The sewer inspection robot MAKRO is an autonomous multi-segment robot with worm-like shape driven by wheels. It is currently under development in the project MAKRO-PLUS. The robot has to navigate autonomously within sewer systems. Its first tasks will be to take water probes, analyze it onboard, and measure positions of manholes and pipes to detect polluted-loaded sewage and to improve current ...

Previous evidence has identified potential racial disparities in access to community water and sewer service in peri-urban areas adjacent to North Carolina municipalities. We performed the first quantitative, multi-county analysis of these disparities. Using publicly available data, we identified areas bordering municipalities and lacking community water and/or sewer service in 75 North Carolin...

corrosion makes huge economic and ecologic damage all over the world. biologic corrosion of sewer pipes is considered as a serious limitation in economic perspectives. to prevent biologic corrosive damage, lining techniques can be applied by materials and aggregate resistant to attack bacterially in sewer pipes. the role of bacteria is that they convert sulfur compounds into sulfuric acid which...

Sewer odors have been a concern to citizens of the Metropolitan Seoul region, which has installed combined sewer systems (CSSs) in 86% of its area. Although a variety of odorants are released from sewers, volatile sulfur compounds (VSCs) have been recognized as major ones. A number of technologies have been proposed to monitor or control odors from sewers. One of the most popular strategies ado...

The historically African-American Rogers-Eubanks community straddles unincorporated boundaries of two municipalities in Orange County, North Carolina, and predates a regional landfill sited along its border in 1972. Community members from the Rogers-Eubanks Neighborhood Association (RENA), concerned about deterioration of private wells and septic systems and a lack of public drinking water and ...

How do you feel when you hear the words " wastewater, " " sludge, " " sewer, " and " sewage " ? These words may make you feel uncomfortable. However, as Victor Hugo wrote in " Les Misérables, " these words are inevitably related to human society (16): " ... The history of men is reflected in the history of sewers. The Germoniae narrated Rome. The sewer of Paris has been an ancient and formidabl...

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...
