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.

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!

 

A Grand Day Out – Thorough work from our tankers and team

Our tankers were up to some awesome team work yesterday!

Again we were out protecting our country’s motorways. The job was to clear a culvert of a build-up of embedded silt. The estimate was 30 tonnes of waste!

This was a large scale job involving a fantastic team and some of our flagship tankers. Our Super combination unit Rainmaker was there providing the hard core power for the operation. Our artic tanker which is nick named ‘Jack the giant slayer’ stored the waste that Rainmaker vacuumed. Another bulk tanker, our confined space team and a welfare unit made up the rest of the fleet.

Due to the nature of the waste, our team implemented a strategy of lowering the flow of water through the culvert to allow the confined space engineers into the space to shovel the shingle and silt into Rainmaker’s vacuum. They made a dam at the far end of the culvert and our combination unit was used to divert the remaining water flow from the culvert into a ditch beyond. It would naturally have flowed there from the culvert.

A 4” vacuum hose maintained the low water level allowing the confined space team access to the culvert. The larger 6”  hose removed the large pieces of silt.

Our confined space engineers worked flat out to funnel the silt into the vacuum hose. You can see some of the silt is the size of golf balls. The vacuum hose sucked them away into our tankers.

These guys have no need of a gym! They are up for the hard graft.

Thankfully we have a welfare unit that we bring to these kinds of jobs. A warm kitchen, toilet and shower mean our engineers can have a short break on site and return to their work without much disruption. It saves driving covered in mud to the nearest greasy spoon for a cup of tea after shovelling mud for hours.

Good honest work was done! Preventative action against flooding was taken. Our work made the light at the end of the tunnel possible.

Culvert Cleaning: Prevention over cure every time!

We’ve completed some preventative work on the M25 today. Megatron has been showing its power.

The issue was an almost blocked culvert between two large balancing ponds that went under the M25. The culvert was full of multiple kinds of waste.  It must have created a stench as well as endangering the M25 with potential flooding. With access away from the hard shoulder, our vehicles were able to park safely and our engineers, in full PPE, were able to tackle the job directly.

Our engineers who were wearing chest waders and full PPE set to work. Firstly, the engineers set up sandbags to absorb the excess silt leaving the pipe on one side. They removed the grate, clearing away the larger rubbish, the plastic gloves, crisp packets etc.

Once the Culvert was clear enough, we could bring in the jetting and vacuuming equipment. Then our powerful tankers got to work!  Our Megatron super vacuum tanker handled this job adeptly. One of our 4000 litre tankers supplied the water.

The epic jetting and vacuuming happened:

The pressure was incredible! It’s easy to look at jetting and expect it to be that impressive. That this power comes from two tankers working together to provide sufficient water flow and pressure is a remarkable feat of engineering.

Once completed, our CCTV Survey operators send in the remote control camera to check for any remaining blockages and any damage that the culvert may have. Once we have established that all is well; our tankers return the waste to our site for full disposal.

The waste will be disposed of on our site. The waste disposal unit at Hydro Cleansing recycles up to 99% of the waste we take in. It is sieved and pressed and sieved and pressed until the waste is so fully compacted that it can safely be sent to landfill.

We came, we saw, we jetted, we checked, we documented!

It’s a thorough and powerful job from Hydro Cleansing. If you have a similar issue, give us a call.

24 hours a day, 7 days a week, 365 days a year.

Our engineers do work shifts but Hydro Cleansing and our spectacular tankers are always working.
