Predicting wastewater temperatures in sewer pipes using abductive network models
A predictive modelling technique was employed to estimate wastewater temperatures in sewer pipes. The simplicity of abductive predictive models attracts large numbers of users due to their minimal computation time and limited number of measurable input parameters. Data measured from five sewer pipes over a period of 12 months provide 33,900 training entries and 39,000 evaluation entries to ...

An approximate solution for two-dimensional groundwater infiltration in sewer systems
Estimating groundwater infiltration into sewer systems is important for wastewater treatment operators and municipalities. This paper presents an approximate solution for steady-state groundwater infiltration into sewer systems through line defects. The groundwater table was assumed to be horizontal and the aquifer homogeneous and isotropic. Mobius transformation technique and equivalent ...

How having the Right Pipe Bursting Equipment Can Boost Trenchless Repair Service Providers
A Trenchless Repair for sewer pipes has been trending in parts of the country. It allows for pipes to be fixed or replaced without trenches being dug into the yard or landscape. It also allows the problem to be fixed without the mess of digging up existing structures such as; porches, driveways, sidewalks, and much more. It is important for business’s who advertise the Trenchless Repair to ...

An expert system with radial basis function neural network based on decision trees for predicting sediment transport in sewers
In this study, an expert system with a radial basis function neural network (RBF-NN) based on decision trees (DT) is designed to predict sediment transport in sewer pipes at the limit of deposition. First, sensitivity analysis is carried out to investigate the effect of each parameter on predicting the densimetric Froude number (Fr). The results indicate that utilizing the ratio of the median ...

The efficiency of asset management strategies to reduce urban flood risk
In this study, three asset management strategies were compared with respect to their efficiency to reduce flood risk. Data from call centres at two municipalities were used to quantify urban flood risks associated with three causes of urban flooding: gully pot blockage, sewer pipe blockage and sewer overloading. The efficiency of three flood reduction strategies was assessed based on their effect ...

Rapid detection of sewer defects and blockages using acoustic-based instrumentation
Sewer flooding incidents in the UK are being increasingly associated with the presence of blockages. Blockages are difficult to deal with as although there are locations where they are more likely to occur, they do occur intermittently. In order to manage sewer blockage pro-actively sewer managers need to be able to identify the location of blockages promptly. Traditional closed-circuit ...

Assessment of erosion and sedimentation dynamic in a combined sewer network using online turbidity monitoring
Eroded sewer sediments are a significant source of organic matter discharge by combined sewer overflows. Many authors have studied the erosion and sedimentation processes at the scale of a section of sewer pipe and over short time periods. The objective of this study was to assess these processes at the scale of an entire sewer network and over 1 month, to understand whether phenomena ...

An exploratory study of the effects of stormwater pipeline materials on transported stormwater quality
Implications of three sewer pipe materials (concrete, galvanized corrugated steel, and polyvinyl chloride (PVC)) for stormwater quality were explored in laboratory experiments, in which three types of stormwater, SW1–SW3, were circulated in 0.5 m long sewer pipe sections. SW1 and SW2 represented synthetic rainwater, without and with fine street sediment added (CTSS = 150 mg/L), respectively, ...

Are All Sewer Pipes The Same?
This Sewer Camera blog explains the differences between various sewer pipes that plumbers, home inspectors, and homeowners should be aware of. If you are a homeowner, it’s unlikely that you think about the sewer pipes running underneath the ground that are connected to your home. However, they do play a critical role in ensuring that your plumbing systems operate and function correctly. ...

New Project Sample - Case Study
In-house pipe bursting provides a cost-effective solution for I & I reduction Challenge Replace 200 miles of aging sewer pipe at 5 miles/year over 40 years with predictable costs and reliable ROI, to get rid of I/I spikes in one of the wettest climates on America’s West Coast. Solution We help this California sewer authority meet its primary objective of combating I/I ...

Tighter Sewer Joints - The Responsible Choice Case Study
Municipal engineers can ensure sewer piping systems remain leak-free throughout their operating life by specifying solutions that offer tighter sewer joints. Leaking joints in a sewer piping system result in the loss of soil fines in the bedding around the pipe. As water percolates out of a leaky joint, it mechanically erodes the bedding material around the pipe joint. While this loss not only ...

Modelling the viability of heat recovery from combined sewers
Modelling of wastewater temperatures along a sewer pipe using energy balance equations and assuming steady-state conditions was achieved. Modelling error was calculated, by comparing the predicted temperature drop to measured ones in three combined sewers, and was found to have an overall root mean squared error of 0.37 K. Downstream measured wastewater temperature was plotted against modelled ...

A support vector regression-firefly algorithm-based model for limiting velocity prediction in sewer pipes
Sediment transport without deposition is an essential consideration in the optimum design of sewer pipes. In this study, a novel method based on a combination of support vector regression (SVR) and the firefly algorithm (FFA) is proposed to predict the minimum velocity required to avoid sediment settling in pipe channels, which is expressed as the densimetric Froude number (Fr). The ...

Saved Over $1 Million in Unnecessary Expenses
Santa Barbara, CA - The City of Santa Barbara (CSB) serves nearly 100,000 customers. During the seasonal rains, deteriorating and aging sewer pipes permit unwanted I/I to enter the system raising the risk of sanitary sewer overflows. Santa Barbara recognized that a more comprehensive understanding of their systems performance was necessary to more proactively manage and rehabilitate the City’s ...

How Does Sewer Camera Help to Inspect Drain and Sewage Pipes?
A sewer camera is a widely used inspection method that helps diagnose damage in sewer pipes in both residential and commercial applications. This pipe camera can accurately identify the possible problem that could be causing the issue. Early detection helps in repairing the issue at the initial stages. In this way, it helps in saving money incurred on larger sewer pipe repairs in the future. Due ...

Global sensitivity analysis of an in-sewer process model for the study of sulfide-induced corrosion of concrete
The presence of high concentrations of hydrogen sulfide in the sewer system can result in corrosion of the concrete sewer pipes. The formation and fate of hydrogen sulfide in the sewer system is governed by a complex system of biological, chemical and physical processes. Therefore, mechanistic models have been developed to describe the underlying processes. In this work, global sensitivity ...

Will greywater reuse really affect the sewer flow? Experience of a residential complex in Al Ain, UAE
Reuse of recycled wastewater is one of the most feasible unconventional urban water sources in the United Arab Emirates (UAE). 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? A residential ...
