A catchwater drain is a land drain, a ditch cut across the fall of the land, typically just above the level of low-lying, level ground such as The Fens of eastern England, where some land, tens of kilometres from the sea is at about sea level. Its purpose is to gather water draining from the higher, sloping ground before it reaches the flat ...
Catchwater drains may take the form of concrete canals, such as in Hong Kong, where there are many.Alternatively, they may take the form of a large concrete sheet, smothering a hill, and preventing rainfall from entering the rock strata, with a smaller channeling system for transport of the water to the storage tank - this latter system is in operation in Gibraltar.
The top layer of soil also allows the mound to be planted with grass or non-woody plants to control erosion The primary waste liquids cleaning and purification actions in a drain field are performed by a biofilm in the loose fill surrounding the perforated drain tile. If the soil permeability is too low, the liquid is not absorbed fast enough.
A ditch can be used for drainage, to drain water from low-lying areas, alongside roadways or fields, or to channel water from a more distant source for plant irrigation. Ditches are commonly seen around farmland , especially in areas that have required drainage, such as The Fens in eastern England and much of the Netherlands .
Stormwater harvesting or stormwater reuse is the collection, accumulation, treatment or purification, and storage of stormwater for its eventual reuse. While rainwater harvesting collects precipitation primarily from rooftops, stormwater harvesting deals with collection of runoff from creeks, gullies, ephemeral streams and underground conveyance.

Storm water is typically channeled to a retention basin through a system of street and/or parking lot storm drains, and a network of drain channels or underground pipes.. The basins are designed to allow relatively large flows of water to enter, but discharges to receiving waters are limited by outlet structures that function only during very large storm eve
