The Jundiaí Sanitation Company in Brazil Sets a New Standard in Proactive Risk Management for Municipal Wastewater Treatment

The Jundiaí Sanitation Company (Companhia Saneamento de Jundiaí, CSJ) provides sewage treatment services for the city of Jundiaí, Brazil, treating a volume of sewage and effluent equivalent to that produced by a population of 1.6 million people. The Jundiaí River, which receives treated effluent, has been undergoing a cleanup process since the early 1990s. The progressive improvement in water quality has made its use suitable for public water supply, significantly increasing the demand for stricter monitoring and control. CSJ is evaluating LIQUM technology to monitor wastewater quality in real time at its treatment plant, with the aim of protecting biological treatment processes and ensuring compliance with environmental requirements.

Hitherto, wastewater treatment operations have primarily been managed by means of dissolved oxygen probes and laboratory analysis results, which can take several hours, making it difficult to respond quickly to changes in wastewater quality. By contrast, real-time water quality monitoring makes it possible to detect irregular industrial discharges immediately, which is especially important in a city with over 300 industrial facilities connected to the sewage network.

The irregular discharge of industrial wastewater into the sewage network poses a serious risk to wastewater treatment operations. Industrial effluents may contain inorganic substances, heavy metals, and other non-biodegradable compounds that can disrupt biological treatment processes at the wastewater treatment plant, leading to operational instability, increased costs, health impacts, and environmental risks.

Following internal assessments, with the implementation of LIQUM 6th Sense, a real-time wastewater quality monitoring system, CSJ intend to continuously monitor the quality of wastewater entering the treatment plant and immediately detect abnormal conditions. 6th Sense functions as an Early Warning system, allowing for rapid interventions before industrial discharges interfere with biological treatment or result in environmental non-compliance.

CSJ plans to expand the 6th Sense monitoring system with a special focus on controlling and monitoring the sewage network and industrial discharges. This expansion will enable the identification of industrial plants that are not compliant with the legal permits and standards for effluent discharge.

CSJ aims to position itself as the digital front-runner in advanced wastewater risk management in Brazil, setting a new standard for utilities and cities growing under industrial pressure. Real-time wastewater quality monitoring is a strategic investment in operational stability, environmental protection, public health, and the long-term sustainability of urban wastewater infrastructure. Moreover, improving the control of industrial discharges extends the lifespan of sewage networks and delivers significant cost savings through more efficient asset management.
