How Lowering Pump in Your Well Can Help During Drought

What option to take when groundwater levels decline.

The United States Bureau of Reclamation has started drawing down the Yakima Basin reservioirs and an irrigation district is rationing water — two signs the drought has taken hold.

Groundwater levels may vary from one season to another with highest levels experienced in spring and lowest in late fall. Whenever there is , it is likely to leave many homesteads with decreased groundwater levels.

When groundwater levels decline significantly, the well owners may have to consider a number of options. The well may be deepened to reach lower levels than before or a new well may be drilled to get access to the groundwater. Alternatively, lowering pump to attempt reaching the low levels of water might be another option.

Having periods of little rainfall may reduce the recharge of groundwater, which brings the levels down. When the low rainfalls are coupled with warmer weather conditions, they cause increased vegetative evaporation as well as transpiration. This causes people to increase their water usage especially for outdoor applications such as watering gardens and yards.

Increased water usage puts more pressure to the already declining ground water levels. During drought, in the Yakima, Kittitas & Benton Counties  your well may be susceptible to failing.

Lowering the pump or not?

This is the first option:  consider when the groundwater level has declined is to have the pump lowered. By lowering the pump, it will be able to reach lower depths and draw water.

This is the second option: If your pump cannot be lowered the other option is to drill deeper into existing well. Sometimes this can be a greater expense than drilling a new well.

This is your third option: drilling a new well  replacing your old well.




Must know differences between Ground water and Surface water

Ground Water Vs. Surface Water


There are some incredible differences in the quality of groundwater and surface water. Every resource of water has a distinctive set of impurities. Groundwater stores nitrate and insect repellent chemicals, whereas surface water holds most microorganisms and other bacteria. Due to the interconnectedness of surface water and groundwater, these impurities may be shared between the two water sources.

What is Ground Water?

ground waterGroundwater is water that is found beneath the surface of the earth, which seeped down slowly by saturating rock or soil. This water is stored in secretive gaps and in the minute openings of rocks and other materials under the surface.

The supplies of groundwater in aquifers below the earth’s surface are amongst the most vital natural resources of the nation. This type of water is the resource of about 40 percent of the water exploited for public supply. It offers drinking water for over 97 percent of the rustic population who do not get access to public water-supply schemes. Between 30 % and 40 % of the water, employed in agriculture is available from ground water.

What is Surface Water?stream in yakima

Surface water is made up of all water that is uncovered to the atmosphere naturally, including ponds, creeks, rivers, reservoirs, lakes, oceans and seas. Furthermore, in this class are water wells and springs that which are influenced by surface water resources directly.

Surface water can be seen over the surface of the land in ponds, streams, lakes, marshes, or other fresh resources and are not salty in nature.

Difference between Ground water and Surface water

Excluding the location, one among the major differences between ground and surface water is that surface water moves much faster than ground water. This is for the reason that ground water comes across far more resistance while it moves in the course of the pores in soil than surface water experiences while it flows over the surface of the earth.

Surface water is influenced by many physical variables, like land cover, topography, mineralogy, soil conditions, and ground-water conditions, all of which may be influenced by geologic conditions. Surface water is as well, contaminated more easily than ground water. Filtration in the course of the soil assists clean ground water.

The hydrologic phase interconnects surface and ground water that indicates that they can pollute one another. As snow or rain falls on the surface of the earth, some water flows from the land to the lakes, rivers, streams, and seas. However, some water is as well, evaporated and sucked up by plants or continues to go down to turn into groundwater. Groundwater moves extremely slowly toward low regions such as lakes and streams, which end up in surface water once again. This cycle is constant and shows the way the surface and ground water are interrelated.

The normal quality of groundwater further varies from surface water. For any known source, its temperature, quality, and other constraints are less changeable over the time period, and, naturally, the range of groundwater constraints encountered is much superior to surface water.

At any given place, groundwater is inclined to be harder and more salty than surface water, but this is not at all a universal rule. It is also normally the case that groundwater turns into more salty with increasing depth.

While groundwater flows in the course of an aquifer, it is filtered in nature. This filtering, pooled with the long dwelling time underground, indicates that groundwater is generally free from infection-causing bacteria. However, a source of pollution close to water wells, can overcome these natural protections. Innate filtering also indicates that groundwater generally holds less undissolved solids and suspended material than surface water.

Washington State law requires decommissioning only by licensed well drillers

Must Read before decommissioning your water well

Every year, across the state, people and animals fall into abandoned water wells. These falls usually result in injury, and sometimes death. Any well, if not properly constructed or maintained, can pose safety and environmental problems.  Children, adults, and animals face a risk of injury or death if they fall into these wells.

Washington state law requires property owners to properly decommission abandoned groundwater wells. 

  • The landowner may be responsible for any injury or occurrence of groundwater contamination caused by an abandoned well not properly decommissioned.
  • Decommissioning of an abandoned well often means filling the entire casing of the well with concrete, but this or any decommissioning work must be done by a water well driller licensed in Washington state.

Cost of Decommissioning A Water Well

Costs to decommission wells will vary depending on the depth, diameter, and geology of the area. Special equipment may be required to remove old pumps and pipes from the well.

Your well driller will remit an intent of “Notice of Intent to Decommission a Well” to the Department of Ecology at least 72 hours in advance of the work along with a $50 fee for the decommission.



  1. The JET PUMP comes in two specific types, the shallow well and deep well jet pump.

  • The SHALLOW WELL JET pump has the jet mechanism installed in or on the pump at the ground surface. This pump will connect to the well borehole with only one suction pipe and has lift capability of no more than 25 feet.

 Figure 2 Deep Well Jet Pump

  • The purpose for the DEEP WELL JET pump is they have a water level deeper than 25 feet from the ground surface. This jet pump has two pipes within the borehole, one pipe is for suction and the other is return water to operate the jet unit, which when installed is below the water level. This pump forces water down one pipe, back up through the second pipe, and has lift capability from depths greater than 50 feet.
  1. The CENTRIFUGAL pump is specific for shallow wells because this pump has only one pipe that goes down the well borehole with only enough suction to effectively lift water no more than 25 feet.


                                                                        Centrifugal Pump

  1. The SUBMERSIBLE pump is the most popular well pump and can be used in both shallow and deep wells. These pumps are capable of pumping large volumes of water from deep wells with a power range from 1/3 to over 7.5 horsepower.

5 Tricks For Finding Old Wells On Your Property

5 tricks to finding an abandoned water well system on your property

Yakima Washington Old Water Well Locator

wellIf you live in an area where people use water wells, there may be an old unused well on your property. There are millions of them all over the United States. Abandoned wells should be properly sealed by a qualified licensed water well contractor for several reasons.

First, abandoned wells can provide a direct pathway for contamination into the aquifer, the same one you are using for drinking water. Often an abandoned well will have no well cap or the cap will be broken. This will allow bugs, rodents or objects into the well. Other times, the grouting around the well casing has deteriorated to the point that contaminated surface water can infiltrate the well. Abandoned hand dug wells not only present a contamination concern, they also can create a physical danger to family playing in the area.

Landowners should find the location of any old or out of service wells. Here are the 5 tricks:

  1. Pipes sticking out of the ground
  2. Small buildings that may have been a well house
  3. Depressions in the ground
  4. The presence of concrete vaults or pits, perhaps covered by lumber or metal plates
  5. Out-of-use windmills are likely to be located near an old well

Other clues can come from old maps, plans or property documents, information from neighbors and older additions to the homes. In the past, wells were commonly constructed in basements or under porches to keepmap the water pumps from freezing and to ease access in the winter.

Once a well is determined to have no current or potential future use, a qualified licensed water well contractor must properly abandon the site with the Washington State Dept. Of Ecology.

Do not attempt to seal an old unused well yourself! This requires special equipment and techniques to remove anything from the well and fill it with a special grout from the bottom up. Ordinary cement will not provide a sanitary seal for an abandoned well.

Estimating the Depth & Cost of your Water Well in Yakima

Water Well Contractor cannot tell you exactly to what depth they will drill or the exact amount of water that the well will yield.

The contractor estimates by utilizing the information of average depth for your area (zone) and knowledge of ground formations. In most cases water can be tapped from 100 to 300 ft while in some areas 500 to 1000 ft deep is normal.

In Two Easy Steps:

  1. The First cost for your water well will be the permit, which is a cost set by the Washington State Department of Ecology or if on Tribal Land, a permit is required through the Water Code Administration.
  2. The Second determining factor is the estimated cost of your well. The Drilling Contractors charge by the foot along with any drilling cost as well as pipe usage. It is important that your Well Contractor along with the Well Driller, is Licensed and Bonded in the State of Washington, with a reputable reputation. It is the Well Contractors duty to give a good faith estimate.

 If the water first tapped is adequate for your family, then drilling can stop. If not, then drilling may have to go deeper. (A family of four uses approximately 300 gallons of water each day).

Let us not say what we are, but let us prove what we are; by being 100% Owner/Operators, providing education, free diagnostic review with estimates along with an amazing 30-day customer support guarantee.

Purchasing a Home with a Water Well in Gleed

house-saveBefore purchasing a home you should require proof that your water well is of sufficient supply. If you are borrowing money from an institute such as a bank, sometimes they will require a test be completed. However, if you are purchasing on private contract seek assistance from a licensed water well drilling company before the closing of the sale. If a new water system or the upgrade of an existing system is necessary, through appropriate testing, part of the purchase price should be held in escrow to cover the expense.

The owner of a residential property with their own private water well systems should supply you (the purchaser) with information about the following:

  • Well Location and type of construction
  • Types of materials used in the construction including the pipes leading to the house
  • Age of the system and pump
  • Location of septic systems and its relation to the well
  • Is the water supply being softened and by what process
  • Is the present method of water adequate for your needs

There are many factors involved in the drilling of water well. Whether it is a deep well or a shallow well, it is a complex and difficult process that should only be attempted by a licensed professionals with the right equipment and ample experience. Drill rods can weigh several tons, different types of geological formations require different types of drill bits, and many other factors contribute.

You well need a dependable water supply for your present and future needs. An average household uses approximately 300-500 gallons of water per day. For a family of four, a domestic well should provide a dependable yield of 10 to 25 gallons-per-minute to supply all your water needs. Presently a domestic well can be used for lawn & garden watering, up to 1 half acre, giving a total usage of 5000 gallons-per-day

The State Of Washington requires water well contractors to be licensed and bonded. The state also requires the driller on site to have a valid Washington State License. Before the well construction can begin, a notice of intent to construct a water well must be applied and obtain through the Washington State Department of Ecology. While the well is-being-constructed, your licensed Water Well driller must remain at the drilling site.

What is a Well in Tieton

Water Wells 101: what you need to know


Groundwater is almost everywhere, supplying drinking water for over 50% of the United States and is an important component in many industrial processes. Groundwater is a source of recharge for lakes, rivers, and wetlands. The water table may be deep or shallow; may rise or fall depending on many factors such as; heavy rains or melting snow and heavy pumping of groundwater.

A Well is a pipe in the ground that fills with groundwater. This water can be brought to the surface by a pump. Shallow wells may go dry if the water table falls below the bottom of the well. Some wells, called artesian wells, do not need a pump because of natural pressures that force the water up and out of the well.

Saturated Zone is the area where water fills the aquifer, whereas the top of this zone is called the Water Table. The water table may be located only a foot below the ground’s surface or it can sit hundreds of feet down.

Aquifers are usually made of gravel, sand, sandstone, or fractured rock, like basalt. Water can move through these materials because they have large connected spaces that make them permeable. Water in aquifers can be brought to the surface naturally through a spring.

Groundwater Flow depends on the size of spaces that are between the soil and rock and how they are connected, which can be extracted through a well drilled into the aquifer and pumped out.
