With environmental protection requirements being increasingly tightened, investing in and completing wastewater treatment systems has become mandatory for manufacturing, business, and service facilities. However, over time of operation, or when there are changes in scale, technology, and legal regulations, many existing wastewater treatment systems no longer fully meet practical requirements. Therefore, adding wastewater treatment works becomes a necessary solution to improve treatment efficiency, ensure effluent meets standards, and minimize negative impacts on the environment.
Adding wastewater treatment works means constructing or installing additional wastewater collection and treatment systems to ensure wastewater is treated to meet standards before being discharged into the environment. This helps reduce water pollution, protect ecosystems, and safeguard public health. At the same time, adding wastewater treatment works helps manufacturing and business facilities comply with legal requirements on environmental protection. This is also a necessary measure when expanding scale, changing technology, or when the existing system no longer meets requirements.
Relevant legal regulations:
Adding wastewater treatment works means constructing or installing additional components to meet standards before discharge into the environment
Cases that require adding wastewater treatment works commonly arise during operation, expansion, or changes in operating conditions of a facility. Properly assessing these situations helps ensure the treatment system always meets technical and legal requirements on environmental protection. Below are typical situations where adding wastewater treatment works should be considered.
Detailed work items for adding wastewater treatment works should be implemented step by step to ensure synchronization, effectiveness, and suitability to the actual conditions of each system. Each work item plays an important role in enhancing treatment capacity and meeting environmental requirements. Below are the main contents in the process of adding wastewater treatment works.
Detailed work items for adding wastewater treatment works need to be implemented step by step to ensure synchronization and effectiveness
First, the executing unit reviews the overall area planned for construction, including available space, foundation conditions, and drainage capacity. In parallel, the purpose of adding works is clarified, such as capacity expansion or treatment technology changes. Wastewater samples at different times are collected and analyzed to evaluate pollutant loads. Survey results are an important basis for determining the scale and type of works to be added.
Based on survey results, a detailed design dossier is prepared to specify the construction plan. The design includes site layout, structural design, waterproofing solutions, and measures to ensure long-term durability. Piping systems for water conveyance, sludge collection, and air release are arranged logically to facilitate operation. In addition, the volume of each tank is calculated to match flow rate and required treatment time.
In this step, the additional treatment capacity required is clearly determined to select appropriate technology. Additional treatment items are proposed to match wastewater characteristics and discharge objectives. The design plan also considers connectivity and integration with the existing system to ensure continuous operation. Construction location is calculated to optimize space and investment cost.
The construction plan is developed in detail regarding schedule, manpower, and equipment to be mobilized. Construction and installation materials are listed to control quality and cost. At the same time, estimated investment cost is calculated to support management and approval. If construction affects operation, a temporary wastewater treatment plan is also prepared.
Construction includes building treatment tanks, installing piping systems, and auxiliary structures. Electromechanical equipment such as pumps, blowers, and control cabinets are installed according to the design. After that, new items are connected to the old system to ensure synchronized operation. Quality supervision is carried out throughout the construction process.
After installation is completed, each process stage is checked individually to detect errors. The system is test-run under no-load and load conditions to evaluate actual operational capability. Technical parameters are gradually adjusted to achieve optimal treatment efficiency. Trial operation results are the basis for confirming the system meets the set requirements.
The final stage is preparing as-built documentation fully reflecting the project’s status after renovation and additions. The contractor provides detailed guidance on operation and maintenance procedures to the managing party. Treatment technology is transferred along with necessary technical documents. At the same time, treatment performance reports and wastewater quality testing results are prepared for acceptance procedures.
Adding wastewater treatment works is not only a technical requirement but also a legal and social responsibility of every wastewater-generating facility. This process must be carried out methodically—from site survey, design, construction, to operation and handover—to ensure long-term synchronization and effectiveness of the system.
