SECTION 2 Withdrawals, Discharges and Interbasin Transfers
The Towns’ service areas include Cary, Apex, Morrisville, RDU Airport and RTP South (the Wake County portion of
Research Triangle Park). Because the Towns’ water system service areas straddle the ridge lines between
interbasin transfer (IBT) basins, water is transferred via wastewater discharge, potable water consumptive use, or
reclaimed water consumptive use. The combined IBT amount from the communities served is calculated on a
daily basis.

2 WITHDRAWALS, DISCHARGES AND INTERBASIN TRANSFERS

2.1 IBT Certificate Limits
The Towns’ IBT certificate limits transfers to 31 million gallons per day (mgd) from the Haw River basin to the
Neuse River basin, and to 2 mgd from the Haw River basin to the Cape Fear River basin, calculated as a daily
average of a calendar month.
During calendar year 2017, the Towns were in compliance with the monthly IBT certificate limits. The peak month
transfer from the Haw River basin to the Neuse River basin was 16.1 mgd (52% of certificate limit) which occurred
during July 2017. The peak month transfer from the Haw River basin to the Cape Fear River basin was 0.13 mgd
(7% of certificate limit) which occurred during July 2017.
Daily IBT estimates for the Towns are found in Appendix B. Monthly average daily IBT estimates are found in
section 2.3.
2.2 Summary of Water Withdrawals, Discharges and IBT
The Towns of Cary and Apex are co-owners of the Cary/Apex Water Treatment Facility which has its raw water
intake in Jordan Lake. Cary/Apex, Morrisville and Wake County (for the portion of RTP within that county) each
hold allocations of Jordan Lake water supply storage. Daily tracking of raw water withdrawals from Jordan Lake
for the allocation holders for the period January 1, 2017 through December 31, 2017 is found in Appendix A.
The average daily withdrawal for the Towns was 22.9 mgd during 2017 (Table 2-1). Raw water withdrawals for
Cary (including Morrisville and RTP South) and Apex by calendar year beginning with 2015 are summarized in
Table 2-1. The withdrawals in Table 2-1 do not include withdrawals for intake access. The City of Durham
accessed its Jordan Lake water allocation through the Cary/Apex Water Treatment Facility for 104 days during
calendar year 2017. The City of Raleigh accessed its Jordan Lake water allocation through the Cary/Apex Water
Treatment Facility for 3 days during calendar year 2017.

Morrisville and RTP South. Does not include water use by Durham.
The Town of Cary owns and operates the North Cary and South Cary Water Reclamation Facilities (NCWRF and
SCWRF) which discharge to Crabtree Creek and Middle Creek, respectively. The Town of Apex owns and operates
the Apex Water Reclamation Facility (AWRF) which discharges to Middle Creek. The Towns co-own the Western
Wake Regional Water Reclamation Facility (WWRWRF) which discharges to the Cape Fear River. Process water
from the CAWTF is discharged to a tributary of Jordan Lake. The Town of Cary also has the ability to discharge
wastewater to the Durham County Triangle Wastewater Treatment Plant (Durham Co.) which discharges to a
tributary of Jordan Lake. The Town utilized this ability in 2017, as discussed in section 4.2.

SECTION 3 Consumptive Use by Basin
The average daily consumptive use was 17.2% for the period January 1, 2017 through December 31, 2017.
Consumptive use has ranged between 10% and 23.5% since 2000. Historical consumptive use for each calendar
year beginning with 2015 is shown in Table 3-1.

2016 18.7 2.5 13.3%
2017 19.5 3.4 17.2%

Cary and Apex track historical use by assigning a subbasin to each customer. The distribution of consumptive uses
between the Haw, Cape Fear, and Neuse River subbasins for 2017 was estimated based on historical water use in
each basin as determined by billing records for Cary and Apex.
During 2017, based on 2016 billing records, it was assumed that 29.7% of water use occurred in the Haw subbasin,
1.6% of water use occurred in the Cape Fear subbasin, and 68.7% of water use occurred in the Neuse River
subbasin. During 2018, based on 2017 billing records, it will be assumed that 32.6% of their water use will occur in
the Haw subbasin, 1.4% of their water use will occur in the Cape Fear subbasin, and 66.0% of water use will occur
in the Neuse River subbasin.
Table 3-2 shows the combined water use for Cary (including Morrisville and RTP South) and Apex, and the
percentage water use in the Haw, Cape Fear, and Neuse River subbasins. The table also shows the Haw and Cape
Fear use percentages that will be used for 2017 calculations.

SECTION 4 Discharge Report
The following is addressed in this section as required by Condition 9 of the 2015 IBT certificate and as defined by
the Compliance and Monitoring Plan revised in March 2018:
• Required Discharge
• Actual Discharge
• Compliance Evaluation
Data supporting the computation of Neuse Basin Demand, Required Discharge and Actual Discharge are outlined
in the following sections. If mitigation measures are required, they would be included in this section as well.
4.1 Neuse Basin Demand and Required Discharge
Neuse Basin Demand is the three-year running annual average daily amount of all finished water supplied from
sources within the Haw River (2-1) and Cape Fear River (2-3) Basins, for the three preceding calendar years.
Neuse Basin Demand is the sum of both billed and unbilled use by the Towns in the Neuse River Basin (10-1).
Billed potable water use is quantified from the Town of Apex and Town of Cary water meter and billing databases.
Unbilled amounts of finished water are quantified as a percentage of billed water use. The percentage of non-
revenue water is calculated on a system-wide basis for the Towns on a yearly basis using procedures detailed in
AWWA’s M36 Water Audits and Loss Control Programs publication.
Table 4-1 is a summary of the Neuse Basin demand and required discharge calculations. The total Neuse Basin
demand values for 2015 and 2016 were stipulated in the IBT certificate, modified by the EMC on March 8, 2018.
Appendix C is a summary of the monthly billed water use for Cary and Apex. Appendix D is the output of Town of
Cary’s AWWA M36 Water audit for fiscal year 2017. The non-revenue water percentage in Appendix D is
assumed representative of both Cary and Apex systems. The Neuse Basin treated water purchases summarized in
Table 4-1 are identified on a daily basis in Appendix B.

4.2 Actual Discharge
Actual Discharge is the three-year running annual average daily amount (in mgd) for the three preceding calendar
years of treated wastewater that the Towns of Cary and Apex actually discharge to the Haw River Basin and Cape
Fear River Basin receiving waters, without regard to which Town of Cary or Apex treatment facilities (whether by
ownership or third-party contract) from which the treated wastewater is discharged.
In 2017 the Towns of Cary and Apex discharged highly-treated wastewater effluent to the Cape Fear River Basin
via the Western Wake Regional WRF (WWRWRF) and Durham County Wastewater Treatment Plant (Durham
County). Treated wastewater discharges to Durham County occurred from January 24th to April 14th, 2017 during
a period of emergency sewer line repair in Cary’s wastewater collection system.
Figure 4-1 below shows the Towns’ daily Cape Fear River Basin discharges from WWRWRF and to Durham County
for 2017. Supporting data is found in Appendix E.

SECTION 5 Interbasin Transfer Certificate Conditions
In accordance with the Compliance and Monitoring Plan, the status of the additional eight conditions that the
Towns must meet in order to maintain compliance with the IBT certificate are reported annually. The IBT
certificate conditions and their status during the 2017 calendar year are as follows.
1. Water Conservation Plan – Within 90 days of receipt of the IBT certificate, the Towns are required to submit a
water conservation plan subject to approval by the North Carolina Division of Water Resources (NCDWR) that
specifies the water conservation measures that will be implemented by the Towns to ensure the efficient use
of the transferred water.
STATUS: The Water Conservation Plan was approved by NCDWR on July 14, 2015 and is available on the Town
of Cary website (http://www.townofcary.org/home/showdocument?id=9609) . There were no updates during
calendar year 2017.
2. Drought Management Plan – Within 90 days of receipt of the IBT certificate, the Towns are required to
submit a drought management plan subject to approval by the NCDWR that specifies how the transfer will be
managed to protect the source river basin (Haw River basin) during drought conditions or other emergencies
that occur within the source river basin.
STATUS: The Drought Management Plan was approved by NCDWR on July 14, 2015 and is available on the
Town of Cary website (http://www.townofcary.org/home/showdocument?id=9607). An update was approved
by NCDWR on August 17, 2015 to update the Town of Cary’s approved Water Shortage Response Plan. Those
minor updates were to make the Water Shortage Response Plan consistent with changes in the Town’s
organizational structure, changes in Town Council procedures, and changes in utility billing procedures. There
were no updates during calendar year 2017.
3. Compliance and Monitoring Plan – Within 90 days of receipt of the IBT certificate, the Towns are required to
submit a quarterly compliance and monitoring plan subject to approval by the NCDWR.
STATUS: The Compliance and Monitoring Plan was approved by NCDWR on July 14, 2015. The plan was
revised on March 9, 2018 following the modification of the 2015 IBT certificate to add condition 9. The
current plan is available on the Town of Cary website
(http://www.townofcary.org/home/showdocument?id=19727).
4. EMC Consideration of Alternative Sources – The EMC may reopen and amend the maximum amount of the
IBT authorized if it appears that an alternative source of water is available to the Towns within the receiving
basin (Neuse River basin).
STATUS: No reporting is necessary.
5. EMC Consideration of Future Water Demands – The EMC may reopen and amend the certificate if it is
determined that the Towns’ actual future water needs are significantly less than the projected water needs at
the time the certificate was granted.
STATUS: No reporting is necessary.
6. Resale of Transferred Water – The Towns shall not resell the water that would be transferred pursuant to the
IBT certificate to another public water system.
STATUS: There were no resales of transferred water by the Towns during calendar year 2017.
7. EMC Consideration of Impacts – The EMC may reopen the certificate and amend existing or require new
conditions to ensure detrimental impacts are mitigated if environmental impacts are found to be substantially
different from those on which the EMC’s Findings of Fact were based.
STATUS: No reporting is necessary.
5 INTERBASIN TRANSFER CERTIFICATE CONDITIONS
5-2

8. Intake Access – The Towns shall be required to provide access at their existing intake site to other Jordan Lake
water allocation holders that need access to utilize their allocations to the extent that this additional use is
determined to be feasible by the NCDWR.
STATUS: The Town of Cary has continued to provide retail water service to RTP South and the Town of
Morrisville. Chatham County has continued to access its allocation through the Cary/Apex raw water intake.
The City of Durham accessed its Jordan Lake water allocation through the Cary/Apex Water Treatment Facility
for 104 days during calendar year 2017. The City of Raleigh accessed its Jordan Lake water allocation through
the Cary/Apex Water Treatment Facility for 3 days during calendar year 2017.
9. Required Discharge – The Towns shall discharge to the Cape Fear River Basin and Haw River Basin receiving
waters a calendar year average daily treated wastewater discharge (“Required Discharge”) calculated as:
Required Discharge = Neuse Basin Demand – 9.756 million gallons per day (mgd)
Neuse Basin Demand is defined as the 3-year running annual average daily amount for the 3 preceding
calendar years of all finished water supplied from sources within the Haw River and Cape Fear River Basins,
including both billed and unbilled amounts, expressed in mgd, used by the Towns of Cary and Apex in the
Neuse River Basin. Unbilled amounts of finished water use are to be quantified following the procedures of
AWWA’s Manual of Practice M36, Water Audits and Loss Control Programs.
“Actual Discharge” is the three-year running annual average daily amount (in mgd) for the three preceding
calendar years of treated wastewater that the Towns of Cary and Apex actually discharge to the Haw River
Basin and Cape Fear River Basin receiving waters, without regard to which Town of Cary or Apex treatment
facilities (whether by ownership or third-party contract) from which the treated wastewater is discharged.
STATUS: The Towns of Cary and Apex “actual discharge” was greater than the “required discharge” for the
reporting year 2017.
