Water pumps: Applications

Water pumps are mechanical and electrical machines to pump water in and out of a site. In a mechanical water pump, water is pumped from the pipes submerged in a drain or a sewer. This water is pumped in by a mechanical engine of the water pump that creates a suction. The water then goes through the mechanical engine that consumes petrol or gas to run at its peak. The water from the engine is then released to a safe location via network of pipes or hoses. These pipes or hoses are connected with each other with a hose fitting. Electrical pumps on the other hand, are used as submersibles. The pump is plugged in an extension cord and lowered in to a space filled with water. The water goes through the pump and out of the network of hoses connected to the electrical pump. They are mainly used to water proof a construction site or stop flooding.

   Water pumps at construction sites are used for existing water features such as wetlands, streams, water sheds. flood plains etc. In a residential construction, the water pump is usually used to keep water away from the foundation of the building. A structure built in a center of a terrain with a slope is more likely to gather water at its foundation. This water then affects the load bearing capacity of the structure as the soil underneath the foundation retains more moisture than needed. This water is usually pumped out using an electrical pump away from the construction site on to sewer, drains, fields and open spaces. Water that gathers in the form of a swamp around a site usually creates mud and unsuitable conditions to move around or operate machinery. These machinery and equipment include Bull dozers, Forklift equipment (For Lumber), Cranes etc. Transporting materials like lumber, steel columns and roof trusses in and around the perimeter of a structure becomes a hazard. Not to mention the damage caused by water to the building materials lying around the perimeter of the structure. Water pumps may also be used along with heavy duty vacuum suction for water proofing structure interior. These vacuums may be used on laminated veneer lumber as well as small crawl spaces like an elevator under construction to avoid damage done using a snow shovel for example. Underlayment and plastic blankets may also be used to cover structure elements exposed to snow and rain. Waterproofing is also done before concrete pour over to avoid air bubbles from forming in concrete which lead to cracks and damage as a result of severe weather. Hence, water pumps on constructions sites are essential tools of trade.

   Water pumps may also be used to contain flooding. Whether tsunami, hurricane or a basement flood. Water pumps can be used to safely pump the water out of  the target locations. Usually water pumps for flood control are near sea or ocean shorelines. These pump facilities are the size of a factory. They use electricity to operate and keep the water away from land. Without electricity, these pumps can not function. For example, the one used during hurricane Katrina in New Orleans failed as the flood water filled the parts of the structure where pumps were located cutting electricity and making the pumps in operational. Water pumps to control basement flooding are a totally different story. Electric submersible water pumps may be used to pump out water in a basement flood. These pumps may run fully submerged in water up to several feet deep as long as the wiring of the pump can handle. Though basement floods are usually controlled using drain systems and gravel to soak rain and flood water around a perimeter of a structure, water pumps do come handy in extreme situations.

   In conclusion, water proofing construction sites and basement floods are done using water pumps. Though these pumps are mainly used for the applications above, they are also used for fire fighting and Irrigation. A structure with a handy mechanical water pump may be successful in fighting flammable fire to a certain extent. In a rural and isolated area where emergency response takes time to arrive, these pumps could be a life saver. Even small forest fires may be controlled using these pumps. They may also be connected to a fire hydrant to provide water in emergency. Water for field irrigation either for gardening or agriculture may be done using these water pumps. Extension hoses connected to these pumps may be spread across a field like a network. These pumps may act as sprinklers in places which otherwise would take hours to water. Further innovations in science and technology may prove beneficial to water pump design as well as economics related to its applications.
