20090297271 | Turf Playing Surface Aeration and Drainage System - A perforated pipe network beneath a playing surface. A blower connected to the pipe network drawing an air flow through the pipe network to create a vacuum. A drain pipe connecting to the pipe network. An air/water separator connected upstream of the blower for separating water from the air flow prior to entering the blower and channeling the water into the drain pipe for discharge. A flow control unit having a unit inlet connected to the drain pipe downstream of the air/water separator and a unit outlet discharging water to a drain outlet. The flow control unit blocking air flow through the unit inlet into the drain pipe when the blower is in the vacuum mode, and opening the unit inlet when a waterhead buildup at the unit inlet exceeds the vacuum level established by the blower to discharge water through the drain outlet. | 12-03-2009 |
20100143037 | Water/fluids surgie/backflow protection systems and management - This design addresses the problems of high tide/surges entering the discharge outlets of piping from pumping stations that discharge into a reservoir/body i.e., lake, river or waterway that is affected during storms, hurricanes or heavy rains driven by high tides and wind, that render pumping inefficient at least and inoperable at worst. This is a bypass system of piping into a manifold header that includes an inlet from the pump's discharge pipe, a discharge outlet and a second optional discharge—by pass outlet. It also includes optional automatic shut off valves in the piping scheme and variable speed drives on the pump motors. The by pass discharge outlet piping also includes an ancillary piping arrangement that allows portions of the discharge flow to be directed back into underground aquifers to replenish the diminishing water table level that contributes to subsidence. This system is subject to many possible modifications. | 06-10-2010 |
20140064852 | Distribution System and Method - A distribution system and method for simultaneously distributing and reclaiming a liquid with a single, multi-directional system pathway. The system pathway follows a circuitous path for both receiving liquid from and returning reclaimed liquid to a reservoir positioned beneath a ground surface. A distribution pathway, such as a pipe, may carry the liquid with pressure from the reservoir to a distribution outlet. A reclamation pathway, such as a perforated pipe, may encapsulate the distribution pathway, and capture runoff and excessive liquid through at least one aperture for returning the liquid back to the reservoir. In some embodiments, the system pathway may include one perforated pipe that forms a barrier between the distribution pathway and the reclamation pathway. A film may cover the perforations to allow for pressurizing the water. A system of pumps, valves, and a control apparatus help regulate the liquid. | 03-06-2014 |
20140193200 | MOISTURE CONTROL GRID - A moisture collection apparatus is provided to collect and store percolating ground water for increased water absorption by foliage growing above the moisture collection apparatus. In one embodiment, the moisture collection apparatus includes a first plurality of strands extending along a first direction, a second plurality of strands extending along a second direction and connected to at least one of the first plurality of strands, a plurality of channels extending along at least one of the first direction and the second direction, and a plurality of openings between adjacent strands of the first plurality of strands and adjacent strands of the second plurality of strands. In another embodiment, the first direction is substantially orthogonal to the second direction, such that the moisture collection apparatus forms a grid-like pattern of channels. | 07-10-2014 |
20150299972 | POND WATER DIVERSION APPARATUS FOR FLOOD CONTROL AND PREVENTION OF CASTOR INFESTATION - An apparatus for water level management in bodies of water is provided herein. Further, a method of controlling beaver infestation in bodies of water is also provided. | 10-22-2015 |
20160014980 | Subsurface Irrigation - A subsurface emitter includes a piston valve both preventing water from draining from the system, and blocking the entry of roots and soil into the emitter body. A nozzle is present at one or both ends of a vertical tube. A piston is held in a normally closed position by a spring in the absence of water pressure, covering ports in the nozzle. When sufficient water pressure in provided, the spring is compressed and the nozzle uncovers the port providing a subsurface spray of water. The spray of water is sufficient to clear mineral deposits which otherwise may accumulate and block the port. | 01-21-2016 |
