NJ has the Low Income Household Water Assistance Program (LIHWAP) running through the same offices as LIHEAP. My aunt in Camden cleared $580 in water arrears last summer. Covers drinking water and sewer. Upload last two bills, lease if tenant, and pay stubs. The site has a water-only application tab: [https://www.utilityassistance.org/nj/](https://www.utilityassistance.org/nj/) – approval in 10-14 days, payment direct to utility. They even back-date to prevent shut-off.
