BACKFILL SIDES
The excess excavation along the outside perimeter of the storage basin can be backfilled once all of the AquaBlox
installed. Use sand or compactible-free draining material to backfill evenly on all sides to secure the AquaBlox
NOTE: Make sure to evenly distribute backfill material around the perimeter of the basin, working your way up to final
grade. This will prevent AquaBlox

STEP 10
INSTALL OVERFLOW (RAINWATER HARVESTING SYSTEMS)
The Rainwater Harvesting System requires an overflow to be installed in order to manage any excess water entering the
basin. The overflow should be located as high as possible in the storage basin in order to maximize the amount of water
storage. The overflow is installed by cutting a hole in the liner to the diameter of the male threads on the bulkhead adaptor
included in the overflow kit. The bulkhead can be installed into the liner with the rubber gasket located inside the storage
basin and the plastic gasket located on the outside of the storage basin liner. A small bead of silicone can be spread around
the rubber gasket where it meets the liner to help ensure a water-tight seal. Tighten down the large bulkhead nut being
careful to not over-tighten and crack the bulkhead. An adjustable overflow elbow is included with the overflow kit. Add Teflon
tape or silicone around the threads of the elbow and install into the bulkhead on the inside of the storage basin. This will
allow fine adjustment of the overflow height. Add Teflon tape or silicone around the threads of the PVC male pipe adaptor
and install into the bulkhead on the outside of the storage basin. PVC pipe can then be primed and glued into the overflow
