Your water bill includes the costs associated with providing water to your tap, 24 hours a day, 7 days a week. It includes a fixed Base Water Charge, a per-unit charge based on your water usage, a fixed Watershed Management Fee, and a fixed Capital Maintenance Fee.
Base Water Charge
Providing water to your tap 24/7 involves a network of support services. Your Base Water Charge includes fixed costs associated with your water service, such as maintenance, billing, customer support services, and other operational costs.
Water Use Charge
The Water Service Tier Charges show the per-unit cost of water used. One unit equals 748 gallons of water. Tiers are based on your water use, with Tier One being the least expensive. The more water you use, the higher your water tier. The tier system is designed to encourage water conservation.
Watershed Management Fee
The Watershed Management Fee is a fixed fee that pays for the sustainable management of our Mt. Tamalpais watershed, including vegetation management for fire prevention, protecting natural habitats, and maintaining recreational areas and the water quality of our reservoirs.
Capital Maintenance Fee
Marin Water is California’s first municipal water district, established in 1912. Many of our pipes are more than 100 years old. The Capital Maintenance Fee is a fixed fee that funds capital projects, including replacing old pipelines, tanks and other infrastructure that improve the overall reliability of your water service.
