Gravel-Filled Reservoirs; Larger Basins - Atlantic PV1700 Manual Del Producto

Gravel-Filled Reservoirs

Because Eco-Blox are 96% void space, they allow the reservoir to be dug to just the size
required for the water volume needed. Backfilling with gravel fills 65% of the reservoir
with stone, leaving only the 35% that remains between the stones available for water
storage. This means that a gravel-filled basin will need to be three times larger than an
Eco-Blox basin to hold the same volume of water. That's a lot more time, excavation,
additional soil removed, additional gravel to fill the hole, labor costs and cleanup.
For Larger Basin Volumes
For installations where a larger basin volume or a deeper basin is required, Atlantic offers
Pump Vault Extensions for both the PV1800 and PV2300. Each additional layer of Eco-Blox
increases the depth of your excavation by 171/ 2 "; use one Extension for each additional layer.
