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

System Deterioration Curve

In this community, we can expect manholes to last for an average of 110 years

~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
