Sewage Treatment

Sewage Treatment Goals

• The main goal of sewage treatment is to remove contaminants and pollutants from wastewater, producing a treated effluent that is safe to release into the environment.

Decentralized vs Centralized Sewage Treatment

• Decentralized sewage treatment systems involve small-scale, on-site treatment of wastewater, often used in rural or remote areas where connection to a centralized system is not feasible.
• Centralized sewage treatment systems, on the other hand, involve large-scale, community-based treatment of wastewater, often serving entire cities or towns.

Stormwater and Sewage Treatment

• Stormwater is rainwater or snowmelt that runs off surfaces, such as roads, rooftops, and sidewalks, and can enter the sewage system, increasing the volume of wastewater to be treated.
• Stormwater can cause combined sewer overflows, where untreated sewage and stormwater are released into the environment, posing environmental and public health risks.
• Effective management of stormwater is critical to preventing these overflows and ensuring the efficient operation of sewage treatment systems.
