Rates & Billing

  • 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 are no longer billed bi-monthly. Instead, the sewer service charges are billed through the county's property tax bill.

Water Charge

Effective July 1, 2018

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.


Sewer Charge

Effective July 1, 2018

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 City’s 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 are billed through the county's property tax bill.


Calculation of Sewer Charges

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

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.


Meter Service Charge

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.

Meter Size Current Rate
5/8" $20.00
