Vertical drainage systems are drainage systems using pumped wells, either open dug wells or tube wells. Map of a well field for subsurface drainage with radial flow across concentrical cylinders representing the equipotentials. Both systems serve the same purposes, namely water table control and soil salinity control. Both systems can ...
Advanced Drainage Systems, Inc. (ADS) is a company that designs, manufactures and markets polypropylene and polyethylene pipes, plastic leach field chambers and systems, septic tanks and accessories, storm retention/detention and septic chambers, polyvinyl chloride drainage structures, fittings, and water filters and water separators.

Retention ponds such as this one in Dunfermline, Scotland, are considered components of a sustainable drainage system. Sustainable drainage systems (also known as SuDS, [1] SUDS, [2] [3] or sustainable urban drainage systems [4]) are a collection of water management practices that aim to align modern drainage systems with natural water processes and are part of a larger green infrastructure ...
Broadly equivalent terms used elsewhere include Sustainable drainage systems (SuDS) in the United Kingdom (where LID has a different meaning), water-sensitive urban design (WSUD) in Australia, natural drainage systems in Seattle, Washington, [3] "Environmental Site Design" as used by the Maryland Department of the Environment, [4] and "Onsite ...
In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...
Overland flow can be routed between sub-areas, between subcatchments, or between entry points of a drainage system. SWMM also contains a flexible set of hydraulic modeling capabilities used to route runoff and external inflows through the drainage system network of pipes, channels, storage/treatment units and diversion structures.
The type of system selected is dependent upon the chemistry of the acid mine drainage and the flow of the discharge, as well as relevant regulations. Passive treatment systems do not require power and are less expensive than active treatment systems. They also require less maintenance, which is an advantage in remote locations. [1]
A flow control structure is a device that alters the flow of water in a stream, drainage channel or pipe. As a group these are passive structures since they operate without intervention under different amounts of water flow and their impact changes based on the quantity of water available.
