US Patent:

6840710, Jan 11, 2005

Filed:

May 15, 2002

Appl. No.:

10/147184

Inventors:

Stanley R. Peters - Castle Rock CO, US
Randall R. Beeson - Arvada CO, US
Donald O. Summers - Lakewood CO, US

Assignee:

RAR Group, LLC - Lakewood CO

International Classification:

B65G 500

US Classification:

405 57, 405267, 405270

Abstract:

An underground reservoir for storing water in alluvial deposits utilizes slurry walls keyed to an aquiclude beneath the reservoir to form a substantially impermeable water seal. A variety of water extraction/recharge apparatus provides for rapid and complete filling and draining of the underground reservoir. Such apparatus includes a plurality of wells distributed about the underground reservoir and a series of perforated pipes buried at a predetermined depth within the underground reservoir. A method of mitigating water table fluctuations resulting from the construction of an underground utilizes perforated pipes buried outside of the reservoir to transfer excess water from an uphill land parcel to a downhill land parcel that would otherwise experience a water shortage after construction of the underground reservoir.

PS Systems, Inc. - Lakewood CO

International Classification:

B65G 5/00

US Classification:

405 53, 405 55

Abstract:

Natural soils and underlying bedrock typical of channel banks near a river and floodplain system are utilized to improve the economics and efficiency of constructing an underground porosity storage reservoir. A man-made barrier, typically a slurry wall, is keyed into these banks and forms a first portion of a closed boundary for the reservoir. The channel banks between the two ends of the slurry wall form a substantially impermeable natural barrier defining a second portion of the closed boundary for the reservoir, thereby reducing the construction costs on sites appropriate for such a design. Locating the bank-sided porosity storage reservoir over naturally occurring scour regions in the bedrock can greatly increase the storage capacity. By building an embankment and extending the slurry walls higher, an open water storage area can be created on top of the reservoir that is bounded by the elevated slurry wall and the channel bank.

RUSSELL J. SASAKURA - LITTLETON CO, US
DONALD O. SUMMERS - MORRISON CO, US

International Classification:

F28D 20/00

Abstract:

This disclosure describes systems and methods for the underground storage of heated or cooled fluid in order to preserve the temperature of the fluid. The systems described herein utilize one or more porosity storage reservoirs for heated or cooled fluid storage, in effect creating cold and or heat reservoirs in the subsurface. The reservoirs are hydrologically separated from the surrounding natural groundwater regime and, at least in part, thermally insulated from the natural environment by the walls creating the underground reservoirs. The walls may be actively or passively heated or cooled to provide better performance.
