Boise, ID Lava Percolation Pond
The excavator for this project recognized the potential for the underlying lava flow on the site to function as a percolation pond. After mechanical excavation, there was a remaining layer of dirt and clay covering the 9000 sq/ft area. This sediment needed to be removed to allow for proper drainage. NG Hydrovac was called in and was able to remove all the sediment from the entire surface over four days. The site subsequently passed city inspection and the project was able to move forward on schedule. This job highlights one of the great qualities of hydrovac; Flexibility. While largely used for potholing and safely excavating around utilities, there is a huge range of possibilities for hydrovac trucks on most sites. Any situation where large quantities of material or water need to be removed and transported off-site, but mechanical digging is too dangerous, unable to reach, or simply isn’t practical, a hydrovac will almost certainly save time and money. This contractor crafted a unique solution to a problem by using the lava for water percolation, and the key to making it all work was NG Hydrovac’s unique ability to remove sediment from the complex topography of the lava. Something that would have been nearly impossible by any other means.
