A bespoke solution for every access challenge
Ridgistorm-XL chambers, catchpits and manholes offer a versatile, fully configurable solution for modern drainage networks. Manufactured in-house to your exact specifications, each unit arrives ready to install, reducing programme time and ensuring consistent quality.
Our range supports diverse access and flow management needs, while Ridgistorm-XL catchpits provide effective silt and debris capture to enhance system performance and protect downstream assets.
Our in-house fabrication facility enables us to engineer fully tailored solutions for precise project requirements. From one-piece manholes and catchpits to flow control devices, treatment filters, customised fittings and specialist bends, our team delivers accurately manufactured, high quality components built to specification.
All chambers and fabricated units are produced using modern manufacturing methods and delivered to site ready for installation, reducing handling, storage and on site health and safety risks.
Each pre-fabricated solution is designed to integrate seamlessly with existing drainage and water management systems, including Ridgidrain, Ridgisewer and Ridgistorm XL, or can be engineered to connect with alternative networks.
Ridgistorm-XL chambers can be easily adapted with essential ancillary components such as guardrails, safety chains, steps, ladders, and toe holds to enhance safety, accessibility, and compliance across both temporary and permanent installations.
Additionally, Ridgistorm-XL Manholes can be manufactured with dedicated lifting points, engineered to facilitate safe handling during loading, off-loading, and installation. These features help streamline site operations while prioritising worker safety.
A simple, fixed-opening device that limits flow by forcing water through a precisely sized aperture. Reliable and cost effective, orifice plates provide predictable flow control with minimal moving parts.
A self activating unit that uses rotational flow to restrict discharge. Vortex regulators are well suited for stormwater systems requiring variable, energy efficient flow management.
A hinged flap that allows flow in one direction while preventing backflow when downstream pressure rises.
Penstocks can be manually, electrically, or hydraulically actuated and are commonly used in treatment works, flood control structures, and culverts.
Our purpose-built high-density polyethylene (HDPE) pre-fabricated catchpits are ideal for stormwater and land drainage applications and are the simplest and most cost-effective way of separating out silt and debris, providing an easily maintainable drainage system and helping to protect the downstream drainage system and local environment.
Manufactured from Ridgistorm-XL structured wall pipes, they meet the material requirements of BS EN 13476:2007 (Parts 1–3), ensuring long-term durability and regulatory compliance.
