Secondary and Cumulative Impacts Master Management Plan - 2014

SECTION 2 Background and Description of Infrastructure Master Plans

As of April 3, 2006, the Town of Cary owns and operates the water and wastewater infrastructure assets within the Town of Morrisville’s jurisdiction. As such, the Town of Morrisville has adopted the Town of Cary’s water and sanitary sewer standards. This section reviews the capital improvements planned within the Town’s jurisdiction. Appendix C includes the Town of Cary’s Capital Improvements Plan (CIP) regarding water and wastewater infrastructure planned for the Town of Morrisville. The Town has a CIP for roadways, also included in Appendix C; this CIP is based on the Town’s Transportation Plan, which identifies future transportation corridors and roadway improvements. 2.1 Wastewater 2.1.1 Existing Wastewater System The wastewater collection and treatment system for the Town consists of gravity lines, pumping stations, and force mains conveying flows to the North Cary Water Reclamation Facility (WRF), which discharges to Crabtree Creek; and the Western Wake Regional WRF (WWRWRF), which discharges to the Cape Fear River. The system serves residential, commercial, industrial, and institutional customers. The Town’s industrial community includes several major employers, , including Lenovo, Tekalec, and other business and manufacturing uses in Perimeter Park and Southpark business parks. There are also several shopping centers. Institutional customers include several schools (two public elementary schools, private elementary schools, vocational schools) and the Town of Morrisville municipal facilities located at several sites. A major campus of Wake Technical Community College is scheduled to begin construction in 2015. Numerous drainage basins exist within the Town. Sewer lines generally flow by gravity, following the natural drainage, until they reach the North Cary WRF or a point where they are pumped out of the basin toward the North Cary WRF or to the WWRWRF. There are 21 subbasins served by gravity or pump stations. The collection system within the Town of Morrisville Planning Area consists of more than 86 miles of gravity sewer and 4 miles of force mains, as well as 12 pumping stations. Figure 2-1 illustrates the location of existing wastewater infrastructure (Town of Cary, 2013). 2.1.2 Future Wastewater System The Town of Cary’s Wastewater Collection Master Plan was updated in 2013 with a focus on addressing challenges posed by the merged collection system. The Plan recommended increasing the delivery capacity in the York Interceptor and at the Aviation Parkway Pump Station, as well as making other recommendations for outside of the Town of Morrisville to ultimately improve system efficiency (Hazen and Sawyer, 2013). Several projects are being pursued by the Town of Cary, in the service area previously owned by the Town of
