Mound systems are an alternative to the traditional rural septic system drain field. They are used in areas where septic systems are prone to failure from extremely permeable or impermeable soils, soil with the shallow cover over porous bedrock, and terrain that features a high water table.
Field drainage systems are differentiated in surface and subsurface field drainage systems. Sometimes (e.g., in irrigated, submerged rice fields), a form of temporary drainage is required whereby the drainage system is allowed to function only on certain occasions (e.g., during the harvest period). If allowed to function continuously, excessive ...
Hardpan can be a problem in farming and gardening by impeding drainage of water and restricting the growth of plant roots.In these situations, the hardpan can be broken up by either mechanical means such as digging or plowing, [3] or through the use of soil amendments.
Example research projects are to examine the biogeochemistry and microbial ecology of septic drain field soils used to treat domestic wastewater, the role of anecic earthworms in controlling the movement of water and nitrogen cycle in agricultural soils, and the assessment of soil quality in turf production.

Although one well may be sufficient to solve groundwater and soil salinity problems in a few hectares, one usually needs a number of wells, because the problems may be widely spread. The wells may be arranged in a triangular, square or rectangular pattern. The design of the well field concerns depth, capacity, discharge, and spacing of the ...
Tile drainage is a form of agricultural drainage system that removes excess sub-surface water from fields to allow sufficient air space within the soil, proper cultivation, and access by heavy machinery to tend and harvest crops.

Cross Sectional Diagram of a Two Stage Drainage Ditch . A drainage ditch is a depression in the land created to channel water.Drainage ditches are typically formed around low-lying areas, roadsides or fields proximate to a water body or created to channel water from a more distant water source for the purpose of plant irrigation.
