Sewer refers to a system of underground pipes and structures designed to carry wastewater, including human waste, from buildings and industrial facilities to treatment plants or disposal areas. Proper sewer systems play a critical role in maintaining public health, preventing water pollution, and promoting sanitation.There are different types of sewer systems, including:
Sanitary Sewers: These sewer systems carry domestic wastewater from sinks, toilets, showers, and other indoor plumbing fixtures to treatment plants for purification.Storm Sewers: Storm sewers are designed to manage rainwater runoff, preventing flooding and directing the water to nearby water bodies or underground drainage systems.Combined Sewers: In older urban areas, combined sewers collect both wastewater and stormwater in the same pipe system. The combined flow is directed to treatment plants or released into natural water bodies.Industrial Sewers: Industrial sewer systems carry wastewater from industrial processes to treatment facilities that can handle specific industrial contaminants.Each type of sewer system requires careful planning, design, and maintenance to ensure efficient and safe wastewater management while protecting the environment and public health.
