Gravity allowed the sewage to flow eastwards, but in places such as Chelsea, Deptford and Abbey Mills, pumping stations were built to raise the water and provide sufficient flow. Sewers north of the Thames feed into the Northern Outfall Sewer, which fed into a major treatment works at Beckton.
As the population of Sheffield increased, Sheffield Corporation bought 23 acres (9.3 ha) of land at Blackburn Meadows, on which to build a sewage treatment works. In August 1884, William Bissett and Son won the contract for its construction, which was overseen by Thomas West, who acted as Clerk of Works. 100 feet (30 m) of standard gauge railway track connected the limeshed to a junction with ...

Blue Plains Advanced Wastewater Treatment Plant in Washington, D.C., is the largest advanced wastewater treatment plant in the world.

That pollution led the U.S. EPA to mandate major upgrades to the city's wastewater system. Requirements included building interceptor tunnels to retain the combined sewage and stormwater for ...
Milking parlour wastes are often treated in admixture with human sewage in a local sewage treatment plant. This ensures that disinfectants and cleaning agents are sufficiently diluted and amenable to treatment. Running milking wastewaters into a farm slurry lagoon is a possible option although this tends to consume lagoon capacity very quickly.
He and his colleagues, including William Haywood, designed an extensive underground sewerage system that diverted waste to the Thames Estuary, downstream of the main centre of population. Six main interceptor sewers, totalling almost 160 km (100 miles) in length, were constructed, some incorporating stretches of London's "lost" rivers.
But wastewater surveillance — the testing of sewage for signs of pathogens such as SARS-CoV-2, poliovirus and mpox virus — has yet to be employed in the tracking of H5N1 bird flu virus.
The U.S. bird-flu outbreak in dairy cattle is much larger than official figures suggest due to farmers' reluctance to test their animals and risk the economic consequences of a positive result ...
