Effects of Natural Gas Storage on Gas Price Forecasts
This paper explores the effects of natural gas storage on short-term gas price forecasts. At the Southern California Edison Company (Edison), the gas price forecast incorporates a multitude...
A G.I.S. for Cross Country Pipelines
Faced with an increased workload, greater information demands and a limited staff, the Civil Engineering Section of Columbia Gas Transmission is trying a different approach to the selection...
Infrared Thermography Based Pipeline Leak Detection
Computerized Infrared Thermographic pipeline inspection is now a refined and reliable process having been thoroughly proven to be an accurate, cost effective, and efficient technology...
Automatic Control of a Sewage Interceptor
This paper presents a control system for the automatic operation of a sewage intercepter with control gates to reduce sewage discharge to the receiving waters. One of the issues of the...
Design Program for Gravity Sanitary Sewers
The Gravity Sewer Design Program Version 2.1 M (GSDP2M) performs the hydraulic design for a conventional gravity sanitary sewer network. GSDP2M is written in standard Fortran 77 for batch...
Application of GIS in Monitoring and Trouble Shooting of Water Distribution Systems
In this study, the suitability of Geographical Information System (GIS) to monitor water distribution systems is investigated. Although GIS applications are widespread, the use of GIS...
Diagnostic Options for Pipeline Rehabilitation
The various diagnostic options utilized for solving pipeline problems/failures continue to increase at a very rapid pace. Field reconnaisance and/or man-entry of pipelines is becoming...
Rehabilitation of Urban Pipelines
The City of Los Angeles is embarking on a replacement and rehabilitation program for the distressed portions of its sanitary sewer system which will cost in the hundreds of millions of...
Reliability Consideration in Capital Improvement Programs
This paper shows an application of network reliability modeling in water supply capital improvement programs. The proposed approach consists of combining geometrical and structural properties...
Water Distribution Infrastructure Analysis
Water distribution systems in many older cities of the United States need rehabilitation. Because the rehabilitation costs of the nation's water systems will involve billions...
Los Angeles' Pipeline Rehabilitation Program
One-third of the City of Los Angeles' 7,000 mile water distribution system had been installed without internal protection. The Water System is aiming for a 900,000 foot per...
Heuristic Optimization of Water Distribution Systems
A design heuristic for the optimization of water distribution systems is presented. Algorithm TREESEARCH finds a near optimal core tree layout. Algorithm REDUNDANCY adds redundant links...
Computer Modeling as a Tool for Selecting Appropriate Air Valves for Pipeline Surge Protection
Waterhammer in water or wastewater pipelines is caused by events such as a pump power failure and can have potentially damaging effects on the pipeline or pipeline hardware. In particular,...
Network Modeling in a Water System with Ferrous Deposits
This paper presents the experiences and results of a network modeling study. A model for the University of Idaho water supply system was developed and verified to the extent possible with...
A Comprehensive Algorithm for Network Calibration
An explicit calibration algorithm is proposed which provides the direct and rapid adjustment of the pipe roughness coefficients and junction node demands that exactly meet a specified...
A Water Information System for Decision Support in Design, Operation and Management of Distribution Systems
The design, operations and management of water supply and distribution systems require considerable amounts of data and data processing and analysis. What is not available to the water...
Rehabilitation of Water Distribution Systems Planning and Implementation
The paper describes the approach taken to develop infrastructure rehabilitation procedures for Water Distribution Systems. Early research attempted to develop a mains condition oriented...
