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.
Commercial Wastewater Service Charges
The rates for the District’s monthly wastewater service charges are structured to meet the District’s costs to operate and maintain its wastewater collection systems. MNWD’s rate structure consists of three customer classes: residential, multi-family, and commercial. Within the commercial customer class there are four subclasses of customers:
- Commercial Class 1 – Typical users include: banks, car washes, churches, department and retail stores, laundromats, professional offices, schools, and colleges
- Commercial Class 2 – Typical users include: beauty and barber shops, hospitals, convalescent facilities, repair shops, service stations, and veterinary hospitals
- Commercial Class 3 – Typical users include: hotels with dining facilities, markets with garbage disposals, mortuaries, and fast-food restaurants
- Commercial Class 4 – Typical users include: restaurants, auto-steam-cleaning facilities, and bakeries.
Potable irrigation water budgets are calculated based on the amount of irrigated area per parcel, monthly evapotranspiration numbers, and a landscaping factor of 0.70, with the exception of public spaces which are calculated based on a landscaping factor of 1.0. Irrigation water usage within budget is billed at the Tier 1 rates noted in the table below.
Recycled water budgets are calculated based on the amount of irrigated area per parcel, monthly evapotranspiration, and a landscaping factor of 0.80. All recycled water use within budget is billed at the Tier 1 rates noted in the tables below.
For private fire protection services, monthly charges are based on the size of the connection as shown in the table below.
