Plan Review

Part of Filterra’s operating procedure is to review all plans of our system to ensure best use and placement for your project. We respectfully require that you send plans and a completed Project Information Form to Filterra for review.

This review is to ensure that each Filterra system operates efficiently to maximize performance and minimize maintenance. Our staff looks for value engineering opportunities and will make every effort to review your plans within three days of receiving them.

Plan sheets or files (CAD, PDF or TIF format files) should include:

  • Cover sheet
  • Grading
  • Drainage areas/ Hydrology

  • Stormwater schedules
  • Filterra details
  • Landscaping
