What Is A Well Inspection Checklist?

A well inspection checklist is a list of the various well components and functions that need to be inspected to assess the overall condition of a well. A good well inspection checklist should take into consideration the type of well to be inspected.

3 Types Of Wells

When inspecting wells, it’s important to first consider the type of well being inspected. Wells can be categorized into three main types.

Driven Wells

Also called sandpoint wells, these are built by driving a pipe into the sand. They use shallow groundwater as a water source.

Advantages of a driven well

  • Cheap
  • Easy to construct

Disadvantages of a driven well

  • Can only get shallow water
  • Easily contaminated

Dug Wells

Also called bored wells, these are built by digging a hole in the ground. They use shallow groundwater as a water source.

Advantages of a dug well

  • Large diameter
  • Can get water from sand, silt, clay

Disadvantages of a dug well

  • Possibly no water during droughts
  • Easily contaminated

Drilled Wells

Drilled wells are built by using a rotary-drilling machine. They use deep groundwater as a water source.

Advantages of a drilled well

  • Can get water 1000 ft deep
  • Lower risk of contamination

Disadvantages of a drilled well

  • Requires installation of casing and screen
  • Requires sealing of space around casing

What Does A Well Inspection Include?

A well inspection includes checking all of the well components, water pressure flow rate, water level before and during pumping, pump motor performance, pressure tank performance, and well water quality.

Well inspectors measure the volume of water pumped and the rate at which the pump works. They take note of when the pressure tank is signaling the pump and when the pump doesn’t produce water as signaled. They also test for coliform bacteria and nitrates to ensure the potability of water or it’s safety for use.

Top 3 Well Components to Check

Well Cover

a) For a dug well

  • Is the well cover attached to the casing?
  • Is the well cover vent screened and facing the ground?
  • Is there nothing on top of the well cover?

b) For a drilled well

  • Is the well cover in good condition?
  • Is the well cover pest-proof?
  • Is the well cover sealed tight?

Well Casing

a) For a dug well

  • Remove the lid to inspect the inside of the well casing
  • Check for damage or rust on the outside of the well casing

b) For a drilled well

  • Do not remove the lid to inspect the inside of the well casing
  • Check for damage or rust on the outside of the well casing

Annular Seal

  • Check if annular seal has shrunk or collapsed
  • Fill gaps around annular seal with bentonite

Aside from those mentioned above, the other well components to check are the following:

  • Capacitors
  • Electrical wires
  • Torque arrestors
  • Pump pressure switch
  • Check valves
  • Pitless adapter
  • Pipe fittings

Why Use A Well Inspection Checklist

Since there is so much to do, a well inspector might forget to check a major component or conduct an important test. Missing these inspection items can lead to the well malfunctioning. To avoid water well problems, use a well inspection checklist to keep track of everything.

If a homeowner is planning on inspecting a well themselves, they should have a well inspection checklist to guide them through the inspection process. Since most residential well owners aren’t certified well inspectors, they need a well inspection checklist to ensure that their inspection is as comprehensive as possible.

How Do You Check A Well System?

Site managers or well inspectors can check a well system by conducting a well yield test to get an estimate of the water pressure flow rate.

8 Steps Of A Well Yield Test

  1. Turn on the water at a plumbing fixture.
  2. Measure the flow at the plumbing fixture.
  3. Check if the pump is running continuously at the water tank.
  4. Time how long the plumbing fixture is running water.
  5. Try running 150-300 gallons of water.
  6. If water runs, record number of gallons produced.
  7. If water pressure decreases, measure the flow again.
  8. If water did not run and water pressure did not decrease, compare the number of gallons against standard water volumes.

How Do You Maintain A Well?

For well maintenance, a well inspector should check the well cover, the location of the well casing, the location of the well, the storage of hazardous materials on the property, and the seal of the abandoned well, if there is one.

Should You Have Your Well Inspected?

Contact a well inspector if there are problems with the well’s mechanisms or the water coming from the well. An annual water test is also recommended.

Well Inspection Checklist: Industry Use-cases

Industries with high water consumption include the automotive manufacturing, semiconductor manufacturing, textile industry, and beverage sectors. 

A well inspection checklist is a must for a car manufacturer since multiple stages in the production process use water. In the automotive manufacturing industry, water is used for surface treatment and coating, paint spray booths, air conditioning systems, and boilers.

In the semiconductor manufacturing industry, 2000+ gallons of ultrapure water are needed for a single 8-inch wafer (or 100 chips). A semiconductor producer should have a well inspection checklist to ensure that water has been purified according to the specifications.

For the textile industry, the most water-intensive part is wet processing. The steps of wet processing are sizing, desizing, scouring, bleaching, dyeing, printing, and finishing. Since large amounts of water are required to remove excess chemicals between steps, a fashion company would benefit from an intuitive, digital well inspection checklist.

In the food and beverage industry, common beverage ingredients like sugar, barley, and coffee are made by using a lot of water. Each type of beverage has its own water requirements. For example, both a pint of beer and a glass of orange juice use 45 gallons while a glass of wine only needs 32 gallons. A beverage company can use a well inspection checklist to facilitate effective water management, which will, in turn, improve overall operations.
