A fire hydrant assembly for use with an irrigation riser stub may include a generally cylindrically-shaped main body having an open end and a closed end. The open end of the main body has an inside diameter that is sized to slidably receive an end portion of the irrigation riser stub. A seal disposed within the open end of the main body is sized to sealingly engage the irrigation riser stub. A nipple having a threaded end and a plain end is mounted within an opening provided in a side portion of the main body so that the threaded end may be threaded onto a fire hose assembly. An actuator shaft extends through a shaft opening defined by the closed end of the main body so that a head end of the actuator shaft is disposed outside the main body and so that a distal end of the actuator shaft is disposed within an interior cavity defined by the main body. A yoke mounted to the distal end of the actuator shaft is sized to operatively engage a valve stem associated with the irrigation riser stub.

Apparatus, systems and methods for irrigating lands are disclosed. In one example, an irrigation system is disclosed. The irrigation system includes a gate and a microcontroller unit (MCU). The gate is configured for adjusting a water flow for irrigating a piece of land. The MCU is configured for controlling the gate to adjust the water flow based on environmental information related to the piece of land.

A control gate adapted to be installed across a channel for liquids. The control gate includes a barrier member with a side member that has a circular arcuate section, the barrier member being pivotally mounted at or adjacent to the base of the channel; and a drive for raising and lowering the barrier member. The drive includes a cable, motor and first and second pulleys. The first pulley is coupled to the motor, the cable is secured to opposite first and second ends of the arcuate section, with the second pulley being adjacent to the arcuate section. The cable passes along the arcuate section from the one end to pass under the second pulley in contact therewith, is looped around the first pulley, above the second pulley, then passes under the second pulley and is secured to the second end of the arcuate section.

An arrangement for controlling and measuring flow. The arrangement includes a fluid control barrier and a flow-measuring apparatus upstream of the fluid control barrier. The fluid control barrier includes a pair of plates for opening and closing a pipe, and the plates are movable towards a center line of the pipe to open the pipe and produce a symmetrical flow profile for the flow-measuring apparatus.

A vegetated or non-vegetated buffer water retention system. The current invention can be utilized for both smaller scaled (e.g., residential or commercial) purposes or larger scaled (e.g., agricultural, municipal, industrial) purposes. In certain embodiments, the system generally includes a perforated drainage pipe and an elevated overflow controller apparatus (e.g., T-shaped member, arched overflow valve apparatus) in open communication with each other. These components allow the system to control the soil matrix water table. With additional valves, pumps, and water reservoirs, the system can control both the soil matrix water table and stored water reuse. The systems can be used not only to enhance plant root uptake and microbial utilization of nutrients and pollutants in water, but also to capture and reuse water inflows, thereby aiding in flooding abatement, water conservation and preventing soil erosion.
