Water Department

Over the years, we have dedicated ourselves to producing drinking water that meets all state and federal drinking water standards. We continually strive to adopt new and better methods for delivering the best quality drinking water to you. As new challenges to drinking water safety emerge, we remain vigilant in meeting the challenges of source water protection, water conservation and community education, while continuing to serve the needs of all our water users.

KU water supply is from groundwater. But what’s the difference between groundwater and surface water? 

Water supply for human consumption comes from two sources; groundwater and surface water. There are differences in surface water and groundwater quality. Each source of water has a unique set of contaminants and neither water source can ever be entirely free from water contaminants.

Groundwater…

…is located underground in large aquifers and must be pumped out of the ground after drilling a deep well. Filtration through the soil helps clean groundwater. Groundwater is water contained in or by a subsurface layer of soil or rock.

Groundwater is the source of about 40% of the water used for public water supply. It provides drinking water for a majority of the rural population who do not have access to public water-supply systems. Some major cities rely solely on groundwater for all their needs.

Surface water…

…is found in lakes, rivers, and streams and is drawn into the public water supply by an intake.  Surface water can be affected by numerous physical variables such as topography, land cover, soil conditions, mineralogy, and ground-water conditions, all of which may be affected by geologic conditions.

2019 Water Report

We are once again pleased to present our annual water quality report covering all testing performed between January 1 and December 31, 2019. Click here to view the report.

For more information about this report, or for any questions relating to your drinking water, please call the Water Department at (920) 462-0233.

ppm (part per million)
Parts per million, or milligrams per liter (mg/L). Compared to the volume in an Olympic-size swimming pool (660,000 gallons), the volume in 1 ¼ two-liter bottles (2 ½ liters) represents 1 part per million.

ppb (part per billion)
Parts per billion or micrograms per liter (µg/L). Compared to the volume in an Olympic-size swimming pool (660,000 gallons), the volume in ½ teaspoon represents 1 part per billion.

pCi/L (picoCuries per liter of air)

The concentration of radon gas is not measured directly but rather by the radioactivity it produces. It is expressed in picoCuries per liter of air, or “pCi/L“. A Curie is a unit of radioactivity equivalent to 1 gram of radium and the prefix “pico” means a trillionth

Range (Low to High)
The highest and lowest concentrations found in KU water tested throughout 2019.

Maximum Contaminant Level (MCL)
The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.

Maximum Contaminant Level Goal (MCLG)
The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.

Maximum Residual Disinfectant Level (MRDL)
The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.

Maximum Residual Disinfectant Level Goal (MRDLG)
The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.

Conservation / Incentive Programs

There are a number of incentive programs available for homeowners when you upgrade your appliances, faucets, air conditioning, lighting, toilets, and more. Building a new home? There’s a number of incentives for you, too.
