Attribute	Sewer	Sewerage
Definition	Underground pipe or tunnel system for carrying away sewage	System of pipes, pumps, and other equipment used for the collection and treatment of sewage
Function	Transport sewage from buildings to treatment facilities	Collect, transport, and treat sewage to prevent environmental pollution
Components	Pipes, manholes, and maintenance holes	Pipes, pumps, treatment plants, and monitoring equipment
Ownership	Usually owned and maintained by local government or utility companies	Owned and operated by local government or utility companies

Definition

Sewer and sewerage are two terms that are often used interchangeably, but they actually refer to different things. A sewer is a pipe or system of pipes that carries sewage or stormwater away from a building or area. On the other hand, sewerage refers to the entire system of pipes, pumps, and treatment plants that collect and treat sewage before it is discharged back into the environment.

Function

The main function of a sewer is to transport wastewater and stormwater away from buildings and homes to a treatment facility or a discharge point. Sewers are typically underground and are designed to prevent the contamination of water sources and the spread of disease. Sewerage, on the other hand, includes not only the sewer pipes but also the treatment plants and other infrastructure needed to process and treat sewage before it is released back into the environment.

Components

A sewer system is made up of a network of pipes that connect individual buildings to a main sewer line. These pipes are typically made of materials such as PVC, concrete, or clay. Sewerage systems, on the other hand, include not only the sewer pipes but also pumping stations, treatment plants, and other infrastructure needed to collect, treat, and dispose of sewage in an environmentally safe manner.

Maintenance

Maintaining a sewer system involves regular inspections, cleaning, and repairs to ensure that the pipes are functioning properly and not clogged or damaged. Sewerage systems require even more maintenance, as treatment plants and other infrastructure must be constantly monitored and upgraded to meet environmental regulations and ensure the safe disposal of sewage.

Environmental Impact

Sewers can have a significant impact on the environment if they are not properly maintained or if they leak or overflow. Raw sewage can contaminate water sources, harm aquatic life, and spread disease. Sewerage systems, on the other hand, are designed to treat sewage before it is released back into the environment, reducing the impact on water quality and public health.

Cost

Building and maintaining a sewer system can be expensive, as it requires the installation of pipes, pumps, and other infrastructure. Sewerage systems are even more costly, as treatment plants and other facilities must be built and operated to ensure that sewage is properly treated before being discharged. The cost of sewerage is often passed on to consumers through utility bills or taxes.

Regulation

Sewer systems are typically regulated by local or state governments to ensure that they meet health and environmental standards. Sewerage systems are subject to even more stringent regulations, as they must comply with federal laws such as the Clean Water Act, which sets standards for the treatment and discharge of sewage. Violations of these regulations can result in fines or other penalties.

Conclusion

In conclusion, while sewer and sewerage are related concepts, they refer to different aspects of wastewater management. Sewers are the pipes that carry sewage away from buildings, while sewerage includes the entire system of pipes, treatment plants, and other infrastructure needed to collect, treat, and dispose of sewage in an environmentally safe manner. Both sewer and sewerage systems play a crucial role in protecting public health and the environment, but sewerage systems are more complex and costly to build and maintain.
