  2. Stormwater detention vault - Wikipedia

    en.wikipedia.org/wiki/Stormwater_detention_vault

    Tunnels may be cheaper than basins, as they do not require pumps to move the water. [6] 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.

    en.wikipedia.org/wiki/Sanitary_sewer

    A lift station is a sewer sump that lifts accumulated sewage to a higher elevation. They may also be used to prime an inverted siphon used to cross underneath rivers or other obstructions. The pump may discharge to another gravity sewer or directly to a treatment plant. [6]

  4. Pumping station - Wikipedia

    en.wikipedia.org/wiki/Pumping_station

    A pumping station is an integral part of a pumped-storage hydroelectricity installation. Pumping stations are designed to move water or sewage from one location to another, overcoming gravitational challenges, and are essential for maintaining navigable canal levels, supplying water, and managing sewage and floodwaters. In canal systems ...

    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.

    The lift station is designed to convey wastewater to treatment facilities through a system of pipes and pump stations, which is treated according to federal and state standards.

  7. Gravity sewer - Wikipedia

    en.wikipedia.org/wiki/Gravity_sewer

    The capitalized cost of operation and maintenance of lift stations and emergency power supplies usually justifies considerable first cost for excavation or tunneling to build a gravity sewer. [3] Sewage treatment is most efficient at centralized locations; and pumping is often required to lift sewage from lower elevations to the sewage ...

  8. Sanitary manhole - Wikipedia

    en.wikipedia.org/wiki/Sanitary_manhole

    A main component of the base section is a channel that provides a smooth conduit for wastewater to flow from inlet pipe to outlet pipe. The channel is in a U shape formed by a "half pipe" as if a pipe is cut in half and left with the bottom half. The width of the channel should match the inside diameter of the inlet and outlet pipes.

  9. Sanitary sewer overflow - Wikipedia

    en.wikipedia.org/wiki/Sanitary_sewer_overflow

    Another mode of system failure can include power outages, which may disable lift station pumps and cause sewage overflow from the lift station wet well. Lift station mechanical or power failure causes approximately ten percent of United States SSOs. This type of discharge is uncommon from combined sewers, because the combined volume of sewage ...
