Our preventative strategy to identify areas on construction sites that are at risk from spills of hydrocarbons and chemicals really paid off recently.
Team Van Oord (TVO), flood and coastal defence specialists, were asked by the Environment Agency to repair a leak at Green Level Pumping Station at Erith on the River Thames. TVO project and site managers identified gullies with drainage that ran into the Thames as a possible threat to the environment in the event of a spill.
On consultation, we recommended Pro-Earth Drain Covers were placed over the gullies. Our Drain Covers provide an ideal preventative solution – filled with SaveSorb, they let water pass through, while capturing contaminants like oils, diesel and chemicals.
This forward-thinking averted what could have been a major environmental incident.
Two weeks after the Drain Covers were put in place, a third-party articulated lorry left an industrial unit opposite the TVO site, and ignored signs highlighting a one-way system.
As it proceeded to drive around the system the wrong way, the lorry’s undercarriage connected with a ramp, which punctured the fuel tank and also disconnected TVO water hoses that were enabling dewatering on the site.
The contents of the fuel tank, as much as 200 litres, flooded onto the tarmac, mixed with the water being pumped out of the hoses and flowed towards the gullies protected by the Pro-Earth pads.
After the incident, testing proved that Pro-Earth Drain Covers prevented diesel entering the drainage system, and crucially, allowed ample time to manage the incident.
Not only did our Drain Covers prevent a major environmental incident, the cost of clean up of the spill was minimised.
