Water and Wastewater Rates

Each Moulton Niguel 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 result in higher rates as the amount 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

For commercial customers, your water budget is based on a rolling average of the current month and the same month in the prior two years. Each month’s usage is weighted by the number of days in that bill to account for the potential difference in meter read dates for the different years. Water budgets for commercial customers shall be calculated such that a minimum budget of one billing unit shall be provided. For commercial customers with less than 3-years of data, the water budgets are calculated as follows: (a) for the first year, the customer’s budget is equal to water used; and (b) for the 2nd year, it is an average of current and the previous year’s usage in that month (e.g. February 2021 and February 2022) weighted by the number of days in each bill period.
