16" x 5" Septic Tank Riser Kit

The 16" x 5" septic tank riser kit is a compact solution for raising your septic system access point slightly above ground level. This low-profile riser is ideal for shallow installations or when only a small increase in height is needed for easier access to the tank.

This kit includes a 16" diameter riser, a secure cover, and all necessary hardware for installation. Each component is made from heavy-duty, UV-resistant polyethylene, built to withstand outdoor exposure, moisture, and soil contact without corroding. The fitted cover provides a secure seal to help prevent water intrusion and limit unauthorized access.

Key Features:

• 16" diameter riser with 5" height for septic tank access

• Heavy-duty, UV-resistant polyethylene construction

• Tight-fitting cover for safety and protection

• Compatible with most standard septic tank openings (verify dimensions before purchase)

• Includes installation hardware

Installation Notes:
This riser kit can be used for new or existing septic systems. Always confirm your tank opening size and required riser height 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 performance.

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.
