Groundwater wells may seem simple, but there are a variety of useful components that can help well owners protect their investment and optimize performance of their system.
|Well component||What does It do?||How does It work?||Do you have one?|
|Pump Protector||It protects submersible pumps from burning out due to low yield or low water levels.||It monitors the pump’s electrical current and automatically trips a switch to turn off the pump if it runs too long.||These are recommended for all wells, especially shallow wells or wells with known supply issues.|
|Pressure Tank||It provides pressure for household or irrigation use. Sizes range from 10-200 gallons; average size is 44 gallons.||It maintains a constant water pressure and turns the pump on once a set volume is used. For example, a 44 gallon tank has a drawdown of 16 gallons.||Most well systems have one. Most commonly they are small, blue metal tanks. They are often confused with a storage tank, but they are much smaller.|
|Storage Tank||It stores water for peak household or irrigation demand and allows the pump to gradually fill tank. Sizes range from 2,500-6,000 gallons.||A float switch triggers pump once the water in the tank gets below the set level. Storage tanks reduce stress on the pump.
|Storage tanks are especially useful for wells in drought-prone aquifers or in formations with low yield. They also can be filled by external supplies in emergencies.|
|Water Softener||Water softeners are a common treatment system for “hard” water that reduces the amount of calcium in the water.||It uses a chemical reaction to substitute calcium ions for either sodium or potassium ions (not as likely to leave deposits in pipes). Often there is a charcoal filter incorporated as pretreatment.||Water softeners (even those with charcoal filters) do not remove harmful bacteria or nitrates and do not reduce total dissolved solids.|
|UV Light System
||UV light systems neutralize harmful bacteria without changing the taste of the source water.||Water passes through pre-filters to remove particles that would create shadows where bacteria could hide then it goes through a light tube where the UV rays neutralize the remaining bacteria.||The UV light bulb should be replaced annually to maintain effective treatment. Pre-filters will need to be cleaned/replaced throughout the year.|
