Installation Location and Certification 

These tanks are not designed for vehicle loads and shall be located no closer than 1.50m to a driveway, road 
frontage or a building. If for any reason the tank is located where vehicle traffic may drive over the tank or 
approach closer than 1.50m, or where it may be trampled on by farm stock then the tank should be protected 
by a concrete slab designed to support these loads. Surface water must also be diverted from flowing into the 
installation. 

Installation must  be  certified  to  AS/NZS  1547:2012,  the  certificate to  be  issued  and  held  by  the  regulatory 
authority. 

High Water Table Installations 

All tanks have been engineered and designed with support ribbing for maximum strength, in accordance with 
the NZC 3604. Clauses B1 and B2 for structure and durability, to withstand any hydraulic pressures, both lateral 
and uplift, created by high water table conditions, even when the tanks are completely empty at install stage. 

As per the NaturalFlow Systems installation instructions, in these conditions, tanks must be anchored in with 
concrete around base, as per the installation instructions, to height as specified.
