Utilities Goals

The Problem

Project identification by political and department whim

Maintenance identification by reactive measures

Subjective vs. quantitative decision making

The Justification

Improve decision making

Improve reliability of assets and customer deliverables

Improve forecasting, budgeting, and expenditures

Coldwater Board of Public

Utilities Goals

The Approach

Holistic integration of infrastructure assets

Engineering driven

Quantitative

The Challenge

Aligning priorities

Aligning budgets

Dynamic systems

System Background

System has historical infiltration issues with significant seasonal increase

Average daily flow exceeding WWTP capacity

Previous I/I projects did not address the issues

S2 Grant Project(s)

The Board applied for, and obtained, two S2

grants for $1 million

Grants covered:

GIS

Flow monitoring

Hydraulic modeling

SSES

SRF Project Plan Approach

Used a phased flow monitoring program to find

the subdistricts with excessive infiltration

Performed a comprehensive SSES in those

areas to locate infiltration sources

Identify SRF eligible projects; capacity issues

directly related to excessive infiltration

Flow Monitoring (Phase I)

Phase I Study Results

Primary issue is high

groundwater/permeable

soils

Phase I issue was

excessive infiltration

along Washington and

Sprague Streets

Phase 1 Construction

Phase 1 Results

Flows reduced by 20%

Estimated reduction of 300 gpm of I/I

Total removal estimated over 20 years is 3.1

billion gallons

Phase II

Despite large reduction in flows, still noticed a

significant rise in the spring

Only during high groundwater periods

Flow Monitoring (Phase II)

Phase II Results

Large drop in flows between two meters along

the main interceptor

SSES showed excessive infiltration along Morse

and Montgomery Streets

State Street Pump Station undersized and at the

end of its useful life.

Phase II Projects

CIPP Montgomery and Morse Street sewer

Replace State Street pump station

Scheduled for construction in 2014.

Other Issues Identified

SSES identified several deficiencies that were

not SRF eligible

Manholes, sewer mains, and pump stations

How do we document and address those

issues?

Asset Management Implemented

System Maps were updated using GIS

Condition assessment Completed and

Documented

Prioritized projects based on Risk

Plan Developed

Next Steps

Additional TV and manhole inspections

System Wide Comprehensive asset

management plan

Integrate WWTP into GIS

Why Asset Management?

Plan for future capital improvements

Identify problems before they become emergencies

Quantify systems

“Put first things first”

The future

Continuous reassessment

Continuous modeling

Integration of IT/OT and data applications
