TL;DR: The use of polyvinyl chloride (PVC) has become one of the dominant construction materials for sewer systems over the past decades, as a result of its reputed merits.
Abstract: Polyvinyl chloride (PVC) has become one of the dominant construction materials for sewer systems over the past decades, as a result of its reputed merits. However, since PVC sewer pipes have operat...

TL;DR: IR frame analysis and 2D temperature mapping demonstrate that: i) the detection limit is very low (ratio between lateral and main discharges: 0.025) and ii) the quantification of the lateral discharge is impossible.

TL;DR: In this article, the authors show that polyvinyl chloride (PVC) sewer pipes have operated for decades in a hostile environment, raising concern among sewer managers over the longevity of their drainage systems.

TL;DR: In this article , the potential of vibro-acoustics to detect physical ageing of plastic pipes was explored, where the axisymmetric water-borne wave was used to quantify the storage modulus of a plastic pipe and an uncertainty analysis revealed the parameters that must be more accurately known.
TL;DR: In this paper , an alternative method, called fingerprinting, was developed and tested in this study, which utilizes wastewater treatment plant (WWTP) influent samples and derives the proportion of stormwater in a sample by comparing the wet weather vs dry weather concentrations of substances-tracers which are present only in wastewater.

TL;DR: A new method to develop real-time FSS models driven by water consumption data from associated water distribution systems (WDSs) as they often have a proportionally larger number of sensors is proposed.

TL;DR: In this article, a state-of-the-art review of trenchless rehabilitation methods for concrete pipelines, including spray-in-place, grouting, sliplining, modified slipline, cure-inplace pipe, close-fit, and fiber-reinforced polymer lining, is presented.
Abstract: Concrete-based pipelines or linings are widely used for water and sewer systems. However, concrete pipes suffer from the problems of aging and deterioration due to complex loading (internal and external), severe service environments, and the brittle nature of concrete. This paper provides a state-of-the-art review of trenchless rehabilitation methods for concrete pipelines, including spray-in-place, grouting, sliplining, modified sliplining, cure-in-place pipe, close-fit, and fiber-reinforced polymer lining. In addition, an emerging structural retrofit method with Engineered Cementitious Composites (ECC) was introduced. The rehabilitation methods were classified into non-structural, semi-structural, structural, as well as the retrofit of structure and function. The technical features, advantages, drawbacks, and application conditions of each method were summarized to provide the basis for method selection. ECC can be applied as a coating by manual spraying and centrifugal spraying methods. The tailored characteristic of self-stressing enhances the integrity of the ECC liner and host pipe. The intrinsic advantages of ultra-high tensile ductility, anti-corrosion, jointless technique, tiny crack widths, self-healing behavior, as well as low cost make ECC a sustainable and resilient material for pipe rehabilitation and retrofit with increased load capacity, enhanced durability, and leakage-proof performance.
