Abstract: A water separating residue filtration unit has an outer container has container walls surrounding a container floor. A screen is located within the container, the screen having a screen floor supported above the container floor thereby defining an inner void between the screen floor and the container floor and at least one drain drains from the inner void and an exterior of the container. A fabric filtration liner covers the screen. Non-destructive high-pressure water excavation residual liquid slurry may be pumped into the unit, allowed to settle such that water filters therefrom through the fabric filtration liner and the screen whereafter the unit having residual content therein may be transported for dumping.
