An Investigation of Field Performance of Reinforced Plastic Mortar Pipes
Every year many new pipe materials appear on the market for various applications. One of the important factors the design engineer and the user should consider while evaluating new products...
Successful Rehabilitation of Sewers at Hawaii Kai
Two common problems in sanitary sewer deterioration are hydrogen sulfide attack to concrete pipe and structures and infiltration leakage into the system. Within the 100 miles (160 km)...
Los Angeles' Small Main Programs
Large quantities of small diameter mains within Los Angeles' water distribution network has necessitated the development of new main improvement programs. The introduction...
The Use of Restrained Joint Ductile Iron Pipe
This paper addresses some of the problems we at U. S. Pipe have observed from restrained joint installations during the past several years and the solutions devised. The restrained joints...
Thrust Restraint of Buried Ductile Iron Pipe
It is the intent of this paper to present current state of the art thrust restraint design, present a basis for calculating required lengths of restraint, and to offer some practical suggestions...
Pipeline Rehabilitation with Polyolefin Pipe
This paper provides an introductory discussion on the rehabilitation of a deteriorated pipe structure by insertion renewal with continuous lengths of polyolefin pipe. This sliplining or...
Use of In-Place Lateral Reconstruction for Correction of Infiltration/Inflow
Extensive sewer collection system rehabilitation programs have done much and will continue to correct infiltration/inflow problems. However, re-evaluation of some of the earlier projects...
Getting to the Root of Sewer Problems
The ability to quantify and qualify work schedule in a clear, logical and precise manner can make the difference between an effective preventive maintenance program and one of 'trying'...
Internal Sealing of Large Diameter Pipelines
Underground piping has traditionally been repaired by making excavations at the joints and completing the repairs externally. However, with increasing labor costs, underground utility...
The Applicability of U.K. Sewerage Rehabilitation Techniques to the U.S.
The total length of public sewers in the UK is 160, 000 miles and in recent years there has been increasing concern over their conditions. Research spearheaded by the Water Research Centre...
Rehabilitation of the Seekonk River Interceptor Sewer, Providence, Rhode Island
The Seekonk River Interceptor, located in Providence, Rhode Island and owned by the Narragansett Bay Commission, is a combined sewer system originally built in the late 1800s. Portions...
Design of Ductile Iron Pipe Systems
To ensure a reliable, low maintenance infrastructure capable of withstanding the test of time, proper initial design is essential. The basis of the design standard for ductile iron pipe...
Pipe Geometry and Pipeline Bridge Wind Oscillation
Static and modal analyses of two pipeline suspension bridges owned by American Natural Resources - the Patterson Loop Aerial Crossing (PLAC) with a span of 850 feet (259 meters) and the...
An Investigation of the Supports of a Water Main
Two 48 inch (1. 22 m) diameter cast iron pipes constructed 50 to 70 years ago form a major part of the potable water transmission system of Atlantic City. For the most part of their length,...
Sliplining with Ductile Iron Pipe
The utilization of Ductile Iron Pipe (DIP) as an alternative to be considered for sliplining rehabilitation of sewer pipelines is evaluated. A recent experience in sliplining a failing...
Rehabilitation of Terminal Ballast Water Piping
In order to maintain the integrity of the ballast water piping system at the Marine Terminal of the trans-Alaska pipeline, a composite lining system was installed in the 42-inch (1,067...
Pipeline Infrastructure Rehabilitation
A significant amount of technological development has occurred during the past ten (10) years regarding the actual rehabilitation methods, or reconstruction procedures on the decaying...
Trenchless Techniques for Pipeline Installation, Renovation and Replacement
New construction methods have been developed primarily in Europe and Japan for underground pipeline work. The new methods, known as trenchless techniques, are primarily used when existing...
Monitoring the Effects of the Pipe Insertion Machine Technique
The results of an experimental study of the pipe insertion machine are presented in this paper. Strains induced in an adjacent pipeline, soil displacement, pipe deflection and vibrations...
Water Main Cleaning and Lining?A Utility Perspective
