Filtration &
Treatment

New Hampshire’s bedrock geology puts more into private well water than most homeowners expect. Arsenic, radon, iron, manganese, hardness, low pH and bacteria all occur naturally across the state, and none of them announce themselves at the tap.

Capital Well designs, installs and services water treatment systems built around what is actually in your water — not a one-size package.

We Start With a Water Test
Every treatment recommendation begins with a laboratory analysis of your water. Testing identifies which contaminants are present and at what concentration, which determines system type, sizing and media selection. Guessing at treatment wastes money and frequently fails to solve the problem.

Water Filtration Systems
Whole-house filtration removes sediment, iron, manganese, sulfur odor and taste-and-odor compounds before water reaches any fixture. Media and tank size are matched to your flow rate and contaminant load so the system regenerates on an appropriate cycle rather than running constantly.

Water Softeners
Hard water leaves scale in pipes, shortens water heater life and reduces soap effectiveness. A properly sized softener resolves all three. We size units to household demand and hardness level to avoid the excessive salt use that comes with an oversized system.

UV Water Purification
Ultraviolet purification neutralizes bacteria, E. coli and coliform without adding chemicals to your water. It is the standard solution after a positive bacteria test and a sensible precaution for any well with a history of surface influence.

Ongoing Service and Maintenance
Treatment systems need filter changes, media replacement and periodic recalibration. We service all makes and models, including systems we did not install, and offer scheduled maintenance so nothing gets missed.
