A trenchless collector system is configured to intercept and direct surface and/or subsurface fluids to a designated reception location to control groundwater elevations. A target collection and drainage area is identified and a gravity drainage pipe is accessed or trenchlessly installed at the target collection and drainage area. The gravity drainage pipe can be accessed at one or more drawdown points. One end of a collection pipe can be connected to the gravity drainage pipe. Surface and subsurface water is hydrostatically drawn into the collection pipe from the target collection and drainage area through venting at the one end of the collection pipe connected to the gravity drainage pipe. The surface and subsurface water can be passively drained from the collection pipe into the gravity drainage pipe and onto the designated reception location.

Water management systems and methods of constructing water management systems comprising two-dimensional arrays of cells. Each cell has a base and a cell top module stacked on the base, the cell top module having a top flange and at least one top leg, a lower end of which engages the base. A base of one system has a bottom leg with an upper end cavity configured for a lateral clearance fit of a lower end portion of the top leg. The cavity holds at least one stacked spacer and is filled with a flowable substance after the top leg is inserted and positioned on the spacer. The flowable substance hardens to fully seat the lower end portion of the upper leg. Another system series of the cell top flanges being held together by tension cables extending therethrough.

Methods, apparatus, and systems involving high aspect ratio conduits are provided. These may involve a plurality of high aspect ratio leaching channels that may be spaced a predetermined distance apart from each other. The predetermined distance can facilitate backfilling of the volumes of adjacent high aspect ratio leaching channels. The backfill may be sand as well as other materials.

A channel drain for use in a fabricated surface having an exposed appearance. The channel drain includes a first body having a plurality of support surfaces, with each support surface extending from a respective body sidewall in spaced relation to a body lower wall. A plurality of inserts are insertable into the first body. Each insert includes an insert cavity sized and structured to receive a selected material having an appearance substantially identical to the exposed appearance of the fabricated surface. Each insert is supported by certain ones of the plurality of support surfaces when inserted into the first body and is sized and structured to define a gap between the pair of body sidewalls when inserted into the first body, with the gap allowing for fluid to flow therethrough toward the body lower wall.

A device and a method for treating soft soil foundations, the device comprises: a drainage plate (4), a water collection well (7), and a pressurizing drainage pipe (6), the pressurizing drainage pipe (6) is connected to the bottom of the drainage plate and the bottom of the water collection well through pipelines; a pressurizing module comprises: film (12), the film (12) is impermeable and covers the soft soil foundation; a pile-loading body (13), the pile-loading body (13) is arranged on the film; air compressor (1) has a pressurizing end with a space below the film to make a soil layer of the soft soil foundation below the film under an air pressure higher than the atmospheric pressure, so that the underground water discharge process can be started.

Stormwater management systems, methods, and apparatuses for containing and filtering runoff may be provided. In one implementation, a stormwater management system may include a stormwater chamber configured for placement underground; a flared end ramp at the inlet of the stormwater chamber that is configured to receive runoff containing sediment and to distribute the sediment across a width of the stormwater chamber; and a filtration fabric situated beneath the stormwater chamber, the filtration fabric being configured to capture sediment from the runoff in the stormwater chamber while the runoff flows out of the stormwater chamber.

Protection of upland areas adjacent to a variety of water body shorelines from flooding events by combining modified drainage culverts with and hidden by natural ecosystem flood attenuation environments.

Disclosed is a system and method usable for controlling multiple flows of water. The system may include a first sensor configured to sense a condition, a first drain tile, a first flow regulator configured to control a flow of water in the first drain tile, and a first transceiver configured to control the first flow regulator based on the sensed condition.

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.
