Plumber Serving Olathe, Kansas
Olathe is one of the few places in Johnson County where two homes a few streets apart can have different water and sewer providers. That detail matters for plumbing: it changes who you call about the meter or the sewer main, which water-quality report applies to your water heater and fixtures, and sometimes what’s involved in a sewer repair. We sort that out at the start of every Olathe job.

Water and sewer in Olathe: which do you have?
Depending on the address, Olathe homes get water from either the City of Olathe or WaterOne, and sewer service from either the City of Olathe or Johnson County Wastewater (JCW). Your utility bill tells you which. The city notes that WaterOne serves some Olathe residences, and JCW asks Olathe residents to call 913-715-8520 to confirm whether a property is on its system.
Why it matters to a plumber: the two water systems publish separate water-quality reports. The City of Olathe’s water comes from the Kansas River alluvial aquifer near De Soto, and its 2025 Water Quality Report lists total hardness of 150 mg/L (about 8.8 grains per gallon). WaterOne’s 2026 Water Quality Report lists an average of 135 ppm (about 7.9 grains per gallon). Both are “hard” water, so tank flushing and tankless descaling matter either way.

In Olathe, Municipal Code 13.05.010 defines the sanitary sewer service line as running from the building to and including the connection to the public main, maintained by the property owner. The city does not locate private sewer service lines, so they won’t be marked by an 811 request. The city locates water mains, service lines from the main to the meter, and sewer mains, but the line from the meter to the house, irrigation lines and sewer service lines are the homeowner’s.

Permits in Olathe
Olathe issues its own permits for work inside city limits. The city’s residential code amendments (OMC 15.04.080) exempt only stopping leaks, clearing stoppages and repairs that don’t replace or rearrange valves, pipes or fixtures. Water heater replacements, repipes, water line and sewer replacements need a permit. Emergency repairs can go ahead, with the permit application due the next business day.
Anyone pulling a plumbing permit in Johnson County needs a Johnson County contractor’s license; you can check any contractor on the county’s licensed contractor search.

The housing-age table above is from the Census ACS. Age alone does not diagnose a problem, but it helps explain why some streets see more laterals and shutoff calls than others.
