Wastewater Treatment for Better Environment
Wastewaters from households, industries, and combined sewers are collected and transport to the treatment plant with the effluent commonly disposed of by dilution in rivers, lakes or estuaries....
Numerical Modeling of Salinity Transport in a Shallow Well-Mixed Tidal Reach
This paper is concerned primarily with the development of numerical salinity transport model using 8-point implicit finite difference scheme for predicting the salinity variation in a...
New York Bight Three-Dimensional Water Quality Model
The numerical modeling technology developed for Chesapeake Bay was applied to the Middle Atlantic Bight extending 550 km form Cape May, NJ, northeasterly to Nantucket Island, MA, and extending...
A Flexible Curtain Structure for Control of Vertical Reservoir Mixing Generated by Plunging Inflows
To maintain salmon habitat in the Sacramento River, efforts are being made to pass cold water inflows through Whiskeytown Reservoir, California, with minimal warming. In Whiskeytown, summer...
Self-Cleaning Wet Wells: Definition and Design
Design guidelines for self-cleaning wet wells with variable speed pumps are given and the progress of research at Montana State University and ENSR Consulting and Engineering concerning...
Installing a Raw Water Line by Microtunneling
Construction began in 1991 on a new water treatment plan for the Towns of Cary and Apex, with B. Everett Jordan Lake as a water source. Installation of two 1,400 mm raw water lines approximately...
The Ivie Pipeline Delivering Water to West Texas
The Ivie Pipeline is a $76,000,000 - 156-mile long water pipeline being constructed in West Texas. This paper describes highlights of the planning, design, and construction phase....
Evaluation of a Proprietary Tape Coating Alternative for the 157 Mile Ivie Pipeline
A two part evaluation of alternative protective coating systems for the 157 mile Ivie pipeline was made. In Part I, an evaluation was made on the suitability of a proprietary tape coating...
An Evaluation of Fiberglass Pipe Made by Three Different Manufacturing Processes for use in Water Transmission Projects
Fiberglass pipe is made primarily using continuous filament wound process, discontinuous helical filament wound process, and centrifugal cast process. Some 40 countries around the world...
Management of Sewer System Rehabilitation for the Overflow Abatement Program in Nashville, Tennessee
To comply with a state order to abate overflows of wastewater from the sanitary sewerage system, the Nashville, Tennessee, Metropolitan Department of Water and Sewerage Services has undertaken...
Analysis and Design of Direct Burial Sections of San Diego County Water Authority's Pipeline 4 Extension
