Use the Correct Hayward Water or Sewer Provider Before You Pay

Most Hayward properties use City-provided water and sewer, but some addresses use East Bay Municipal Utility District for water or Oro Loma Sanitary District for sewer. The provider name on the bill decides which payment system and customer-service number to use.

Hayward Water System

Use the City payment options and Water Customer Portal when the bill is from Hayward Water System.

Residential nonpayment timeline

Hayward Water Late Fees, Shutoff Notices and Payment Arrangements

The City’s residential policy uses specific notice stages. If you already have a shutoff notice, the City water-support page lists 510-583-4624 for the billing office.

15 DAYS Bill becomes delinquent

The policy says utility bills are delinquent 15 days after the billing date.

35 DAYS $5 late fee

If still unpaid 35 days after the bill date, a $5 late fee and Late Payment Notice are issued.

21 DAYS Final contact stage

If unpaid 21 days after the Late Payment Notice, the City attempts phone contact or hand-delivers a Final Notice.

7 DAYS Possible shutoff

The Final Notice requires payment within 7 days before service may be discontinued.

Arrangement options After a Late Payment Notice, the owner may request an arrangement, deferment, reduced payment or alternative schedule. The normal policy aims for repayment within 12 months.
Medical and financial protections Additional shutoff protections can apply when the policy’s medical-risk, financial-hardship and payment-arrangement conditions are met.
Call before shutoff For options to avert discontinuation, call 510-583-4600. The policy lists Mon-Thu 8 a.m.-6 p.m. and Fri 8 a.m.-noon for these discussions.
Reactivation fee warning: Current City sources show different activation, restoration and nonpayment-reconnection figures. Call 510-583-4600 and ask for the exact amount due on your account before paying for restoration.
Payment help and bill disputes

Payment Assistance, Low-Income Discounts and Bill Disputes

Payment arrangement Contact Revenue at 510-583-4600 or HSS@hayward-ca.gov as soon as possible if you are behind.
Low-income discount The City has a program with discounts and waivers for certain garbage, water and sewer rates.
Accuracy dispute A written request to review utility-bill accuracy must be submitted no later than 30 days from the original bill date.
Scope of a dispute: The review is for the accuracy of charges. It is not the process for challenging the general rate level, pending rate changes, water source or similar policy matters.

Review the official nonpayment and dispute policy or open the low-income discount application page.

How to Start or Stop Hayward Water and Sewer Service

Request Current guidance What matters
Start service Submit the application or contact Revenue before the requested start date The current application says at least 2 business days; the service webpage says at least 1. Planning 2 business days ahead is safer.
Stop service Contact the City at least 2 business days or 48 hours ahead Provide name, account number, forwarding address, phone and requested stop date. Closures cannot be backdated.
New residential account The 2026 application lists an $87 establishment fee and $70 residential deposit The customer-service page describes deposits as applicable, so confirm whether the deposit applies to your account.
Same-day activation An additional activation fee applies The service page and FY2027 fee schedule show different figures. Confirm the current fee before requesting same-day or after-hours work.
Moving out does not automatically close the account. The person who opened the account remains responsible until the City is contacted to stop service or a new party establishes service.

Usage and meter troubleshooting

Why a Hayward Water Bill Is High and How to Check the Meter

Compare the same billing period. Hayward bills are bimonthly, so compare service dates and CCF rather than only the dollar total.
Convert CCF when useful. One CCF equals 748 gallons.
Turn off indoor and outdoor water. Check the meter’s Flow Finder and Test Circle. Movement while everything is off may indicate a leak.
Check customer-side plumbing. Inspect toilets, irrigation, hose bibs and buried lines. Customers maintain leaks and damaged pipes on their side of the meter.
Use WaterSmart hourly data. Continuous or overnight use can help narrow down when a leak or unusual consumption occurs.
Call Revenue if the bill still looks wrong. Keep the bill date, account number, meter reading, usage notes and repair records available. A formal accuracy dispute has a 30-day deadline.
Who repairs what? The City maintains the meter and facilities on the street side. The customer maintains pipes and leaks on the customer side.

Common Hayward Water Bill Mistakes to Avoid

Mistake Why it matters Better action
Using a generic search result as the payment page Search can surface ads, unrelated processors or outdated links. Start from Hayward WaterSmart or the City’s payment page.
Assuming every Hayward address has the same provider Some addresses use EBMUD water or Oro Loma sewer. Check the provider printed on the bill.
Treating the bill as monthly Most City bills are bimonthly. Compare service dates and CCF usage.
Expecting a routine online card fee The City’s current page lists accepted online methods as fee-free. Review the live checkout screen, not an old article.
Mailing payment after a shutoff notice Mail may be too slow and the City specifically advises against it in that situation. Contact the billing office and use an immediate approved payment route.
Using Access Hayward for a sewer overflow The City says this delays response. Call 510-881-7967 during the weekday window or 510-293-7000 after hours.
