The objective of this research was to evaluate if Peru’s Quality Infrastructure, with respect to the Peruvian Technical Standards (NTP), the testing laboratories, and the Peruvian legal framework, is sufficient to enable compliance with national regulation regarding nondomestic wastewater that is discharged into the sewerage system in Peru. To achieve this objective, three surveys were conducted related to the usefulness and value of Peruvian Technical Standards, the analytical capacity of laboratories in the regions, and the performance characteristics related to the reliability of results. National legislation was also analyzed in comparison with 10 countries from 5 regions of the world. It was found that there are NTPs for the 23 regulated parameters of Maximum Allowable Values (VMA) with an average percentage of positive valuation of 83.48%. However, these NTPs are not applied in accreditation. There are accredited laboratories for all 23 VMA parameters that apply standardized methods for at least 76% of the basic parameters, with little or no accredited offer for complementary tests. Accredited laboratories apply performance characteristics of reliability of results for all the tests they apply, unlike non-accredited laboratories. Regarding their coverage at a national level, there are 43 accredited laboratories in 9 regions of the country, with 65% concentrated in Lima and Callao. Only 4 regions have laboratories to test all 23 VMA parameters. The regions where Sanitation Service Providers (EPS) have the best capacity to manage VMAs are where there are accredited laboratories. Based on the comparative analysis of national legislation from 10 countries, it is shown that the 23 VMA parameters are adequate. The analysis supports their technical validity, although there are differences in the form and frequency of sampling. In conclusion, the capacity of Peru’s Quality Infrastructure enables compliance with the VMAs established in the national legislation, and several strengths have been identified, such as existence of NTPs, accredited laboratories with the required reliability, reference materials, and legislation with adequate parameters and limits. However, further development and deployment is required in terms of the use of NTPs, in expanding the coverage of accredited laboratories, in facilitating access to reference materials for the most important pollutants based on effluents from industries with the greatest impact on non-domestic wastewater discharge, and in the revision of national legislation in some key aspects regarding control.
