“…Variation in total MPs content (polypropylene, polyethylene, polystyrene, polyethylene terephthalate, and polyvinyl chloride) along a pipeline showed a decrease in MPs concentration in water from 1570.8 n•L −1 at water intake to 377.0 n•L −1 at the end of the pipeline network [245].…”

The inner walls of the drinking water distribution system (DWDS) are expected to be clean to ensure a safe quality of drinking water. Complex physical, chemical, and biological processes take place when water comes into contact with the pipe surface. This paper describes the impact of leaching different compounds from the water supply pipes into drinking water and subsequent risks. Among these compounds, there are heavy metals. It is necessary to prevent these metals from getting into the DWDS. Those compounds are susceptible to impacting the quality of the water delivered to the population either by leaching dangerous chemicals into water or by enhancing the development of microorganism growth on the pipe surface. The corrosion process of different pipe materials, scale formation mechanisms, and the impact of bacteria formed in corrosion layers are discussed. Water treatment processes and the pipe materials also affect the water composition. Pipe materials act differently in the flowing and stagnation conditions. Moreover, they age differently (e.g., metal-based pipes are subjected to corrosion while polymer-based pipes have a decreased mechanical resistance) and are susceptible to enhanced bacterial film formation. Water distribution pipes are a dynamic environment, therefore, the models that are used must consider the changes that occur over time. Mathematical modeling of the leaching process is complex and includes the description of corrosion development over time, correlated with a model for the biofilm formation and the disinfectants–corrosion products and disinfectants–biofilm interactions. The models used for these processes range from simple longitudinal dispersion models to Monte Carlo simulations and 3D modeling. This review helps to clarify what are the possible sources of compounds responsible for drinking water quality degradation. Additionally, it gives guidance on the measures that are needed to maintain stable and safe drinking water quality.

“…This matrix consists primarily of polysaccharides, proteins, glycolipids, phospholipids, nucleic acids and enzymes that provide nutrients for bacteria in the early stages of biofilm development (Biedroń et al, 2017). The EPS also allows retention and accumulation of organic and inorganic matter (Liu et al, 2014; Peng et al, 2010; Peng & Korshin, 2011), heavy metals (e.g., As) (Liu et al, 2014), a variety of pathogens (Feazel et al, 2009; Fish et al, 2017; Liu et al, 2017; Vaerewijck et al, 2005) and possibly microplastic particles (Novotna et al, 2019; Pivokonsky et al, 2018; Tao et al, 2023). The process of biofilm development in drinking water distribution systems is multistep, and bacteria use intercellular signaling known as quorum sensing (QS) for its efficient expansion and stable functioning (Lami et al, 2022; Liu, Ling, et al, 2016; Shrout & Nerenberg, 2012).…”

“…At a further stage, treated water is transported to consumers through often very extensive distribution networks (DWDNs), which include both underground pipelines with connections to buildings as well as internal networks in buildings (Ainsworth, 2013; Lam et al, 2020; Liu et al, 2017). The pipes that makeup DWDNs, with lengths often exceeding hundreds, or even thousands, of kilometers, are made of different materials (concrete, cast iron, steel, and plastics) that are joined by welds and valves (AWWA, 2012; Liu et al, 2017; Pratesi et al, 2021; Tao et al, 2023; Vreeburg & Boxall, 2007). Depending on the function performed in the system (main, building supply, etc.…”

In recent years, metal alloys used for drinking water distribution are gradually being replaced by PVC and HDPE pipes. In areas of distribution networks made of plastic, consumer complaints related to a significant deterioration of organoleptic parameters of water are frequently recorded. The decline in water quality is most likely the result of chemical and biological processes occurring on the inner walls of the transmission pipes coexisting with the disappearance of disinfectant residues. Plastic pipes are also characterized by high failure rates associated with aging of polymeric materials under operating conditions. Published reports indicate disturbing phenomena occurring in plastic pipes: oxidative aging of polymers, degradation of antioxidant coatings, release of organic compounds to water as well as surface damage and scaling, generating microplastic particles. PE and PVC networks are also susceptible to biofilm formation, characterized by a high phylogenetic diversity of microorganisms. Studies presented in the literature, indicating the risks resulting from the exploitation of PE and PVC pipes, are mainly based on model tests. There is a lack of works, which would complementarily explain all the phenomena occurring in working water pipes made of plastics. The aim of this review is to present the current state of knowledge regarding the phenomena and processes that can occur in PE and PVC pipes in service and their relevance to the safety and quality of drinking water in distribution networks, as well as to identify areas that require further analysis to enable water producers to deliver an appropriately high‐quality product to consumers.This article is categorized under: Engineering Water > Water, Health, and Sanitation Science of Water > Water Quality Water and Life > Conservation, Management, and Awareness
