Grafton Waterworks Water Company

YOUR SOURCE OF WATER
The Grafton water system obtains its supply from groundwater drawn from six active production wells distributed throughout the Village. All six municipal wells are completed in the Niagara dolomite aquifer and range between 500 feet to 600 feet deep. Each well feeds into a common distribution network divided into east and west pressure zones, roughly separated by the railway tracks running north to south through the Village. These six wells can pump up to 5.2 million gallons daily. Based on 2016 data, the Water Utility averaged 1.04 million gallons per day with peak demand reaching 1.7 million gallons in a 24-hour period.

WATER QUALITY AND TREATMENT
The water is generally high-quality, though in certain locations treatment is applied to enhance characteristics and meet safety standards. Fluoride is added at all wells to prevent dental decay, while phosphates are added at three wells to reduce red water and scale formation. An air stripping process has been implemented at two wells to remove low levels of volatile organic compounds (VOCs). Alongside VOC treatment, chlorine is added to all wells for disinfection purposes. The Grafton water supply contains approximately 22 grains of hardness, so the Water Utility strongly recommends using privately-owned water softening systems.

UTILITY PLANNING AND CONSERVATION
The Water Utility continues planning future system improvements following guidelines from our Water System Master Plan update completed in January 2016. This updated Plan provides a "roadmap" for ensuring adequate municipal water service through 2035. Water conservation remains essential for maintaining reliable, quality water throughout the Village. The Water Utility does not offer seasonal sprinkling credits for increased usage. Residents with higher summer water consumption may install a water-only deduct meter.

1. Where does Grafton Waterworks water come from?
   Grafton Waterworks supplies groundwater to Grafton, Wisconsin.
2. Does Grafton Waterworks test its tap water?
   Yes. Like every public water system, Grafton Waterworks must test its water under the federal Safe Drinking Water Act and publish an annual water quality report (Consumer Confidence Report). Ask the utility for the latest report or look for it on its website.
3. How do I contact Grafton Waterworks?
   Call 262-375-5300 or visit 860 Badger Circle, Grafton, WI 53024, or use the contact options on the utility’s website.
4. Does Grafton Waterworks water contain lead?
   Water usually leaves the treatment plant without lead. Lead can enter tap water from older service lines, solder and brass fixtures inside homes, especially when water sits in the pipes. Run the tap before drinking if water has been sitting, and ask the utility about lead testing and service line records.
5. Is Grafton Waterworks water hard?
   Hardness depends on the source and changes over time. The annual water quality report lists hardness, or you can test it at home. If it is above about 7 grains per gallon, a water softener sized to your measured hardness will stop scale and spotting.
