• wastewater

    Wastewater is a non-metered service, so we often get the question of how we calculate wastewater bills.

    Like most utilities, we calculate projected wastewater flows by using a formula for all residential customers. The calculation is designed to bill for water that runs down the drains and toilets and excludes, as much as possible, water used outdoors.

    We calculate an average daily unit (ADU) based on water use from December through February - when outdoor watering is lowest.

    Learn more about your wastewater bill and the calculation of ADUs.
