Performance Investigation of Different Large Diameter Water Pipe - PowerPoint PPT Presentation

Performance Investigation of Different Large Diameter Water Pipe Materials Prepared by: Ameya Paradkar, Chandan Venkatesh Pradip Deshmukh, Rahul Manda Tushar Joshi Graduate Students Center for Underground Infrastructure Research and Education (CUIRE) Director: Dr. Mohammad Najafi, P.E., F. ASCE The University of Texas at Arlington Department of Civil Engineering

Disclaimer All pipe materials have advantages and limitations, and can deteriorate over time. Many project specific factors, operations and maintenance procedures of a specific utility, and site and soil conditions around the pipe affect pipe performance. Not all of these factors were considered in the literature used this presentation, or considered in the limited utility survey responses received. Therefore, this presentation cannot be used as basis for selection or rejection of any specific pipe material, and/or to make any design decisions on a project, which is responsibility of design professionals.

Introduction and Background • Water distribution and transmission networks form essential components of water supply systems • Study done by the Center for Underground Infrastructure Research and Education (CUIRE) • Focus is on large diameters (24 in. and larger) for water applications Department of Civil Engineering Department of Civil Engineering

Pipe Materials • High-density Polyethylene (HDPE) Pipe • Polyvinyl Chloride (PVC) Pipe • Cast Iron Pipe (CIP) • Bar-wrapped Pipe • Ductile Iron Pipe (DIP) • Steel Pipe • Prestressed Concrete Cylinder Pipe (PCCP) • Other ( Reinforced Concrete, Asbestos Cement) Department of Civil Engineering Department of Civil Engineering

Objectives • Find details of pipe material inventory in different diameter ranges (24-in. to 36-in., 42-in. to 48-in., and 54- in., and larger) • Identify considerations for not using pipe material • Calculate performance of individual pipe material Department of Civil Engineering Department of Civil Engineering

Methodology • Survey Questionnaire • More than 300 surveys sent to U.S. water utilities • Data received from water utilities is used to analyze performance of pipe materials Department of Civil Engineering Department of Civil Engineering
