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 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

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

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
