How are the problems being managed 1. Higher sewage treatment charges – these mean that factories try to cut down on the amount sewage waste they are pumping out as it costs them a lotto get rid of it. They rethink their industrial processes and see where they can cut down on or reuse their waste. The amount of water pollution is reduced. 2. Stricter pollution regulations on factories – factories have to install better technology to ensure that any gases they release into the air meet air quality standards, so this reduces the amount of air pollution.
