Streambed Construction; Pv1700 Pump Vault Installation - Atlantic PV1700 Manuel Du Produit

Streambed Construction

The less the water level in the basin drops as the pump turns on and the stream fills, the better
for proper function. Proper streambed construction can reduce the amount of water needed for
this transition.
Since transitional volume is determined by how high the rock extends above the liner at the
spillways, 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.

Below is an example of improper streambed construction. Stone, gravel and foam can be
combined to make a barrier and create a waterfall, but that barrier will never be watertight.
When the pump is turned off, the water will always drain down to the highest point of the
liner. Improper construction greatly increases the amount of transitional water.
