Payment research for this provider
The compiled notes distinguish confirmed channels from details the public material did not expose. Fields containing only an unavailable-information marker are grouped in the research record below.
- Payment platform
- MyCPAU; the reviewed official pages do not identify the underlying portal vendor.
- Phone payment number
- (650) 329-2497 for the automated 24-hour payment and balance system. Customer Service is (650) 329-2161.
- Pay-by-text
- MyCPAU supports customized notification preferences and WaterSmart leak alerts, but the reviewed payment pages do not publish a text-to-pay keyword or short code. Customers should enroll in MyCPAU notifications and use the portal or automated phone system for payment.
- Mail-in payment address

Credit/debit card payments are handled at the Utilities counter with tap-to-pay; cash/check payments go to the Revenue Collections Counter. Night depository boxes are available at City Hall and the Civic Center Garage.
- Digital payment methods
- MyCPAU supports credit/debit card and checking-account payments, including recurring AutoPay and free automatic bank drafting. The reviewed pages do not verify ACH fee details beyond free bank drafting or digital wallets.
- Online convenience fees
- Recurring credit-card payments are advertised with no service fee. Rule and Regulation 11 permits a cost-recovery fee of up to 2.7% on amounts over $5,000 for certain card payments; the reviewed pages do not expose a standard residential 2026 online fee below that threshold.
