Overcoming Barriers to Developing an Asset Management Program

Aging infrastructure is a significant concern for the utilities, service districts, municipalities, and counties responsible for operating and maintaining stormwater, wastewater, and drinking water systems throughout the United States. Utilities have developed and implemented formal asset management programs (AMPs) to reduce unexpected, expensive, and reactive repairs and increase overall system performance. Despite the demonstrated benefits of AMP implementation, the challenges and barriers that can come with developing a new AMP — or integrating existing asset management tools into a formal, centralized AMP — can seem overwhelming to utilities beginning the process. In response, EPA developed the paper “Asset Management Programs for Stormwater and Wastewater Systems: Overcoming Barriers to Development and Implementation.” This paper presents information obtained from case studies and input from utilities at various stages of AMP implementation.

Asset Management in NPDES Permits

Municipalities across the country are facing the challenging obligation to manage their aging sewer and stormwater systems at a time of urban population growth, more stringent water quality protection requirements, and increased exposure to climate change-related risks. At the same time, it has become more difficult for many municipalities to secure new funding for infrastructure improvements or replacement, or even to maintain existing funding levels. Asset management planning is a proven tool for maintaining and elevating levels of service for wastewater and stormwater systems and planning system renewal and upgrades.

The National Pollutant Discharge Elimination System regulates point sources that discharge pollutants into water of the U.S. and serves to standardize practices associated with operating & maintaining both sewer and stormwater collection systems.

Incorporating Asset Management Planning Provisions into NPDES Permits (PDF) (10 pp, 560K) outlines the benefits and basis for addressing asset management in NPDES permits, then goes on to suggest potential language and implementation practices for incorporation into permits.

Case Studies

To provide context for current asset management implementation being conducted across the country, EPA Region 9 has compiled a handful of case studies on municipalities currently in various stages of implementing asset management practices:
