Series 300 Stormwater Pit Riser

This 300 mm stormwater pit riser provides a practical way to increase the depth of an existing pit to suit site-specific requirements. Made from durable recycled polymer, it resists environmental exposure such as soil and moisture while remaining lightweight for easier handling and onsite installation. Designed to integrate with standard stormwater pit cases, this riser is ideal for adjusting pit depth in residential and commercial drainage projects, helping tailor stormwater systems to varying site conditions without complex modifications.
