Corrosion Assessment

Various methods of corrosion assessment on drinking water distribution pipelines have been reviewed in this paper. Five methods of corrosion assessment consisting of sampling method, scanning method, ultrasonic testing method, electromagnetic inspection method and corrosion index assessments described provide valuable information regarding their implementation mechanisms. Since each method has its advantages and limitations, the application of methods on the pipeline must consider the environmental conditions of the pipeline to be inspected, as well as the equipment and resources available.

Corrosion can lead to degradation of water quality and affect the mechanical characteristics of drinking water piping systems. Alternative solutions consist of replacing traditional inorganic materials by plastic materials. A review of the organic materials used in drinking water distribution systems is presented in relation to their specific application. Future aspects of the European Regulation for Drinking Water Construction Products and the next European Approval Scheme (EAS) are developed.

Corrosion Assessment

Corrosion assessment is an important aspect in asset and facilities management. Generally the purpose of corrosion assessment is to assure the activities of the management will be effective and efficient. Lack of corrosion assessment can be decrease the function and reduce the life cycle of assets and facilities caused by corrosion. Corrosion is an electrochemical or chemical reaction between a material, usually a metal, and its environment that produces a deterioration of the material and its properties. Even though most of the dangers from corrosion occurs in major industrial plant, corrosion also has a great impact on the drinking water industry. In drinking water distribution pipelines, corrosion damage cause the leakages of distribution pipelines and around 30% of water supplied to consumers is lost. Most of the leakages of drinking water distribution pipelines are initiated by lack of corrosion assessment and poor maintenance because the pipes are usually located underground. To overcome this problem, an effective corrosion assessment method is imperative to get the accurate information about the condition of the pipelines. This will ensure better decisions for repair or replacement of the pipelines before they fail. This review paper describes the corrosion assessment model and the major parameters considered for drinking water distribution pipelines.

Concerns arise from the possible occurrence of pathogens in drinking water pipe biofilms and storage tank sediments. In these studies, biofilm samples from pipes and sediments from storage tanks of the Lisbon drinking water distribution system were analyzed. Protein determinations and heterotrophic counts on pipe biofilm samples were used to assess the Lisbon network sessile colonization intensity and distribution. Indicator and pathogenic microorganisms were analyzed in pipe biofilm samples, as well as in storage tanks biofilm and sediments, by using cultural methods and PCR, to assess risks. Results have shown that the Lisbon network sessile colonization is relatively weak in intensity. In addition, no meaningful hazards were apparent for both the network biofilm and the storage tanks biofilm and sediments.

Background: Multidrug-resistant bacteria can lead to treatment failure, resulting in infectious diseases being transferred through nonpotable water. Aminoglycosides are an important class of antibiotics that are abused in Nigeria. Few studies have investigated aminoglycoside-modifying genes (AMGs) that are likely responsible for resistance in Nigeria bacteria isolates. Therefore, we aimed to characterize AMGs from isolates in drinking water distribution systems (DWDS) in southwestern Nigeria. Methods: Multidrug-resistant bacteria (n = 181) that had been previously characterized by 16S rDNA sequencing and that were positive for resistance to at least 1 aminoglycoside antibiotic were selected from 6 treated and untreated water distribution systems. Strains were PCR genotyped for 3 AMGs: aph(3)c, ant(3)b and aph(6)-1dd. Results: Of 181 MDR bacteria tested, 69 (38.12%) were positive for at least 1 of the AMGs. The most common was ant(3)c (27.6%), followed by aph(3")c (18.23%). Both aph(3)c and ant(3")b were found in 7.73% of tested isolates, ant(3)b was most commonly found in Alcaligenes spp (50%). Furthermore, aph(3")c was most commonly detected in Proteus spp (50%). Other genera positive for AMGs included Acinetobacter, Aeromonas, Bordetella, Brevundimonas, Chromobacterium, Klebsiella, Leucobacter, Morganella, Pantoae, Proteus, Providencia, Psychrobacter, and Serratia. Conclusions: High occurrence of ant(3)c and aph(3)c among these bacteria call for urgent attention among public health workers because these genes can be easily disseminated to consumers if present on mobile genetic elements like plasmids, integrons, and transposons.Funding: NoneDisclosures: None
