Manufactured Treatment Devices (MTDs), similar to non-proprietary stormwater BMPs, must be maintained to perform as intended. However, majority of effort and focus is placed upon the initial design and construction of stormwater treatment facilities, with little thought as to how these systems will be maintained long-term. The property owner is typically left responsible for the consequences of decisions made by others during the design and construction phases, nearly all of whom have moved on to new projects after the construction phase of the project is concluded.

As our industry evolves, civil engineers are now placing more importance on the long-term maintenance costs associated with MTDs. To serve the best interest of their clients, not only does the specifying engineer have the responsibility to select and design the stormwater BMP that meets the site’s structural and regulatory requirements, they also have a responsibility to consider long-term cost of ownership as well as initial capital costs. Reviewing access constraints, placement of the MTD, maintenance onsite logistics, materials needed, and disposal logistics are crucial in the selection and design of MTD’s.

This presentation aims to help engineers better understand how to design MTD’s with maintenance in mind, the integration of O&M information into the BMP selection process and the factors that impact MTD maintenance cost.

Learning Objectives:

• Review Design Considerations for Manufactured Treatment Devices
• Learn about what is required at a maintenance event
• What is involved with post maintenance disposal
