Trends in offstream water use in Indiana, 1960-90

Water-use data for Indiana from 1960 to 1990 were analyzed to determine general trends of offstream water use. Since 1960, total withdrawals have increased, although there have been periods of increases and decreases. The largest amount of water use (14,300 Mgal/d) occurred in 1980, which was almost 2.5 times more than in 1960. There has been a general increase in withdrawals by public water suppliers, with a trend toward an increasing percentage of population relying on public supplies as their source of water for domestic use. There was an increase in water use by industries during the 1960's, a leveling off during the 1970's, and a general decrease in the 1980's. Industries and powerplants rely heavily on surface water, in Indiana, more water is used for energy production than all other water-use categories combined. Reliability of the data improved significantly in 1985 when facilities capable of withdrawing 100,000 gal/d were required to report their monthly withdrawals annually to the Indiana Department of Natural Resources (IDNR). IDNR maintains these data and makes these data available to the U.S. Geological Survey and other interested parties. In addition, IDNR publishes these data by county for the entire State annually.

Quality-assurance plan for the U.S. Geological Survey Indiana District Water-Use Program

The Indiana District Water-Use Program is an ongoing project with the primary goal of making Indiana water-use data available to Federal, State, and local water managers. The water-use data are obtained from a wide variety of sources. Some data are based on values reported by water users, and other data are based on a variety of estimation techniques. Statements of responsibility, documen- tation and data-storage requirements, sources of data, and methods of achieving project goals are included in this quality-assurance plan. (USGS)

Feasibility of using portable, noninvasive pipe flowmeters and time totalizers for determining water use

The feasibilityty of using noninvasive flowmeters for determining water use was investigated by attempting, and at some sites repeating, instantaneous pipe-flow measurements at 45 water-withdrawal sites by use of four portable noninvasive pipe flowmeters. The flowmeters measure flow in pipes; this flow is related to water use. Because actual water use can differ from the total flow in the pipe, water use is not, in itself, measured by the flowmeters. The transit-time flowmeter successfully measured flow on 81 of 88 measurement attempts. The time-of-flight flowmeter successfully measured flow on 85 of 93 measurement attempts. One reflective-doppler flowmeter successfully measured flow on 71 of 75 measurement attempts. Another type of reflective-doppler flowmeter, which required air bubbles or paniculate matter in the flow, successfully measured flow on 19 of 92 measurement attempts. Flows at most water-withdrawal sites selected for this study did not include paniculate matter. At 10 site visits where inline flowmeter measurements were available for comparison and where three of the four selected portable flowmeters were successful, the transit-time flowmeter measurements had a mean log-percent difference from the inline measurements of 2.8 and a standard deviation of 3.7. The time-of-flight flowmeter measurements had a mean log-percent difference of 7.5 and a standard deviation of 7.6. The reflective-doppler flowmeter measurements had a mean log-percent difference of -14 and a standard deviation of 18. The feasibility of using time totalizers for determining water use was investigated by observing seven vibration time totalizers (VTT's) mounted at five sites. None of the units exhibited adverse effects from the heat, precipitation, or humidity associated with Indiana summers. One VTT was mounted at a public water-supply site where inductive time-totalizer measurements were available for comparison. The VTT agreed within 8 hours of the inductive time totalizer after 2,340 hours of pump operation. There were no mechanical prpblems with the VTT units used in this study.
