There are several causes for substandard urban sewage effluent. They may include improper operational practices during treatment, excessive pollutant concentrations in incoming raw sewage, or lax follow-up treatment procedures. Regardless of the root cause, one key principle remains clear: operators who discharge treated sewage directly without using Water Quality Monitors to verify that all pollutant indicators comply with standards, or who release wastewater containing unqualified parameters, shall face penalties.

Sewage treatment plants bear legal liability for discharging substandard effluent, a conclusion corroborated by both regulatory authorities and judicial precedents. This legal accountability imposes binding restrictions on operators. The risk of legal repercussions serves as a reminder against negligent operations, though some operators still act out of fluke mentality. As an old saying goes, their reckoning will come sooner or later. Accordingly, we must continuously upgrade and optimize sewage treatment technologies, strengthen environmental supervision, and rigorously implement Water Quality Testing to fulfill our respective responsibilities dutifully.

Three core points shall be clarified for all urban sewage treatment plants:

1. Neither regulatory policies nor judicial practice exempt sewage treatment plants from liability. Where substandard in fluentleads to non-compliant effluent, this factor will be taken into account during penalty assessment. While relevant provisions allow for mitigated or reduced penalties in accordance with the law, full exemption from liability is not permitted.
2. Establish a correct understanding of sewage treatment supervision. Sewage treatment facilities are transitioning from pollution treatment entities to regulated pollutant discharge entities. Competent urban sewage regulatory authorities shall shift toward proactive oversight of pollution treatment outcomes.
3. Operators and supervisory departments must conduct real-time monitoring of discharge indicators for all sewage tanks, which essentially entails comprehensive water quality testingto guarantee only fully compliant effluent is discharged. When in fluentquality exceeds thresholds, staff shall promptly activate emergency response protocols and implement targeted corrective measures.
