HDPE Manholes – Straight passage manholes
Manholes are essential components in sanitary sewer systems, serving key functions such as inspection, ventilation, flow control, and direction changes. Constructed entirely from high-density polyethylene (HDPE), they are supplied with appropriate top covers, with the option for concrete tops when required. To enable routine inspection and maintenance, manholes are strategically positioned at pipe bends, junctions, diameter transitions, and branch connections. Manufactured from the same HDPE material as the pipes, these manholes are joined to the system using compatible jointing methods. This ensures a fully integrated and homogeneous piping network with consistent material properties throughout.


Tangential manholes
The main advantages of the tangential manhole include its sustainable, flexible, lightweight, inspection-friendly, self-cleaning, durable, and cost-effective construction.
