Deterioration and leakage of drinking water in distribution systems have been a major issue in the water industry for years, which are associated with corrosion. This paper discovers that occluded water in the scales of the pipes has an acidic environment and high concentration of iron, manganese, chloride, sulfate and nitrate, which aggravates many ...

Assessing water quality of drinking water distribution system in the South Taiwan
Environmental Monitoring and Assessment, 2007This investigation conducted a full-scale survey the drinking water distribution system in Kaohsiung city, Taiwan. The aim was to investigate whether the distribution system was capable of maintaining high water quality from the water treatment facilities through to the end user.

Modeling temperature in the drinking water distribution system
Journal AWWA, 2013According to the Dutch Drinking Water Directive of 2001, the maximum temperature of drinking water should be 25°C. Occasionally, samples at the tap do exceed this limit, and with global warming, this limit may be exceeded more often. This article describes a model that predicts the temperature of the water in the drinking water distribution system ...

Potential for biofilm development in drinking water distribution systems
Journal of Applied Microbiology, 1998Regrowth of micro-organisms in drinking water distribution systems is caused by the utilisation of biodegradable compounds which are either present in treated water or originate from materials in contact with drinking water. In the Netherlands most drinking water is distributed without disinfectant residual and regrowth is limited by achieving ...

Heterotrophic bacteria in drinking water distribution system: a review
Environmental Monitoring and Assessment, 2011The microbiological quality of drinking water in municipal water distribution systems (WDS) depends on several factors. Free residual chlorine and/or chloramines are typically used to minimize bacterial recontamination and/or regrowth in WDS. Despite such preventive measures, regrowth of heterotrophic (HPC) and opportunistic bacteria in bulk water and ...

Biofilms in Drinking Water Distribution Systems
1992The degradation of water quality due to bacterial growth in the drinking water distribution systems is a major concern for consumers as well as for drinking water producers. Microorganisms (bacteria, yeasts, fungi, protozoa) may be found both in the water phase and on the surface of the pipe walls in the form of a biofilm.These thin layers (apart from ...

[Bacterial regrowth in drinking water. II. Drinking water distribution systems].
Zentralblatt fur Bakteriologie, Mikrobiologie und Hygiene. Serie B, Umwelthygiene, Krankenhaushygiene, Arbeitshygiene, praventive Medizin, 1988Five chromium steel dead-end water pipes were installed over a distance of 12 km along the Zurich city drinking water distribution system. Cell counts were determined in two series of four samplings in fresh water and stagnating water using three different methods.

Effect of flow fluctuation on water pollution in drinking water distribution systems
Environmental ResearchThe detachment of biofilm caused by changes in hydraulic conditions is an essential reason for the pollution of water in the drinking water distribution system (DWDS). In this research, the effect of flow fluctuation on bulk water quality was studied.
