1. STORMWATER UTILITY MANAGEMENT SYSTEM (SUMS) GIS Application with Web Service Data Access

2. Introduction – The Problem Stormwater utilities are unique Runoff can’t be measured Must be defensible Impervious area is usually the basis for billing 84% of ~1,500 Surveyed* Billing for Stormwater 71% Included with other utility bill** Difficult to visualize Difficult to manage related information * 2013 Study by WKU** 2014 Study by Black & Veatch

3. Application Design – The Solution ESRI GIS-based solution Easy to update and review impervious area Easy to account for and update every service area parcel Easy to store related documents and credits Configurable as environment changes Web-based access Reduce customer service calls to technical team Integrates directly with billing system

4. Stormwater Utility Management System (SUMS) Desktop Extension – Toolbars and Tools SUMS Editing Toolbar SUMS Management Toolbar

5. SUMS Editing Toolbar SUMS Tools Split feature Remove parcel from SUMS Group Assign Parcel to SUMS Group Remove impervious area from Parcel Assign Impervious Area to Parcel

6. SUMS Management Toolbar SUMS Tools SUMS Management Parcel Search Parcel Information Premise Search Premise Information

7. The Process 1. Customize Extension 2. Install Extension 3. Load and Configure GIS Layers 4. Configure Billing System Integration 5. Prepare SUMS Data Linkage a. Associate Impervious Areas to Parcels b. Associate Parcels to SUMS Groups c. Associate SUMS Groups to Billing System 6. Train Users

8. Data Entities and Relationships

9. Application Constructs SUMS Table The “glue” that associates the key objects Collects objects together for integration Links Table Premise is the main billing feature Some accounts have multiple premises Can assign partial ERU’s to each Used to detect changes in Billing System Allows user to synchronize between SUMS and the Billing System

10. Demonstration Scenario #1: Build new SUMS Group Assign impervious area to parcel Assign parcel to group Review parcel information

11. Demonstration Scenario #2: Review and Enhance SUMS Group Associate Billing System link Links tab and Premise tabs Add Credit to SUMS Group Add Document to SUMS Group Print SUMS Group exhibit

12. Billing System Integration - Options Direct – Read / Write Optimal – if security can be addressed Difficult to gain this permission Direct – Read-only Less vulnerable, still difficult to secure Export / Download Static data - you don’t have the data you need Web Services Database Access Excellent compromise

15. Web Services Database Access Windows Communication Foundation (WCF) Easy to define for hosting Stable and straightforward programming Can secure access By IP domain, by user, etc. Don’t need to be concerned about other access Very little is exposed Back-end changes easily addressed at server Publisher controls the version of the data Live, week-old, month-old, your choice
