An Application in GIS for a Sanitary Sewer Overflow Emergency Response Program Mike Pritchard Penn State MGIS Capstone Project Advisor: Jan Oliver Wallgrun

Key Points of Discussion Project background Proposed goals Project needs Literature review Proposed methodology Deliverables and timeline

Medina County Sanitary Engineer (MCSE) Sanitary Sewer System Project Background

Sewer district 500 with trunk sewer highlighted

Motivation for Project MCSE Response Plan Developed GIS Sanitary trunk sewer collapse in 2009 Response plan to Sanitary Sewer Overflow (SSO) How to best utilize GIS in emergency situations

Proposed Goals Application in GIS to use with existing web based GIS

GIS Generated Report Easy to understand All pertinent info Printer friendly

GIS Tool to Generate Report Potential geoprocessing service Python and model builder Accompanying map of incident area

MCSE Needs Sanitary network info related to location of SSO Repair options Customers concerns Necessary/unusual equipment Source: Source: long-does-take-dig-track_hoe.jpg long-does-take-dig-track_hoe.jpg

MCSE Needs Continued Environmental risks Emergency Contacts Regulatory Agencies Government and Community Leaders Source:

Literature Review What is an SSO A discharge of untreated sanitary sewage from the result of a broken pipe, equipment failure, or overload on the system [1] Why Have an effective emergency response plan Define how to respond, control, report and mitigate the event Enhance the protection of public health and the environment Provide compliance with regulations and permits Maintain trust with the public, the regulatory agencies and the non- governmental organizations Minimize the wastewater agency’s exposure and liability from claims, enforcement, or litigation

Involved Organizations EPA SSO Toolbox Important information to include in plan SSO identification protocols Hydraulic modeling to understand effects of SSO

Case studies of effective plans related to SSO’s City of Delmar, CA [4]: Sanitary Management Plan Greenwood County, SC [5]: Comprehensive Management, Operations, and Maintenance Plan DeKalb County, GA [6]: SSO Contingency and Emergency Response Plan

Approach & Methodolgy 1.Design SSO report to be generated from GIS 2.Build GIS to run report as a service through ArcGIS Server (python and model builder) 3.Simulate SSO with potential users

Sketch of Potential Generated Report  Organized based on response plan categories  Static and dynamic data  Overview map to provide general location  One page (may change in design)

Widget toolbar on web map and sketch of potential workflow

User Testing Flexible based on project timeline Simulate an SSO event Actual user testing Feedback Report

Project Deliverables 1.GIS generated report with simulated data from SSO 2.Geoprocessing script with accompanying screenshots (or video) of simulated SSO 3.Presentation of paper

Timeline January – February (~6 Weeks) Design SSO report February – March (~6 Weeks) Build GIS tool to generate report and accompanying maps April (~4 Weeks) User testing May – September Finalize report and presentation
