Social/Physical Impacts And Water Consumption Characteristics Of South Dakota’S Rural Water Systems, Matt Pajl, Delvin E. Deboer

Water and Environmental Engineering Research Reports

This study investigates the social and physical impacts that rural water systems have on South Dakota’s population and the water consumption characteristics of city, country dwelling, and farm customer classifications. The physical characteristics of South Dakota’s rural water systems along with the 2006 water production and sales information were used to determine and relate the unique distribution characteristics and water consumption demands of the rural water systems. The impact of improved water quality to the customers of the rural water systems was shown in improved livestock production and health, customer softening salt savings, and reduction of total dissolved solids entering …

Effects Of Storage Tank Mixing On Water Quality, Andy Lemke, Delvin E. Deboer

Water and Environmental Engineering Research Reports

Storage tanks are used by water systems to maintain pressure in the distribution system and to meet the varying water demands of the system. The design and operation of the storage tanks affect their mixing characteristics which affect the water quality. Poor mixing can lead to stratification in the tanks, which can lead to low chlorine residual causing microbial growth and nitrification. This thesis presents the results of the study of seven storage tanks used in South Dakota’s rural water systems. The tanks were chosen to represent varying height to diameter ratios, varying types of disinfectant, and to study passive …

The Effects Of Tank Operation And Design Characteristics On Water Quality In Distribution System Storage Tanks, Christopher T. Olson, Delvin Deboer

Water and Environmental Engineering Research Reports

From the Executive Summary

Background:
Regional water systems utilize storage facilities to meet demand variations and pressure requirements of their systems. These storage facilities drain and fill in response to system water demands and water level control settings. Storage tanks are typically placed in strategic locations to maintain a consistent pressure in the distribution system. Storage facilities should be designed and operated such that the water is mixed to prevent stagnant water (old water that remains in the tank for an extended period). Stagnant water can lead to water quality issues, such as low disinfectant residuals, potential for microbial contamination, …

Economic Impact Of South Dakota’S Regional Water Systems, Matthew J. Pajl, Delvin E. Deboer, Gary Taylor, Dwight Adamson

Water and Environmental Engineering Research Reports

Regional water systems are a primary conduit of water supply for much of South Dakota’s rural and small community populations. As of 2006, greater than one-third of South Dakota’s population was served by water supplied from regional water systems, and when Lewis and Clark Rural Water delivers water to Sioux Falls, over one-half of South Dakota’s population will be served by regional water systems. Greater than 75% of incorporated communities with public water supplies are served by regional water systems, either as bulk communities or as individual customers. Many farms and agricultural industries use rural water for domestic use, livestock …
