Dewatering 2/3

е:

After rough grading the pond we were asked to come back and pump out any water that had collected over the summer. Another contractor had to come in and install the last few peices of inlet pipe below the current water level. In this video you will see how we filled the sump hole with water so that no sediment would be pulled in. This was critical as we were pumping directly into a manhole (and thus into a storm drain).
