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!
