sewage treatment plant

About a quarter of the volume of wastewater entering sewage plants for treatment would not have to be treated. This is extraneous water that infiltrates decrepit sewers and blends with “genuine” wastewater. In a project, a group of experts explored how this affects water quality and how sewer rehabilitation can remedy the problem.

The waste water charge could be a viable way to help finance the upgrading of large waste water treatment plants to include a 'fourth treatment stage". A new study has determined that these facilities can reduce micropollutants – pharmaceuticals, for example – which are present in waterbodies.
