WWTP Surveying

City of Mackinac Island
Mackinac Island, MI

Project Highlights

Project Summary

The City of Mackinac Island had an undersized wastewater treatment facility (WWTP) that also experienced fluctuations in flows throughout the year. F&V completed an evaluation of the island’s existing wastewater treatment facilities identifying needs and prioritized improvements. A survey of the WWTP building was required to complete designs and plans for improvements to increase wastewater treatment plant capacity.

F&V’s survey team utilized every item in its toolbox to reduce surveying time, save field work hours and costs, and provide more accurate data. LiDAR scanning was a game-changer surveying the Control Building’s existing piping and equipment which was difficult to access. The lightweight laser scanner made it easy for our survey team to carry – especially with no car access on the island.

The 3D laser scanning software eliminated errors in as-builts, saving time and costs from having staff going back to the site and remeasuring all the pipes, bends, and connections by hand. As a result of the survey, F&V was able to complete a master plan in early 2022 recommending the Moving Bed Biofilm Reactor (MBBR) alternative improvement.
