Megatron and HCL Clear Hundreds of Tonnes of Silt

236 tonnes of waste was cleared by Megatron and team.

As well as our beast Megatron, Jack the Giant Slayer, a second articulated bulk tanker, a standard bulk tanker, the 2 man confined space team, a jet vac tanker and a welfare unit all worked on the large job.

 

Fleet A13

 

A large water filled Cofferdam was put in place to stop the river water from flowing through the culvert. We supplied the cofferdam for free. There is a baffle within the dam creating 2 chambers which maintain its stability.

 

Cofferdam

 

This unsightly black bag makes minimal impact on the environment. It uses the properties of water to hold back the river water. It is simply emptied and removed when the job is complete.

The river which runs through the culvert, under the A13, supports the RSPB Reserve at Rainham Marshes. Having been an MOD firing range for several decades it was converted into the nature reserve in 2000. The area is only 6ft above sea level and could easily flood, endangering the birds.

With the dam in place, the confined space team beavered away clearing the monumental amount of waste into Megatron’s vacuum.

The bulks were filled alternately and took the waste away for disposal, allowing the beast to work continuously.

Job done

 

Sucking at 6000+ cubic feet per minute, Megatron is Europe’s leading vacuum tanker. This raw power from the tankers and engineers allowed this job to be completed in five days!
