Problem: 

The containment area did not drain properly and the holding pond was at a higher elevation which further complicated the drainage issue.

Solution: 

We regraded the containment floor and installed subsurface drainage with a catch basin.  An explosion proof pump was installed to lift the water.  Excess material from the regrading was used to raise the berm height, then geotextile and rock was installed with our special application process without particle separation to prevent erosion.
