What is Municipal Wastewater Treatment?

Urban wastewater is defined as the mixture of domestic wastewater from kitchens, bathrooms and toilets along with rainwater runoff from roads, rooftops and other impermeable surfaces such as pavements. This water-based waste is more generally referred to as sewage. Municipal wastewater treatment is used to process this raw sewage in order to remove contaminants and enable the purified water to be returned to the environment.

Sewage Treatment Technologies

Veolia provides customised effluent treatment systems encompassing all stages of the wastewater and sewage treatment cycle. Sewage treatment technologies include clarification, filtering, separation and aerobic wastewater treatment. These technologies are in effective use across various wastewater treatment works throughout the UK, ensuring high-quality sewage treatment and compliance with stringent standards.

Why Sewage Treatment is Important

Here are some of the key reasons why sewage treatment is important:

  • Populations are expanding, resulting in increases in sewage volume and loads on wastewater treatment plants
  • Pollutants in stormwater runoff include nutrients (from lawn and land fertilizer), bacteria, pesticides, petroleum by-products and metals
  • Without appropriate treatment, raw sewage would damage the water environment, cause public health problems and adversely affect wildlife
