The City of Olathe produces safe quality drinking water, meeting or exceeding all state and federal health and safety measures every year.

As surface water filters through the ground, it dissolves naturally occurring minerals, and picks up substances resulting from the presence of animal or human activity. The content of the water can also vary with the seasons. Given these diverse circumstances, the City treats the water accordingly to produce a high-quality product that is safe for customers.

Olathe’s water is obtained from four wells along the Kansas River near DeSoto. In 2018, 4.57 billion gallons of water was treated, averaging nearly 12.9 million gallons of water a day. In addition, more than 2,400 water samples were collected and tested from the river, treatment plant, and distribution system each month, almost 80 samples per day. In all, more than 90,000 tests are conducted each year to detect and remedy any health, safety or water quality issues.

“Our dedicated staff operates and maintains facilities where we test drinking water for 200 plus analytes, including 88 primary regulated contaminants and 15 secondary contaminants,” Environmental Services Director Joe Foster said. “The City has set a standard for great tasting, top quality, and safe drinking water and it is due to our more than 135 years of experience in the water industry.”
