Pollution containment package

It is supported by a full design, commissioning and maintenance service from Hydro International's specialist Water Pollution Management team.

Toggleblok is installed on a series of UK sites, and is helping facility owners prevent damaging surface water pollution incidents. The Toggleblok valve was invented by David Cole, Hydro International’s consultancy division water pollution manager, and developed for manufacture by Sandfield Engineering. 

David Cole said: "The Toggleblok is a water-tight and failsafe valve for pollution, flood water or spill containment and the only valve we would recommend for organisations obliged to comply with UK environmental protection regulations, according to the CIRIA 736 industry standard guidance."

Pollution containment is critical for sites operating under the Control of Major Accidents and Hazards (COMAH) 2015 or Environmental Permitting (England and Wales) Regulations (EPR) 2010. It should also be integral to any compliant Environmental Management System (EMS) – or for those companies working to IS0 14001.

The Toggleblok is a retrofittable drop seal valve that protects receiving water courses by blocking the release of flood water, polluted or fire fighting water from a site’s storm drains. The Toggleblok valve’s mechanically locking failsafe design ensures the valve remains fully closed and sealed once activated until it is safely unlocked by an operator. Manufactured from stainless steel, it is factory pressure tested to ensure zero leakage to up to 0.5 bar pressure. 

 The valve can be closed remotely by means of bi-directional radio control or cloud-based communications systems.  It can also be activated automatically via a site’s fire alarm or Building Management System. Operated by a pneumatic power source, the valve is safe to use in a confined space or explosive atmosphere.
