The field of water hauling is unfamiliar to many people, but those employed in this industry carry out some very important functions. Water hauling trucks are sometimes dispatched to provide backup in emergency situations, such as a fire that threatens to spread out of control. They are also hired for non-emergency purposes, like filling swimming pools. Sometimes they are called upon to pump water out of holes, pits, and coal mines. In any event, if you're new to this field, you should be familiar with certain terms commonly used.
Potable water - More commonly known as drinking water, this is the proper term for water that is safe for human beings to drink. Potable water is usually transported in tanks especially designed for this purpose. Some water hauling services also deliver bottled potable water to businesses and residences.
Dust control - Preventing the spread of microscopic dust particles at a particular site. Because dust particles can pose a health hazard, water hauling trucks are often hired to spray down roads and construction sites, a method intended to minimize air pollution.
DEP - The abbreviation for the Department of Environmental Protection, they have the ability to certify potable water haulers.
Bulk water hauling - Transporting large amounts of water, sometimes in the event of an emergency. Bulk hauling often involves quickly moving several thousand gallons to the location where it is needed, and often it is the only way to transport massive quantities in a short time span.
Cistern - A tank or other container used to hold water, sometimes employed to catch rain. Water hauling services are often hired to pump out and clean cisterns.
Most people do not realize the amount of work it takes to get fresh water through your pipes and into your home. In cities and towns, it is supplied by utilities that treat it so that it is potable. They then pump it straight to houses. Some people in rural areas rely on filtered wells.
Therefore, the actual physical hauling of potable water in bulk is often restricted to an emergency relief situation. In situations such as floods, hurricanes or catastrophic main pipe failures, water trucks may be used. In very rare cases, a house may have no hookup at all and be reliant on regular deliveries. Bulk hauling for residential purposes is governed by the DEP in the same way that mains water is, and states generally certify such companies on an annual basis. Haulers may also remove water from main leaks.
There are many non-emergency situations in which tanks of water may be moved. The market for bottled drinking water is a solid one.
Large swimming pools and ice rinks are often filled from tanker trucks. Landscape gardeners may order water to fill a pond or fountain. In all of these circumstances, a bulk quantity is needed quickly.
There are also situations when water needs to be removed from an area. Coal mines, for example, tend to fill with water if not regularly pumped. When foundations are excavated in areas with a high water table, they can also fill with water. Natural gas and oil drill sites may also have issues with water in bore holes. In these cases, companies are hired to haul water away.
Water is also used in a number of recovery processes, and tanker trucks may be used to transport it. This includes dust control and road washing. The trucks used for most hauling are high pressure pump trucks.
