1. Minh Tùng Composite
Website:https://minhtungcomposite.vn/
Address: 11th floor, Zen Tower, 12 Khuat Duy Tien Street, Thanh Xuan Ward
Contact: 0934 519 385 | 0965 966 268
Hours: Monday to Saturday, 7:00 AM to 5:30 PM
Minh Tùng Composite uses advanced Fiber Reinforced Plastic (FRP) and a horizontal cylindrical design to maximize holding capacity without deep digging.
With their specialized tech that handles tight ground spaces, finding a reliable wastewater setup in crowded residential areas is made easier.
I appreciate how their smart layout spreads soil pressure evenly and prevents structural warping. It’s handy when your deep excavation might threaten a neighbor’s foundation.
It’s also great that the interior has a sealed three-compartment bio-filtration setup with microbial filter balls that destroy odors and break down organic waste smoothly.
On the downside, these lightweight composite units are sensitive to ground pressure during installation. If the crew forgets to fill the tank with water before backfilling, the whole system can tilt or crack under shifting soil.
2. Đại Phát Composite
Website:https://biogascomposite.com.vn/
Address: Quyet Ha Village, Phu Nghia Commune
Contact: 0977 686 502 | [email protected]
Hours: Monday to Wednesday, 7:30 AM to 6:00 PM; Thursday, 7:30 AM to 5:00 PM; Friday to Sunday, 8:00 AM to 4:00 PM
Long-term property planning needs durable infrastructure that won’t fail after a few years of heavy use, which is why Đại Phát Composite offers a standout 60-year warranty.
They also build products using seamless single-block Compression Molding Compound (CMC) technology that meets Japanese standards.
When I spoke directly with a building supervisor using this setup, they mentioned that the leak-proof design easily handles high wastewater volumes while meeting strict environmental codes.
The treated water also meets the standards set by the Ministry of Natural Resources and Environment, giving local property managers real peace of mind.
On the downside, moving these massive pre-fabricated single-block structures through tight, winding alleys is a major logistical headache.
In some narrow spots you can’t install them without renting expensive lifting equipment, so measure your access paths carefully first.
3. Son Ha

Address: 13th Floor, Capital Place, No 29 Lieu Giai Street, Ngoc Ha Ward
Contact: 1 800 6566 | [email protected]
Hours: By appointment
When managing a major construction project, dealing with unbranded workshops can lead to big structural headaches down the road. Thankfully, Son Ha brings real corporate reliability.
For starters, they manufacture high-grade systems in accordance with the International Organization for Standardization (ISO) 9001:2015 standard.
Their premium eco-friendly tanks use multi-layer plastic structures to prevent cracking. They easily outclass traditional brick setups that leak into the soil.
Much like hiring reliable roofing contractors for critical structural work, choosing an established wastewater system provider means clear warranties and long-term accountability.
Their strong supply chain in Northern Vietnam also ensures fast delivery without shipping delays.
On the downside, these high-quality units carry a premium price that might strain smaller budgets.
Because they operate as a large multi-industry conglomerate, they also lack hyper-focused plumbing consultants, so you may need independent contractors for tricky, hands-on installation advice.
4. Môi Trường Xanh Environment Service
Website:https://thongconghutbephot.cloud/en/
Areas Served: Hanoi and nearby areas
Contact: 0962 308 861
Hours: Available 24/7
Môi Trường Xanh Environment Service uses 4K Ultra High Definition robotic cameras and powerful Japanese vacuum trucks to clear blockages without messy digging.
I tried their emergency service myself during a heavy rainstorm, and the technician arrived within 15 minutes to clear the lines cleanly through the existing vents.
They also offer flat-rate pricing that runs notably lower than traditional competitors, backed by a formal five-year written warranty.
On the downside, their setup is strictly optimized for regional boundaries, so if your property sits just outside the local district limits, their trucks can’t serve you.
Running long suction hoses down tight walkways can also block pedestrian paths and stretch out job times in dense neighborhoods.
5. TAN MY GROUP
Website:https://tanmygroup.com.vn/
Address: No. 20, Alley 67, Do Quang Street, Yen Hoa Ward
Contact: 024 3225 2752 | 024 3558 5841 | [email protected]
Hours: Monday to Sunday, 8:00 AM to 5:00 PM
Balancing space limits with strong durability is a constant challenge for modern urban townhouses. TAN MY GROUP tackles this by offering flexible vertical and horizontal smart tanks built in their local industrial zone.
Their systems use premium primary plastics that meet official health safety standards, keeping local groundwater clean and protected.
Much like hiring professional surveyors to check property boundaries before digging, choosing an established brand with over 26 years of local experience keeps your underground infrastructure safely aligned with urban demands.
Plus, their wide dealer network across the capital also makes sourcing replacement parts and technical help simple.
On the downside, their technical documentation and support are tailored almost entirely to Vietnamese speakers, which can make it tough for foreign developers or expats to coordinate directly with the corporate office.
