Water Softener & Filtration Installation in Columbia, MD
Columbia homes get slightly to moderately hard water from Howard County. We soften it, remove the disinfectant and polish your drinking water for $2,499 installed.

What is in Columbia's water
Howard County buys its water from Baltimore City and WSSC, so hardness is slightly to moderately hard depending on your neighborhood and the disinfectant is free chlorine. Columbia homeowners mostly want better-tasting drinking water and protection for newer appliances.
Seasonal changes
Check the county's annual report.
Lead and older plumbing
Historic Ellicott City has some of the oldest housing in the region. Lead does not come from the treatment plant.
PFAS: Ask for the latest county PFAS monitoring results. Reverse osmosis at the kitchen tap addresses PFAS regardless of source.

Columbia water questions
How hard is the water in Columbia?
Columbia is served by Howard County Bureau of Utilities. We expect about 3 to 7 grains per gallon, which is slightly to moderately hard. Baltimore reservoir water tends to be softer than Potomac water, and WSSC-supplied areas run moderately hard. Confirm in the county report.
Does Columbia tap water contain chloramine?
Howard County is understood to use free chlorine rather than chloramine, so a standard carbon stage works and we confirm the current disinfectant before ordering media.
How much does a water softener cost in Columbia?
$1,899 installed for a metered softener with catalytic carbon, or $2,499 with an under-sink reverse osmosis system. That covers equipment, a licensed plumber's installation and startup for a standard install; we quote any extras before booking.
Do you install in Columbia townhomes and condos?
Townhomes, yes, usually with a compact single-tank softener in the utility closet. Condos where the building supply cannot be modified get an under-sink reverse osmosis system, which handles drinking water taste, lead and PFAS without touching shared plumbing.
Is Columbia water safe to drink?
Yes. Howard County meets federal and state standards, and we will never claim otherwise. A home system addresses comfort (hardness, disinfectant taste and smell) and, at the kitchen tap, contaminants that enter from home plumbing such as lead.
