Some people might not believe that manholes can get clogged because of their immense width. The Youtube video “After Cleaning Five Manholes, The Vacuum Truck Also Had to Be Cleaned – Drain Water Jetter” shows what workers have to do after manhole cleaning. Let’s find out more!
The best way to clean a manhole is to use a power vacuum truck to pull the debris and residue out. However, once a service is done cleaning several manholes, they’ll have to wash the actual vacuum, which accumulates all that dirt.
Normally, the truck comes with a hose so it can be done easily.
Using the strength of the water hose, an employee must start pulling off all the remains in the vacuum. Luckily, many trucks can lift the vacuum cylinder a few degrees so that gravity can help expel the dirt. You might be surprised by the amount of mud that can collect after a few cleanings, so it’s important to be thorough while washing the vacuum truck. Once the worker in the video was done cleaning the interior, he moved on to washing the entire truck.
