(Based on the Company's basic standards issued on March 23, 2020)| Criteria | Brick/Concrete Manhole | Regular Manhole |
| Economic | – The construction have many steps that take a lot of time – Need to be replace in 10-15 year – Easy to get clogged | – Quick installation time – Lifespan of product up to 50 years – Prevent drainage blockage |
| Technology | – The roughness of the pit of brick / concrete pit is large, requiring a slope to ensure flow velocity and no sedimentation – Manhole, joints, outlets are easily cracked causing leakage of sewage – Long installation due to many process | – The roughness of plastic manhole wall is almost none exsisting, limiting sediment and ensuring flow rate – Manhole are connected to plastic drain pipe, using specialized glue allowing no leakage – Fast construction time |
| Maintenance operation | – Replacing require demolish and rebuild | – Easily performing maintenance routine checks and troubleshooting |
| Environmental Protection | – Environmental protection is not good, does not prevent odors – Easy to be eroded or corroded by sewage environment – Easy to leak wastewater – Inability to prevent reflux from the public drainage system into the house during high tide or heavy rain – No collection of solid waste, waste fat. | – Protect the environment well and prevent odors thoroughly
– Manhole does not eroded or corroded by wastewater environment
– No leakage of wastewater because its closed system |
Similar to the principle of operation of traditional concrete pits
