SAW: Ready, Set, GO!

First round of grant recipients have

gone more than a full year (less than

2 years left!)

A lot of data collection required –

how can we get it all done in time?

Still Waiting?

Only two rounds in so far

Stormwater AMPs: $116 million

Stormwater Mgt. Plans: $26 million

Vast majority of SAW work has yet

to be awarded or contracted

This is NOT a Master Plan

Conventional Master Plan

Identify major problems

Develop CIP

Represents one point in time

Static document: sits on shelf

Updated every 20 or so years

Asset Management Plan (SAW)

Identifies condition of all assets

Develop Cost Structure

Continuous process

Integrated with GIS and CCMMS

Continuously updated

Ultimate Goal

Key Components

Smart, targeted physical evaluation

of assets

Modeling (optional)

Marrying the hard assets (pipes and

manholes) with the soft assets

(ponds, channels, BMPs)

Compelling case for local funding

Sewer Televising Strategy

Good cross section of sewer

ages and sizes

County drains (enclosed

systems)

Adequate sampling of system

TELEVISE FIRST strategy

Televise to Clean

• Conventional practice is

“Cleaning to Televise”

• Most sewers are self cleaning

and do not need to be cleaned

in order to be televised

• Televise as much sewer as

possible

• Flag the segments that were

unable to be assessed

Multi-Sensor Inspection (MSI)

• “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

Future Funding for Stormwater

• Reviewing local storm water

budgets:

• Most programs are covered by

injections from the General Fund

• Budgets often cover only major

repair projects (i.e. County Drain

projects)

• Little to no funding for

preventative maintenance

• Over-reliance on grants

• Like wastewater, stormwater needs a long term view of

the impact of O&M

• Without an increase in funding, systems WILL fail

• Asset Management Plan will visualize this

Stormwater SAW Recap

Critical to embrace new methods to

collect data in field (tablet-to-GIS)

Televise first (CCTV strategy)

Develop a case for dedicated

funding, and leverage the Asset

Management Plan to make it

compelling
