The drain system is simple in form: It's made up of trenches filled with gravel or rock that contain a perforated pipe that reroutes water away from problem areas. "The drain operates by allowing ...
Over-irrigation can cause deep drainage from rising water tables that can lead to problems of irrigation salinity requiring watertable control by some form of subsurface land drainage. However, if the soil is under-irrigated, it gives poor soil salinity control , which leads to increased soil salinity with the consequent buildup of toxic salts ...

Drainage law is a specific area of water law related to drainage of surface water on real property. It is particularly important in areas where freshwater is scarce, flooding is common, or water is in high demand for agricultural or commercial purposes.
Point drainage, which intercepts water at gullies (points). Gullies connect to drainage pipes beneath the ground surface, so deep excavation is required to facilitate this system. Support for deep trenches is required in the shape of planking, strutting or shoring. Channel drainage, which intercepts water along the entire run of the channel.
Agricultural land drainage has agricultural, environmental, hydrological, engineering, economical, social and socio-political aspects (Figure 1). All these aspects can be subject of drainage research. The aim (objective, target) of agricultural land drainage is the optimized agricultural production related to: reclamation of agricultural land
Infiltration will occur where local groundwater elevation is higher than the sewer pipe. Gravel bedding materials in sewer pipe trenches act as a French drain. Groundwater flows parallel to the sewer until it reaches the area of damaged pipe. In areas of low groundwater, sewage may exfiltrate into groundwater from a leaking sewer. [6]
Irrigation is the artificial exploitation and distribution of water at project level aiming at application of water at field level to agricultural crops [1] in dry areas or in periods of scarce rainfall to assure or improve crop production.
