Rainwater Tank Installation Support

• Excavate to the required depth plus 75mm (or more if required to achieve a fall from gutter height) and then back-fill with a layer of 10mm-12mm gravel or screenings.  The tank will then be placed directly onto this level land.
• Ensure the gutter outlet is above the tank inlet.
• Check delivery access with Ri-Industries.
• A minimum height clearance of 8 metres is required when unloading.
• 4.7 metres is needed for the truck to pass under trees and overhead power lines.
• 4 metres clearance is required between gate posts.
• Please highlight the position of any underground drains or cables.Trucks will not drive over any concrete or sealed areas without indemnity being signed (including all foundations).
•  Please ensure the unloading site is level.
•  Ri-Industries strongly recommends your tank not be left empty for extended periods.
•  If any tank is partially buried more than 900mm in the ground there is a possibility that it may float unless precautions are taken. We suggest that the tank is filled with water immediately after placement to at least ground level, until the back-fill soil has compacted.
•  If you have any doubts regarding your installation a site inspection can be arranged.

Please also note that:

• Each above ground tank is painted and includes a 75mm diameter drain outlet made of brass. The overflow is ready to take a 90mm PVC stormwater pipe.  Male brass fittings can be fitted in the tank depending on customer requirements eg. for fire fighting purposes.
• Underground rainwater tanks can be installed down to a maximum of 2 metres below the ground but this requires riser pipes to allow access at ground level.
• Please Note : Ri-Industries advises that all underground tanks are filled at least 50%-75% with water in all chambers to stop floatation.
