The management of urban sewer systems requires data about variability and discharge of typical waste water sources in urban catchments. Especially the infiltration of groundwater and the inflow of surface water (I/I) are important for decisions about rehabilitation and operation of sewer networks. In this paper a new methodology is presented which supports the identification and quantification ...

This paper describes the first radar based forecast of flow and/or water level in sewer systems in Denmark. The rainfall is successfully forecasted with a lead time of 1-2 hours, and flow/levels are forecasted an additional 1⁄2-11⁄2 hours using models describing the behaviour of the sewer system. Both radar data and flow/water level model are continuously updated using online rain gauges and on...

The paper sketches KURT, an autonomous robot platform prototype that is able to navigate inside a network of sewage pipes. KURT is a six-wheeled device; it has modular, layered hardware and control architectures. Its sensor connguration consists mostly of stationary and one exible ultrasound sensors and of two inclinometers. In experiments run in a test sewerage system consisting of concrete pi...

Sewer system is fundamental urban infrastructure for the public sanitation. Construction of sewer system is needed to invest a huge amount of capitals and labours as well as generates various and wastes and atmospheric emissions, and hence sewer pipes should be appropriately managed in the environemental aspect which is analysis of greenhousegases(GHGs) emissions. In this study, we investigated...

TRC undertook a study in 2011 focusing on the township of Crows Nest as its flagship for assessing the existing infrastructure and the development of a future sewer system. The study was designed to identify whether a conventional gravity system would be a more cost-effective option than a pressure sewer system. Consideration of various conditions such as population densities, topographic const...

For roughly forty years, from 1870 to 1910, Americans recognized and feared gases emanating from sewers, believing that they were responsible for causing an array of diseases. Fears of sewer gas arose from deeper anxieties toward contact with decomposing organic matter and the vapors emitted from such refuse. These anxieties were exacerbated by the construction of sewers across the country duri...

This paper presents an overview of causes of sewer deterioration together with a discussion of control methods that can prevent or arrest this deterioration. In particular, the paper covers inlineand combined sewer overflow(CSO) storage-tank-flushing systems for removal of sediments and minimizing hydrogen sulfide production resulting in the reduction of associated pollution and sewerline corro...

The usage of tethered, remotely controlled robot platforms in sewer pipes has become widely accepted. Research and development in engineering have moved the original application field of merely visual inspection to manipulative tasks such as the actual repair of pipe sections, installation of cable, e.g. for communication. Despite all engineering advances in the mechanical design of the platfor...
