Who needs a certification

In Iowa, installing and repairing well pumps and water distribution systems, including pressure tanks and pressure switches, counts as a regulated well service.

State law requires well contractors to be certified by the Iowa DNR, and the certified person must be on site while the work is done.

A well owner may do their own well work, but must do it personally and cannot hire or barter with a non-certified person. Owners must follow the same rules as contractors.

Iowa certified pump installers can install and repair pumping and water distribution systems and can plug all types of wells.

How owners check a certification

You can confirm a contractor is certified by looking up their name on the Search Well Contractors page of IWIS for the type of work you need.

Non-certified contractors are not legally allowed to perform well services in Iowa, so check that the person you hire is on the DNR lists.

Iowa DNR says to always have a contract when hiring anyone for well services.

A certified contractor may still lack the equipment or experience for every job, so choose carefully.
