Sewerage systems are a critical component of modern cities' basic infrastructure. If tap water pipelines are the “arteries” of the metropolis, then the sewerage system could be said to be “veins”. Household sewage and industrial effluent are collected via the sewerage system and processed at the sewage treatment plant. The water is treated to a quality level specified by the national discharge standards and then released into the environment to avoid polluting rivers, lakes and the sea. Modern sewage treatment plants have now been upgraded to water resource recycling plants, with the future trend being the reuse of treated water. This will ensure that our precious water resources can be used in a sustainable manner long into the future.
