source, reduce withdrawals from the source, and reduce the amount of treated effluent to
the receiving stream, which is a goal of the Clean Water Act under the National Pollutant
Discharge Elimination System (NPDES) program.

2.2.1 Existing Water System
The Town obtains its drinking water from Jordan Lake. The water is treated at the
Cary/Apex Water Treatment Plant (WTP), which is located in the Town of Apex’s
jurisdiction. Raw water from Jordan Lake is conveyed approximately 4 miles to the WTP,
which is located on Wimberly Road (State Route [SR] 1603). The WTP has a current capacity
of 40 MGD. To distribute water, the Town of Cary maintains approximately 103 miles of
transmission lines, with diameters ranging from 2 to 42 inches within the Town of
Morrisville. No pump stations or storage tanks are present in the Town (CH2M HILL, 2009).
Figure 2-3 illustrates the existing water infrastructure in the Town of Morrisville.
2.2.2
Future Water System
The Town of Cary developed its Water Distribution SystemMaster Plan (Water Plan) in June
2009 (CH2MHILL, 2009). This effort involved creating a new water distribution system model,
including the Town of Morrisville’s system. The Water Plan recommends improvements
outside of the Town to improve service to the Town’s existing and future residents.
Additionally, the plan recommends further demand studies and potential modification of
pressure zone boundaries and storage to improve system efficiency.
Future water lines are shown on Figure 2-3. Any future construction would occur under the
direction of the Town of Cary. A detailed explanation of proposed capital improvements is
presented in Appendix C. Exact locations of the proposed infrastructure will be determined
during development of the environmental documents, which will examine the direct
impacts of the infrastructure. However, general locations for the infrastructure are known
and supported by land use planning and population projections; therefore, SCI are
identifiable at this time.
The Cary/Apex WTP is being expanded to 56 MGD and a portion of the generated potable
water will serve Town of Morrisville’s residents. Construction is expected to be completed
in 2016 (Town of Cary, 2014b).
In 2013, the Town of Cary developed a Long-Range Water Resources Plan (LRWRP), which
will guide the development of water supply and resource management solutions that are
financially responsible and maintain a high quality of service for the Town of Cary’s
customers, which include the Town of Morrisville. The LRWRP takes a strategic long view,
through 2060, to meet the Town’s water resources challenges in a dynamic and holistic way,
through development of a Water Resources Portfolio. The Portfolio provides a mix of
practical strategies that the Town can apply to meet its water resources responsibilities by
implementing the right actions at the right time (CH2M HILL and Brown and Caldwell,
2013). The LRWRP identifies water supply and resource management options for
implementation.
