Company Information



Spillage, firewater, and flood containment technology, also known as drain closure valves for the oil, chemical, and sewage industries.


Our range of drain closure valves includes the Flapstopper family and Telestopper. The Flapstopper is an emergency drain closure valve that prevents any pollution or firewater from leaving the site by sealing your drainage.  Once the incident/spill has passed, you can pump out the contamination and reopen the Flapstopper allowing normal flow to resume.


The Telestopper is a temporary drain closure bladder unit that is activated by manual operation and designed for emergency incidents in order to contain pollutants, firewater runoff challenges, and oil spills on site.


EIL was established in 2007 with the mission to combat aquatic pollution and control plastics in the oceans through our smart sensing technology & IoT+ platform. We strive to prioritise cost-efficiency as a top priority, understanding real business aims and goals to achieve results, whilst considering cost control a key objective.


With over 20+ years of prior industry experience, years of research & development, and a successful track record of product deployments for some of the world’s leading brands, this has enabled EIL to offer bespoke solutions to suit all site conditions and specifications.
