A smart root watering system is disclosed. The system includes a controller, configured to control the system using artificial neural networks. The system further comprises vertical tubes, inserted into the soil proximity to the roots of trees and configured to deliver water to the roots of trees. The vertical tubes include a motion sensor, configured to detect variation in water flow and wirelessly send data to the controller, thereby indicating faults of the vertical tubes to the user via a handheld electronic device. The vertical tube further includes a mechanical valve with a floater, configured to regulate input water to the system with respect to the soil absorption. The system further comprises a sensor device, configured to detect the humidity level and send to the controller. The controller is further configured to estimate the required volume of water and open an electric valve for supplying water to the roots of trees.

A weed barrier includes a rigid body defining a plurality of basins. The basins have bottoms with holes therethrough for planting garden plants. In a particular embodiment the bottom surface of the weed barrier includes a plurality of hose channels configured be positioned over a hose. Several example configurations of rigid weed barriers are disclosed.

A drip emitter is provided for delivering irrigation water from a supply tube to an emitter outlet at a reduced and relatively constant flow rate. Water enters the emitter through a first inlet and proceeds into a first chamber. When the water pressure is above a predetermined level, a one-directional valve opens to allow fluid flow past the first chamber, through a tortuous path flow channel, and through an emitter outlet. A second inlet is used to compensate for water pressure fluctuations in the supply tube to maintain output flow at a relatively constant rate. Water enters the second inlet and presses a flexible diaphragm toward a water metering surface to provide pressure-dependent control of the output flow. A copper member is mounted to the emitter over the emitter outlet to prevent plant root intrusion into the emitter outlet.

The invention relates to a system and method for containing and mitigating spills and leaks from pipelines. According to one embodiment, the system comprises a pipeline for transporting a liquid; a barrier layer comprising material impermeable to the liquid; a trench excavated with sufficient depth and width to accommodate at least the pipeline as well as the barrier layer; two berms; and backfill. The berms are substantially parallel and positioned on either side of the trench. The barrier layer is disposed to cover the trench and berms, reaching at least the ridgeline of the berms. The pipeline is disposed within the trench above the barrier layer. The backfill is placed on top of the pipeline and the barrier layer, and the backfill is graded to form a grade bridging the ridgelines of the berms.

A self-feeding watering device comprises a water storage unit, a regulating component and a long nozzle cover, and a water guide string extending out of the water storage unit. The regulating component is engaged to the water storage unit. The cover comprises a top cover for connecting with an external container and a long nozzle tube penetrating through the top cover and communicating with the top cover. The long nozzle tube further penetrates through the regulating component and extends towards a bottom of the water storage unit. The string is partially placed at the bottom of the water storage unit, and partially extends out of the water storage unit. The string allow water to penetrate into outside of the unit, and further guiding the water into the soil for automatic irrigation. The device has a compact structural body, can adjust a watering flow rate by a simplified means.
