Abstract: A wastewater geothermal heat system is supplied with processed wastewater through a drip field in proximity to a thermal array part of a geothermal heat pump system. The wastewater treatment system portion provides a periodic source of treated wastewater. Several sensors and a control system regulate a pump that discharges wastewater from the treatment system and enters a drip field where it is released into the surrounding soil. The dampened soil provides an efficient vehicle to transfer heat into or out of a thermal array which is positioned adjacent to the drip field such that it is in contact with the soil that is dampened by the discharged wastewater.

Abstract: Some examples provide methods, systems, devices and/or apparatus related to reducing and/or restricting water from entering underground transportation system, and more Specifically, to reducing and/or restricting water from entering underground transportation systems via vents based on the weight of the water, while not restricting ventilation airflow when water is not present. Some example systems for restricting water flow in a surface vent may include a frame that receives water, a door pivotally coupled to the frame(where the door may pivot between a first position and a second position), and a reservoir pivotally coupled to the door. The reservoir may collect the received water and may cause the door to pivot between the first position and the second position based on weight of the collected water.

Abstract: The present invention provides an apparatus and method for recovering the core (108) of a subterranean sheathed electrical cable (106), while minimising the impact on the surrounding environment. The apparatus comprises a ram (102) operable to exert a pushing force on the core of a length of the cable, a plurality of linkages, each linkage being configured to be insertable into the cable along its length under the action of the ram to displace the core relative to an outer sheath of the cable, and a puller operable (104) to exert a pulling force on the core to thereby facilitate removal of the displaced core from the outer sheath by action of the pushing/pulling forces. The apparatus and method are found to be particularly suited to the recovery of high-tension copper core cables, while enabling any hydrocarbon (e.g. oil) impregnated inner sheathing to be controllably disposed of without hazard to the environment.

Abstract: Systems, devices, apparatus, and methods of locking and unlocking a door that is slidable by articulating wheels in tracks, over an entry port to a storm water structure. Locking the door can be accomplished by rotating bolts that are attached to cams. Rotating the bolts causes the cams to press the door against the tracks. Sealing strips can be compressed between door edges and the track to prevent water from passing around the door. A vacuum truck can remove water and debris from the vault/structure. Other versions allow doors to move downward to allow water to overflow the door. The door can slide upward so water can flow underneath. A door in door version has a secondary door slide up and down in tracks in a main door.

Abstract: A spool has a cylinder, a first flange coupled to a first end of the cylinder and a second flange coupled to a second end of the cylinder. A compressible material surrounds the cylinder and an optical fiber is wrapped around the compressible material. When tension is applied to the optical fiber the compressible material can be deformed to reduce the tension on the optical fiber. When submerged underwater the water pressure will not compress the compressible material.
