Thanks to the professionalism, strong technical expertise, and tireless efforts of our entire team, Koastal Eco Group has once again been entrusted by TH True Milk Group to undertake the role of Main Contractor for two major wastewater treatment projects:
- Wastewater Treatment Plant for Dairy Farm Cluster No. 1 – capacity for 6,500 dairy cows;
- Wastewater Treatment Plant for Dairy Farm Cluster No. 2 – capacity for 5,300 dairy cows.
Both projects are located within TH Group’s large-scale, high-tech centralized dairy farming complex, recognized as one of the largest of its kind in Asia.
This continued appointment is a clear testament to the strong trust that TH True Milk places in the technical capabilities, experience, and project execution capacity of Koastal Eco Group.
TH Group’s high-tech centralized dairy farming complex is located in Nghia Dan, Nghe An Province, covering vast areas of fertile red basalt soil. The complex is regarded as a model dairy farming operation, applying some of the most modern and advanced technologies currently available in dairy farming and agricultural production.
The total herd under management and milk production is approaching 70,000 cows. Each TH dairy cow produces an average of approximately 34 liters of fresh milk per day, equivalent to more than 10,000 liters per lactation cycle — among the highest productivity levels in Southeast Asia.
Previously, Koastal Eco Group had also been entrusted with the construction of three other wastewater treatment systems for TH Group in Nghe An, Thanh Hoa, and Phu Yen.
Among them, the Wastewater Treatment System for Dairy Farm Cluster No. 3 in Nghe An, with a capacity of 3,200 dairy cows, was successfully completed, handed over, and commissioned in 2021. The treated effluent achieved Column A requirements under QCVN 62, meeting the particularly stringent requirements set by TH Group.
Through being continuously selected and appointed by leading Investors to undertake technically challenging, large-scale projects — with a value of more than VND 100 billion per system — Koastal Eco Group has demonstrated its strong technological expertise and proven capability in executing large and complex wastewater treatment projects.
These achievements also reinforce the strong reputation and credibility of the “Koastal Eco” brand in Vietnam’s wastewater treatment industry.
Koastal Eco sincerely thanks TH True Milk and all our valued customers for continuing to place their trust in us as a reliable partner in environmental protection.
We would also like to thank the entire Koastal Team for your unwavering efforts, dedication, and focus in fulfilling our commitments to our valued Investors. Together, we will continue to strengthen and develop the “Koastal Eco” brand sustainably, making it a trusted first choice for our customers.
