Abstract Sanitary sewage network is relatively rarely considered as the cause of urban floods. Its hydraulic overload can result not only in flooding, but also sanitary contamination subcatchments. Stormwater main reason for this overload. In contrast to stormwater or combined sewer system, these waters infiltrate into an uncontrolled way, through ventilation holes covers structural faults and ...

The safe access to water and sanitary sewer are human rights, there is a lack of indexes which evidence if rural areas have levels these services others compose basic sanitation in Brazil. goal this work was elaborate safety index at household level, apply it three typologies communities the state Goiás: settlements, quilombola riparian communities. For such, research developed five steps: 1) C...

BACKGROUND In most developing countries, open defecation is the 'way of life'. This practice is considered as the most serious health and environmental hazard. Prime Minister of India launched the "Swachh Bharat Mission" to accelerate the efforts for achieving universal sanitation coverage and to put focus on sanitation. OBJECTIVE To find the knowledge, attitude and practices of sanitary latr...

Hydrogen sulfide (H2S) related to wastewater in sewer systems is known for causing significant problems of corrosion and odor nuisance. Sewer severely affected by H2S typically rely on online gas sensors monitoring control. However, these only provide information about the emission potential at point being monitored, which sometimes inadequate design control measures. In this study, a compariso...

Extreme rainfall events cause an increase in the flow into aging sewer networks, which can lead to Sanitary Sewer Overflows (SSOs). This literature review presents a complete assessment of application Water Sensitive Urban Design (WSUD) approaches as mitigation strategies for reducing rainfall-induced SSOs. The highlights various WSUD techniques identified past studies overflows. In these studi...

If all parameters influencing sewer performance were known (or deterministic) then the decision making process associated to the planning of sewer replacement should be relatively straightforward. However, when trying to forecast service life, uncertainties arise considering the deterioration process, the variability of sewer pipe properties, environmental conditions or the used information res...

Combined Sewer Overflows (CSO) of 671 Functional Urban Areas (FUAs) throughout the European Union + UK (EU28), representing almost half EU28 population. CSO loads can be quantified at local scale through measurements, or with calibrated hydrological models. However, they are difficult to quantify a large (e.g. regional national), due lack data, and models used cannot applied in absence knowledg...

Abstract The biggest problem with sanitary technology in high-rise buildings is the design of foul water stacks which high negative pressure and overpressure values must not occur. When exceeds maximum values, from trap ejected, sucked out, or left bubbling trap. Measurements by other researchers have shown that when traps lose their function, addition to spreading unpleasant odors, there also ...

the 6th national population and housing census was carried out from october 28 to november 17, 2006 in which three different questionnaires were used. question number 55 of the 3rd questionnaire asked about housing units sewage disposal. this paper studies and analyzes the answers to the mentioned question in regional and national levels. assessment of housing units sewage disposal conditions s...
