There are many things that go into the process of fixing a blocked drain. First and foremost is identifying the issue. This can be done by inspecting the drains for any signs of obstruction or damage. Once an issue has been identified, it is then necessary to determine what caused it. This may involve looking at past events or using technology such as closed-circuit television (CCTV) cameras to see how people and animals have interacted with the drainage system in question over time.[1] After determining what caused the blockage, steps must be taken to correct it. In some cases this may simply mean clearing away debris blocking access to the drain; in others it might require more extensive work including installing new pipes or even completely replacing a section of drainage system.[2] Regardless of its severity, all blocked drains should be fixed as soon as possible so that water does not accumulate inside plumbing systems and cause further damage[3].

With mining came heavy industrialization which led directly to increased levels of pollution within both air [11],[12],[13]]and water supplies [14],[15],[16]; however despite these challenges , Ashton Under Lyne continued rapidly expanding through much economic turbulence up until recent years when deindustrialisation began taking hold once again .
