The EA guidance on groundwater infiltration creates an evidence base that must be timely, accurate and effectively deployed.Reliable data is the fuel that enables utilities to demonstrate the benefits of groundwater reduction initiatives across catchments, including improved treatment performance, increased sewer capacity and spill reduction. ...
Environmental protection: Level sensors continuously monitor and track the water level in rivers, lakes, oceans, or sewer systems, collecting data over time and providing alarms to protect against flooding or overflows. ...
Unexpected Find: When Jonathan King found the unfamiliar piece of equipment in a back supply closet, he did not know what to make of it. Called the “SL-RAT”, his first inclination was to sell the hardware. However, after receiving an offer for over $15,000, he decided to investigate further. It turns out, the device was part of a old condition-based maintenance program. This ...
Odour, corrosion and safety risks in sewer network caused by changing weather and climate. The changing climate and weather patterns on sewer management add further complexity for utility operators. ...
Addressing the odour and corrosion challenges faced sewer networks caused by low flows Sewer networks include many miles of sewer pipes and topographical elements, such as rising mains, gravity mains, pumping stations and access points. ...
About 2/3 to 3/4 of this water is typically discharged as wastewater to a municipal sewer system. Based on statistical data, there was approx. 6.3 trillion gallons of beer sold in 2019. ...

When we talk about the water crisis, it’s easy to imagine that these problems are only happening a long way off and only in places that see prolonged periods of drought and very little annual precipitation. This is perhaps especially true for those who call Great Britain home, an island famed for its wet weather and damp climate. The water crisis surely couldn’t rear its ugly head on ...
By combining both liquid and gas smart sensor technology, and as part of a Combined Sewer Overflow (CSO) monitoring solution, SeptiNet improves the control of assets and processes, enabling access to data for both online and offline analysis and modelling. Designed specifically for applications in both wastewater treatment and sewer networks, ...

When the Neuroflux service was adopted in Lahti in January of 2021, the main objective was to examine infiltration and inflow water in the sewer and to locate potentially vulnerable areas. The users quickly found that the service became a natural part of their daily routine: using machine learning to keep up with real-time data turned out to be an intuitive way ...
Digitizing the process of field data collection and infrastructure data management utilizing the GIS Cloud platform, Liburnian waters achieved a multilevel collaboration with local governments, increased their data accuracy, and reduced job timeframe by eliminating paper forms. ...
The aim of this research is to analyse the relationship of rainfall as well as inflow infiltration with sewage flow patterns through data collected from fieldwork. Three sewer pipelines were selected at the residential areas of Taman Lepar Hilir Saujana, Bandar Putra and Kota Sas for data collection. Sewage flow data were ...
As urban sewer infrastructures age, it becomes increasingly important to make effective decisions to maintain the structural condition of the sewers at an acceptable level. To support the decision-making process, the utility manager can apply sewer deterioration models. However, the quality of the decision support from such models is ...
The extraction and reuse of greywater might affect the water and sewer pipe networks by changing flow characteristics. Therefore, the research question is how much greywater can be reused without affecting the existing water and sewer pipe networks? ...
This case study considered two main sanitary sewer collection systems in Bogotá, Colombia. The results showed important differences in COD fractions between the sewer collection systems and the reference data. ...
The present paper describes a novel statistical procedure for defining the prioritization scheme for preventive maintenance strategies based on a small sample of failure data collected by the Sewer Office of the Municipality of Naples (IT). Novelty issues involve, among others, considering sewer parameters as continuous statistical variables and ...
The aim of this paper is to develop a methodology for the prioritization of sewer rehabilitation projects for Algiers (Algeria) sewer networks to support the National Sanitation Office in its challenge to make decisions on prioritization of sewer rehabilitation projects. ...
Reliable prediction of water pollution is essential in festival cities for sewer and wastewater management in order to ensure public health and a clean environment. This article aims to model the biological oxygen demand (BOD5), and total suspended solids (TSS) parameters in wastewater in the sewer networks of Karbala city center during festival and rainy days ...
This paper presents the results of a calibrated 1D/2D coupled model simulating surface and sewer flows in Barcelona. The model covers 44 km2 of the city land involving 241 km of sewers. ...
This paper describes a study of urban flooding in downtown Kunming, China, simulating a major flood event that occurred in July 2008 using an improved two-dimensional (2D) hydraulic model enhanced with courtyard-level sewer data (CLSD). Although municipal authorities are not responsible for ‘private’ courtyard sewers, available ...
