FRP Access Risers
Orenco FRP Access Risers are designed to provide access to septic tank openings, as well as watertight connections between the tank, riser, and lid. They can be installed on a concrete tank equipped with Orenco tank adapters or bonded to a fiberglass or dicyclopentadiene (DCPD) tank. They can also be used as valve enclosures.
Orenco Fiberglass Access Risers are constructed of filament-wound fiberglass to be lightweight, corrosion resistant, and extremely strong. Risers are available in 24in and 30in (600mm and 750mm) diameters, with lengths available in 3in (75mm) increments. They have four bolt catches to secure access riser lids. Optional tank shield brackets can be added for the installation of an Orenco secondary safety barrier.
