Five Ways Plastic Manholes are Better than Other Alternative Manhole Materials

Manholes are built to help in making it simpler to exploit and maintain works of sanitation networks. While a number of manholes can be visited, the chambers have the same function and cannot be visited. They can be installed in the same place through insitu construction or with the prefabricated. The majority of manholes are made of concrete, plastic, and brick. Read on to understand how plastic manholes are different from other alternative manhole materials such as concrete and brick counterparts.

Manhole Installation

Manholes made of plastic materials are simple and easy to install. With these manholes, there is no need to use heavy machinery to transport. Also, the installation does not require many workers. This means a reduced installation cost. Meanwhile, concrete manholes require heavy machinery. For instance, a concrete manhole can have a diameter of one meter, a height of 2 meters and 2.5 tons of weight.

Response to Seismic Disturbances

Soil movements or vibrations with concrete and brick manholes can make their body break. In fact, this can also happen in the rigid join where there are pipe connections. But, plastic manholes adapt to the soil and are flexible enough to play in their favor. They demonstrate their solvency during seismic disturbances.

Resistance to the Impacts of Wastewater

Brick and concrete manholes are not resistant to the effects of wastewater which can corrode the walls because of the agents they contain. But, plastic manholes have resistance to acids, salts, and other materials present in wastewaters.

Concrete manholes don’t have walls or bottoms that can resist chemical products while their plastic versions can support chemical waste and landfills, making them the ideal choice for wastewater evacuation.

Ability to Deal with Water Infiltrations

Brick and concrete manholes may suffer water infiltration or leaks. But, plastic manholes ensure there are no leaks because of cracks and porosity. Also, they make sure there will be no water infiltration through the walls.

Maintenance

Concrete manholes are rough and this plays against them in terms of their periodic cleaning. Maintaining them can be difficult given the solid and liquid components dragged by wastewater which can stick in the manholes. But, manholes made of plastic tend to have an internal flat surface. They have a smooth surface and do not have corners. They have slopes towards the outlets that allow a good water flow. Cleaning and maintaining plastic manholes periodically will always be a breeze.
