ETE CRATEUS 13 Wastewater Treatment Plant, Crateús, Ceará, Brazil

ETE CRATEUS 13 is a wastewater treatment plant located in Crateús, a municipality in the state of Ceará, Brazil. The plant serves a population of 959 and operates under Brazil's national environmental regulations, which require secondary treatment for urban wastewater. As a secondary treatment facility, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant discharges approximately 77.76 m³/day of treated effluent. The plant is situated inland, over 50 km from the coast. In Brazil, wastewater treatment plants are regulated by the National Environment Council (CONAMA) and state environmental agencies, which set discharge standards to protect water quality. The treated effluent from ETE CRATEUS 13 ultimately drains into the local watershed, contributing to the region's water resources. The plant plays a key role in protecting public health and the environment by reducing pollution loads in the semi-arid region of Ceará, where water scarcity makes water quality management particularly important.

The plant discharges into local water bodies within the Poti River basin, which flows through Ceará and Piauí before reaching the Atlantic Ocean. The semi-arid climate of the region means that water resources are limited, and maintaining water quality is critical for downstream communities and ecosystems. The treated effluent supports aquatic life and helps preserve the ecological balance of the river system.
