The answer to this question depends on the specific context in which urban and industrial development is taking place. However, in general, these sectors often practice improper and mismanaged sewage systems due to a lack of understanding or awareness of the potential environmental impacts of their activities.
Urban and Industrial development:
An agrarian economy becomes a manufacturing economy through the process of industrialization. Manual and specialised employees are replaced by assembly lines and mass production. In the past, this process has sparked urbanisation by generating economic expansion and employment possibilities that entice people to live in cities.
When one or more factories are built in an area, urbanisation usually starts since there is a great need for factory workers. The factories are subsequently followed by other enterprises, like those that produce buildings, sell goods online, and offer services to consumers. As a result, there are more occupations created and housing needs are increased, creating an urban area.
In many cases, engineers and other technical professionals are present in these sectors but are not consulted or involved in the decision-making process regarding sewage systems. This can lead to a situation in which the systems are not designed or operated in an environmentally sustainable manner.
