The NC Center for Geographic Information and Analysis developed the GIS data set, Type A Current Public Water Systems, as mapped by contractors to the NC Rural Center (engineering firms McGill & Associates and Hobbs, Upchurch & Associates) during 2004, 2005, and 2006 to facilitate planning, siting and impact analysis in the 100 individual counties of North Carolina. This file enables the user to make various county-level determinations when used in conjunction with other data layers. "Current" in the title Type A Current Public Wate Systems refers to the most recent year of data the water system owner had that represented a full year. The survey was in 2004, so this data would normally have been for calendar year 2003.
The purpose of this data set is to inform users of key information about public water systems in North Carolina, with particular focus on system size and growth, water usage, water treatment, and capital improvement needs of the systems.
Data limitations: For security reasons, Fort Bragg did not provide service area boundaries; therefore the entire military base was used as the service area boundary. Wake Forest, Knightdale, Wendell, and Zebulon were individual service areas when the data was collected, and this is reflected in the data. However, these sytems have now merged with the Raleigh system. This change will be reflected in future updates, as they occur. Service areas with only future boundaries have system IDs with no other detailed information associated since the systems do not yet exist in mature form. Some service areas have limited information in the corresponding tabular data, either in the form of zero values or missing records. These systems either refused to provide the data or are so new that much of the historical data requested does not yet exist. Revisions and updates to this layer include: 1.) March 2007 version was the first recorded release of this data.

This data was collected by engineering firms McGill & Associates and Hobbs, Upchurch & Associates by survey and site visit.
Using ESRI's ARC/INFO GIS software, the data set was built for arc and polygon topology using the "build" command. The data set was then cleaned with a fuzzy tolerance of 10 meters. Topology has not been edited since the last build or clean.
This data layer represents the Type A Current Public Water Systems of all counties in North Carolina.
System boundaries were reviewed by CGIA for accuracy and modified as needed.
Paper maps on which 1998 service area boundaries were plotted.
The contractors collected graphic data from water and sewer system managers, and collected numeric data from water, sewer, and stormwater system managers throughout North Carolina. Graphic data was collected in one of two ways. If the system of interest was evaluated during the prior system survey of 1998, the new graphic data was collected by forwarding or delivering to each system manager a map of the water or sewer system pipes as they existed in 1998, having the system manager adjust system boundaries to reflect current and expected future boundaries, and making those edits to the 1998 polygons. If the system of interest was not evaluated in the 1998 survey, a map of the current and expected future boundaries of the system was requested from the system manager. In both cases, the current and expected future boundaries of the water or sewer system were ultimately digitized from the data provided by the system manager. In some cases, system managers reported no change in current or expected future system boundaries, and in those cases the resulting polygons are identical to those produced from the 1998 survey. For this study, current system boundaries were defined as those boundaries in existence at the time of the survey (2004). Future system boundaries were defined as the boundaries expected to exist in the year 2010. Numeric data was collected by crafting a table structure for the required data, forwarding a paper questionnaire developed from this data structure to each system manager, collecting that data as a written response to the questionnaire (via return mail or face-to-face meeting), then entering this data into the table structure.

AMEC Earth and Environmental, Inc. of North Carolina (AMEC) took responsibility for managing the data structure, data connectivity, and quality control aspects of the graphic and numeric data generated for this project. AMEC integrated individual polygons into a statewide coverage of systems of various types, and also performed quality control reviews on numeric data and data ranges for numeric fields. AMEC identified disconnections between polygons and the underlying tabular data and worked with the other contractors and CGIA to rectify these disconnects. Using linear multivariate regression techniques, AMEC estimated current and future capital improvement needs for systems which had no published capital improvement plans.
