Sewerage

isic code 37, 'Sewerage', encompasses the collection, treatment, and disposal of sewage and other waste water. This industry plays a crucial role in maintaining public health and environmental sustainability by managing the waste generated by households, businesses, and other organizations. Sewerage systems are a fundamental part of modern infrastructure, ensuring the proper management of wastewater and its safe return to the environment.

The main production techniques used in the sewerage industry involve the collection, transportation, and treatment of wastewater. This typically includes the use of sewer networks, pumping stations, and wastewater treatment plants. Treatment processes may involve physical, chemical, and biological methods to remove contaminants and purify the water before its discharge or reuse.

The sewerage industry requires a range of inputs, including the wastewater itself, which is the primary raw material. Other key inputs include energy sources (e.g., electricity, natural gas) to power the treatment facilities, chemicals (e.g., coagulants, disinfectants) for the treatment process, and specialized equipment and machinery (e.g., pumps, filters, aeration systems) to facilitate the collection, transportation, and treatment of the wastewater.

The main outputs of the sewerage industry are the treated wastewater and any byproducts generated during the treatment process, such as sludge. The treated wastewater may be discharged into the environment or, in some cases, reused for various purposes, such as irrigation or industrial processes. The sewerage industry's outputs can be consumed by other industries, such as 38 Water collection, treatment and supply and 39 Waste collection, treatment and disposal activities; materials recovery.
