The Village is responsible for providing safe drinking water with 35 miles of the water distribution system, and operation and maintenance of five municipal wells and five water reservoirs. 
There are approximately 1,700 water main valves and approximately 500 fire hydrants.  On average, daily water consumption is between 850,000 and 1,200,000 gallons.  The property owner is responsible for maintaining their water service lateral from the service valve near the property line, to the structure.  Each building in the Village is required to be connected to the Village's water system.  A water meter is used to measure the water usage at each property. 

The meter is read quarterly and billed to each customer around the tenth of January, April, July, and October.  Bills are due within 20 days.

The PSC (Public Service Commission of Wisconsin) is the regulatory entity for the Village of Pewaukee Water Department and the Village follows regulations as provided by the PSC. If you have any questions regarding the PSC regulations please email the Village Treasurer.

Information about drinking water can be found on the Consumer Confidence Report.

Recent water samples indicate that there is a presence of Gross Alpha existing in the drinking water at one of our wells.  This is not an immediate risk, if it had been residents would have been notified instantly.  The Gross Alpha notice provides more detail.

Recent water samples indicated there was a presence of PFAS existing in the groundwater at one of our wells. The Village sampled the well and took offline promptly, awaiting test results. This well remains offline as the results were positive for PFAS. If this had been an immediate risk, residents would have been notified instantly.  The PFAS notice provides more detail.

The Village's waste water collection system includes approximately 34 miles of gravity sewer, nearly 1,000 manholes, and five sanitary sewer lift stations, which convey waste water within the Village, and finally to the Fox River Water Pollution Control Center in Brookfield for treatment and discharge to the river.  On an average day, about 1.5 million gallons of wastewater is pumped to the FRWPCC.  The property owner is responsible for maintaining the sanitary sewer service lateral from the sewer main to the structure.  Sewer charges are based on the actual water usage per property.  

The Village offers a sewer deduct meter for properties that use a significant amount of water outdoors. The sewer deduct meter bills for all water used but reduces the number of gallons charged for sewer. A quarterly sewer deduct service charge applies based on the applicable meter size. If you would like to have a deduct meter installed please click here. 

The Village charges a flat rate for stormwater.  Stormwater runoff is water that doesn't soak into the ground and drains into the storm system.  The flat fee is charged for the operation and management of the drainage infrastructure.
