Plastic Pipes and Their Use in Rainwater Drainage Systems

1755-1315/988/5/052032

This paper studies the conditions for the use of plastic pipes in rainwater drainage systems. In this research, the author undertakes a literature review and finds out that the share of plastic pipes in the construction of gravity sewage network has significantly increased over the past 20 years. Plastic pipes low roughness ensures higher flow rates of wastewater. The peculiarity of rainwater drainage calculating methodology leads to the fact that an increase in the speed of wastewater movement leads to the formation of larger wastewater discharge in the design section of the pipeline with the same rainfall intensity. It is established that at present the cost of rainwater drainage systems construction from polypropylene pipes is 80-100% higher than from reinforced concrete (excluding the construction of pumping stations and wastewater treatment facilities).
