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 ...

Large Florida Utility Saving Money through Innovation - Case Study
After spending decades and millions of dollars rehabilitating sewer pipes across its service area, a large coastal utility embarked on a pilot pipe condition assessment program for 25,000 linear feet in areas prone to high unwanted infiltration rates. Electro Scan’s Focused Electrode Leak Location technology, or FELL, offers an innovative departure from legacy pipe inspection methods, such ...

Comparing the utility of decision trees and support vector machines when planning inspections of linear sewer infrastructure
Closed-circuit television inspection technology is traditionally used to identify aging sewer pipes requiring rehabilitation. While these inspections provide essential information on the condition of pipes hidden from day-to-day view, they are expensive and often limited to small portions of an entire sewer system. Municipalities may benefit from utilizing predictive analytics to leverage ...

A new vision on the condition of city of Toronto’s sewer networks
Situation And Objectives After the amalgamation of Toronto in 1998, Toronto Water – the department in charge of managing the combined infrastructure systems – was mandated to consolidate all underground facilities data and centralize sewer inspection processes on behalf of the newly merged city. Ten years later, a great deal of work in this regard remained undone. It was a monumental ...

Risk assessment study for water supply network using GIS
In recent years, contamination of water in water distribution systems (WDS) has been recognized as a major cause of waterborne diseases. Owing to old and deteriorated pipes, and the presence of pollution sources in contact with the supply line, water boards often decide to replace the network in the interests of public health. This being a cost-intensive and time-consuming programme, decision ...

Common features of Videology pipe and sewer inspection cameras
Inspection cameras used in pipelines, plumbing systems and storm drains are designed to help professionals inspect and diagnose problems in pipes and sewer systems. A visual inspection is the key to identifying existing or potential problems in these hard-to-reach structures. Usually located under the ground, drains, sewers, manholes and other pipelines are confined spaces that a human eye cannot ...

Evaluating the role of deterioration models for condition assessment of sewers
Ensuring reliable structural condition of sewers is an important criterion for sewer rehabilitation decisions. Deterioration models applied to sewer pipes support the rehabilitation planning by means of prioritising pipes according to their current and predicted structural status. There is a benefit in applying such models if sufficient inspection data for calibration, an appropriate ...

Effect of Enhanced Biochemical Processes in the Sewer Collection System on Influent Wastewater Characteristics and Wastewater Treatment Plant Performance
Short Abstract (less than 100 words) In-Pipe Technology (IPT) employs sewer collection system bioaugmentation treatment to enhance the sewer biochemical processes by improving the microbiology in the collection system, and provides improved microbiology to the wastewater treatment plant (WWTP). In this presentation, the effect of IPT sewer collection system bioaugmentation on sewer biochemical ...
