International public infrastructure explainers
Clear explanations of sewer systems, wastewater treatment plants, lift stations, force mains, overflows, biosolids, maintenance, and utility-scale wastewater planning.
Understand sanitary sewers, manholes, lift stations, force mains, inflow, infiltration, blockages, inspection, and cleaning programs.
Learn how treatment plants reduce pollutants, manage effluent, remove nutrients, disinfect, and handle sludge and biosolids.
Explore funding, asset management, climate resilience, emergency planning, industrial pretreatment, odour, and corrosion.
A plain-English overview of wastewater systems, from collection sewers and lift stations to treatment plants, effluent, biosolids, maintenance, and planning.
Topics: wastewater systems, sewers, treatment plants
How sanitary sewers collect wastewater, why slope and pipe condition matter, and how service connections, manholes, trunk sewers, and maintenance fit together.
Topics: sanitary sewers, gravity sewers, manholes
How wastewater treatment plants use physical, biological, chemical, disinfection, and solids-handling processes before treated effluent is released or reused.
Topics: treatment plants, primary treatment, biological treatment
Why wastewater systems use lift stations and force mains, how pumps move sewage through difficult terrain, and why reliability matters.
Topics: lift stations, force mains, pumps
How rainwater and groundwater enter sanitary sewers, why that extra flow can overload pipes and treatment plants, and how utilities reduce it.
Topics: inflow, infiltration, I&I
What combined sewers are, why combined sewer overflows happen, and how communities reduce overflow frequency and impact.
Topics: combined sewers, CSO, overflows
