Water and Wastewater Rates

Each MNWD customer is allocated a personalized water budget based on your individualized needs. The rate structure for water service fees has five customer classes: residential, multi-family, commercial, irrigation, and recycled. This structure is comprised of two components: a fixed monthly service charge and a variable volumetric water consumption charge.The rates for the fixed monthly Service Charge are established on the basis of the size of the water meter serving a property and are calculated to recover a significant portion of the District’s fixed costs. The rates for the variable Volumetric Charge are based on the number of units of water delivered to a property and consist of five tiers which results in higher rates as the level of water consumption increases.

* Classifications are subject to change upon inspection by the District in order to comply with the intent of MNWD’s Rules and Regulations and regulatory mandates
