Soil corrosivity was an active problem of water pipeline damaged by corrosion that affects the performance of pipe manufacturers. In Addis ababa, groundwater pipelines were facing breakage and like due to corrosion damage of the pipes. The population of nearly four million were facing a shortage of clean and continuous water supply. Maintenace and replacing old pipes with new ones increased additional cost and delay of water supply for the city. For this investigation of corrosion, causes were conducted which soil property is the one factor. Investigation of soil corrosivity for a given specif

Soil research focuses mainly on soils on land, but the process of soil formation also takes place in shallow waters. Subaqueous soils form below the water surface, mainly on the bottom of shallow, stagnant waters such as bogs, swamps, lakes, and shoals in the sea. Three subaquatic soil profiles were investigated in the Strunjan Bay to study them in detail. The sites for the soil investigation were selected after observing the movement of seawater and thus its possible influence on subaquatic soils. All the soils studied are permanently and year-round under water. Therefore, all soil samples we

The Arkansas Department of Transportation (ARDOT) uses different types of metal culverts and cross-drains. Service lives of these culverts are largely influenced by the corrosion of the metals used in these culverts. Corrosion of metallic parts in any soil-water environment is governed by geochemical and electrochemical properties of the soils and waters. Many transportation agencies including ARDOT primarily focus on investigating the physical and mechanical properties of soils rather than their chemical aspects.

The problem of ageing water pipes manifesting leaks and breaks is common to municipalities throughout Canada, North America, and the world. Among them, the City of Toronto has been confronted with water main infrastructure problems, currently encountering a break rate of roughly two occurrences per week over a network of 5347 km. The appropriate corrective action, which aims to restore pipe integrity and prevent future breaks and leaks, should be decided based on a general knowledge of the state of deterioration of the water main network, a thorough understanding of the governing failure modes

External corrosion is a major factor contributing to the deterioration of cast iron water mains; it weakens the pipe wall, which increases the risk of failure. External corrosion is a function of the interaction between the pipeline and the soil that surrounds it. The aggressiveness of soil towards cast iron is affected by soil properties such as resistivity, pH, and the presence of sulphate reducing bacteria.

Aging water distribution system pipes and valves are at stake due to progressive deterioration. Deterioration of the pipes and valves might be as a result of static, operational and dynamic (time-dependent) factors. The impact of these factors are manifested in the form of declined water quality, diminished hydraulic capacity, increased leakage rate and frequent pipe breaks. Reported literature shows that there are a limited number of comprehensive models which integrate characteristics of these factors. As a result, municipalities have been facing a challenge in predicting pipe failure and pr

Abstract Mercury is a global pollutant that accumulates easily in forest soils, even in remote areas. Mercury accumulated in soils can be subsequently released into surface waters causing an increased eco-toxicological and human health risk. The most toxic form of mercury to humans and wildlife is methyl mercury (MeHg), which can be formed in the environment via methylation processes. In freshwaters, MeHg is readily accumulated in fish, which are the main source of human exposure to MeHg.

Abstract Asbestos cement (AC) piping has been used for potable water, irrigation, drainage and sewer systems for approximately 100 years. The most significant problem affecting the structural integrity of asbestos cement pipes results from the leaching of the cement mortar binder out of the pipe wall. This leaching can occur from the internal surface, depending on the chemical make-up of the water or sewage, or from the external surface, depending on the aggressiveness of the groundwater and soil conditions.

Abstract Asbestos reinforced concrete (ARC) pipes were commonly used for drinking water distribution networks in North American, primarily from middle1940s to early 1980s. In the City of Regina, Canada approximately 68% of all water mains are ARC pipes, to a total length of 535 km. In this preliminary research it was found that bacteriological activities within the internal surface coating (patina) as well as within the concrete could induce bio-deterioration, which eventually leads to pipe failures. Identification of the bacterial consortia was performed using the S43048 protocols for the chr

Abstract Extensive research was conducted on prestressed ASTM A648 Class II steel wire to identify the fracture morphology. Hydrogen embrittlement results when this prestressed steel wire, embedded in concrete cylinder pipe, is cathodically overprotected. From this study, a correlation was established between the environmental variables (pH, cathodic potential) and the type of failure. These experiments demonstrated that hydrogen embrittlement occurred in both environments (pH 2 and pH 12) and affected the fracture behavior of the wires. The wires subjected to cathodic potentials above –1.2 VS

Abstract Flexible pipes are frequently used both as flowlines and risers in the oil and gas industry. A flexible pipe has a complex structure consisting of layers of polymer and metallic materials. The armor wire layers – shielded with polymer materials from seawater on the outside and well fluid on the inside – are the load and pressure bearing parts. Due to diffusion from the well fluid and/or damage of the outer polymer layer, the annulus can be water-filled, and armor wire can corrode. In this work, the susceptibility to hydrogen embrittlement (HE) with the presence of atomic hydrogen due

Abstract The results of an investigation of the corrosion behavior of various T-bolt alloys, used in buried water pipes, are summarized. Three types of soils ranging from mildly to very corrosive were used in testing the T-bolts. Corrosion measurements on Cor-Ten®, a wrought steel alloy, and several cast iron T-bolts are compared based on weight loss and galvanic currents. The ranking of the various T-bolts according to their corrosion resistance was not the same for all three soils. Cor-Ten® T-bolts performed relatively well in some cases.

Abstract Aluminized steel Type 2 (AST2), ASTM A929, has a ~50 um thick coating with outer and inner layers of commercially pure Al and Al-Fe intermetallic respectively. AST2 culvert and drainage pipes are required to have long service life (e.g. 75 yr) in natural soil and water environments; premature pipe failures incur heavy repair and replacement costs. Performance has been adequate in many service conditions, but unexpected early corrosion of AST2 pipes has been recently observed in some Florida inland locations.

Concentrated flow erosion in rills, pipes, ephermal gullies, and gullies is a major contributor of downstream sedimentation. When rill or gullies form in a landscape, a 3- to 5-fold increase in soil loss commonly occurs. The balance between the erosive power of the flow and the erosion resistance of the bed material determines the rate of concentrated flow erosion. The resistance of the bed material to detachment depends primarily on the magnitude of the interparticle forces or cohesion holding the particles and aggregates together. The effect of soil properties on bed material resistance and

Using treated wastewater (TWW) for crop irrigation represents an important opportunity for ensuring adequate food production in light of growing freshwater scarcity worldwide. However, the environmentally sustainable approach of using TWW for irrigation can lead to contamination of produce with fecal pathogens that may remain in treated water. The overall goal of this research was to evaluate the correlation between the presence of fecal indicator bacteria (FIB) and that of a suite of human pathogens in TWW, the irrigated soil, and crops.

The objective of this one-year project was to show whether a significant correlation can be established between the decreasing infiltration rate of the soil, during simulated rainstorm, and a following increase in the reflectance of the crusting soil. The project was supposed to be conducted under laboratory conditions, using at least three types of soils from each country. The general goal of this work was to develop a method for measuring the soil infiltration rate in-situ, solely from the reflectance readings, using a spectrometer.
