a serious challenge.

Water supply and sanitation in Colombia has 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 source's 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.

Access to at least basic water increased from 94% to 97% between 2000 and 2015; an increase in access to at least basic sanitation from 73% to 86% in the same period;

Bolivia's drinking water and sanitation coverage has greatly improved since 1990 due to a considerable increase in sectoral investment. However, the country continues to suffer from what happens to be the continent's lowest coverage levels and from low quality of services. Political and institutional instability have contributed to the weakening of the sector's institutions at the national and local levels. Two concessions to foreign private companies in two of the three largest cities—Cochabamba and La Paz/El Alto—were prematurely ended in 2000 and 2006 respectively. The country's second largest city, Santa Cruz de la Sierra, relatively successfully manages its own water and sanitation system by way of cooperatives. The government of Evo Morales intends to strengthen citizen participation within the sector. Increasing coverage requires a substantial increase of investment financing.

The water and sanitation sector in Peru has made important advances in the last two decades, including the increase of water coverage from 30% to 85% between 1980 and 2010. Sanitation coverage has also increased from 9% to 37% from 1985 to 2010 in rural areas. Advances have also been achieved concerning the disinfection of drinking water and in sewage treatment. Nevertheless, many challenges remain, such as:

Costa Rica has made significant progress in the past decade in expanding access to water supply and sanitation, but the sector faces key challenges in low sanitation connections, poor service quality, and low cost recovery.

The Dominican Republic has achieved impressive increases in access to water supply and sanitation over the past two decades. However, the quality of water supply and sanitation services remains poor, despite the country's high economic growth during the 1990s.

Rapid improvements are being made in augmenting drinking water supply and sanitation in India, due to concerted efforts by the various levels of government and communities at improving coverage. The level of investment in water and sanitation, albeit low by international standards, has increased in size during the 2000s. For example, in 1980 rural sanitation coverage was estimated at 1% and reached 95% in 2018. Also, the share of Indians with access to improved sources of water has increased significantly from 72% in 1990 to 88% in 2008. At the same time, local government institutions in charge of operating and maintaining the infrastructure are seen as weak and lack the financial resources to carry out their functions. In addition, only two Indian cities have continuous water supply and according to an estimate from 2018 about 8% of Indians still lack access to improved sanitation facilities. A study by Water Aid estimated as many as 10 million Indians, or 5 percent of Indians living in urban areas, live without adequate sanitation. India comes in first place globally for having the greatest number of urban-dwelling inhabitants living without sanitation. India tops the urban sanitation crisis, has the largest amount of urban dwellers without sanitation, and the most open defecators(urban) with over 5 million people.

Access to water supply and sanitation in Ethiopia is amongst the lowest in Sub-Saharan Africa and the entire world. While access has increased substantially with funding from foreign aid, much still remains to be done to achieve the Millennium Development Goal of halving the share of people without access to water and sanitation by 2015, to improve sustainability and to improve service quality.

Water supply and sanitation in China is undergoing a massive transition while facing numerous challenges such as rapid urbanization, increasing economic inequality, and the supply of water to rural areas. Water scarcity and pollution also impact access to water.

Water supply is the process of providing water in a systematic way through installed pumps and pipe lines. Before water is provided to a specific area, it undergoes a process called sanitation to ensure that the quality of water received is safe for human consumption. The Philippines’ water supply system dates back to 1946 after the country achieved its independence. Government agencies, local institutions, non-government organizations, and other corporations are primarily in charge in the operation and administration of water supply and sanitation in the country.

Water supply and sanitation in Zambia is characterized by achievements and challenges. Among the achievements are the creation of regional commercial utilities for urban areas to replace fragmented service provision by local governments; the establishment of a regulatory agency that has substantially improved the availability of information on service provision in urban areas; the establishment of a devolution trust fund to focus donor support on poor peri-urban areas; and an increase in the access to water supply in rural areas.

Water management in the Metropolitan Region of São Paulo, Brazil faces several challenges, including pollution of drinking water reservoirs that are surrounded by slums, water scarcity leading to conflicts with the Campinas Metropolitan area to the north, inefficient water use, and flooding. The sprawling Metropolitan Region of São Paulo (MRSP) with close to 20 million people is the seventh most populous urban area in the world and the economic, financial and technical hub of Brazil. The main stakeholders in water management in MRSP are the state government, the state water and sanitation utility Sabesp and 39 municipal governments. A basin committee for the Alto Tietê basin, which covers the entire area of the MRSP and supplies half of its water, brings together all stakeholders. It has drawn up two master plans for the management of water resources in the basin. The first was approved in 2003 and focused on urban sprawl. The second was approved in 2009 and focused on water use conflicts.

Water supply and sanitation in Tanzania is characterised by: decreasing access to at least basic water sources in the 2000s, steady access to some form of sanitation, intermittent water supply and generally low quality of service. Many utilities are barely able to cover their operation and maintenance costs through revenues due to low tariffs and poor efficiency. There are significant regional differences and the best performing utilities are Arusha and Tanga.

Water resources management in Belize is carried out by the Water and Sewerage Authority (WASA) in most cases. One of the primary challenges the country is facing with regard to water resources management, however, is the lack of coordinated and comprehensive policies and institutions. Furthermore, there are various areas of water management that are not well addressed at all such as groundwater data and provision of supply. Data on irrigation and drainage is not adequately available either. Demand on water resources is growing as the population increases, new economic opportunities are created, and the agriculture sector expands. This increased demand is placing new threats on the quality and quantity of freshwater resources. Other constant challenge for management entities are the constant threat of floods from tropical storms and hurricanes. The Belize National Emergency Management Organization (NEMO) is charged with flood management as they occur but it is unclear what institution has responsibility for stormwater infrastructures.

Water supply and sanitation in Kenya is characterised by low levels of access to water and sanitation, in particular in urban slums and in rural areas, as well as poor service quality in the form of intermittent water supply. Seasonal and regional water scarcity exacerbates the difficulty to improve water supply.

Water supply and sanitation in Turkey is characterized by achievements and challenges. Over the past decades access to drinking water has become almost universal and access to adequate sanitation has also increased substantially. Autonomous utilities have been created in the 16 metropolitan cities of Turkey and cost recovery has been increased, thus providing the basis for the sustainability of service provision. Intermittent supply, which was common in many cities, has become less frequent. In 2004, 61% of the wastewater collected through sewers was being treated.

Although access to water supply and sanitation in Sub-Saharan Africa has been steadily improving over the past two decades, the region still lags behind all other developing regions. Access to improved water supply has increased from 49% in 1990 to 60% in 2008, while access to improved sanitation has only risen from 28% to 31%. Sub-Saharan Africa is unlikely to meet the Millennium Development Goals of halving the share of the population without access to safe drinking water and sanitation between 1990 and 2015. There are, however, large disparities among Sub-Saharan countries, and between the urban and rural areas.

Water supply and sanitation in Iraq is characterized by poor water and service quality. Three decades of war, combined with limited environmental awareness, have destroyed Iraq's water resources management system. Thus, Iraq faces difficulties to realize the target of 91% of households using safe drinking water supply by 2015. Currently, 16% of households report daily problems with supply and 20% use an unsafe drinking water source. Furthermore, animal waste and septic tanks pollute the drinking water network.(11)
