  2. Basement waterproofing - Wikipedia

    en.wikipedia.org/wiki/Basement_waterproofing

    A common system for draining water that has penetrated a basement involves creating a channel around the perimeter of the basement alongside the foundation footers. A French drain, PVC pipe, or other drainage system is installed in the newly made channel. The installed drain is covered with new cement. The drainage system collects any water ...

  3. Stormwater detention vault - Wikipedia

    en.wikipedia.org/wiki/Stormwater_detention_vault

    The outlet is generally a restricted-flow drain from the detention vessel, with a weir for containing detritus. [3] Detention vessels delay water's delivery downstream, and possibly creates a later water level peak post-rainfall. It is important to consider timing of water release and the types of reservoirs feeding a waterway. [7]

    Sustainable drainage system – Designed to reduce the potential impact of development; Tidal barrage – Dam-like structure; Tree box filter – Stormwater treatment system; Water-sensitive urban design – Integrated approach to urban water cycle; Wetland – Type of land area that is flooded or saturated with water

  5. Sustainable drainage system - Wikipedia

    en.wikipedia.org/wiki/Sustainable_drainage_system

    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 ...

  6. Drain-waste-vent system - Wikipedia

    en.wikipedia.org/wiki/Drain-waste-vent_system

    A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.

  7. French drain - Wikipedia

    en.wikipedia.org/wiki/French_drain

    A diagram of a traditional French drain. A French drain [1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain [1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area.

  8. Drainage density - Wikipedia

    en.wikipedia.org/wiki/Drainage_density

    Drainage density relates to the storage and runoff terms. Drainage density relates to the efficiency by which water is carried over the landscape. Water is carried through channels much faster than over hillslopes, as saturated overland flow is slower due to being thinned out and obstructed by vegetation or pores in the ground. [7]

  9. Watertable control - Wikipedia

    en.wikipedia.org/wiki/Watertable_control

    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 ...
