Analysis and evaluation of the measurement system based on KAMA orifices for measuring the flow of sewage in the light of the water law requirements

Acta Scientiarum Polonorum. Formatio Circumiectus, 2019
The new water law introduces the need to control the value of sewage discharge, if its average daily amount exceeds 0.01 m3·s-1. That is why there is a need to build a monitoring system for discharges from sewage treatment plants and large rainwater ...

Evaluation of a Real-Time Control System for Combined Sewer Networks [PDF]

, 2007
In this study, we evaluated the amount of reduction of the combined sewer overflow (CSO) load using real-time control (RTC) for a combined sewer system region where a storage basin had been constructed.

Sewage leakage challenges urban wastewater management as evidenced by the Yangtze River basin of China

npj Clean Water
Sewage leakage, including uncollected, collected but exfiltrated, and collected but discharged with stormwater in combined sewer overflows, becomes a key challenge to clean water around the world.

Urban blocks enable data-reduced, hydraulically sound planning for combined sewer overflow mitigation

Water Research X
Combined sewer overflows (CSOs) remain a major source of urban water pollution, exacerbated by increasing rainfall extremes and expanding impervious surfaces.

Infiltration drives a heavy–tailed distribution of combined sewer overflow spill durations

Environmental Research Communications
Combined sewer overflows (CSOs) discharge untreated wastewater into natural water bodies during periods of excess sewer flow, posing environmental risks. Using ∼4 million CSO spill events recorded by Event Duration Monitors across England (2020–2024), we

Modelling the adoption of combined sewer overflow surveillance in Switzerland

Water Science & Technology
ABSTRACT During wet weather, combined sewer overflows (CSOs) spill untreated wastewater to hydraulically protect wastewater treatment plants. Interestingly, in Switzerland, the impact of these discharges on surface water quality remains unclear due to limited monitoring of CSO spills.

Micropollutant Emissions from Combined Sewer Overflows

, 2023
Anthropogene Stoffeinträge beeinträchtigen den chemischen und ökologischen Zustand von Gewässern. Eine beständig zunehmende Anzahl und Vielfalt von Mikroschadstoffen – die in niedrigen Konzentrationen im Bereich von Nano- bis Mikrogramm pro Liter auftreten – gibt Grund zur Besorgnis erheblicher ökotoxikologischer Risiken und stellt den Gewässerschutz ...

Prioritizing Low‐Income Groups and the Environment in Communities with Poor Water Quality [PDF]

, 2016
When a community has poor water quality, the U.S. Environmental Protection Agency (EPA) requires it to comply with federal standards in accordance with the Clean Water Act (CWA).

The role of open data in regulating combined sewer overflows

Water Science & Technology
ABSTRACT The aim of this work is to investigate how open data can play a beneficial role in the regulation of combined sewer overflows (CSOs). The investigation consists of a review and critical discussion of historic CSO design, alongside more recent developments of regulations and emerging experiences of monitoring CSOs
