Remote Power Water Pumps
People who's homes are on city water systems rarely need worry about how water reaches their faucet. Anyone living in a rural area with a private well, or in a cabin with no well and perhaps no running water, will run into a number of situations where owning an electric pump is either a great convenience or a necessity. Virtually any pumping need can be met with a low voltage DC powered pump. Anything from transferring heating fuel into a storage tank to supplying household water from a nearby stream can be accomplished with an alternative energy powered pump.

Small DC powered pumps are available for a variety of intermittent use needs. For homes running on a water holding tank system, a small pump can be used to transfer water from a transport tank to the holding tank. Using a pump is certainly a more convenient method than old fashioned hose siphoning. Many of the same types of pumps can also be used for transferring diesel heating fuel into a storage tank (although the same pump obviously shouldn't be used for both).
Intermittent use pumps often operate in an "always on" style, with removable wiring clips to attach to the power source. When the pump is attached, it will run. When the clips are disconnected, the pump turns off. Since the pump would only be used for specific "on the spot" tasks, connecting and disconnecting the wiring clips should prove convenient. Many of these pumps can be attached inline in a transfer hose, or can be submerged in the transfer tank, with a hose only attached to the outlet.
Pressure systems are generally installed on household water supplies. For households running on a holding tank water system or a low yield well, setting up a pressure system will boost water pressure at the household faucets. A water pressure system can operate with either an on-demand pressure pump, a pressurized water tank or a combination of the two.
Water & Utility Pumps
On-demand pumps are equipped with built-in pressure switches, allowing them to automatically turn on when water system pressure drops, and shut down when pressure reaches cut-off level. For systems running on a holding tank, an on demand pump is ideal for circulating water from the holding tank to the household water system. For a system running on a private well, a holding tank with a float switch can be installed after the well outlet, and the pressure pump can be installed between the holding tank and the household water system.
A pressure tank system can operate either from a well pump or an on-demand pump. With a well system, a pressure switch would be installed between the well and the pressure tank, cycling the well pump as needed to keep the pressure tank filled above a certain pressure level. With a holding tank, an on-demand pump can be installed between the holding tank and the pressure tank. The on-demand pump will fill the pressure tank from the holding tank, and the pressure tank will supply water pressure to the household plumbing.
For remote homes near a running stream, river or a clean pond, a surface pump can be used to transfer water from the stream to a top-inlet holding tank equipped with a float switch. The float switch will run the pump whenever the holding tank water level drops below a set level. Surface pumps can also be used on shallow water wells, where the water level is within 20 feet of ground level.
Many surface pumps are designed to push water over fairly long distances, and often hundreds of feet above the level of pump installation. This makes them well suited for supplying water to outlying buildings, fields or a house situated on a hill above an available water source.
Since DC pumps can be run directly from solar panels or wind generators with the use of special pumping controllers, they can also be installed in fairly remote locations for livestock watering stations.
For wells more than 15-25 feet deep, a surface pump would be far less efficient than a submersible model. All pumps push water out much more efficiently than they draw it in. In areas where water tables are fairly far underground, submersible pumps are the only choice for running a well water system.
A deep well pump will not be suited for applications requiring water to be pumped over long distances or up significant heights, unless a surface pump is also installed to assist with the load. However, for household systems or remote livestock watering stations where the deep well is within a few hundred feet of the water outlet, a deep well pump will operate quite well on its own.
