Water Treatment Services

It’s hard. Published figures for the area run roughly 8 to 11 grains per gallon depending on your provider and the season — well above the national average. You see it as spotted dishes, film on the shower door, crusty faucet heads, soap that won’t lather, and scale quietly building inside your water heater. None of it is dangerous. All of it costs you money slowly, mostly in appliances that die years early.

It’s treated with chloramine, not chlorine. Denver Water has used chloramine since 1918. It’s more stable than free chlorine and keeps water protected across a large distribution system — but it is considerably harder to filter out, and that changes which equipment actually works here.

Here’s the part most homeowners never hear: standard activated carbon removes free chlorine easily but barely touches chloramine at normal household flow rates — testing puts it under 20% removal. Catalytic carbon, a different media entirely, is what actually does the job.

So a bargain filter advertised as “removes chlorine” can be close to useless against what is actually in Littleton’s water, and the homeowner has no way of knowing. That is the most common mistake we see, and it is why we ask what is bothering you before we recommend anything.
