A drainage system requires constant maintenance, especially during the rainy season. When homes experience storms and kinds of extreme weather, there is always a likelihood that mud and dirt will be washed into a drainage system before drying up and creating clogs. When mud clogs a drainage system, not only does it affect the flow of water, but also its purity. If the problem is left untreated, the clog will continue to build until serious repair or pipe replacement will become necessary. Pipe replacement is a long and arduous process, and will almost certainly be hugely expensive.
