16" x 8" Septic Tank Riser Kit

The 16" x 8" septic tank riser kit raises your septic system access point slightly above ground level, making inspections, pumping, and maintenance more convenient while keeping a low-profile appearance. This height is ideal for shallow systems or for making minor adjustments to an existing riser setup. This kit includes a 16" diameter riser, a secure cover, and all necessary installation hardware. Each component is made from heavy-duty, UV-resistant polyethylene, built to withstand long-term outdoor exposure, moisture, and soil contact without rusting or corroding. The fitted cover helps protect against water intrusion and limits unauthorized access. Key Features: 16" diameter riser with 8" height for septic tank access Heavy-duty, corrosion-resistant polyethylene construction Tight-fitting cover for added safety and protection Compatible with most standard septic tank openings (verify measurements before purchase) Includes installation hardware Installation Notes: This riser kit is suitable for both new and existing septic systems. Confirm your tank opening size and riser height requirements before ordering. Professional installation is recommended to ensure a proper seal, compliance with local codes, and long-term reliability. Routine inspections of the riser and cover will help maintain system integrity and prevent water intrusion. Note: Dimensions shown are for the kit base. This model includes a 3" safety pan with an inner diameter of 20" due to a slight bevel. Dome lids add approximately 1" to overall height. Upgrades to flat lids are available for an additional cost. Remove any existing concrete lid before installation. Please confirm diameter and height before ordering. Return shipping costs for incorrectly ordered sizes are the customer’s responsibility.
