The installation of one or more prefabricated drains beneath the surface of sediment in a sediment pond utilizing suction or a vacuum to withdraw water from the sediment material to lower the water level down to the level of the prefabricated drains below the pond surface. Dewatering may be coupled with imparting vibrations to the material to further promote both additional dewatering and compaction of the sediment material in the pond. A suitably graded bottom ash, fly ash, sand or large-diameter-solid particle or sediment layer may be added on top of the horizontal drains to enhance dewatering of finer sediment material.

A mobile fabrication solution for onsite assemblage of earth drains for ground stabilization that includes a despooling carousel for uncoiling corrugated tubing from a stock supply, and for feeding the stock tubing into an extrusion head unit. The head unit contains counter-rotating wheels that grip and drive the tubing out through a collet into a filter sock and into a collection trough. One end of a stock supply of fabric filter sock is attached to the collet exteriorly of the head unit to the collet and is unrolled along the trough. When the corrugated tubing is ejected it fills the sock within the trough and may be cut to the desired length onsite, eliminating waste.

An apparatus for forming a water storage material from a biomass input material using supercritical or subcritical fluid processing, the water storage material capable of absorbing a liquid and releasing the liquid. The apparatus utilizes supercritical fluid processing, subcritical fluid processing, charring, or a combination thereof. The apparatus includes a controller configured to control the apparatus. The apparatus further including a processing station configured to hold the biomass input material, and to use the biomass input material for processing into the water storage material.

A leaching tube includes a tube base for burial in the earth to disperse or gather liquids, the tube base having a semi-rigid spiral, or helical, form with spiral, or helical, ribs, and spiral, or helical, openings along the length of the tube, a water permeable covering wrapped around the tube base, and a vertical frame inside the tube. The frame is a pipe frame that supports the spiral tube base and also provides an air conduit for air injection inside the tube. The frame is fixed to the spiral ribs on the top and bottom of the frame. End plates can be fixed to the frame by bridge pieces and pins. Sections of tubes can be connected end to end by bridge pieces and pins. The pins can be pipe pieces that can also provide air connections between the tube sections. One of the end plates can provide an inlet opening for an effluent inlet pipe.
