Decentralized Wastewater Management
With the discovery earlier this century that city squalor caused disease, we protected ourselves by piping raw wastes away. Later, when the discharge had transformed rivers into foul,...
Soil-Pipe Interaction During Frost Heaving Around a Buried Chilled Pipeline
The freezing of soil water around a buried chilled pipeline leads to soil heaving, which is affected by the presence of the pipe. This process may eventually cause pipeline failure. The...
Numerical Analysis of Frost Shields
The term 'frost sheilding' has been used to describe the practice of using flat stock rigid insulation materials burial above a water or sewer pipe to reduce...
Wang's Equation for Ice Forces From a Pressure Ridge
Yung-shih (Tony) Wang has presented an equation for the breaking loads from a multiyear pressure ridge on a conical structure. The three distances that define the position of the plastic...
Procedure for Seismic Evaluation and Design of Small Bore Piping
Simplified methods for the seismic design for small bore piping in nuclear power plants have been used for many years. Various pipe designers have developed unique methods to treat the...
Recirculation Piping Replacement Project at Dresden Unit 3
This paper discusses the Recirculation Piping Replacement Project performed at Dresden Unit 3 during 1985 and 1986. It describes several of the technical and administrative problems associated...
Simplified Second-Order Inelastic Analysis for Steel Frame Design
Several current approaches are outlined that account for the spreading of plasticity in a second-order inelastic analysis of frames. The approaches are based on modifications to the simple...
Emplacement Drift Temperature Reduction by Cooling Enhancement and Ventilation
The application of cooling enhancement in a short vertical container emplacement layout is analyzed. Two 25 m-long heat pipes upward oriented at 45 degrees are installed at each emplacement...
Structural Shape Optimization: An Implementable Algorithm
A computational algorithm for optimal shape design of linearly elastic structures is presented. For this problem continuum as well as discrete formulations have been developed and analyzed...
Boston's Sewage Outfall
The centerpiece of the Boston Harbor cleanup plan will be the sewage plant on Deer Island, which will treat water from 43 municipalities in the Boston metro area�500 mgd to start. In order...
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...
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...
The Danby Pipe Renovation System
This paper describes a pipe renovation system and its structural characteristics which is cost effective and technically suitable in all sizes of pipe from 8 inches (200 mm) to the largest...
Rebuilding Buried Pipelines Without Digging
Advances and refinements in trenchless reconstruction technologies now permit system rebuilding of gravity and low pressure pipelines without excavation. Through the use of cured-in-place...
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...
Block-based Solvers for Engineering Applications
This paper compares the performance of standard linear system solvers, LINPACK, widely used in engineering applications, and PARALIN (a block-based package for linear systems) on the Alliant...
