CASE STUDY: M56 Blocked Culvert Clean

 

M56_motorway_sign_Junction_14

We’ve been doing incredible work on the M56! MEGATRON, our brilliant industry leading vacuum tanker, was on site to clear a 1000mm blocked culvert! The trash screen that was present was severely damaged and was removed for us to access the huge culvert. It ran underneath the M56, 6 lanes + hard shoulders through to a farmer’s field. The huge tunnel was approximately 8m off the M56 carriageway. This was no access issue for Megatron’s powerful suction and Hydro Cleansing’s hose. We used a cofferdam to halt the flow of water and allow the confined space team to access the blocked culvert.

6000 gallon bulk tanker removed the waste. Our fantastic confined space engineers cleared the huge culvert with extraordinary efficiency! You can’t beat our engineers for hard work and passion!

Over the past few years the silt had built up and blocked the inlet of the culvert this in turn meant that whenever it rained, it flooded the surrounding area/fields on the west bound carriageway. Hydro Cleansing cleared all the slit and debris from the blocked culvert and tipped slurry off site. The culvert is now free from debris and the stream free flowing. A new trash screen was installed.

JOB DONE!

Amazing Sewer Cleaning from Hydro Cleansing!

Sewer cleaning is something Hydro Cleansing are the go to guys for. Cleaning a London mainline sewer requires some complex logistics and expert engineers. From cranes, to penstocks, to 500m of jetting hose, this one required a specialist approach.

The sewer had to be cleared of silt in order to allow an inspection of the sewer to take place. The line was 20% full of waste and a risk assessment had established that the risk was significant enough to require all of the silt to be removed before the inspection was undertaken.

The sewer water was diverted by lowering the penstock which sent the flow of water through an alternative sewer. This penstock didn’t keep all of the water out and so the remaining storm water had to be continuously pumped away from the chamber where the engineers were working. This was 45m deep! A crane was supplied by the client to lower in the pumps and hoses.

From there our engineers could remove the silt and MEGATRON, the largest vacuum tanker in Europe, vacuumed it up the 45m into bulk tankers for disposal. MEGA REEL, the longest jetting reel available at 500m allowed the confined space engineers to jet as far into the sewer as they were required to. This loosened the silt and meant it could be sucked up the hoses at astounding speed!

The sewer cleaning was carried out during the night as the flow of waste water is lower. Without the awesome power of Megatron, the specialist hose of Mega Reel of the expertise and commitment of our engineers, this job would have taken weeks. It was completed in a few nights!

Expertise is very important in managing confined space risks

Expertise plays a very important role in a confined space

Aside being completely or partially enclosed, a confined space poses a lot of risks to people. It is believed that about 60% of confined space fatalities have been among the would-be rescue team.  The dangers or hazards that abound within a confined space are a lot more than normal workspaces.

Daniel Okrent opined that: “Right, but there’s expertise and then there’s inside information. And I think we have to make the distinction.” The Oxford dictionary defines expertise as: “an expert skill or knowledge in a particular field.” If you are regarded as an expert in a given field, it becomes apparent that you have a higher degree of knowledge or authority in the given subject matter.

In the field of confined space, the role of an expert is very crucial in ensuring the safety of workers. The experts know the confined space regulations, the risks involved, the appropriate equipment and the ability to make a quick and well-informed decision.

 

Expertise plays a very important role in a confined space

 

It is with regards to the abovementioned and the importance of expertise, that a well-trained confined space top-man, from the Hydro Cleansing team was able to upgrade a 2 man confined space team to an additional 3 man rescue team.

The task ahead was one that required a great degree of careful planning and expertise, where every little detail was important. To get into as much detail as possible, there was a tunnel with a length of about 75 metres. One of the bigger challenges was an exposed 11, 000v power line. The other issue was an overflowing sewer that had led to an aggregation of waste. The confined space team were expected to clean the sewer overflow to enable the safe repair of the power lines.

The Hydro Cleansing top-man utilised his deep understanding of health and safety legislation, to make the important decisions that helped this job end in success. The top-man utilised his expertise to make the confined space refined or cleared for the repair of the power line.
