This rate schedule applies to services for single-family residences, single-family with guest house, and individually metered homes. For more details and to view total water tier rates as shown on your bill, go to Schedule A – Single-Dwelling Unit Residential Customers.
Your residential rate has four tiers and each tier has its own rate. Tier 1 represents indoor, basic needs use which is met by the lowest cost water sources. All customers receive 8 HCF monthly in Tier 1. Tiers 2 and 3 are for outdoor use and are allocated on lot size (five lot sizes); temperature zone (low, medium, and high); and season (summer and winter). These tiers are based on the higher cost of providing more expensive purchased water. The cost for Tier 4 comes from the most costly sources of water supply.
| Tier | Use | Description |
|---|---|---|
| Tier 1 | Basic indoor use | Least expensive water sources |
| Tier 2 | Efficient drought resistant outdoor water use | Some expensive water sources |
| Tier 3 | Above average outdoor use | More expensive water sources |
| Tier 4 | Excessive use | Most costly water sources |
During the winter, tiers are based on lot size only. All temperature zones receive the same amount of water. For the summer, hotter temperature zones are provided a slightly higher allotment to meet the needs of higher temperatures.
