Drilling a water well is new territory for most of New Hampshire and Maine customers such as the order of operations, major drivers of price and site preservation.  This quick primer will allow you to better understand the process of drilling a gravel/screened or Artesian/Bedrock water well.

This biggest question everyone wants to know is "how much is a new well going to cost?" Well, the answer depends first on a few key factors.

The 3 major costs of a new well are:

  1. Total depth of drilling (feet) needed to reach reliable water.

  2. Total depth of casing (feet) used. This is directly related to the depth to solid bedrock. Casing is 6" pipe set into bedrock to stabilize the top of your well. 

  3. Water yield (Gallons per Minute). A low yield usually means that the pump needs to be set deeper, using larger gauge wire, more poly pipe, a larger horsepower pump and motor, etc. 


Other drilling costs can including mudding, grouting, and a drive shoe.

Initial Phone Consult

First step is find out a little bit about your water needs. Some questions that we will have include: 


  1. Is this for a residential or commercial property

  2. What is your existing water situation (bad well, no well, not enough water, etc.)

  3. Is this a new construction or existing structure

  4. What is the lot size

  5. How soon are you looking to have a well drilled

  6. Location address

We’ll do our best to check neighborhood water wells for well depths, depth to bedrock including depth of casing used, and the well water yield. For well cost estimating purposes, these stats are usually good indicators of what you’ll face.

Of course, we don’t know what water lies beneath your property in advance of drilling.  Neighboring real estate can often differ dramatically on well depth and actual water produced.  Still, local well stats are often helpful guideposts in creating an estimate.


We will try to locate 3 neighboring wells as close as we can to the intended drilling location in order to get an estimated drilling cost. 

Costs include:

  1. Per foot drilling from the surface until enough water is reached for the intended property needs and use.

  2. Per foot of casing steel pipe we use to stabilize the hole we drill to tap water veins in bedrock for your water well. Casing also prevents surface water from contaminating your new well.

  3. The drive shoe attached to the bottom of the casing which prevents damage to the casing and forms a strong seal with the surrounding rock; 

  4. Mudding – (possible) mudding is necessary to solidify the area around the hole and involves mixing firm bentonite clay with the dirt surrounding your well.  Mudding is needed when the rock underneath your property is porous and/or there is a significant depth to bedrock (the distance from the surface to strong bedrock);

  5. Grouting – (possible) you also may need to grout your well to seal it off from surrounding real estate and others’ water wells.  If your well will be a short distance from a property line or a neighbor’s water well, count on needing to grout per state law.


Site Visit

Typically, before you choose Hartley Well Drilling as your water well contractor, we conduct a site visit to plan well location including distance from septic system, property lines and your residence or business, etc.


Once you smartly choose Hartley Well Drilling as your water well driller, we mutually sign a simple agreement outlining pricing, drilling date and other relevant details.


Drilling Your Water Well

On the day of drilling, we’ll set up a water well drilling rig and a road truck that feeds water to rig and carries casing and drilling rod.  These are very large trucks and we may need to trim a few trees to make room for our rig’s 50-60’ truck mast, but we do our very best to minimize our impact on your property.


As mentioned above, we do not know in advance how deep your well will be.  However, we will consistently and diligently update you concerning well depth and flow.


Installing Your Water Well Pump System

After we finish drilling your water well, we’ll run heavy-duty polyethylene sanitary piping from the well to your water well pressure tank.  We also bury a separate protective conduit from your water well to your well control box. 


Inside your home or wherever else your tank is located, we install a water pressure tank, control box electrical components.  Of course, we’ll do our best to re-use existing control equipment but can’t guarantee that those previous elements will serve you well and we’ll thus recommend the best course of action to ensure long-lasting results.


Payment and Financing

Payment is due at the time services are rendered and we’ll send you an invoice accordingly.  



The Hartley Well Drilling crew prides itself on respect and not-so-common courtesy, especially regarding your property—both before and after we leave it.


Also understand that our main sources of business are word-of-mouth referrals and repeat customers.  We’ll always do our bottom-dollar best to get you the most well for your money without over-drilling just to make an extra buck.

"Employees needed to operate and maintain public and private drinking water."
