The Past 2005 to 2010
CAD

• Drawings are submitted to New Jersey American in
  AutoCAD format
• New Jersey American Water extracts needed
  linework from Developers 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

The Past 2005 to 2010 (contd)

• 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
The Present

• 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 Developers 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

6
The Present (continued)

• 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 Waters 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

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

• 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
