A stormwater management system adapted for retaining or detaining stormwater. The underground system comprises a plurality of cells arranged in a generally honeycomb configuration. Each of the plurality of cells is generally hexagonal in cross-section and has an internal region. The plurality of cells are in fluid communication with one another to allow stormwater to flow from the internal region of one of the plurality of cells to the internal region of another of the plurality of cells.

Individual hexagonal shaped modules used in an assembly for underground storage of storm water and other fluid storage needs. Modules are assembled into a resultant honeycomb shape for maximized structural strength and material use efficiency. Adjacent modules are in direct fluid communications with one another via openings or windows in module side walls. Assemblies include various top and side pieces along with access ports for entry into said assembly.

A culvert pipe inlet arrangement includes a pan member and an inlet that is configured to be disposed within a culvert pipe is disclosed.

A webless corrugated dual wall foundation drain which is constructed as a hollow rectangular tubular member with an inner corrugated wall formed of HDPE and an integral outer smooth wall formed of the same material. The outer smooth wall of the foundation drain is attached to and integrally formed with the corrugations of the inner corrugated wall through a coextrusion process, thereby significantly enhancing the vertical beam stiffness of the foundation drain and eliminating the need for an internal supporting web.

A water-salt regulation system for coastal regions, including an irrigation canal, a plurality of drainage channels, and a shaft. The irrigation canal is arranged on a surface farmland. The drainage channels are provided inside a soil. The irrigation canal and the drainage channels are inclined from inland to sea. The shaft is provided with a water port at which a sluice gate is provided. An inner peripheral wall of the water drainage channel is provided with a plurality of filter mesh frames with an accommodating cavity. A filter filling material is provided inside the accommodating cavity. The shaft is provided with a salinity sensor. The shaft has a first state with the sluice gate on the drainage channel closed and a second state with the sluice gate on the drainage channel opened. A water-salt regulation is also provided.

A wet material having at least a liquid portion is dewatered by providing one or more wicking members of wicking material arranged to transfer moisture passively by wicking therethrough from a contacting portion in contact with the wet material to an evaporating portion where the transferred liquid portion is arranged to be evaporated. In some embodiments conductive elements are included in the wicking member to assist in distributing heat across the wicking member which enhances the evaporation of moisture transferred therethrough from the wet material. In yet further embodiments, a condenser member is provided in proximity to the evaporating portion of the wicking member so as to be arranged to condense and collect at least some of the liquid portion evaporated from the wicking member.

An arch-shaped corrugated chamber having corrugation peaks and valleys, with reinforcing ribs provided on the corrugation peaks. The ribs extend upwardly from a chamber base to a rib upper end, and have an arch-shaped cross-section with an outer surface extending outwardly from a corrugation peak and a fin extending inwardly from the corrugation peak, and optionally, a rib line provided on the rib outer surface centered on the rib arch-shaped cross-section. A channel formed by the inner surface of the rib is sized to receive a corresponding rib of a second chamber so that multiple similar chambers with ribs may be stacked together.

Described herein is a method of controlling soil moisture, water accumulation and fertilizer distribution in land. Elevation location data for land areas are extracted from two or more pixels of a topographic image including topographic data. Each pixel represents a land area. Wetness indices for the land areas are determined from the elevation and location data, based on the slope between two or more defined areas of land and an upslope contributing area per unit contour length. At risk defined areas of land, e.g., those at risk of accumulating water are identified based on wetness indices. Water is transported from the at risk defined areas of land to another location. The transporting of water reduces the risk of accumulating water in the at risk defined areas of land and improves crop growth potential in those areas.
