Wastewater Bill Zoomed

The Wastewater base facility charge is a monthly recurring charge and is calculated by multiplying $33.60 times your EDU assignment. For single family homes, the EDU assignment is 1. For multi-family homes, the EDU assignment is one times the number of units. For Commercial and mixed-use parcels, the EDU assignment is calculated by evaluating your historic usage over three years and dividing by 5010 (which is approximately what the average, single family residence uses). The Wastewater usage charge is calculated by multiplying $5.27 by the number of gallons shown under “Total Consumption” and divided by 1,000 (the $5.27 is charged per 1,000 gallons).
