Water and Wastewater Rates

The Meridian Metropolitan District has adopted modifications to its water and wastewater rate structure. Changes went into effect starting with the January 2024 billing cycle (reflected on February bills). These rate adjustments are part of our long-term plan to fund system improvements and enhance the reliability of our water and wastewater systems.

How does Meridian use the money you pay?

The rates you pay are investments in our infrastructure and fund our ability to continue providing clean and safe water to our community. The revenue generated from this year’s rate adjustments will go toward:

  • New Potable Water Infrastructure
  • Wastewater Treatment Plant Improvements
  • Enhancements to Operational Control Systems

Drinking Water

MMD treats and delivers potable drinking water that meets all federal and state drinking water regulations. Water professionals continuously staff and monitor the water system to meet our commitment to providing safe and clean drinking water to your home or business.


MMD provides irrigation services for a variety of purposes within its service area. This system is considered highly efficient and sustainable in its design. The irrigation system utilizes the District’s wastewater effluent (treated wastewater) as its main source of water. Treated water leaves the wastewater plant, is held in a 486 acre-feet reservoir, and is then recycled directly into the irrigation supply lines to water parks, golf courses, commercial properties, and other common areas. This environmentally responsible recycling strategy provides a sustainable source of irrigation water for MMD and is the backbone of our conservation strategy.

Wastewater Treatment

Wastewater treatment takes on a whole new meaning at the MMD. After our wastewater has been treated, it is returned to the MMD Irrigation system. This design ensures that not only is our wastewater treated to the highest quality standards, but it is also then used to water parks, golf courses, and other outdoor landscaping. As a result, we recycle 100% of our water. This represents a nationally recognized sustainable conservation strategy.
