Water Softener & Filtration Installation in Georgetown, DC
Georgetown homes get moderately hard water from DC Water, disinfected with chloramine. We soften it, remove the disinfectant and polish your drinking water for $2,499 installed.
What is in Georgetown's water
Georgetown gets DC Water's moderately hard, chloramine-treated supply. Historic plumbing is the real issue: many houses have been renovated several times, and we frequently find a mix of copper, galvanized and old brass. Lead-rated drinking water filtration is a sensible baseline.
Seasonal changes
Every spring DC Water temporarily switches to free chlorine to clean the pipes. The chlorine smell is strongest during those weeks.
Lead and older plumbing
DC still has lead service lines in many older neighborhoods, and DC Water runs a replacement program (Lead Free DC). If your home was built before 1960, treat lead as a real possibility until the service line is confirmed.
PFAS: Utilities that draw from the Potomac have reported low-level PFAS detections in routine monitoring. EPA finalized limits for PFOA and PFOS in 2024. An under-sink reverse osmosis system certified to NSF/ANSI 58 is the practical fix at the tap you drink from.

DC water is only moderately hard, so the softener conversation is about comfort and appliance life rather than heavy scale. The bigger issues for DC homeowners are chloramine taste and the age of home plumbing.

Homes in Georgetown
Georgetown townhouses date from the 1700s onward and often have brick cellars with limited headroom and no floor drain. We plan every install around drainage and access, and we use cabinet-style softeners that fit under a stair or in a pantry when needed.
What we usually install here
For rowhouses and single-family homes, a compact softener with catalytic carbon plus under-sink reverse osmosis. For condos and apartments, an under-sink reverse osmosis system certified for lead and PFAS is the right-sized answer.

Georgetown water questions
How hard is the water in Georgetown?
Georgetown is served by DC Water. The utility reports 4 to 7 grains per gallon, which is moderately hard. DC Water describes its water as moderately hard and publishes a range of 70 to 120 ppm, which is roughly 4 to 7 grains per gallon.
Does Georgetown tap water contain chloramine?
Yes. DC Water uses chloramine year-round. It is gentler on taste than free chlorine but harder to filter; catalytic carbon media is required. That is why we use catalytic carbon in every Georgetown whole-home system instead of standard carbon.
How much does a water softener cost in Georgetown?
$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 Georgetown 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 Georgetown water safe to drink?
Yes. DC Water 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.
