1 INTRODUCTION 

1‐2 
To meet the annual reporting requirements of the Plan, the following sections of this 2018 Annual Report include: 
 Status of compliance with IBT certificate limits. 
 Summary of historical water withdrawals, reclaimed water usage, wastewater discharges and IBT for the 
January to December calendar years beginning with 2015. 
 Table of calculated daily average of calendar month IBT amounts for the 2018 reporting year. 
 Summary of amount of water used during 2015 to 2018 by customers in the Neuse River, Haw River, and 
Cape Fear River basins for use in determining the distribution of consumptive uses among the basins. 
Based on the amount of water used in each basin for the previous year, the distribution of consumptive 
use by basin in the following calendar year will be determined and documented. 
 Discharge Report, documenting Required Discharge and Actual Discharge. 
 Status of compliance with IBT certificate conditions. 
Appendix A is a table of daily Jordan Lake water supply allocation raw water withdrawals for Cary/Apex, 
Morrisville and Wake County/RTP South for January 1 to December 31 of the 2018 reporting year. 
Appendix B is a table of calculated daily IBT amounts for January 1 to December 31 of the 2018 reporting year. 
Appendix C is a table of monthly billed water use for Cary/Apex for the 2018 reporting year from the Towns’ 
billing database. 
Appendix D is the performance indicator and water balance output from the Town of Cary’s AWWA M36 Water 
Audit analysis performed for fiscal year 2018.  The percentage non‐revenue water is used in the discharge report 
to determine Neuse Demand. 
Appendix E is a table of the actual discharge to the Cape Fear River Basin from Western Wake Regional Water 
Reclamation Facility (WWRWRF) and other discharges such as the Durham County Triangle Wastewater 
Treatment Plant.

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 2018, 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 15.9 mgd (51% of certificate limit) which occurred 
during June 2018. The peak month transfer from the Haw River basin to the Cape Fear River basin was 0.10 mgd 
(5% of certificate limit) which occurred during June 2018. 
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, 2018 through December 31, 2018 is found in Appendix A. 
The average daily withdrawal for the Towns was 23.0 mgd during 2018 (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 61 days during 
calendar year 2018.

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 for 3 days in 2018, as discussed in section 4.2.

Consumptive Use by Basin 
The average daily consumptive use was 15.0% for the period January 1, 2018 through December 31, 2018. 
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.

2018 20.0 3.0 15.0%

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 2018 was estimated based on the previous year’s 
water use in each basin as determined by billing records for Cary and Apex. 
During 2018, based on 2017 billing records, it was assumed that 32.6% of water use occurred in the Haw subbasin, 
1.4% of water use occurred in the Cape Fear subbasin, and 66.0% of water use occurred in the Neuse River 
subbasin. During 2019, based on 2018 billing records, it will be assumed that 33.6% of their water use will occur in 
the Haw subbasin, 1.4% of their water use will occur in the Cape Fear subbasin, and 65.0% 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 2018 calculations.

SECTION 4 
Discharge Report 
The following is addressed in this section as required by Condition 9 of the 2015 IBT certificate modified by the 
North Carolina EMC in March 2018, 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 value for 2016 was 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 2018.   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 2018 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 March 6th to 8th, 2018 to perform a 
repair on the Kit Creek Pump Station Force Main Air Release Valve.   
Figure 4‐1 below shows the Towns’ daily Cape Fear River Basin discharges from WWRWRF and to Durham County 
for 2018. Supporting data is found in Appendix E.

Discharge Compliance Evaluation

The Towns are in compliance with condition 9 of the 2015 IBT certificate modified by the North Carolina EMC in 
March 2018.  The Towns will continue to monitor required discharge and will comply with reporting 
requirements. 

If required in a future year, this section would discuss mitigation measures and temporary compliance solutions 
undertaken by the Towns of Cary and Apex in the prior calendar year, the estimated impact of each such 
measure, and all data supporting each estimated impact.

calendar year 2018. 
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 2018. 
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 2018. 
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

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 61 days during calendar year 2018.  
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 2018.
