$ 97.45What Well Protectors Do
A well protector is the vertical enclosure that surrounds the above-ground portion of a monitoring well casing. It prevents vehicle collisions from shearing off the well head, deters tampering, and marks the well location visually. Regulatory compliance at most monitoring sites requires a protective enclosure around every well that extends above grade.
Steel vs. Aluminum Lids
Steel lids offer maximum security and impact resistance. Best for sites near roads, parking areas, or anywhere vehicle contact is possible.
Aluminum lids are lighter and corrosion-resistant. Better for sites where the protector is in a non-traffic area and long-term rust resistance matters more than impact strength.
Available Configurations
Square protectors for 4”, 6”, and 8” well casings, all 5 feet tall. Top kits available separately if you already have the post installed and need a replacement lid.

FAQ
Do I need both a well protector and a well plug?
Yes. The protector shields the above-ground casing from physical damage and marks the well location. The plug or cap seals the well opening against contamination. They serve different functions and are both typically required by regulation.
Can I buy just the top/lid?
Yes. Top kits with locking lids are available separately for 4” well protectors if you need to replace a damaged lid without removing the entire enclosure.
