With a dual-source water supply system from the Nhon Trach groundwater plant and the Thien Tan water plant, Ong Keo Industrial Park offers investors complete peace of mind regarding the water resources needed for production. This is one of the standout infrastructure advantages worth considering when exploring industrial real estate in the Dong Nai region. This article analyzes in detail the water supply capacity at Ong Keo Industrial Park along with related infrastructure factors.

Overview and strategic location of Ong Keo Industrial Park
Ong Keo Industrial Park is located in Dai Phuoc Commune, Dong Nai City, with a total area of 855.6 hectares, of which the leasable industrial land area reaches 535.3 hectares, currently achieving an occupancy rate of 59%. The planning structure is reasonably allocated with industrial land accounting for 62.56%, service center 6.13%, greenery and water surface 17.32%, technical zone 1.50%, and transportation-port connection 12.49%.
The location of the industrial park lies within the southern key economic zone, part of Dong Nai province, where water supply and national grid infrastructure have been synchronously developed. Thanks to this location, water supply at Ong Keo Industrial Park is reliably maintained through strong connections to major regional water treatment plants.
Dual water supply capacity: Nhon Trach and Thien Tan
The water supply system at Ong Keo Industrial Park currently operates primarily from the Nhon Trach groundwater plant with a capacity of 20,000 m3/day, priced at VND 18,000/m3. This is the main supply source, meeting the production needs of most enterprises currently operating in the industrial park.
A notable feature in the water supply design at Ong Keo Industrial Park is the ability to supplement from the Thien Tan water plant, with a capacity of up to 200,000 m3/day. Having such a large-capacity backup source eliminates the risk of water shortages in case production demand increases or the primary source encounters issues. This is precisely why water supply at Ong Keo Industrial Park is regarded as one of the safest and most sustainable systems in the region.
Why the dual water supply model matters to investors
For industries requiring large and stable water volumes such as textile dyeing, food processing, and chemicals, having two independent water sources allows businesses to operate continuously without disruption concerns. This dual water supply model at Ong Keo Industrial Park also reduces dependency risk on a single source, a common issue faced by many other industrial parks.
Synchronized technical infrastructure supporting production
Alongside the water supply system at Ong Keo Industrial Park, the technical infrastructure here is modern and well-integrated. The internal road network ranges from 19-61m wide with 2-6 lanes, well accommodating heavy container trucks, facilitating smooth transport of raw materials and goods.
The national power grid supplies a 22KV voltage, ensuring stable electricity for industrial production activities. Telecommunications services are provided by major carriers such as VNPT, FPT, and Viettel, with fiber optic speeds up to 90MB/s, meeting digital connectivity needs for modern manufacturing.
Wastewater treatment and environmental standards
Alongside the water supply system at Ong Keo Industrial Park, the phase 1 wastewater treatment plant has a capacity of 3,000 m3/day, meeting QCVN 40:2025/BTNMT standards. The wastewater treatment fee is charged at USD 0.6/m3, with wastewater volume calculated at 80% of the water consumption volume.
This synchronized investment in both water supply and wastewater treatment demonstrates the developer’s commitment to sustainable industrial park development, meeting increasingly stringent environmental standards today.
Logistics system and internal port
A major advantage of Ong Keo Industrial Park is its internal port with a capacity of 30,000 tons, serving enterprises within the industrial park and surrounding areas. Combined with the stable water supply at Ong Keo Industrial Park, this logistics system creates a closed supply chain loop, convenient for import-export businesses.

These connections make it easy for businesses to access major consumption markets and export channels.
The combination of stable water supply at Ong Keo Industrial Park and convenient inter-regional transport networks is a key factor helping this industrial park attract an increasing number of domestic and foreign investors.
