Clarus Environmental’s economy riser systems are injection-molded and exceptionally strong.  They are composed of HDPE, which is non-corrodible in the septic environment.  The risers are available in 6” (15 cm) lifts and can be stacked to fit any application.  12”, 20”, and 24” (30 cm, 51 cm, and 61 cm) diameter risers and covers are available.  24” (61 cm) diameter riser pans and adapter rings are also available.  The 24” (61 cm) riser pan fits anywhere in the riser stack.    A handle is included with the riser pan kit, so it can be cast into a concrete lid.  Stainless steel screws are provided as part of the hardware pack.

  • May be cast in place

  • Riser has cutouts for pipe penetration

CONTRACTOR must furnish a Clarus Environmental Septic Tank Riser, model 5083, to bring all tank access openings to grade. A 12" diameter riser will be used over the inlet baffle and a 24" diameter riser will be used over the outlet baffle. The seam between the tank and riser must be watertight. The riser is attached to the tank by casting-in place or using a Clarus model 5086-0004 24" diameter Tank Adapter as an equal alternate mounting option. The riser and lid combination must be able to withstand a 10" vacuum test. The riser must be adjustable in the field by use of 6" tall riser extensions. Concrete risers should not be considered equal. The lid must have a green finish for blending into the landscape. Lid shall have a watertight connection to the riser pipe via a molded-in gasket. Properly sized stainless steel screws must be supplied with the riser system. For additional security a Clarus Riser Pan, model 5086-0003 must be installed with a concrete lid on all 24" diameter openings.
