San Francisco Water Power Sewer

Quick overview

The San Francisco Public Utilities Commission (SFPUC) runs utility support for residents who struggle with monthly household bills. The current core program is the Customer Assistance Program (CAP), not a one-off grant portal. CAP covers:

1. Water and sewer CAP (SFPUC water/wastewater customers)
2. Hetch Hetchy Power CAP (SFPUC electric customers)

If your household has low income and a qualifying account structure, this opportunity may lower utility bills for up to 36 months at a time.

CAP is not a simple rebate that works once. It is a recurring discount program with renewal requirements and change-of-income rules. The details differ by utility service, so the first decision is which CAP track is relevant to your bill.

At-a-glance

The above reflects current SFPUC pages and FAQ wording as of the last official check.

What this opportunity is (and what it is not)

This is not a generic “energy assistance” program. It is specifically SFPUC CAP and is tied to your SFPUC account for water, wastewater, or Hetch Hetchy Power.

Not supported claims to avoid:

• No blanket “emergency grant up to $500” is presented as a general, current CAP feature on the main SFPUC CAP pages.
• Older references to a separate SuperCAP label are not part of the current confirmed official CAP pages for this service.
• There is a distinct Emergency Residential Customer Assistance Program in SFPUC history, but that listing is marked as ended on SFPUC’s site.

What is supported today:

• CAP discounts on water/wastewater and on Hetch Hetchy Power,
• a separate Hetch Hetchy Power Medical Necessity Assistance Program for certain medical-access cases,
• a separate Extenuating Circumstances route for temporary shutoff/lien prevention.

Who this is for

CAP is designed for households that can fit into SFPUC’s income and account rules.

You are likely a strong fit if you:

• live in San Francisco and currently owe/receive SFPUC water, wastewater, or Hetch Hetchy Power bills,
• have one qualifying account in your own name,
• have household income under the published CAP thresholds,
• are willing to provide or authorize household income verification,
• can respond quickly if SFPUC asks for follow-up proof.

You are not likely a fit if you:

• do not have a qualifying SFPUC account in your name,
• have an account type that SFPUC explicitly excludes,
• have moved into complex shared or commercial-style billing structures,
• cannot keep household income details current and conflict-free.

For water/wastewater, one of the key filters is that the account needs to be a residential, individually metered single-family account (that is, one water and wastewater account tied to the dwelling and in the customer’s name).

Who can apply: water/wastewater CAP vs power CAP

Water and wastewater CAP

You may qualify if you are a SFPUC water/wastewater customer and have one qualifying account, residence in SF, and qualifying income. SFPUC lists these points in the official water/wastewater CAP criteria:

• one water and wastewater service account,
• bill in your name,
• full-time resident at that address,
• not claimed as someone else’s tax dependent,
• single-family account that is individually metered.

It is not only a “low income only” threshold question. SFPUC also defines who is in your household for income testing. All persons living in the same dwelling served by the same SFPUC account count. This includes roommates and extended household relationships, not just immediate family.

Hetch Hetchy Power CAP

For Hetch Hetchy Power CAP, criteria include:

• one Hetch Hetchy Power service account,
• the bill is in your name,
• full-time resident at the service address,
• not claimed as another person’s tax dependent,
• combined household gross income at or below CAP income guideline levels (SFPUC-published table, updated with Federal Poverty Guidelines).

The Hetch Hetchy page indicates a major procedural difference: proof of income is not required at the moment you apply. But SFPUC may verify income later through audits or requests, and non-compliance then can end participation and require payback.

Eligibility criteria in practical terms

CAP has rules that look similar across services but with different income mechanisms.

Household income rules

Both pages define household income broadly as gross income from all people in the household, including income from wages, pensions, unemployment, self-employment, benefits, support income, and other income sources. The practical implication is:

• You should include everyone who truly lives in the SFPUC account household,
• you should avoid leaving out roommates or family members who receive shelter at the same address,
• if income changes substantially, update SFPUC quickly.

Account and residency rules

• Your name should be on the account.
• You should be a full-time resident at the service address.
• Tenancy is not automatically disqualifying if you are account holder. If the landlord is account holder and your utilities are embedded in rent, the CAP discount may not directly apply to the landlord account.

Account type (water/wastewater)

Water/wastewater CAP excludes some account categories, including certain nonresidential and group/irrigation forms. The SFPUC page explicitly says the following types are not eligible:

• fire service,
• residential multiple,
• irrigation,
• commercial,
• wholesale.

Income verification methods

How SFPUC verifies income differs by service and chosen path.

Water/wastewater CAP

Verification is done at application time through one of:

• TransUnion (online path), using names and birthdates for all income earners, or
• SFHSA authorization path for households on CALWORKS, CALFRESH, or MEDI-CAL, which uses prior city data.

If SFPUC cannot verify your income, they contact you for more information.

Hetch Hetchy Power CAP

SFPUC states that proof is not required at application time, but this is based on a customer certification and the right of SFPUC to request proof later.

How to apply: practical step-by-step

Think of this as a file prep and submission process, not a single click.

1) Decide your track first

Go to the right page for your bill:

• Water/Wastewater CAP
• Hetch Hetchy Power CAP

If your hardship is temporary and your income is between 51% and 80% AMI, or you have a recent hardship event with risk of shutoff/lien, also review Extenuating Circumstances.

2) Prepare required materials before applying

Prepare identity and income details for everyone in the household who appears on the account, even if not in immediate family.

For water/wastewater CAP, SFPUC expects income documentation or verification setup:

• For online submission: names and dates of birth for all income earners for TransUnion.
• For paper + HSA route: details for SFHSA benefits (if applicable).
• For manual submission paths: commonly accepted documents include paycheck stubs, SS/SSI checks, W-2s, social security verification letters, or unemployment statements.

For Hetch Hetchy Power CAP, you may submit even when not attaching proof immediately, but keep all income documentation ready for follow-up audits.

3) Submit through a supported channel

SFPUC gives several channels:

• online application,
• printed application by phone,
• in-person at Customer Service Counter at 525 Golden Gate Avenue, San Francisco, 1st Floor,
• mail route where a paper application is accepted.

Phone options listed by service:

• Water/wastewater customer service: (415) 551-3000, Monday to Friday 8 a.m.–5 p.m., except holidays,
• Hetch Hetchy Power customer service: (415) 551-4720, Monday to Friday 8 a.m.–5 p.m., except holidays.

4) Track processing and decision

• Water/wastewater applications: SFPUC states around 3–4 weeks processing, with discount on the first full billing cycle after approval.
• Hetch Hetchy Power applications: about 2–3 weeks typical after submittal, with discount starting on first full approved billing cycle.
• SFPUC will notify by email or mail with approval/denial.

5) After approval

Discounts apply regularly on monthly bills while valid. If renewal is needed, you must complete reapplication to avoid expiration.

Income comparison and why planning matters

Most applicants lose value when they do the rough math too late. A practical way to decide is this:

1. Pull your last 12 months of household income from all members.
2. Confirm household size based on SFPUC’s account-defined household.
3. Compare against published CAP thresholds.
4. Add up expected monthly savings using your actual bill baseline.

For water/wastewater, the published 2025 AMI thresholds are split:

• up to 50% AMI gets 25% discount,
• up to 30% AMI gets 40% discount.

For Hetch Hetchy Power, 2025 Federal Poverty Guideline references are used on SFPUC’s table.

Whether you qualify is often obvious once you complete this one-page check before spending a day gathering forms.

What it offers and what to expect financially

CAP is usually best understood as a combination of:

• Monthly bill reduction in fixed utility categories,
• lower risk of account actions when participation is active,
• a structured timeline for renewals instead of ad hoc emergency promises,
• optional pathways for hardship events beyond standard income-based CAP.

Water/wastewater-specific practical value

The most common value for households is predictable monthly relief across water and sewer charges where budgets are tight.

Because these bills can be high in an urban context with variable usage, a 25% or 40% reduction can materially change whether monthly essentials can be paid.

Hetch Hetchy Power-specific practical value

The 30% discount can reduce recurring energy expenses, especially where low income is coupled with older appliances or high household electricity needs.

Secondary but useful benefit

SFPUC also points customers to related bill relief and conservation resources, including water-saving and efficiency resources. While those are separate programs, they work well with CAP if you are trying to stabilize a fragile household budget.

Timeline and deadlines

CAP on these pages is not tied to a single annual application window. That means there is no fixed “open until” date like seasonal aid programs.

What is time-sensitive is your bill status and verification timing:

• If you have not been approved, discounts do not apply retroactively unless SFPUC says otherwise.
• If denied, water/wastewater pages note a 3-month wait before submitting a new paper application and recommend complete income documentation.
• If you are already approved and your income rises or household composition changes, report changes promptly.

Practical rule of thumb: treat approval lead times as at least three weeks and plan a buffer before a financial crunch month.

Required materials checklist (by channel)

Water/wastewater channel

• SFPUC account number and current billing name
• Full household list and income details
• For online verification: full names and DOB for all income earners (TransUnion path)
• For paper/HSA path: required info for eligibility verification and supporting benefit documents when applicable
• Passport/ID documents and proof of occupancy if requested

Hetch Hetchy Power channel

• SFPUC account details
• Household composition details and income declarations
• Contact/notice details (email is useful for status updates)
• A plan to respond quickly if SFPUC requests proof

Commonly accepted proof documents in SFPUC guidance

• 2 consecutive paycheck stubs,
• 2 consecutive Social Security/SSI checks,
• W-2,
• Social Security benefit statement,
• unemployment statement.

Keep these as clear copies to avoid repeated correspondence rounds.

Readiness tips before hitting submit

Build a file before opening the form

• Gather all names and DOBs for people in the household at the service address.
• Identify the single account-holder name exactly as shown on the bill.
• Pull all recent utility notices and payment history.

Use a verification-first filing strategy

For water/wastewater CAP, if you can verify via online TransUnion and have complete DOB data, that path is generally cleaner than paper. If you are on SFHSA benefits, review the HSA authorization option.

Avoid common cause of denial

The number one avoidable denial cause is missing or inconsistent household information.

If you apply for both tracks

Some households carry both utility bill types with SFPUC. If possible, keep each filing separate and do not mix accounts. CAP is account-specific.

Common mistakes

1. Applying under the wrong CAP page for the bill Water account applicants should not submit only Hetch Hetchy Power CAP details.

2. Assuming denial is final Water/wastewater guidance states appeals/review requests are available and can be done with complete documentation.

3. Ignoring income changes If income rises or household members leave/join, participation can change. Not reporting changes can cause later repayment.

4. Using a landlord-led account without matching billing status Tenants often need account holder alignment; CAP may not appear on tenant-paid-through-rent accounts.

5. Waiting until disconnection notices arrive CAP should be started as prevention, not as post-termination crisis paperwork.

6. Treating CAP as one-time emergency money It is a recurring discount with required recertification.

What to do if your application is denied

For water/wastewater CAP, official guidance says denial letters include reason and review options, and says a denied household should reapply with complete documentation after a waiting period.

For Hetch Hetchy Power CAP, applications can also be denied when income criteria are not met or documentation/certification is incomplete. In both cases, prepare a clean second submission package.

How to decide if it is worth your time

Use this practical readiness test:

• You have a qualifying SFPUC account in your name,
• your household income is likely in threshold range,
• expected discount is high enough relative to monthly bill and paperwork burden,
• you can monitor email/mail for SFPUC requests,
• you can either complete online verification or return requested documents quickly.

If most answers are no, CAP may still be available but not the best first move. Consider alternatives first, such as payment plans, extenuating circumstances, or utility-specific medical necessity pathways.

Related SFPUC options to check after CAP

Hetch Hetchy Power Medical Necessity Assistance Program

If your eligibility is tied to medical devices or serious conditions, this is a separate program. It can grant additional room to use electricity (allowing up to 75% more energy at the general residential service rate according to SFPUC) and requires:

• physician/surgeon certification,
• device or condition documentation,
• mailed application,
• up to 4–6 weeks processing,
• annual reapplication unless permanent disability is demonstrated.

Extenuating Circumstances (shutoff/lien prevention)

Useful when income is between 51% and 80% AMI and you can document a recent hardship event (job loss, medical bills, death, disability, or similar) within one year.

If approved, this is temporary (up to 6 months, with a possible extension, up to 12 months total).

Payment plans and debt support

SFPUC directs customers to contact Customer Services when behind on bills. For many households, payment plans reduce risk while CAP is being reviewed.

Frequently asked questions

Is there a filing deadline?

No fixed calendar deadline is currently advertised for CAP start dates. You can apply while eligible. The practical urgency is the next billing cycle and any delinquency action.

How long until relief starts?

For water/wastewater, around 3–4 weeks after submitted application, then starts from the first full cycle after approval. For Hetch Hetchy Power, SFPUC notes about 2–3 weeks then next full cycle after approval.

Do I need to send income proof with my first power CAP application?

Not always at first submission. But you should be prepared for follow-up proof requests.

How often do I need to reapply?

SFPUC states CAP discounts are generally structured for 36 months and require reapplication/renewal.

Will CAP help with shutoff notices?

CAP can help protect households on eligible accounts, and SFPUC mentions shutoff and lien protections tied to CAP participation. For water and sewer emergencies, separate extenuating-circumstances routes are also available.

Can my household with roommates apply?

Only if all household members are properly included in the income count and account definitions. Household definition is broad and includes non-family residents sharing the unit.

Can tenants apply?

Yes when the tenant is the named account holder. If utilities are billed through landlord/other account, CAP may not directly apply.
