Description
This Extension Riser is designed specifically for use with below-ground water storage tanks and rainwater harvesting systems, allowing you to raise the access height of your tank to meet ground level or finished surface requirements. It provides a practical solution when additional height is needed due to landscaping, paving, driveway installations or changes to ground levels.
Each riser can be easily cut down on-site to achieve the exact finishing height required, ensuring a neat, professional fit, whether the system is being installed in domestic gardens, commercial properties or industrial sites. For deeper installations, multiple risers can be stacked together to create the necessary access column without compromising structural integrity.
Manufactured from durable, heavy-duty materials, this extension riser is built to withstand ground pressure and environmental exposure, making it ideal for long-term use with underground water storage tanks and rainwater harvesting systems.
Perfect for ensuring safe, accessible maintenance access to your tank system, this riser helps simplify inspections, servicing and filter access while keeping your installation compliant and visually discreet.
