Technical Memorandum
PROJECT: CW-DMAG - Engineering Support
DATE: March 3, 2010
SUBJECT: Water Use Summary Report for Calendar Year 2009
1.0 Background and Purpose
This Technical Memorandum (TM) documents the analysis and results for water use in the Catawba -
Wateree River Basin (the Basin) for calendar year 2009. The data collection and analysis have been completed
in coordination with the Catawba - Wateree Drought Management Advisory Group (CW-DMAG). Annual
water use summary reports have been prepared for every year since 2006.
The CW-DMAG, seeking to document water withdrawal reductions for public water suppliers during the
most recent drought, has also been gathering and analyzing data regarding residential water use. This
evaluation compares average residential water use during and after the most recent drought period (2007 -
2009) to historical average residential water use (1999 - 2006) to determine what impact the Low Inflow
Protocol (LIP) and subsequent conservation efforts, have had on residential water use. It should be noted
that use of the tern "historical" in this report, as applied to residential average water use, is based on a limited
time period for reporting entities which immediately precedes the introduction and implementation of the
Basin's LIP. For the first time, this residential water use analysis has been included in this annual water use
summary report.
2.0 Data Gathering and Summary Procedure
CW-DMAG members are required by provisions in the LIP to provide annual water use data by January 31St
for the preceding calendar year. The data includes the total volume of water withdrawn from and/or
returned to surface waters of the Basin. These volumes are translated into annual average flowrates and
compared to the corresponding water use projections developed for the 2006 Catawba-Wateree Water Supply
Study (WSS). The 2009 water use data is also compared to actual water use data collected for the years 2006 -
2008 to help identify possible trends. Table 1 presents the comparison of these data sets.
Water use information was not gathered directly from some entities listed in Table 1. Where possible, 2009
actual flowrates for these water users were collected from the Environmental Protection Agency's (EPA's)
Envirofacts Warehouse electronic database. Those water users that could not be found through the EPA
database were assigned their respective projected 2009 water use flowrates from the WSS. In Table 1, where
2009 projected flowrates were used in lieu of actual flowrates, data is recorded in `red' text and the rows are
not highlighted. Actual water use data that were reported by water users are recorded in `black' text and the
rows are highlighted. Approximately 85% of the Basin-wide water withdrawals and 91% of the Basin-wide
water returns were derived from actual data obtained for 2009.
To evaluate the effectiveness of the LIP and the drought's recent impact on the Basin's residential water use,
thirteen public water suppliers submitted monthly residential water use data for nearly 340,000 customers.
These "reporting entities" represent the vast majority of the overall residential water use in the Basin. All data
for water use prior to 2007 (-1999-2006, varies by reporting entity) was used to create an historical monthly
average water use uninfluenced by the organized and coordinated water use restrictions associated with a
2009 Water Use Summary Report 1 of 3 March 3, 2010
regional LIP. The monthly water use for the 2007 - 2009 period was then compared to these historical
monthly averages.
3.0 2009 Water Use Observations and Conclusions
Table 2 summarizes 2009 actual/estimated data and their corresponding WSS 2009 projections. This
comparison is important because the WSS projections were used for modeling of the Catawba - Wateree
water supply system during the FERC relicensing process to assess the impacts of water use on the Basin's
safe yields over a range of hydrologic conditions. Table 3 summarizes actual/estimated data for the years
2006 - 2009 along with projected water use for future years. An analysis of this data results in the following
observations /conclusions:
¦ Actual water withdrawals and returns are both less than those projected in the WSS for 2009.
However, since both withdrawals and returns were proportionally lower, the departure of actual net
withdrawal (or net outflow) from the WSS projections is minimal - approximately 12%.
• Overall, water withdrawals from the Basin have steadily declined since 2006. While WSS projections
predicted nearly an 8% increase from 2006 - 2009, actual water withdrawals for the basin have
decreased by 19% since 2006. While no individual sub-basin has seen an increase in water
withdrawals during this time period, the vast majority of the reduction has been realized in the
Mountain Island, Wylie, and Fishing Creek sub-basins.
• Overall, water returns to the Basin have also steadily declined since 2006. While the WSS projected
nearly a 6% increase in water returns from 2006 - 2009, actual water returns for the Basin have
decreased by 30% since 2006. While no individual sub-basin has seen an increase in water returns,
the vast majority of the reduction has been realized in the Wylie and Fishing Creek sub-basins.
• Net water withdrawal has experienced essentially no change from 2008 to 2009. Since 2006, actual
net withdrawal has decreased by 7%.
• The departure of actual water use from the WSS projections is likely attributable to several important
factors, including:
Over the past several years, several large industries have reduced or ceased operations.
The current economic recession has significantly slowed growth and development in many
communities within the Basin.
Economic conditions in 2009 have led many industrial water users to reduce consumption.
4 Several water utilities have increased water rates or instituted/modified tiered rates, which
encourage lower water use by customers.
4 Behavioral changes by customers to reduce water use during recent drought conditions (via the
LIP) continue to have a lingering effect.
The water reductions are seen most clearly in the middle portion of the Basin and are due to the large
concentration of population and industry in this area.
In addition to the tables referenced above, Figure 1 presents actual net withdrawals by water use type (e.g.,
public water systems, industrial users, power) from 2006 - 2009. Figure 2 compares actual net withdrawals
from 2006 - 2009 to the net outflows projected in the WSS over the entire study period.
4.0 LIP and Drought Impacts on Water Use for Calendar Years 2007 - 2009.
2009 Water Use Summary Report 2 of 3 March 3, 2010
Table 4 presents the average monthly residential water use for the 2007 - 2009 period from reporting entities.
A comparison of that use to historical average residential water use is shown in Figure 3. The same
comparison is presented in Figure 4, but 2007 - 2009 water use is represented as a percent departure from the
historical average. For example, in January 2007, the residential water use was 5,013 gallons/customer and
the historical average January water use is 5,539 gallons/customer. Therefore, residential water use was
approximately 9.5% lower than the historical average, as indicated in Figure 4. Analysis of this data results in
the following observations/conclusions:
• LIP Stage 2 mandatory water use restrictions, which went into effect in September 2007, had an
immediate and sustained effect on reducing residential water use. In the span of approximately two
months, residential water use dropped from 13% above average use to 18% below average use.
• Subsequent changes in water use restrictions tended to be followed by negligible change in water use,
even when these changes had the effect of easing water restrictions (e.g., March 2008, September
2008, May 2009). While this phenomenon seems counter-intuitive, possible explanations include:
The easing of water restrictions coincided, and were driven by, periods of wet weather. Even if
the revised water restrictions would allow for greater water use (particularly outdoor watering),
the wet weather may have reduced the need for outdoor watering, thereby lowering water use.
4 Changes to water restrictions typically were made through official announcements and
disseminated to the public via print and television media. It is possible that such announcements
had the effect of reemphasizing the importance of water conservation, thus temporarily altering
water use behavior.
• Since the end of the drought, residential water use has remained significantly below historical
averages. Although water use appears to be trending closer to the historical averages, the recovery is
modest. There is not enough data yet to clearly determine when, or if, water use will return to
historical averages. However, possible reasons to explain this trend include:
-* Customer behaviors and motivations were changed regarding outdoor water use.
4 Several water utilities have increased water rates or instituted/modified tiered rates, which
encourage lower water use by customers. These changes, coupled with the current economic
climate, lead to reduced water use.
4 Precipitation since the end of the drought has been higher than normal, which has likely reduced
the amount of outdoor watering.
The water use patterns seen in this residential data are consistent with, and help to explain, the
observation that actual water use for calendar year 2009 is below that which was projected in the
2006 WSS.
The annual reporting requirement for CW-DMAG members and the subsequent data analysis efforts provide
an important evaluation of key assumptions and modeling input parameters that were used to support Duke
Energy's relicensing efforts. To date, only four calendar years have been captured, two of which include a
significant drought that affected the water use behavior within the Basin. It will continue to be important to
gather and analyze this data so that future attempts to manage and model water use within the Basin can be
accomplished with the correct perspective, facts, and assumptions.
