Wastewater collection and transport systems are critical components of a community’s infrastructure. Effective management of these systems minimizes costs and optimizes treatment efficiency by reducing infiltration and inflow (I/I), controlling pump station operations, eliminating overflows, and replacing aging or undersized pipes before they become problematic.

Typical challenges that keep collection system operators and managers awake at night may include:

  • Structural, operational, and maintenance issues that can increase sewer deterioration rates
  • Depleted pipe capacity caused by blockages or extraneous flows
  • Having the right amount of funding in-place and on-time for needed rehabilitation
  • Routine sewer maintenance needs for silt, debris, and grease buildup throughout the system
  • Force main failures
  • Existing, new, and hard to identify or correct I/I sources
  • Ragging or failure of pumps and appropriate backup pumping operations

There are several means and methods you can implement to help control the health of your collection system. These include:

  • Developing or updating CMOM or O&M plans to document resource needs and standard operating procedures
  • Maintaining or beginning a fats, oils, and grease (FOG) management and grease trap inspection program
  • Pipeline cleaning and inspection on a prioritized and routine basis
  • Performing a system criticality ranking by general location, basin, and asset to aid in prioritizing work assignments and projects
  • Tracking of high complaint areas to understand where problem areas are
  • Implementing an asset management program
  • Tracking local and federal funding opportunities and application schedules
  • Developing a routine I/I assessment and implementation schedule
  • Utilizing new scanning or scouting tools for blockages and sewer leaks
  • Routine and prioritized cleaning of catch basins, grease trap interceptors, or other treatment systems especially in combined systems
  • Addressing private I/I sources through public education and understanding of available solutions
