Fire pumps are used to increase the pressure of water sourced from a municipal underground water supply piping network, or a static supply (e.g., tank, reservoir, lake). A fire pump is a centrifugal- or positive displacement- pump that has been tested and listed by a third-party testing and listing agency, such as UL or FM Global specifically ...

An irrigation sprinkler (also known as a water sprinkler or simply a sprinkler) is a device used to irrigate (water) agricultural crops, lawns, landscapes, golf courses, and other areas.

The need for a water pressure booster pump can also arise after the installation of a backflow prevention device (BFP), which is currently mandated in many municipalities [where?] to protect the public water supplies from contaminants within a building entering the public water supply.
Backflow prevention device. The simplest, most reliable way to provide backflow prevention is to provide an air gap.An air gap is simply an open vertical space between any device that connects to a plumbing system (like a valve or faucet) and any place where contaminated water can collect or pool.
2. Free flow at waste valve 3. Outlet – delivery pipe 4. Waste valve 5. Delivery check valve 6. Pressure vessel. A simplified hydraulic ram is shown in Figure 2. Initially, the waste valve [4] is open (i.e. lowered) because of its own weight, and the delivery valve [5] is closed under the pressure caused by the water column from the outlet [3].

A small center pivot system from beginning to end. Irrigation equipment can also be configured to move in a straight line, where it is termed a lateral move, linear move, wheel move or side-roll irrigation system. [11] [12] In these systems the water is supplied by an irrigation channel running the length of the field. The channel is positioned ...
Often sewer maintenance trucks need water to flush out sewerage lines and fill their tanks on site from a hydrant. If necessary, the municipal workers will record the amount of water they used or use a meter. Fire hydrants may be used to supply water to riot control vehicles. These vehicles use a high-pressure water cannon to discourage rioting.
