The WWD is a public agency that distributes treated water to and collects sewage from nearly 4,000 customers.
The District bills customers every two months.  Usual mailing dates are the 15th of January, March, May, July, September, and November.
The bills consist of a water charge and meter service charge.

Effective July 1, 2008, the sewer service charges will no longer be billed bi-monthly.  Instead, the sewer charges will be billed thru the county's property tax bill.



The District gets its water from the San Francisco Water Department (SFPUC).  The SFPUC uses chloramine (a mixture of chlorine and ammonia) to disinfect the water.  Chloraminated water is safe for people and animals; however, precautions must be taken to remove or neutralize chloramine during kidney dialysis process, in the preparation of water for fish tanks and ponds, and for businesses requiring highly processed water.  Please ask District personnel for additional information.

The District bills customers for the actual units that are registered by the water meter.  Water meters are read bimonthly.  The District bills customers on arrears, so the current bill is for service for the previous two months (or partially if new customer of the District).

The water rate is currently $6.48 per unit, with one unit (HCF) equaling 748 gallons of water or 100 cubic feet.  There is no minimum charge.

The sewer service charge pays for water that goes down the drain(s), which needs to be treated in order to be released into the Ocean.  District's wastewater is processed by the City of Daly Cityís North San Mateo County Sanitation District (NSMCSD).

The sewer service rate is currently:  $9.87 per unit.  There is a minimum charge of 12 units annually or $118.44.

Effective July 1, 2008, the sewer service charges will be billed thru the county's property tax bill.

Customers' sewer charges are based on their January and February water consumption.  These two months fall during our rainy season; hence, water used during this period is normally used for indoor use only and not for landscaping, etc.  The sewer service charge is adjusted annually on July 1st of each year.

New customers' sewer charges are based on the current assessment until they have established their own consumption during the base period of January and February.  The sewer service charge is then adjusted annually on July 1st of each year.

The meter service charge for residential customers is currently: $20.00 (for 5/8" meters) and $26.55 (for 3/4" meters) per bimonthly period.  Please see chart below for the bi-monthly meter service charges for all other meter sizes.

of the billing date, an additional 5% of the past-due amount or a minimum charge of $5.00, whichever is greater.

Shut Off Notice Fee (previously Door Collection Fee):  A $30.00 charge will be added to the amount due once a notice for shutoff has been issued for non-payment.

Reconnection Charges:  Charges to have water turned back on are $50.00 during regular business hours and $115.00 after office hours (this includes weekends and holidays).  It is unlawful for anyone other than Westborough Water District personnel to turn the water on.  Violation will result in meter removal and a $50.00 fee.

Currently, bills may be paid:

  • In person at the District Office, 2263 Westborough Blvd., South San Francisco during the hours of 8:00 a.m. to 4:30 p.m. (cash, checks, money orders, Visa, and MasterCard)

The Westborough Water District is being required to make improvements to our parking lot to add a handicap parking space which will reduce the number of customer parking spaces from five to two spaces.  With limited parking, we urge customers to sign-up for automatic payment deductions or use the Districtís drive-up drop box, preferably during non-working hours.  Our parking lot tends to get really full on the due date of the bills and it will become even more challenging after the improvements are made.  So, please note that if your payment is placed in the drop box on the due date, it will be considered timely received as long as it is in the box by the time we open the office at 8 a.m., the following business day. 

  • After-hours in our convenient 24-hour payment drop off box located near the garage at the District Office.  Please do not drop off cash in this box.
  • By mail:  Westborough Water District, P.O. Box 2747, South San Francisco, CA 94083-2747 (checks or money orders)

  • Online Payments: Make a one-time payment or sign up for reoccurring payments using your Visa, MasterCard, or personal check on our secured website: Click here to access Online Payments.
  • By using your own bankís automatic payment withdrawal service.  Since your bank will mail us a check, please make sure to allow at least 7 to 10 business days for posting.
