Facilities including pumps and equipment for pumping fluids from one place to another

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. 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, 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 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 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. 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 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 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 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 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 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 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; 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 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.

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 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 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 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.
