Property Tax Invoices

Beginning July 1st, 2020, the City of El Cajon began invoicing for sewer service on the property tax bill sent by the County of San Diego. Notification was sent to renters at that time to serve as notice that the sewer bill charges would be invoiced on the property tax bill. 

The amount due each year for sewer services charges, for the 12-month billing period from July 1st to June 30th, will be placed on and paid with the property tax bill from the County of San Diego. 

You will need to contact your landlord to determine what sewer charges you may be required to reimburse to them directly. 

How Are Sewer Charges Calculated?

Fixed Winter Average Accounts (most single-family residences)

• DEFINITION

Fixed Winter Average (FWA) = the average of the water usage from November through March

• FORMULA

Annual Sewer Charge = ((FWA x Consumption Charge) + (2 x Monthly Base Charge)) x 6 

Consumption-based Accounts (includes commercial and multi-family) 

Although most single-family residences are billed on an FWA, there are accounts that are billed like commercial and multi-family accounts, based on their full annual water consumption.

• DEFINITION

Total Consumption = all water usage from May through April

• FORMULA

Annual Sewer Charge = (Total Consumption x Consumption Charge) + (12 x Monthly Base Charge)
