In Brazil, only 50.3% of the sewage volume is effectively treated. The data are in the Thematic Diagnosis on the Provision of Basic Sanitation Services in the country, presented this Tuesday (13) by the Ministry of Regional Development (MDR). According to the document, which is based on the National Sanitation System (SNIS), despite the low average, in cities the scope of data collection related to sanitary sewage has grown. Service by sewage networks reached a total of 114.8 million inhabitants in 2021, an increase of 2.4 million new inhabitants served, that is, 2.1% compared to 2020. data referring to sanitary sewage corresponded to 4,774 municipalities (85.7% of the total Brazilian municipalities), representing an urban population of 174.9 million inhabitants (96.7% of the total population of the country). Water supply With regard to water supply, 84.2% of the country’s total population has access to the treated network. When the cut is made in the urban area, 167.5 million inhabitants (93.5% of the country’s urban population) have access to services. The South macro-region had the highest rate of urban attendance, with 98.9%, followed by the Midwest (97.8%), Southeast (96.1%), Northeast (90.1%) and North (72.2%). %). The survey also points out the rate of losses in water distribution, resulting from leaks, irregular connections or measurement failures. For the year 2021, losses in the distribution of drinking water reached 39.3%, 0.8 percentage points less than that recorded in the previous year. Drinking water made available not accounted for or lost in distribution corresponds to 39.3%. Cleaning and solid waste This year, SNIS presents, for the first time, analyzes on the situation of final disposal of urban solid waste in Brazilian municipalities and on the closure of operations at dumps. “2,318 municipalities were identified that declared sending part or all of their solid urban waste to inadequate final disposal units (dumps or controlled landfills), whether located in the territory of the declaring municipality or in a shared unit located in another municipality. Regarding the closure of operations at inadequate disposal units, in 2021, the closure of operations at 324 units (234 dumps and 90 controlled landfills) throughout the national territory were accounted for”. Regarding solid waste, information was gathered from 4,900 municipalities (88% of the total Brazilian municipalities), representing 203.7 million inhabitants (95.5% of the total population) and 175.4 million inhabitants of areas urban areas in the country (97% of the urban population). Household collection coverage served 98.3% of the urban population, with collection estimated at 65.63 million tons (equivalent to 0.99 kg per inhabitant/day) of household and public waste, of which 1.75 million is collected selectively. Drainage and stormwater With regard to drainage and management of urban stormwater, the diagnosis gathered data from 4,573 municipalities (82.1% of all Brazilian municipalities), covering 93.2% of the urban population (168.4 million inhabitants). . The survey points out that 66.2% of the municipalities in the sample do not have the mapping of areas at risk of flooding in urban watercourses. “This mapping makes it possible to identify the number of households at risk of flooding. For 2021, there was a 4% index of households at risk of flooding. It is also recorded that the number of people homeless or displaced in the urban areas of the municipalities, due to impacting hydrological events (floods, floods and floods), is 319,309 inhabitants”. SNIS The National Sanitation Information System (SNIS), managed by the National Sanitation Secretariat of the Ministry of Regional Development (SNS/MDR) gathers operational, managerial, financial and quality information on Water and Sewage services (since 1995) , Urban Solid Waste Management (since 2002) and Urban Rainwater Drainage and Management (since 2015). Indicators produced from this information are a reference for the formulation of public policies, for monitoring the evolution of the sanitation sector in Brazil and comparing the performance of service provision. The data collection cycle is annual and begins in April, after the closure of the balance sheets of the sector’s service providers, with the availability of electronic forms to providers or municipalities, responsible for the operation of sanitation services. “Access to information published by the SNIS is public and free. In addition to the Thematic Diagnoses, such information is available in the SNIS Série Histórica application, where it is possible to carry out consultations and cross-checks of personalized data”, recalled the MDR.
