Underground Alluvial Water Storage Reservoir Containment Walls: In scarcity WATER is worth more than GOLD. Storing water is a good business practice in areas where water is scarce and in high demand. Using DeWind’s Underground Water Reservoir Containment Systems are the most cost-effective way to store large volumes of water. DeWind’s largest most powerful DEEP One-Pass Trencher can install deep in-situ mixed impermeable soil/ bentonite walls up to 125 below grade to form underground water storage reservoirs. The bottoms of these walls can be keyed into a confining layer creating a leak -free underground storage tank. This cost effective reservoir construction for large volume water storage can be used by cities and municipalities to conserve and store water during times of drought and high water use. Reservoirs installed in combination with DeWind’s Horizontal Water Supply Systems can be refilled quickly with nearby shallow water aquafers. Installation of these underground reservoirs are: Developed and installed in a very short time. Do not affect the surrounding water rights. Do not require an environmental impact study Maintains permanent dominion and control of the water Have no evaporation loss. Does not mix with local water sources. Storage capacity is not limited to local aggregate consumption Water will be always be available Details & Benefits: Depths:80′Below Grade COST EFFECTIVE: Speed:Developed and Installed in a very short time Results:No Evaporation Loss © 2012 Dewind.

Cement Footing Foundations and “Formless Wall” Installs: Imagine installing cement foundations without excavating or setting forms-with the DeWind One-Pass Trenchers, same day installs are a reality. DeWind’s One-Pass Trenchers cut a perfect 24” to 48” wide trench up to varying depths while pulling an open trench box in tow. The box remains full with wet mixed concrete as the trencher advances along the alignment of the proposed wall. While the concrete is still wet, cages and rebar can be inserted into the new-formed wall. Although this technology has a limited use for large simply designed projects, it is a consideration for some unusual applications like reinforcing dam stability, erosion control for beaches slopes and foundation stabilization. Because of the ability of the DeWind One-Pass Trencher, engineers can use this single pass equipment for a wide range of projects. Details & Benefits: Trench Depths:variable Trench Width:24″- 48″ wide Uses:Large and simply designed projects.
