A Statistical Comparison Of A Direct Filtration And A Conventional Water Treatment Facility In The Intermountain Region, Susan K. Burns, V. Dean Adams

Reports

Interest in low-cost direct filtration facilities and their effectiveness in treating the potable water sources of the Intermountain Region is increasing as the need for treated water supplies increase. Direct filtration is a water treatment scheme which does not include sedimentation and in some cases flocculation. Compared to conventional treatment, direct filtration has lowered capital costs, reduced space requirement, and decreased sludge quantities. Moreover, the direct filtration process may offer large reductions in coagulant dosages and costs.

Currently information comparing a direct filtration system to a conventional water treatment system in the Intermountain area is not readily available. The specific …

New Concepts For Preliminary Hydropower Design: The Powermax Slope, Binary Turbine Sizing, And Static Regain, Frank W. Haws, Eugene K. Israelsen

Reports

In Utah during the 1960s, the cost of producing electrical energy was as much, or in some cases more, by hydroelectric generation than by plants using steam from coal fired boilers. The relatively high hydropower cost was generally attributed to maintenance and replacement costs associated with plants that had been build in the 1920s. Utah Power & Light Company during the 1960 period decided not to renew power licenses and to abandon many small hdyroplants. Since 1973, rising coal and related fossil fuel costs have caused steam generation costs to accelerate and have made hydroelectric generation relatively more attractive. However, …

A Groundwater Model Of Cache Valley, Utah, Calvin G. Clyde, Roland W. Jeppson, Win-Kai Liu

Reports

This report describes the development, calibration and use of quantitative, predictive management model for the groundwater in the Utah portion of the Cache Valley in northern Utah. The quasi-three-dimensional finite difference computer model was adapted from the U.S. Geological Survey’s Trescott and Larson model and simulates the groundwater levels and flows in the groundwater basin. The variable spacing grid system is 23 nodes x 38 x 2 and represents the complex natural system by a simpler approximation with one unconfined and one confined aquifer and the appropriate boundary and initial conditions. River nodes, spring nodes, and constant head nodes were …

Direct Filtration Versus Conventional Water Treatment In The Intermountain Region, Susan K. Burns, V. Dean Adams, Steel B. Maloney

Reports

The direct filtration water treatment scheme does not include sedimentation and in some cases flocculation. Compared to conventional treatment, direct filtration has lowered capital costs, reduced space requirements, decreased sludge quantities, and reduced coagulant dosages. One objective of this research was the statistical comparison of the direct filtration, Utah Valley Water Purification Plant (Orem, Utah) and the conventional Little Cottonwood Water Treatment Plant (Salt Lake City, Utah). These treatment plants are the two most compatible treatment plants having the highest correlation of source water in the local area. The Little Cottonwood plant receives approximately 65 percent of its sources water …

Sediment-Phosphorus Relationships In Deer Creek Reservoir, Jay J. Messer, Thomas B. Hardy, Jean M. Ihnat

Reports

Summary and Conclusions: Laboratory analyses of sediment samples recovered from Deer Creek Reservoir showed the sediments to have amoderate potential for serving as a source of phosphorus (P) for the overlying water solumn under anaerobic conditions. This source could account for the occurrence or exacerbation of blue-green algal blooms in the upper end of the reservoir when the sediment surface becomes anaerobic late in the summer. It could also delay the response of the reservoir to programs that decrease external P loading, if the upper end of the reservoir still has large enough algal blooms to render the sediment-water interface …

Summary Report: Updating The Estimation Of Water Surface Elevation Probabilities And Associated Damages For Great Salt Lake, L. Douglas James, David S. Bowles, D. George Chadwick, J. Paul Riley

Reports

Problem Statement: Rising levels of the Great Salt Lake are severely impacting private and public property. in the private sector, the mineral industry, the railroad, and a number of recreation enterprises are suffering major damages. In the publi sector, the State of Utah is esperiencing large losses inflicted on roads and highways, waterfowl and related wildlife areas, and park and recreation facilities. The lake is partitioned by a semipervious railroad causeway into a north and a south arm with the sourth arm having about twice the water surface area and usually being two or three feet higher because it receibes …

Trihalomethane Compounds And Their Precursors In Salt Lake County: Evaluation Of Trihalomethane Source And Production, Kyle R. Cook, V. Dean Adams, Dennis B. George, Vincent A. Lamarra, Richard A. Hanson

Reports

Salt Lake County, Utah, watershed streams, drinking water treatment plants, and distribution systems were monitored for a period of one year or greater to determine the seasonal watershed precursor load, trihalomethane (THM) formation, and correlation between the two in the drinking water supplies. In addition, unit treatment processes were examined at Parleys, Big and Little Cottonwood water treatment plants, in the spring and late summer, to evaluate THM precursor reduction and THM formation. Additional studies were also conducted to appraise the potential contribution of natural sources to watershed THM precursor loading. Total organic carbon was used to estimate THM precursor …

Management Of Groundwater Recharge Areas In The Mouth Of Weber Canyon, Calvin G. Clyde, Christopher J. Duffy, Edward P. Fisk, Daniel H. Hoggan, David E. Hansen

Reports

Proper management of surface and groundwater resources is important for their prolonged and a beneficial use. Within the Weber Delta area there has existed a continual decline in the piezometric surface of the deep confined aquifer over the last 40 years. This decline ranges from approximately 20 feet along the eastern shore of the Great Salt Lake to 50 feet along in the vicinity of Hill Air Force Base. Declines in the piezometric surface are undesirable because of the increased well installation costs, increased pumping costs, decreased aquifer storage, increased risk of salt water intrusion, and the possibility of land …
