A sewer access pit like the name says is a pit, built to access a sewer, it was excavate and it is used to protect traps. They also must have a cover. the cover is made of steal plates, if you see an open pit be sure to call the city or inform a police officer since pits are dangerous if left open to the public.
We must dig this holes however to get to the pipes and fix them, but if our works goes for more than a couple of days, then we use our own steal plates, they are super heavy and they can cover the pits we dig, nicely. We always make sure our pits are covered since we can get in trouble if we do not do it, like sanctions and lawsuits, our team are experts and they know what they are doing, in another post we said that our headman is considered a veteran with 30 years of experience under his belt and like we have said before sewer access pit are very important and so the person who is hiring your sewer access pit excavator must hire our excavators since they know how to get the job done.
