For Larger Basin Volumes
For installations where a larger basin volume or a deeper basin is required,
Atlantic offers a Pump Vault Extension for both the PV7500 and
PV15000 to create multi-layer reservoirs. Each additional
layer of Eco-Blox increases the depth of your excavation
by 171/2”; use one Extension for each
additional layer.
Streambed Construction
The less the water level in the basin drops as the pump turns on and the stream fills, the smaller
the reservoir can be. Proper streambed construction can reduce the amount of water needed.
Since transitional volume is determined by how high the spillway stones extends above the
liner, minimizing that height reduces the amount of water necessary to fill the streambed. The
drawings to the right display two examples of proper streambed construction to keep the
transitional water to a maximum of 3-4” in depth.
