Sandfield Penstock Solutions provide site specific solutions to water pollution containment drawing on our in-depth, specialist knowledge of the latest regulations and technology for water pollution containment, flood management and firewater control. Sandfield Penstock Solutions are pioneers in the design and manufacture of purpose designed water pollution containment devices which are solar powered, connected to the GSM network for remote and automated activation and modular in design to fit into existing drainage systems and infrastructure with a minimum of cost and disruption. Sandfield Penstock Solutions  continue to invest in developing real time monitoring, reporting systems and new ways of triggering our devices in the event of a pollution incident to ensure that the systems that we provide remain future proof and provide our customers with the very best protection against the risk of causing water pollution.

In recent years corporate responsibility and accountability for the environment has grown. It is now a crime to cause water pollution punishable with considerable fines, clean up costs and in the most extreme or negligent cases imprisonment. Our belief is that no business would knowingly damage its reputation and lose time and money repairing the environment from a pollution event that could have been prevented. Our mission is to provide businesses with the most affordable advice and solutions to remove the cost and disruption barrier to preventing water pollution. We understand that all businesses operate with a host of risks, Sandfield Penstock Solutions are here to support you to understand your specific risk and work with you to implement the most cost effective, non-disruptive solution. Failure to understand the potential of water or ground pollution from a spill, flood or fire is a huge, avoidable mistake that many companies make every year.

If spill containment and CIRIA c736 compliance is currently a consideration for you please do not hesitate to call 0330 223 4372 or email us, we will be very happy to discuss our solutions with you.

“Our mission is to eliminate all pollution from industrial spills and fires by listening to our customers and supporting them to exceed their environmental expectations.”
