“…Yet another crucial internal attribute is the result of external stresses, such as those caused by the surrounding soil, tree roots, vehicles, and impacts by third parties [16], [28], [37], [38]. Interactions with the soil are the main source of external stress; the soil's contraction or expansion caused by temperature variations induces significant stress and causes pipes to deform or break [16], [28].…”

The drinking water mains, mostly buried underground and stay there for decades, require proper maintenance to prevent failures. Among different kinds of material, polyvinyl chloride (PVC) has been widely used due to positive features such as high durability, corrosion resistance, low price, and easy installation. To the best of our knowledge, this is the first paper that reviews the inspection methods toward continuously monitoring the structural health of PVC drinking water mains. To understand which properties need inspecting, we first investigated the attributes that influence PVC pipe and joint failures. Then, we reviewed the methods that have already been applied or can inspect these influencing attributes. We categorized the prospects into five groups: sound wave, fiber optic sensing, hydraulic monitoring, multiple discrete sensors, and other inline methods. Finally, we discussed the possibility and challenges in implementing these methods into a continuous monitoring system of PVC water mains for early failure warning. The result, which includes active sound wave, fiber optic sensing, hydraulic vibration, multiple discrete sensors methods, can help future researchers select the appropriate methods to develop the continuous monitoring system for the PVC water mains.Index Terms-drinking water mains, PVC pipe, pipeline inspection, continuous monitoring, early failure warning, leak, pipe crack. I. INTRODUCTIONG RADUALLY, polyvinyl chloride (PVC) has become the dominant material in the Dutch drinking water mains due to its many advantages such as high durability, resistance to many chemicals, low price, and great flexibility [1]. Although more reliable than other pipes [2], PVC mains also become old

“…They also have additional advantages over rigid materials, such as; no brittle pipe failures due to overloading, low pipe weight, lower risk of leakage at the connection points, excellent chemical resistance, long lifetime, an environmentally friendly solution of the installed pipe systems, possibility to bend the plastic pipe to be installed in curves, relatively high pipe length, and easy jointing. [5][6][7][8][9][10] A finite element model (FEM) of a polyethylene (PE) pipe loaded by internal pressure, residual stresses and soil loads was developed by Poduska et al 11 According to their study, the lifetime of PE pipes exceeds 100 years. Polyvinyl chloride (PVC), high density polyethylene (HDPE), and glass fiber reinforced plastic (GFRP) were widely employed in sewage applications.…”

Advances in technology have provided fresh generations of stiff polypropylene block copolymers for gravity sewerage applications. The aim of this study is to further enhance the stiffness of these materials through the incorporation of inorganic fillers. In this study, three talc filled PP and one glass fiber filled PP composites were characterized in order to be used as a middle layer in a threelayer sewage pipe. The obtained results showed an increase of approximately more than 100% and 250% in tensile and flexural moduli by the use of 30%-50 wt% talc-filled PP and 30 wt.% glass fiber-filled PP, respectively. This high increase in the rigidity of the material would allow manufacturing pipes with improving ring stiffness. Composites filled with 30 wt% talc or glass fiber showed good filler-matrix interaction and good filler distribution and dispersion. However, reduced filler-matrix interaction was observed in the case of the composite filled with 50 wt% talc. In addition, the use of Differential Scanning Calorimetry analysis revealed that the addition of fillers enhanced the crystallization temperature of the polypropylene matrix. Furthermore, Thermogravimetric Analysis showed that the high modulus PP grade retained its thermal stability in the various composites.
