Until a few years ago, concrete ockpits or concrete manholes were the most used, while today it is preferred to use plastic manholes. The advantages of PP pluvial cockpits are:
- Easy to transport thanks to their lightness
- Affordability
- Easy installation and reduced installation times;
- Ecological sustainability through recycling of used materials
- Resistance to acid exposure and mechanical stress
- Easier to solve problems in case of errors during installation than concrete
