Converting Sewer and Stormwater assets to Esri’s LGIM…Why, how and what did the City of Portland, ME get out of it?

Jessica Gooch – Asset Management TechnicianCity of Portland Maine, Water Resources Division

P O R T L A N D

Why did the City do this? Utilize the ELA that the City has with Esri

Leverage the LGIM and ArcGIS for Water Utilities tools – Editing, Networking, App Development

Standards, standards, standards Adhere to specific standards for both GIS and Sewer/Stormwater Utility standards

Protocols, SOPs and procedures Establish editing workflows, procedures and protocols to ensure timely data collection and integration

The City of Portland is an MS4 community (Municipal Separated Sewer System). The MS4 is a permit that we hold with the EPA concerning the separated stormwater system targeted to improve water quality by outreach, BMP’s, daily maintenance operations (mapping, evaluating the system, street sweeping, catch basin cleaning etc.) and inspections and assessments.

The City of Portland has a CMOM (Capacity, Management, Operations and Maintenance) plan that requires that the City have an Asset Management Plan for its sewer and stormwater assets.

EPA Administrative order to have an asset management plan which includes knowing where all of our sewer and stormwater assets are located, what condition they are in and have the ability to manage these assets long term

What We Need to Manage:

120 miles of Stormwater Pipe

120 miles of Combined Pipe

107 miles of Sanitary Sewer Pipe

9 Wastewater Pump Stations

15,000 Storm and Sewer Manholes and Catch Basins12 CSO Outfalls

The City needs to be able to maintain a desired level of service for what our sewer and stormwater assets need are and then provide those services at the lowest cost. In order to be able to do this we need to answer 2 questions first!!!

What does the City have for sewer and stormwater assets and where are they located?What condition are those assets in?

We cannot really answer the second question without fully answering the first!!!Once we have the answers to those two questions then we can begin to really utilize asset management as a tool for planning.

In order to get those two questions answered, the City needed a solution…and a little help from our friends…

P O R T L A N D

What is the Solution???Local Government Information Model and the Water Utility Network tools

The LGIM is a Geodatabase Schema based on an information model of GIS datasets, web services and maps designed to help Local Governments implement an ESRI based solution for their GIS Data

The Water Utility Network Editing Solution is designed for mapping technicians to manage water, sewer and stormwater network data

What do you get?Attribute Assistant Add-in Water Utility Network ToolsLocal Government GeodatabaseLocal Government toolboxWater Utility Network Editing MXDStandard set of Sewer and Stormwater Symbology

The Process

Review Design Migrate

The City decided to enlist the help and expertise of the ESRI team in Redland’s California to help us with the process of moving to the LGIM

Review Existing GIS Review Design Migrate

• GIS data is incomplete and has some inaccuracies • No standard editing workflows or protocols• Attributes were not always being populated• No standard process for tracking new projects and changes • CAD data process needed updating

• Need a process for auto-populating attributes• Facility ID’s, watersheds, to and from manholes etc.

• No editing tracking, no standard QAQC procedures• GIS data was not being checked against typical water utility rules

• Manholes and mains not connected, upstream vs. downstream elevations • Domains and feature classes did not adhere to standards required in the water utility world

• NASSCO (National Association of Sewer Service Companies)• No domains for fields that should have them

• GIS needs to be connected to other databases (CCTV, CMMS etc.)

Editing Tools

Data Reviewer

P O R T L A N D

Attribute AssistantWhat does it do, how does it work???• Used as part of our editing workflow• Populate attributes when you create new features or

modify existing features• Rules are be created that can sequentially number

features that are unique to that feature class – Facility ID

• Server or file geodatabase setup• Dynamic Value Table – where you set up the rules

• Value Methods – GENERATE_ID, INTERSECTING_FEATURE

• On Create, On Change, On Change Geometry, On Manual

• Generate ID Table – Where the sequential counter info is stored

P O R T L A N D

Attribute AssistantGenerate ID Table• Connected to the Dynamic Value Table• SEQCOUNTER – holds the number in the

sequence• Any rule with a [seq] will have a feature class

associated with it here

Water Utility Network Editing Tools

• Water Utility Network Editing Toolbar• Water Utility Network Reporting Toolbar• Water Utility Network Editing Construction

Tools

The Water Utility Network Editing solution includes 2 editing toolbars and a set of ArcMap construction tools that the City can now use as part of its editing workflow

P O R T L A N D

Water Utility Network Editing Tools

• Connect and disconnect geometric network features• Validate features – validates subtypes, attribute domains, geometric network rules, relationship rules• Connection checker – all junctions connect to an edge, all edges connect to another edge• Split lines at selected points• Merge geometric network lines• Create jump overs or jump unders for intersecting lines• Add laterals at connections or line locations• Connect selected point to closest existing point• Establish flow direction, established digitized flow direction, show/hide flow arrows• Flip selected

P O R T L A N D

Water Utility Network Editing Tools

• Run isolation traces – valves, upstream and downstream traces• Flow accumulation• Add/Remove a flag• Add/Remove a barrier• Profiling • Summary isolation trace• Summary flow accumulation • Change operable status of a valve• Clear trace results

P O R T L A N D

Water Utility Network Editing ToolsThe Water Utility Construction tools help to improve the editing experience when working with water utility data.

You can add connections and laterals along with additional point features such as valves and cleanouts. The tools allow you to draw laterals perpendicular to a main from a point.

You can add a point and split the line at the same time.

All of these tools came with the LGIM for Water Utility and will help to drive the City of Portland’s Asset Management program forward.
