Sewerage

isic code 3700 covers the sewerage industry, which is a critical component of modern infrastructure and public health systems. This industry is responsible for the collection, treatment, and disposal of wastewater, playing a vital role in maintaining sanitation and environmental standards. The sewerage industry is closely linked to the broader water management and utilities sectors, contributing to the overall functioning of urban and industrial areas.

The main production techniques in the sewerage industry involve the use of specialized equipment and infrastructure. This includes sewer networks, pumping stations, and wastewater treatment plants. The key steps in the sewerage process are the collection of wastewater, its transportation through the sewer system, and the treatment of the collected water to remove contaminants and pollutants. Treatment methods can vary, but commonly involve physical, chemical, and biological processes to purify the water before its final discharge or reuse.

The sewerage industry requires a range of inputs, including raw materials such as pipes, pumps, and treatment chemicals. Additionally, the industry relies on specialized machinery and equipment, such as sewer cleaning vehicles, treatment plant machinery, and monitoring systems. Skilled labor, including engineers, technicians, and operators, is also a crucial input for the effective functioning of the sewerage industry.

The primary output of the sewerage industry is treated wastewater, which can be discharged into the environment or reused for various purposes, such as irrigation or industrial processes. The industry also produces byproducts, such as sewage sludge, which can be further processed and utilized, for example, in 3821 Waste treatment and disposal. The sewerage industry's outputs are essential inputs for other related industries, such as 3600 Water collection, treatment and supply.
