Current World Health Organization and Centers for Disease Control and Prevention guidance for the disposal of liquid waste from patients undergoing treatment for Ebola virus disease at hospitals in the U.S. is to manage patient excreta as ordinary wastewater without pretreatment. The potential for Ebolavirus transmission via liquid waste discharged into the wastewater environment is currently...

1. Urban drainage systems fal into two categories: “separated” systems where stormwater and sewage is reticulated in separate reticulation systems; and “combined” systems where the same pipes are used for both. The report deals exclusively with the urban litter problems associated with the stormwater conduits and streams in a country where the stormwater and sewage are always (theoretically at ...

Distributed temperature sensing (DTS) with fiber-optic cables is a powerful tool to detect illicit connections in storm sewer systems. High-frequency temperature measurements along the in-sewer cable create a detailed representation of temperature anomalies due to illicit discharges. The detection limits of the monitoring equipment itself are well-known, but there is little information availabl...

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 ...

Combined sewer overflow (CSO) pollution is the main factor that plagues water environment in area with combined system most cities of China. This paper analyzed CSO pollution, and reviewed measures to solve latest research progress. The problems traditional river interception projects were analyzed, optimization improvement ideas proposed. Finally, a scheme source reduction-process control-end ...

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...

The combined sewer overflows (CSO) pollution has caused many serious environmental problems, which aroused a worldwide concern. Traditional interception-storage measures, exhibit the disadvantages of larger storage tank volume and low concentration, cannot efficiently control CSO pollution. To solve this problem, water quality-based double-gate strategy based on real-time (PBRTC) rule was propo...

Operational and structural interventions in the field of stormwater management are usually planned based on long-term simulations using rainfall-runoff models. The simulation results often highly uncertain due to imperfections model structure inevitable uncertainties input data. trend towards monitoring combined sewer overflows (CSO) structures produces more data which can be used replace parts...
