Do you have data for tank buoyancy calculations?
The following table provides empty tank buoyancy information for Fuji Clean residential system models. As stated in the Fuji Clean Installation Manual, for uplift restraint in high groundwater sites we recommend:
a. Anchoring the tank using precast concrete anchors (deadman) and 1-inch galvanized coated strapping or equivalent. Set deadman 12" away from tank. Please do not use lifting lugs with turnbuckles to anchor tank as special fittings are required for this. Please contact Fuji Clean USA for additional details.
b. Pour concrete collar positioned just above tank mid-seam.
