Water Rates
During the rainy season, when the city’s water supply is at its peak, residents and commercial businesses will enjoy a low off-peak rate.
During the drier months, when demand on the water system is high, rates will increase by about 15 %, to reflect the added cost of supplying water to the city.
This seasonal rate will help us meet our greenest city goal of reducing water consumption by 10 %, which has two benefits for all residents:
• Reduce the strain on our existing water system, eliminating the need for costly system upgrades that could lead to higher utility rates.
• Help us live within our water means, ensuring that all residents have access to abundant, safe, clean water, no matter how much the city grows.
