Shafts are used in wastewater systems for gravity drainage from households, rainwater and wastewater from industrial plants. Inspection shafts allow ventilation, cleaning, maintenance, and access to sewage pipes. The most common ones are semi prefabricated circular shafts, which are extremely waterproof, light weight and easy to install, but also very affordable. Regeneracija in its broad product line program offers a choice of many different types and special design inspection shafts.

Shafts are vertical pipes with pipe connections from the sewage system at the bottom and the inlet with a lid on top. Pipe connection at the bottom goes to the dam, which directs the flow of water and prevents the deposition of silt on the bottom of the shaft.

Inspection shafts can be applied as a transit or non-transit. When installing shafts made of polymeric materials there are no restrictions. On the lawns and areas intended for pedestrians and cyclists non-transit shafts are installed. These shafts have less load and lid with a concrete ring. Transit area shafts can endure axial loads of 600 KN (transit area of the cars and the heaviest trucks), or airport shafts up to 900 KN. Cover and relief ring on the top of the pane transfer load of the vehicles to the bulk material by the shaft.
