With the infrastructure aging and having to be extended beyond its useful life, the need for municipalities and governmental agencies to do more with less funding is even greater! As such, over the last several years, the use of HDPE for sliplining has increased in its use. Most recently, the use of HDPE for sliplining applications has become a viable alternative for large diameter and pressure pipe rehabilitation.
This presentation will discuss Miami-Dade’s ongoing experience in dealing with their aging infrastructure by using HDPE to slipline both large diameter lines and pressure pipes. The presentation will discuss the HDPE sliplining lessons learned in Miami-Dade and will also discuss some experiences in other regions of the USA. The experience discussed will include case studies involving 72-inch, 42-inch and 36-inch sliplining in both water and wastewater applications. The lessons learned will be highlighted.
A common element in each of the applications in Miami-Dade and in the other installations across the USA that will be discussed is that “Experience Matters”. The experience applies to all aspects of the installation – engineering, material and contractor’s installation.
HDPE is now used in specialized applications across the United States. Examples of this include horizontal directional drilling (HDD) and sliplining existing water and wastewater pipes. Miami-Dade Water and Sewer Department (WADS) has utilized HDPE in these applications. Following is a discussion on one such recent use of large diameter HDPE pipe.
