Epilimnetic Dissolved Oxygen Content and Surface Water Pump Performance
Surface water pumps have been operated and monitored at TVA's Douglas Dam since 1987. The purpose of these pumps is to improve the dissolved oxygen (DO) content of the hydropower...

Scenario for Improving the Seismic Resistance of Pipelines in the Central United States
A number of pipelines transporting crude oil and natural gas to the Midwest and Northeast pass within and adjacent to the New Madrid seismic zone in the central United States. A major...
Earthquake Loss Estimation of the Portland, Oregon Water and Sewage Systems?Evaluation of Concentrated Facilities
This paper summarizes a report that provides an inventory of concentrated water and sewage facilities in two selected drainage basins in the City of Portland. Concentrated facilities include...
Seismic Vulnerability of Memphis Water System Components
The vulnerability of selected components of the Memphis Water System is evaluated herein for a 7.5 moment magnitude earthquake within the southern portion of the New Madrid Seismic Zone....
Seismic Vulnerability Analysis and Upgrade of Seattle Metro Wastewater Facilities
The Municipality of Metropolitan Seattle, Metro, provides wholesale wastewater transport and treatment for 30 cities and sewer districts. A Seismic Vulnerability Assessment Worksheet for...
Putting It Back
Before construction of the largest inclined turbines in the U.S., the Santa Ana River would carry storm flows out to sea, lost to the residents of water-poor Orange County. The area's...
Pumping Oil, Treating Soil
Oil was discovered on hilltop land in Signal Hill, Calif., in 1921, setting off one of the most wild land rushes the state has ever seen. Some 70 years and 20,000 oil wells later, the...
Column Separation in Pumped Pipelines
Pressure transients are common occurrences in water supply systems. Pipeline standards and design/testing techniques will normally provide sufficient protection for transmission and distribution...
The Use of Submersible ROVs for the Inspection and Repair of Water Conveyance Tunnels
At Virginia Power's Bath County Pumped Storage Station, robotic technology was pioneered through the development of a purpose-built Remotely Operated Vehicle (ROV) to gain...
A Methodology for Optimal Control of Pump Stations
Pumping water to utility customers is an expensive service which consumes large amounts of energy. Most approaches to date require simplifications and assumptions for the specific system...
Review of the Design, Construction, and Operation of the Lake Carolyn Flood Control Pump Station
A review of the design, construction, and initial operation of the Lake Carolyn Flood Control Pump Station in Irving, Texas is presented. Staged water resource development design concepts...
Development of an Optimization Model for Groundwater Withdrawal
An optimization model has been developed to simulate optimal values of withdrawal from a given aquifer system. The linear programming technique has been used to formulate the objective...

Temporary Pump Station Keeps Water Flowing
Management of Groundwater Overdraft in the Phoenix, Arizona, Area
By law, the overdrafting of groundwater in the Phoenix, Arizona, area must cease by the year 2025. Safe yield can be achieved by means of conservation, water supply augmentation, and condemnation...
Upgrading of the Orange Cove Irrigation District Water Distribution System
The Orange Cove Irrigation District covers about 28,000 Acres in the Central Valley of California. It is supplied from the Friant-Kern Canal. A semi-closed low pressure pipeline system...
Measurement of Irrigation Water Use: Results of Two Case Studies in Illinois
Three methods of measuring and estimating irrigation pumpage were used during two research studies attempting to assess ground-water use. These three methods: (1) farmer estimates; (2)...
Efficiency Testing of Water Wells
In the operation of a water well, the difference between the water level in the well before pumping starts and after it has been pumping for a period of time is termed 'drawdown.'...
Rehabilitation of Water Wells
The main causes of declining well yield are biological growths, mechanical clogging and chemical encrustation. Because the treatment of the causes of encrustation and clogging is expensive...
