Three enterprises in the industrial park in Hai Duong are licensed to discharge waste directly into the environment, including Best Pacific Vietnam Co., Ltd., Tinh Loi Garment and Pacific Crystal Vietnam Textile.
These 3 companies have an average total wastewater volume of about 8,561 m³/day and night. The above companies have built wastewater treatment plants that meet QCVN 40:2011/BTNMT level A before discharging into the receiving basin, so they have been licensed by competent authorities to discharge directly into the receiving basin.
According to the Hai Duong Industrial Park Management Board, the average total volume of wastewater from secondary projects in the industrial park transferred to the general collection and treatment system is about 9,651 m³/day and night. After treatment, wastewater from industrial parks meets QCVN 40:2011/BTNMT level A standards before being discharged into the environment. In general, the quality of wastewater from secondary projects meets the transfer requirements, in accordance with the agreement between the enterprise and the industrial park investor.
Currently, Hai Duong has 17 established industrial parks, of which 11 are operating and have built wastewater treatment systems in stages, with a total design capacity of 26,470 m³/day and night, but are only operating at more than 36% of the design capacity.
All wastewater treatment plants of secondary projects in the industrial park have been installed with automatic monitoring systems, connected and transmitting data directly to the Department of Natural Resources and Environment.
