Sewage Water is wastewater generated by the Resident Communities and then discharged into Drains, Canals, etc. Sewage Water Testing Analyses Harmful Chemicals if present, in the said water. Sewage Water Treatment helps preserve Water Bodies, the Environment, and Public Health.
Sewage Water Samples in Indian Sewage Treatment Plants are required to comply with the ISO 5667-10: 2020 Regulations. They are also required to meet Scientific Parameters like COD, BOD, pH, and TOC.
EFRAC caters to ISO 5667-10: 2020 Guidelines and EPA 1986 Regulations in its Sewage Water Analysis. Highly trained Professionals operate the well-equipped Water Testing Laboratory enabling it to offer Accurate Results to its Clients.
