1 APWA 2014 Congress August 17, 2014 Asset Management for Sanitary Sewer Systems - Beyond CMOM and Asset Management Portland named America s most livable city in Forbes One of the Where to Live NOW places in America -Outside Seventh Greenest City in the U.S. -Travel & Leisure America s Foodiest Small Town. -Bon Appetit Portland At a Glance Population of 66,363 Center of a 500,000 pop. metro area sq. mile area Council with manager and mayor First settled in 1633 Portland viewed from the air - Peninsula Portland viewed from the sea Casco Bay Portland viewed from the land - Old Port District 1

2 Portland s System 68 miles of Stormwater Pipe 107 miles of Sanitary Sewer Pipe 120 miles of Combined Pipe Nearly 15,000 other structures move sewage and stormwater through the system. System dates to 1850 Wastewater treatment plant built in 1979 In 1983 established a sewer fee No active treatment system for stormwater runoff State s largest CSO contributor City and Portland Water District share wastewater responsibilities A Daunting Problem CSO Consent Agreement with Maine DEP Phase I & II cost - $99 Million Phase III starting in $170 million of projects (15 years) A.O. with CMOM and asset management September 2012 EPA Issued Findings of Violation and Order of Compliance and Request for Information CMOM Corrective Action Plan High Flow Collection System Management Plan Emergency Response SSO Plan A Daunting Problem (cont d) Renewal of infrastructure has been minimal Estimated renewal needs of $4.5 million per year Organizational Challenges Information management (GIS, CCTV, work orders, etc.) Asset management Organizational structure Complex and compounding stormwater management 2

3 Progress and Solutions In 1991 Portland enters into a phased CSO Consent Agreement with Maine DEP Over 100 projects completed 11 of 43 overflows eliminated Reduced overflow volumes by 42% Separated over 20 miles of pipe Assessment Approach Structured conditions assessment Risk-based renewal planning Organizational changes Capisic Pond CSO Project CMOM Approach and Process Structured Assessment Collection System Modeled hydraulic capacity CCTV inspection data representative sample Risk-based assessment of renewal using GIS data Pump Stations Visual condition assessment of nine pump stations Equipment and maintenance records CMMS maintenance records data CMOM Approach and Process Risk Based Renewal Planning 3

7 Findings Infrastructure Assessment Minimal hydraulic capacity issues Condition better than anticipated Identified asset action level Immediate action High priority renewal Mid priority renewal Frequent assessment Regular motioning Sample Assessment Fair 34% Risk Based Renewal Planning Example $1,600 Recommended Franklin Curtis Estimated Annual Expenditure (Thousands) $1,400 $1,200 $1,000 $800 $600 $400 Annual average expenditure with existing pump stations = $416,000 Annual average expenditure with Franklin eliminated = $261,500 Annual average expenditure with Franklin and Curtis eliminated = $233,500 $200 $ Pump Station Risk Portland pump station risk 7

8 Findings Risk Based Renewal Planning Short Term Renewal Planning (FY15 to FY19) Immediate action High priority action CIP annual average cost Collection System : $1.1M Pump Stations : $0.67M Long Term Budget Planning (FY20 FY 50) Mid priority renewal Frequent assessment Regular motioning Sample Assessment CIP annual average cost Collection System : $3.2M Pump Stations : $0.416M Very Good or Good 56% Findings Management Framework Assessment Operations & maintenance ac vi es Refocused Reactive / Corrective Preventative Predictive Wastewater Ordinances and Program Improve operational efficiency History Practices Regulatory requirement Program development / implementation Staffing and Organiza onal Department of Public Services Increase efficiency Cost effectiveness Quality service to Public Meet regulatory / compliance requirements Next Steps Integrated planning Renewal plan budgeting Preventative and predictive maintenance Implement risk based asset management strategy Utilize CMMS Risk analysis 8
