Water and Wastewater Rate Changes

The Meridian Metropolitan District has adopted modifications to its water and wastewater rate structure. Changes take effect during the January 2023 billing cycle and are part of our long-term plan to fund system improvements and enhance the reliability of our water system. Additionally, new monthly water budgets and surcharges are being implemented to promote water conservation.

How will my monthly bill change?
The amount of water included in the monthly service charge has decreased to encourage conservation and keep bills lower for those who are most efficient in their use.

The $16 monthly wastewater service charge has increased to $16.80, and the volumetric rate increased from $6.89 per thousand gallons used to $7.23 per thousand gallons used. This 5 percent increase covers wastewater system upgrades and rising treatment costs.

Most single-family residential customers will see their monthly bills increase an average of $9.55 and will notice higher bills during warmer months, when water use increases.

Single-family residential customers will shift from an annual water allotment system to monthly water budgets, and a new surcharge structure has been implemented.

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 of providing safe and clean drinking water to your home or business.


The Meridian Metropolitan District 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 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 recycle strategy provides a sustainable source of irrigation water for Meridian Metropolitan District and is the backbone of our conservation strategy.

Wastewater Treatment

Wastewater treatment takes on a whole new meaning at the Meridian Metropolitan District. After our wastewater has been treated, it is returned back to Meridian Metro District Irrigation system. This design insures that not only is our wastewater treated to the highest quality standards, it is 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.
