Where Port Washington gets its water
Port Washington is served by the City of Port Washington Water Utility. It treats Lake Michigan water at its own filtration plant, opened in 1949, fed by an intake that reaches 2,100 feet into the lake and ends in 30 feet of water.
The utility tests for hardness but publishes no figure.
The utility lists hardness among the things it tests for, but no figure appears in its 2025 water quality report or on its water utility page. There is no published Port Washington number to cite, and we are not going to borrow a neighbor’s.

What Port Washington homes usually need
- Free quote by phone
- Installed by a licensed WI plumber
- Softeners retested to zero
$3,950 installed for the ZeroGrain One: softener, activated carbon and the reverse-osmosis drinking tap. Installation by an independent licensed Wisconsin plumbing contractor is in that number, not added to it, and the date is set once the equipment is in hand and approved for use in Wisconsin (SPS 384). What a softener costs explains what the $3,950 includes. Swapping out an old unit is replacing a softener; the drinking tap is reverse osmosis installation.

Questions
Port Washington water questions
Anything that is not here, ask it on the call.
Softening removes hardness minerals. It is not a health or safety treatment and we do not market it as one. On a private well, Wisconsin’s state-certified lab tests for bacteria and nitrates are a separate matter and not something we sell.
A lake plant with a long history
The utility dates to 1901 and the filtration plant to 1949, and the intake that feeds it runs 2,100 feet into the lake. The plant averages about 1.24 million gallons a day, and an upgrade to it was scheduled to finish at the end of August 2026.
What the quote starts from
With no published figure, the call covers the house, the fixtures and what you notice, and the plumber reads hardness, iron, chlorine and TDS at your tap on install day before anything is connected. On lake water softening matters less, and the call tells you plainly whether the whole-home system, RO tap included, earns its place.
How does the quote work in Port Washington?
There is no published Port Washington figure, so we start from your house, not from a catalog: the fixtures and what you notice. One short call covers it, at no charge. If what we hear on the call points to softening, we size it from your household and the plumber programs it to the hardness read at your tap; if it points away from softening, the call says so plainly. On install day the plumber reads hardness, iron, chlorine and TDS at your tap before anything is connected, and on a softener install retests hardness at the end so you watch it read zero.
