The Past
Drawings were submitted to New Jersey American Water in AutoCAD format
New Jersey American Water extracted needed linework from Developer’s drawing and added them to the distribution maps in AutoCAD format
New Jersey American Water submitted revised distribution maps in AutoCAD format to NJDEP for SDW permits
The Past – Pre 2005CAD
CAD

Drawings are submitted to New Jersey American in AutoCAD format
New Jersey American Water extracts needed linework from Developer’s drawing and adds them to the distribution maps in ArcGIS format
For projects requiring individual SDW permit applications, New Jersey American Water extracts specific project linework and provides data in ArcGIS format for submittal to NJDEP
For project in areas under Master Permits, New Jersey American Water provides an annual update to NJDEP of all proposed projects – list must match the NJDEP’s list of PAW projects.
The Past – 2005 to 2010CAD

The Past – 2005 to 2010 (cont’d)
Current Process in place since 2005● Have logged over 1400 projects
Over 610 Different Applicants Utilizing over 575 different Engineers
Resulting Issues● Over 1400 projects to track● Countless numbers of CAD standards● Time consuming process, regardless of SDW permit status
5
Drawings are submitted to New Jersey American Water in a standard New Jersey American Water AutoCAD format
New Jersey American Water extracts needed linework from Developer’s CAD drawing and adds to the distribution network in ArcGIS format
New Jersey American Water exports data from GIS for SDW permit submittals, Individual or Master permits
The Present
6
Developers/Engineers are able to draft plans utilizing their current CAD standards or directly in New Jersey American Water standard template
New Jersey American Water provides a drawing template in AutoCAD format along with step-by-step instructions for converting objects from original layering standard into New Jersey American Water’s layering standard
Standard block symbols are utilized and provided in template file
A “scaled down” version of the original design is submitted to New Jersey American Water for approval
The Present (continued)

Benefits
All projects submitted to New Jersey American Water are in the same format
GIS essential objects are layered so that they are easily identified and separated from nonessential GIS objects
Conversion process is easy for developers and/or engineers to follow
Allows for more timely updates to GIS and thus more timely submissions to NJDEP

Details of the Standard Standard CAD drawing
template with layering convention and blocks included
Attributed block symbols provided
Layering standard based on the National CAD Standard Format
Layer colors based on the One Call Format for Utilities Step-by-step guideline for converting existing CAD drawings
into New Jersey American Water Standard template file

First glance for developers was made available November 2009
Standard went into effect January 1, 2010

Results We have seen varying levels of compliance with standard
Block symbols Layers Spatial accuracy
Time to input data from CAD files has decreased dramatically Drawings are easier to interpret Layering allows editors to grab only what they need Consistent symbology eliminates guesswork Act as training sessions for new employees
