Well Driller List

State rules

Maine

Maine licenses well drillers and pump installers through the Maine Water Well Commission, also called the Well Drillers' Commission, at the Center for Disease Control and Prevention. The commission's page says it protects drinking water and groundwater by setting standards for well location and construction and minimum requirements for well driller and pump installer licensure. It investigates complaints under the Well Drillers and Pump Installers Rules, 144 CMR 232. The clerk contact printed on the page is DWPlicensing.dhhs@Maine.gov and (207) 287-2070. The page lists apprentice, journeyman, and master well driller exam applications, plus a renewal form. Licensee rosters are published separately. This record does not copy names from them.

Title 32, section 4700-I, says an applicant submits a written application on a commission form. A person who holds a license must be in the charge of a licensed well drilling company or pump installation company in order to practice. A company license is valid only while the company employs at least one licensed master well driller, for a drilling company, or one master pump installer, for a pump company. The commission licenses master and journeyman well drillers and master and journeyman pump installers. A master well driller needs at least three years and an average of 1,000 hours a year as a journeyman for each of those years.

The same section says well drillers, geothermal heat exchange well drillers, geothermal heat exchange well pump installers, and pump installers are licensed annually, and that all licenses expire on December 31. License fees are set by the commission at a level sufficient to recover reasonable costs, including examinations, and the statute says no license fee is required for an apprentice well driller or apprentice pump installer license. The commission page points applicants to CertTracker, the online system for contact information, experience, training hours, and renewal. Journeyman and master exam applications are linked from that page.

A property owner should ask whether the person on site is a master or a journeyman and whether the company license is backed by a master in the right trade. Location and construction standards are part of the commission's charge, so the hiring questions include where the well will sit, not only who holds the card. Complaints about the rules go to the commission. The page says licensed lists are for Maine only. Fees printed on a renewal form are not copied into the fee field of this record. The commission page and the statute are the two official starting points.
