💧 Celebrate National Drinking Water Week in Waukesha! 💧
It’s National Drinking Water Week, and there’s no better time to celebrate the clean, refreshing water we enjoy here in Waukesha! Whether you are filling up a reusable water bottle, keeping your garden green, or simply appreciating the reliable flow from your tap, this week is all about recognizing the value of safe and abundant drinking water.
In October 2023, the City of Waukesha made a significant transition by switching its drinking water source to 100% Lake Michigan water. This change means cleaner, softer water—approximately 60% softer than the previous groundwater supply. As a result, most Lake Michigan water users do not require water softeners, and many residents have already made the switch.
To help residents and businesses make the most of Waukesha’s new water source, the Waukesha Water Utility offers several rebates to encourage water conservation. These programs are available on a first-come, first-served basis, so it is best to act quickly!
Water Softener Removal Rebate:
Removing your water softener can save money and reduce salt use, thanks to the softer Lake Michigan water. Qualifying residents who remove and dispose of their softener can apply for a rebate.
Toilet Rebate:
Receive up to $100 per toilet when replacing older models (1993 or earlier) with WaterSense-labeled, high-efficiency toilets. For projects involving more than five toilets, check the Large Multi-Family / Commercial Toilet Rebate guidelines.
Shower Head Rebate:
Swap your old shower head for a WaterSense-labeled model and receive a $25 rebate.
Rain Barrel Rebate:
Install a rain barrel to capture water for your garden and get up to $20 back (limit of two rebates per household).
Custom Water Efficiency Projects:
Businesses and multi-family properties can receive up to $20,000 for approved projects that enhance water efficiency. Pre-approval is required before starting any project.
Large Multi-Family / Commercial Toilet Rebate:
Just like residential properties, businesses can receive up to $100 per toilet when replacing older models with high-efficiency, WaterSense-labeled toilets. Pre-approval is necessary before any changes.
To help conserve water and maintain efficiency, Waukesha’s Annual Sprinkling Ordinance (City Ordinance 13.11) is in effect from May 1 to October 1 each year.
Addresses Ending with an Odd Number: Water on Tuesdays and Saturdays
Addresses Ending with an Even Number: Water on Thursdays and Sundays
Permitted Hours: Before 9:00 a.m. or after 5:00 p.m.
Hand Watering: Allowed any day at any time.
Why These Times?
Watering early in the morning or later in the evening helps minimize evaporation, ensuring more water reaches your lawn and plants.
Water Wisely: Established lawns only need about one inch of water per week.
Time it Right: Set a timer as a reminder to move sprinklers.
Morning Routine: Water before 8:00 a.m. to minimize evaporation.
Avoid Night Watering: This helps reduce the risk of lawn diseases.
Lawn Maintenance: Raise your mower blade to at least three inches to protect roots and retain moisture.
Mind the Fertilizer: Overfertilizing increases water needs. Opt for slow-release, water-insoluble nitrogen for better efficiency.
Wind Awareness: Avoid watering on windy days to prevent water waste.
Sprinkler Positioning: Make sure sprinklers are aimed properly to avoid watering the roof, driveway, or sidewalk.
Better Sprinkler Choice: Use sprinklers with larger holes to reduce evaporation compared to fine-mist types.
Drip Irrigation: Use drip systems or soaker hoses for plants, trees, and gardens. Position soaker hoses upside down to minimize evaporation.
National Drinking Water Week is the perfect time to appreciate our clean, accessible water while also committing to conserving it. By following the city’s watering guidelines and taking advantage of available rebates, you can make a positive impact on both your utility bill and the environment.
