Wastewater Membrane Bioreactor Wind Retrofit

Marco Island, Florida

This project includes the design and preparation of construction plans and specifications, as well as bid phase and construction phase services for structural fortifications to the existing structure housing the City of Marco Island’s wastewater membrane bioreactor (MBR) located at the reclaimed water production facility. This is a FEMA-sponsored Hazard Mitigation Grant Program (HMGP) project. The goal of the project is to fortify the MBR facility against wind damage. The project consists of protecting the existing structure by installing wall enclosures to protect existing pump and filtration equipment, providing impact resistant overhead rolldown doors, retrofitting the existing roof (if necessary), improving ventilation within the structure, providing lighting required by code, and improving odor control in the enclosed space. Wind protection will be provided on openings such as vents, louvers, and exhaust fans. Design for improvements will comply with the applicable sections of the current Florida Building Code (FBC) at the time of design, and components will meet current wind and impact standards. Because wastewater treatment plants are classified as critical facilities (Risk Category IV) in the FBC, the new enclosures will be designed to the current FBC wind speed requirements of 182 mph wind speed at this location.
