Description
The annual calculation of the Effective Water Treatment Indicator (TEAR) is a key tool to measure the country’s progress in the implementation of sustainable wastewater treatment and disposal practices. This indicator is part of target 6.3 of SDG 6, which seeks to improve water quality by reducing pollution, eliminating spills and minimizing emissions of hazardous chemicals and materials, halving the percentage of untreated wastewater and substantially increasing safe reuse and water recycling worldwide. The implementation of the annual TEAR calculation will allow to assess the country’s progress in meeting this target, identify areas in which greater attention is required and promote the adoption of more sustainable wastewater treatment and disposal practices.
The calculation of the indicator shows that, by 2021, 74% of the population was connected to a drainage network, 5% depended on septic wells and the remaining 21% had other forms of sanitation systems in situ (such as black wells or letrines) or practiced outdoor defecation.
By observing the proportion of safe-treated household wastewater flows, Peru has shown positive and sustained progress in household sewage treatment, rising from 16% in 2015 to 50% in 2021. This represents a growth of 34 percentage points and is derived from an increase in both the proportion of households connected to drainage and in the greater treatment capacity in PTARs (waste treatment plants managed by the country’s providers).
By observing PTAR treatment capacity, between 2016 and 2021, the proportion of waste water collected through drainage systems that received treatment increased from 66% to 79%. This increase of 13 percentage points was largely due to the launch of the La Chira plant, which now treats the wastewater of the southern districts of Lima. Of all wastewater received in PTARs, 65% were treated safely with wastewater that complies with national environmental standards.
