Pumping stations , also called pumphouses , are public utility buildings containing pumps and equipment for pumping fluids from one place to another. They are critical in a variety of infrastructure systems, such as water supply, drainage of low-lying land , canals and removal of sewage to processing sites. A pumping station is an integral part of a pumped-storage hydroelectricity installation.

67-445: 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, pumping stations help replenish water lost through lock usage and leakage, ensuring navigability. Similarly, in land drainage, stations pump water to prevent flooding in areas below sea level,

134-423: A sewer force main if the sewage is transported some significant distance. The pumping station may be called a lift station if the pump merely discharges into a nearby gravity manhole. From here the cycle starts all over again until the sewage reaches its point of destination—usually a treatment plant. By this method, pumping stations are used to move waste to higher elevations. In the case of high sewage flows into

201-403: A well into a reservoir Used to pump drinking water from a reservoir into a water supply system. Navigable A body of water , such as a river , canal or lake , is navigable if it is deep, wide and calm enough for a water vessel (e.g. boats) to pass safely. Navigability is also referred to in the broader context of a body of water having sufficient under keel clearance for

268-401: A chain off of the duckfoot and up the two guide rails to the maintenance (normally ground) level. Reinstalling the pumps simply reverses this process with the pump being remounted on the guide rails and lowered onto the duckfoot where the weight of the pump reseals it. As the motors are sealed and weather is not a concern, no above ground structures are required, excepting a small kiosk to contain

335-598: A concept pioneered during the Victorian era in places like The Fens in the UK. The introduction of "package pumping stations" has modernized drainage systems, allowing a compact, efficient solution for areas where gravity drainage is impractical. Water pumping stations are differentiated by their applications, such as sourcing from wells, raw water pumping, and high service pumping, each designed to meet specific demand projections and customer needs. Wastewater pumping stations, on

402-488: A direct transit of Mud Pond by canoe , within a tract of private property surrounded by public land within the Adirondack Park . In New York State, waterways that are 'navigable-in-fact' are considered public highways , meaning that they are subject to an easement for public travel, even if they are on private land. Brown argued that because he recreationally 'navigated' the waterway through private property, it

469-459: A dry well or pump house and usually consist only of a wet well. In this configuration, submersible sewage pumps with closely coupled electric motor are mounted within the wet well itself, submerged within the sewage. Submersible pumps are mounted on two vertical guide rails and seal onto a permanently fixed "duckfoot", which forms both a mount and also a vertical bend for the discharge pipe. For maintenance or replacement, submersible pumps are raised by

536-437: A high-level alarm indication, in the event of pump failure; and possibly a guide-rail/auto-coupling/pedestal system, to permit easy removal of pumps for maintenance. Traditional site constructed systems have the valve vault components installed in a separate structure. Having two structural components can lead to potentially serious site problems such as uneven settling between components which results in stress on, and failure of

603-552: A landowner can alter the drainage from their parcel. Drainage options for the construction industry include: The surface opening of channel drainage usually comes in the form of gratings (polymer, plastic, steel or iron) or a single slot (slot drain) that run along the ground surface (typically manufactured from steel or iron). Earth retaining structures such as retaining walls also need to have groundwater drainage considered during their construction. Typical retaining walls are constructed of impermeable material, which can block

670-403: A large open passage so as to avoid clogging with debris or winding stringy debris onto the impeller. A four pole or six pole AC induction motor normally drives the pump. Rather than provide large open passages, some pumps, typically smaller sewage pumps, also macerate any solids within the sewage breaking them down into smaller parts which can more easily pass through the impeller. The interior of

737-412: A pilot program called Street Edge Alternatives Project. The project focuses on designing a system "to provide drainage that more closely mimics the natural landscape prior to development than traditional piped systems". The streets are characterized by ditches along the side of the roadway, with plantings designed throughout the area. An emphasis on non-curbed sidewalks allows water to flow more freely into

804-457: A sewage pump station is a very dangerous place. Poisonous gases, such as methane and hydrogen sulfide , can accumulate in the wet well; an ill-equipped person entering the well would be overcome by fumes very quickly. Any entry into the wet well requires the correct confined space entry method for a hazardous environment. To minimize the need for entry, the facility is normally designed to allow pumps and other equipment to be removed from outside

871-437: A small river may be navigable by smaller craft such as a motorboat or a kayak , but unnavigable by a larger freighter or cruise ship . Shallow rivers may be made navigable by the installation of locks that regulate flow and increase upstream water level , or by dredging that deepens parts of the stream bed . Inland Water Transport ( IWT ) Systems have been used for centuries in countries including India, China, Egypt,

938-511: A specific pump controller. RTUs are very helpful in remote monitoring of each pumping station from a centralized control room with SCADA (Supervisory Control & Data Acquisition) systems. This setup can be helpful in monitoring pump faults, levels, and other alarms and parameters, making it more efficient. A pumped-storage scheme is a type of power station for storing and producing electricity to supply high peak demands by moving water between reservoirs at different elevations. Typically, water

1005-466: A vessel. Such a navigable water is called a waterway , and is preferably with few obstructions against direct traverse that need avoiding, such as rocks , reefs or trees . Bridges built over waterways must have sufficient clearance . High flow speed may make a channel unnavigable due to risk of ship collisions . Waters may be unnavigable because of ice , particularly in winter or high- latitude regions. Navigability also depends on context:

1072-551: A water-body is presumed non-navigable with the burden of proof on the party claiming it is navigable. The U.S. Forest Service considers a waterbody not navigable until is adjudicated otherwise. see Whitewater v. Tidwell 770 F. 3d 1108 (2014). Therefore, and public rights associated with navigability cannot be presumed to exist without a finding of navigability. 'Navigability' is a legal term of art , which can lead to considerable confusion. In 2009, journalist Phil Brown of Adirondack Explorer defied private property postings to make

1139-516: Is a list of those described in this encyclopedia. In the UK, during the Victorian Era , there was a fashion for public buildings to feature highly ornate architecture . Consequently, a considerable number of former pumping stations have been listed and preserved. The majority were originally steam-powered, and where the steam engines are still in situ , many of the sites have since re-opened as museum attractions. Used to pump water from

1206-407: Is available, back pumping systems may be employed. Water is extracted from the canal below the lowest lock of a flight and is pumped back to the top of the flight, ready for the next boat to pass through. Such installations are usually small. When low-lying areas of land are drained, the general method is to dig drainage ditches . However, if the area is below sea level then it is necessary to pump

1273-479: Is built into the system so that in the event that any one pump is out of service, the remaining pump or pumps will handle the designed flow. The storage volume of the wet well between the "pump on" and "pump off" settings is designed to minimize pump starts and stops, but is not so long a retention time as to allow the sewage in the wet well to go septic . Sewage pumps are almost always end-suction centrifugal pumps with open impellers and are specially designed with

1340-409: Is channeled from a high-level reservoir to a low-level reservoir, through turbine generators that generate electricity. This is done when the station is required to generate power. During low-demand periods, such as overnight, the generators are reversed to become pumps that move the water back up to the top reservoir. There are countless thousands of pumping stations throughout the world. The following

1407-431: Is fed from underground gravity pipelines (pipes that are sloped so that a liquid can flow in one direction under gravity). Sewage is fed into and stored in a pit, commonly known as a wet well . The well is equipped with electrical instrumentation to detect the level of sewage present. When the sewage level rises to a predetermined point, a pump will be started to lift the sewage upward through a pressurized pipe system called

1474-598: Is moved by this mode of transport. Waterways provide enormous advantages as a mode of transport compared to land and air modes of transports. Drainage Drainage is the natural or artificial removal of a surface's water and sub-surface water from an area with excess water. The internal drainage of most agricultural soils can prevent severe waterlogging (anaerobic conditions that harm root growth), but many soils need artificial drainage to improve production or to manage water supplies. The Indus Valley Civilization had sewerage and drainage systems. All houses in

1541-451: Is not possible. A package pumping station is an integrated system, built in a housing manufactured from strong, impact-resistant materials such as precast concrete , polyethylene , or glass-reinforced plastic . The unit is supplied with internal pipework fitted, pre-assembled ready for installation into the ground, after which the submersible pumps and control equipment are fitted. Features may include controls for fully automatic operation;

1608-505: Is not sufficient to prove that a waterway is a public highway in New York State. The US Supreme Court had also found that use of modern water craft insufficient evidence to support a finding of navigability In India there are currently three National Waterways totaling a distance of 2921 km. They are: It is estimated that the total navigable length of inland waterways is 14500 km. A total of 16 million tonnes of freight

1675-599: Is then folded over the top of the stone and the trench is then covered by soil. Groundwater seeps through the geotextile and flows through the stone to an outfell. In high groundwater conditions a perforated plastic ( PVC or PE ) pipe is laid along the base of the drain to increase the volume of water transported in the drain. Alternatively, a prefabricated plastic drainage system made of HDPE , often incorporating geotextile, coco fiber or rag filters can be considered. The use of these materials has become increasingly more common due to their ease of use, since they eliminate

1742-634: The Claverton and Crofton Pumping Stations , are preserved as museum attractions. Examples such as land drainage in the Netherlands water supply in Hong Kong and agricultural drainage in Iraq, underscore the vital role these facilities play in supporting modern infrastructure, environmental management, and energy storage. In countries with canal systems, pumping stations are also frequent. Because of

1809-531: The Netherlands . The area between Amsterdam , Haarlem and Leiden was, in prehistoric times, swampland and small lakes. Turf cutting ( peat mining ), subsidence and shoreline erosion gradually caused the formation of one large lake, the Haarlemmermeer , or lake of Haarlem. The invention of wind-powered pumping engines in the 15th century permitted some of the marginal land drainage. Still,

1876-406: The flatwoods citrus -growing region of Florida , United States. After periods of high rainfall, drainage pumps are employed to prevent damage to the citrus groves from overly wet soils. Rice production requires complete water control, as fields must be flooded or drained at different stages of the crop cycle. The Netherlands has also led the way in this type of drainage by draining lowlands along

1943-523: The Clean Water Act. Therefore, the Clean Water Act establishes Federal jurisdiction beyond "navigable waters" extending a more limited federal jurisdiction under the Act over private property which may at times be submerged by waters. Because jurisdiction under the Clean Water Act extends beyond public property, the broader definitions of "traditional navigable" and "significant nexus" used to establish

2010-715: The Mud Pond rapids." However, New York's highest court, the New York Court of Appeals overturned the lower court decisions, and sent the case back to the trial court for consideration of "the Waterway's historical and prospective commercial utility, the Waterway's historical accessibility to the public, the relative ease of passage by canoe, the volume of historical travel, and the volume of prospective commercial and recreational use." The decision by New York's highest court established that recreational 'navigability' alone

2077-603: The Netherlands, the United States, Germany, and Bangladesh. In the Netherlands, IWT handles 46% of the nation's inland freight ; 32% in Bangladesh, 14% in the United States, and 9% in China. What constitutes "navigable" waters can not be separated from the context in which the question is asked. Numerous federal agencies define jurisdiction based on navigable waters, including admiralty jurisdiction, pollution control, to

2144-493: The U.S. This statute also requires a permit from the U.S. Army Corps of Engineers for any construction in or over any navigable water, or the excavation or discharge of material into such water, or the accomplishment of any other work affecting the course, location, condition, or capacity of such waters. However, the ACOE recognizes that only the judiciary can make a definitive ruling as to which are navigable waters.33 CFR 329 For

2211-585: The accumulation of sedimentary mud that created the land initially. Elsewhere, pumping stations are used to remove water that has found its way into low-lying areas as a result of leakage or flooding (in New Orleans , for example). In more recent times, a "package pumping station" provides an efficient and economic way of installing a drainage system. They are suitable for mechanical building services collection and pumping of liquids like surface water, wastewater or sewage from areas where drainage by gravity

2278-412: The areas of permeable surface on the side of the streets. Because of the plantings, the run off water from the urban area does not all directly go into the ground, but can also be absorbed into the surrounding environment. Monitoring conducted by Seattle Public Utilities reports a 99 percent reduction of storm water leaving the drainage project. Drainage has undergone a large-scale environmental review in

2345-428: The construction process, they set out all the necessary levels for roads , street gutters , drainage, culverts and sewers involved in construction operations. Civil engineers and construction managers work alongside architects and supervisors, planners, quantity surveyors , and the general workforce, as well as subcontractors. Typically, most jurisdictions have some body of drainage law to govern to what degree

2412-449: The demand or projected demand is reasonably defined, and is dependent on a combination of customer needs and fire flow requirements. Average annual per-capita water consumption, peak hour, and maximum daily can vary greatly due to factors such as climate, income levels, population, and the proportions of residential, commercial, and industrial users. Pumping stations in sewage collection systems are normally designed to handle raw sewage that

2479-406: The drain. Geotextiles are synthetic textile fabrics specially manufactured for civil and environmental engineering applications. Geotextiles are designed to retain fine soil particles while allowing water to pass through. In a typical drainage system, they would be laid along a trench which would then be filled with coarse granular material : gravel , sea shells , stone or rock . The geotextile

2546-402: The drainage system. Drainage in planters refers to the implementation of effective drainage systems specifically designed for plant containers or pots. Proper drainage is crucial in planters to prevent waterlogging and promote healthy plant growth. Planter Drainage involves the incorporation of drainage holes, drainage layers, or specialized drainage systems to ensure excess water can escape from

2613-467: The ebb and flow of the tide, and those inland waters that are presently used, or have been used in the past, or may be susceptible for use to transport interstate or foreign commerce while the waterway is in its ordinary condition at the time of statehood. Section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. 403), approved 3 March 1899, prohibits the unauthorized obstruction of a navigable water of

2680-458: The efficiency and monitoring capabilities of pumping stations, essential for modern systems. Pumped-storage schemes represent a critical use of pumping stations, providing a method for energy storage and generation by moving water between reservoirs at different elevations, highlighting the versatility and importance of pumping stations across sectors. Some pumping stations have been recognized for their architectural and historical significance, e.g.

2747-417: The electrical switchgear and control systems. Due to the much reduced health and safety concerns, and smaller footprint and visibility, submersible pump sewage pumping stations have almost completely superseded traditional sewage pumping stations. Further, a refit of a traditional pumping station usually involves converting it into a modern pumping station by installing submersibles in the wet well, demolishing

2814-399: The final drainage of the lake had to await the design of large steam-powered pumps and agreements between regional authorities. The lake was eliminated between 1849 and 1852, creating thousands of km of new land. Coastal plains and river deltas may have seasonally or permanently high water tables and must have drainage improvements if they are to be used for agriculture. An example is

2881-644: The flow from non-navigable tributaries in order to protect commerce downstream, [ US v. Rio Grande Irrigation , 174 U.S. 690, 708 (1899)], [ Oklahoma v. Atkinson , 313 US 508, 525]. Also, the Clean Water Act has introduced the terms "traditional navigable waters," and "waters of the United States" to define the scope of Federal jurisdiction under the Clean Water Act. Here, "Waters of the United States" include not only navigable waters, but also tributaries of navigable waters and nearby wetlands with "a significant nexus to navigable waters"; both are covered under

2948-465: The licensing of dams, and even property boundaries. The numerous definitions and jurisdictional statutes have created an array of case law specific to which context the question of navigability arises. Some of the most commonly discussed definitions are listed here. Navigable waters, as defined by the US Army Corps of Engineers as codified under 33 CFR 329 , are those waters that are subject to

3015-420: The major cities of Harappa and Mohenjo-daro had access to water and drainage facilities. Waste water was directed to covered gravity sewers , which lined the major streets. The invention of hollow-pipe drainage is credited to Sir Hugh Dalrymple, who died in 1753. New storm water drainage systems incorporate geotextile filters that retain and prevent fine grains of soil from passing into and clogging

3082-426: The navigable water was conveyed to the state as part of the transportation network in order to facilitate commerce. Most states retained title to these navigable rivers in trust for the public. Some states divested themselves of title to the land below navigable rivers, but a federal navigable servitude remains if the river is a navigable waterway. Title to the lands submerged by smaller streams are considered part of

3149-414: The need for further pipework systems to be installed in parallel to the drainage, reducing the environmental impact of production as well as improving water collection. Stainless steel , concrete channel, PVC and HDPE are all materials available for slot drainage which have become industry standards on construction projects. The civil engineer is responsible for drainage in construction projects. During

3216-461: The need for transporting and laying stone drainage aggregate, which is invariably more expensive than a synthetic drain and concrete liners. Over the past 30 years, geotextile, PVC filters, and HDPE filters have become the most commonly used soil filter media. They are cheap to produce and easy to lay, with factory controlled properties that ensure long term filtration performance even in fine silty soil conditions. Seattle's Public Utilities created

3283-412: The other hand, are engineered to handle sewage, with designs that ensure reliability and safety, minimizing environmental impacts from overflows. Innovations in pump technology and station design have led to the development of submersible pump stations, which are more compact and safer, effectively reducing the footprint and visibility of sewage management infrastructure. Electronic controllers have enhanced

3350-564: The path of groundwater. When groundwater flow is obstructed, hydrostatic water pressure buildups against the wall and may cause significant damage. If the water pressure is not drained appropriately, retaining walls can bow, move, and fracture, causing seams to separate. The water pressure can also erode soil particles, leading to voids behind the wall and sinkholes in the above soil. Traditional retaining wall drainage systems can include French drains , drain pipes or weep holes . To prevent soil erosion, geotextile filter fabrics are installed with

3417-570: The pipes and connections between components. The development of a packaged pump station system combined all components into a single housing which not only eliminates uneven settling issues, but pre-plumbing and outfitting each unit prior to installation can reduce the cost and time involved with civil work and site labor. Water pumping stations are differentiated from wastewater pumping stations in that they do not have to be sized to account for high peak flow rates. They have five general categories: Water pumping stations are constructed in areas in which

3484-762: The planter. This helps to prevent root rot , water accumulation, and other issues that can negatively impact plant health. By providing adequate drainage in planters, it supports optimal plant growth and contributes to the overall success of gardening or landscaping projects. Drainage options for the planter include: Wetland soils may need drainage to be used for agriculture . In the northern United States and Europe, glaciation created numerous small lakes , which gradually filled with humus to make marshes . Some of these were drained using open ditches and trenches to make mucklands , which are primarily used for high-value crops such as vegetables . The world's largest project of this type has been in process for centuries in

3551-657: The property through which the water flows and there is no 'public right' to enter upon private property based on the mere presence of water. The scope of the Federal Energy Regulatory Commission (FERC) authority was granted under the Federal Power Act, 1941 (16 U.S.C 791). Such authority is based on congressional authority to regulate commerce; it is not based exclusively on title to the riverbed [16 U.S.C. 796(8)] or even navigability. Therefore, FERC's permitting authority extends to

3618-479: The pump house and retiring the dry well by either stripping it, or knocking down the internal partition and merging it with the wet well. Pump manufacturers have always designed and manufactured electronic devices to control and supervise pumping stations. Today it is also very common to use a programmable logic controller (PLC) or Remote Terminal Unit (RTU) for such work, but the experience needed to solve certain particular problems, makes an easy choice to look for

3685-406: The purposes of transferring property title into public property, the definition of a Navigable waterways closely follows 33 CFR 329. For the purpose of establishing which river is public and therefore state-owned, what is navigable is a constitutional question defined by Federal case law. (See PPL Montana v Montana (2012).) If a river was considered navigable at the time of statehood, the land below

3752-492: The recent past in the United Kingdom. Sustainable urban drainage systems (SUDS) are designed to encourage contractors to install drainage system that more closely mimic the natural flow of water in nature. Since 2010 local and neighbourhood planning in the UK is required by law to factor SUDS into any development projects that they are responsible for. Slot drainage is a channel drainage system designed to eliminate

3819-410: The roots eliminates air movement through the soil. Other soils may have an impervious layer of mineralized soil, called a hardpan , or relatively impervious rock layers may underlie shallow soils. Drainage is especially important in tree fruit production. Soils that are otherwise excellent may be waterlogged for a week of the year, which is sufficient to kill fruit trees and cost the productivity of

3886-479: The scope of authority under the Act are still ambiguously defined and therefore open to judicial interpretation as indicated in two U.S. Supreme Court decisions: Carabell v. United States and Rapanos v. United States . However, because authority under the Act is limited to protecting only navigable waters, jurisdiction over these smaller creeks is not absolute and may require just compensation to property owners when invoked to protect downstream waters. Finally,

3953-418: The sewage in the wet well, dry wells are underground, confined spaces and require appropriate precautions for entry. Further, any failure or leakage of the pumps or pipework can discharge sewage directly into the dry well with complete flooding not an uncommon occurrence. As a result, the electric motors are normally mounted above the overflow, top water level of the wet well, usually above ground level, and drive

4020-403: The sewage pumps through an extended vertical shaft. To protect the above ground motors from weather, small pump houses are normally built, which also incorporate the electrical switchgear and control electronics. These are the visible parts of a traditional sewage pumping station although they are typically smaller than the underground wet and dry wells. More modern pumping stations do not require

4087-404: The shore and pushing back the sea until the original nation has been greatly enlarged. In moist climates, soils may be adequate for cropping with the exception that they become waterlogged for brief periods each year, from snow melt or from heavy rains . Soils that are predominantly clay will pass water very slowly downward. Meanwhile, plant roots suffocate because the excessive water around

4154-557: The upper parts of the canal, but if no suitable source is available, a pumping station can be used to maintain the water level. An example of a canal pumping station is the Claverton Pumping Station on the Kennet and Avon Canal in southern England, United Kingdom. This pumps water from the nearby River Avon to the canal using pumps driven by a waterwheel which is powered by the river. Where no external water supply

4221-412: The water upwards into water channels that finally drain into the sea. The Victorians understood this concept, and in the United Kingdom they built pumping stations with water pumps , powered by steam engines to accomplish this task. In Lincolnshire, large areas of wetland at sea level, called The Fens , were turned into rich arable farmland by this method. The land is full of nutrients because of

4288-431: The way the system of canal locks work, water is lost from the upper part of a canal each time a vessel passes through. Also, most lock gates are not watertight, so some water leaks from the higher levels of the canal to those lower down. The water has to be replaced or eventually the upper levels of the canal would not hold enough water to be navigable. Canals are usually fed by diverting water from streams and rivers into

4355-438: The well (for example during peak flow periods and wet weather) additional pumps will be used. If this is insufficient, or in the case of failure of the pumping station, a backup in the sewer system can occur, leading to a sanitary sewer overflow —the discharge of raw sewage into the environment. Sewage pumping stations are typically designed so that one pump or one set of pumps will handle normal peak flow conditions. Redundancy

4422-404: The wet well. Traditional sewage pumping stations incorporate both a wet well and a "dry well". Often these are the same structure separated by an internal divide. In this configuration pumps are installed below ground level on the base of the dry well so that their inlets are below water level on pump start, priming the pump and also maximising the available NPSH . Although nominally isolated from
