S.A.W.
Significant progress toward identified funding structure
1. significant progress toward achieving the funding structure within 5 years
2. significant progress to mean the adoption of an initial rate increase to meet a minimum of 10 % of any gap in revenue needed to meet expenses

Cloud Based Data Collection Options
• Uses a mobile app to collect data
from any smart device
• ESRI cloud based application
• Cost per license: Varies based on
credits
• Best for project management and
tracking
• Uses a mobile app to collect data from
any smart device
• Trimble cloud based application
• Cost per license: $250/user per year
• Best for Data collection
Operations Dashboard
Other Data Collection Options
• We can also collect the data using a client’s existing
asset management software application
• Data is collected using the software’s app and saved
directly to the database
• No merge required
Sewer Televising Approaches
Clean to Televise Televise to Clean
Traditional method
Provides clearer picture of interior
Maintenance issues removed
Better view of structural issues
Assess current condition of pipe
Identify maintenance issues
Not all sewers require cleaning
Structural issues still identifiable
Sewer Televising
• Standard PDF reports and
videos
• ICOM3 software
• Autonomous SOLO robots for
8”-12” Sewer
• Multi-Sensor Inspection (MSI)
technology
• Do not provide cleaning, but will
partner with a cleaning
contractor on an as-needed
basis
• Standard PDF reports and
videos
• Cleaning is an option
• More competitive

• “Combines conventional qualitative CCTV with synchronized laser and sonar dimension information”
• Provides a “unique full 360° quantitative view of the pipeline”
• Uses 3D LIDAR and SONAR data to generate a 3D model
of the pipe and associated engineering reports
• Pipe factors: size, material
• Year installed
• Location
• Criticality factors
• Weights
depth, and condition (PACP rating)
• Assign
• such as:
• Location of sewer (under road, backyard, etc.)
• Criticality of segment to the rest of the system
• ADT of road (if in roadway right-of-way)
• PASER rating of road (if under roadway)
Data Mining - Pipes
• In general, 1950-1960s built, large diameter (>18”) RCP pipes appear to be in worst structural condition
• Consider inspecting other pipes with these characteristics

Moving Average to Predict Future and degrade to ‘End of Life’
System Deterioration Curve
In this community, we can expect manholes to last for an average of 110 years
System Deterioration Curve
Current System Avg = 1.13

Rehabilitation Necessary when Structural Rating = 4
~50 years
All the techniques (including deterioration & criticality) can be applied to vertical infrastructure
o Treatment plants
o Pumping Stations
o Municipal Buildings
GIS: Best for data storage and presentation
Data Accuracy: Include QA/QC procedures for updating GIS
Establish unique IDs
The End Product: Understand how the data being provided by contractors will be delivered.
Tools and Approaches: Various methods are being sold
Only a portion of Asset Management
Buyer beware
Staff Involvement: Gain institutional knowledge
Cooperation across department
Engage water system departments
The Human Element
Common sense validation
Time Commitment: What does it really take
• Asset Management is a lifestyle
• It is not a project with an end date
• To do Asset Management well, will take time
• It involves significant data requiring data management techniques
• Better tools are being develop to make better decisions
• When deciding on “tools” to use -- understand what you get
