4. Sewer network A sewer network, also known as a wastewater collection system, is a network of pipes, pumps, and other infrastructure designed to collect, transport, and treat wastewater and sewage from households, businesses, and industries. The sewer network plays a crucial role in public health and environmental protection by: Collecting wastewater from sinks, toilets, showers, and appliances Transporting wastewater to treatment plants or other disposal sites Preventing sewage backups and overflows Protecting waterways and groundwater from pollution The sewer network typically consists of: Sewer pipes Manholes and access points Pump stations and lift stations Treatment plants and disposal sites

5. Storm network A stormwater network, also known as a storm drainage system, is an infrastructure designed to manage and transport rainwater and stormwater runoff from urban areas, streets, roofs, and other impervious surfaces. The network collects and conveys stormwater to prevent flooding, erosion, and pollution, and typically consists of: Storm drains (catch basins, grates, and curb inlets) Storm sewers (pipes and tunnels) Manholes and access points Stormwater management ponds, lakes, or wetlands Channels, ditches, and culverts The stormwater network serves several purposes: Flood control: Reduces the risk of flooding and property damage Water quality protection: Prevents pollutants and sediments from entering waterways Erosion control: Protects streams, rivers, and lakes from erosion and sedimentation Groundwater recharge: Allows stormwater to infiltrate the soil and recharge aquifers Effective stormwater management is crucial for maintaining public safety, protecting the environment, and ensuring sustainable urban development.
