Wastewater Monitoring System - Legal Compliance and Cost Optimization for Businesses

 

After treatment, wastewater from factories and production facilities is often discharged directly into the environment, leading to serious pollution incidents. Periodic monitoring cannot comprehensively and promptly evaluate the causes of pollution, making it difficult to address and control environmental issues. An automatic, continuous monitoring system is necessary to ensure wastewater quality, comply with legal regulations, and protect the company's reputation.

1. Why Install an Automatic Continuous Wastewater Monitoring System? 

After treatment, wastewater from factories and production facilities is often discharged directly into the environment. This has caused serious environmental incidents if not continuously monitored. Periodic monitoring cannot comprehensively assess and accurately determine the causes of pollution, leading to difficulties in thoroughly addressing environmental problems. This not only hinders regulatory agencies but also affects the company's reputation. Therefore, the Ministry of Natural Resources and Environment has mandated the installation of automatic continuous wastewater monitoring stations to control the quality of wastewater discharged into the environment.

2. Who Must Install Automatic Continuous Wastewater Monitoring Stations? 

According to Clause 20, Article 3, Decree 40/2019/ND-CP (amending Article 39, Decree 38/2015/ND-CP), the following entities must install automatic continuous wastewater monitoring stations: 

  • Industrial parks, facilities within industrial parks exempted from connecting to centralized wastewater treatment systems. 
  • Production, business, and service establishments at risk of causing environmental pollution as per Appendix IIa, Section I of this Decree, with a discharge scale of 500 m3/day or more. 
  • Hazardous waste treatment facilities, centralized solid waste treatment facilities at provincial levels, and facilities using imported scrap as production materials generating industrial wastewater. 
  • Production, business, and service establishments not belonging to the above entities but with a discharge scale of 1,000 m3/day or more.
