Orenco® PVC Access Risers provide access to tanks and components in water and wastewater systems. They can be cast into the tops of concrete tanks, bonded to a concrete or fiberglass tank with epoxy, or bolted down to a concrete tank with an adapter and bolt-down kit. In addition to providing risers, Orenco also offers riser accessories including grade rings, grade ring inserts, and riser-to-lid adapters, as well as tools for cutting risers squarely and cutting grommet holes.
Orenco strongly recommends that all tank risers 12-in. and larger in diameter be equipped with riser safety grates to help prevent accidental or unauthorized entry.
