Enhancing CAD and GIS Standards for Water Distribution: Insights from New Jersey American Water

This presentation discusses the evolution of CAD and GIS standards employed by New Jersey American Water from pre-2005 to the present day. It outlines the processes for submitting drawings in AutoCAD and ArcGIS formats, highlighting how essential linework is extracted for SDW permit applications. With over 1,400 projects and a standardized procedure established, the benefits include easier compliance, clearer interpretation of drawings, and timely updates to regulatory submissions. This session provides practical guidelines for developers and engineers on using the updated standards efficiently.

  1. CAD Drawing Requirements Developer Services Summit November 16, 2010 Presented by Donna Short

  2. CAD The Past The Past – Pre 2005 • 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 CAD

  3. CAD The Past – 2005 to 2010 • 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. GIS

  4. 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. 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 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

  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 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

  7. 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

  8. 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

  9. Logistics • Standard is available for download from the American Water website:http://www.amwater.com/njaw/working-with-us/doing-business-with-us/developers-customer-resources.html • First glance for developers was made available November 2009 • Standard went into effect January 1, 2010

  10. 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
