Engineering options that can prevent sewer overflows: With industry forced to apologise for dumping untreated sewage into rivers, changes upstream including smarter sewers would help.

The article discusses the issue of sewage discharge into the environment. It explores engineering solutions to prevent sewer overflows, including treating existing combined sewer overflows (CSOs), increasing wastewater treatment capacity, implementing smart sewer technologies for real-time monitoring, and reducing stormwater inputs through upstream measures like separation and capturing.
