The following are installation procedures recommended for precast concrete tanks.
- The tank should not be installed where surface water will pool such as low areas or near eaves downspout.
- The excavation should be at least 6" larger than the tank on all sides.
- The bottom of the excavation to be level and free from rocks and lumps which may cause damage to the concrete tank. A 4" layer of fine sand is recommended for the bottom of the excavation.
- After the tank has been set in the hole, the excavation should be backfilled with sand or gravel at least around the tank. Heavy clay as backfill is not recommended.
- The burial depths are as stated on the CSA certification tag attached to each tank.
- No vehicle should be driven over the installed concrete tank at any time. Tanks are not designed for live loads.
- All concrete tanks manufactured by Pre-Con Limited are wet cast with monolithic wall and floor construction.

A permit must be obtained from the Department in all cases either by the owner or the contractor.
