Sanitary sewers are underground pipes designed to transport wastewater from homes, businesses, and industries to treatment facilities. This system helps prevent pollution and protects public health by ensuring that sewage is safely removed from populated areas. The wastewater typically includes water from sinks, toilets, and showers, which is collected and directed through a network of pipes. Once the wastewater reaches a treatment facility, it undergoes various processes to remove contaminants before being released back into the environment. Proper maintenance of sanitary sewers is essential to prevent blockages and overflows, which can lead to environmental hazards and health risks for communities.
