Leak relief and household assistance

A high water bill may have a path to review

Hidden plumbing failures can produce an alarming bill before the problem is visible. This guide separates what Washington Suburban Sanitary Commission (WSSC Water) publicly describes from the practical steps every customer can take while requesting help.

Provider-specific review

What the public record says about a leak adjustment

WSSC treats private-property plumbing maintenance as the customer’s responsibility but provides several adjustment paths. A single-unit residential customer with a high bill caused by an unidentified condition may qualify when Average Daily Consumption is at least three times the comparable seasonal ADC from the previous year, or the current ADC when no comparable history exists; this specific high-bill adjustment does not require a plumber invoice or permit. Customers should email an adjustment request with the account number or service address, adjustment type, leak description, repair dates, repairer, and affected billing periods. Inside-meter customers must provide two check readings at least 10 days apart; WSSC obtains readings for outside meters. Underground water-line work must be performed by a registered licensed WSSC plumber where required, and customers should retain invoices, permits, photos, and proof the repair is complete. CAP customers may qualify for removal of 100% of excess water and sewer usage for up to two consecutive billing periods once in a three-year period. The utility also provides a CAP Leak Repair Program with Habitat for Humanity Metro Maryland; the current FY27 budget materials describe up to $9,000 per year in eligible leak-repair services. Meter-test fees are credited if a certified test finds the meter over-registered.

Utility assistance

Customer assistance and eligibility

WSSC’s Customer Assistance Program is linked to the Maryland Office of Home Energy Programs (OHEP): a customer applies through OHEP at https://dhs.maryland.gov/office-of-home-energy-programs/ or 800-332-6347, and WSSC receives the eligibility notification. Current FY27 guidance states CAP provides up to $319 per year in credits for WSSC water/sewer fees, including the State Bay Restoration Fund fee; it does not erase usage charges. CAP customers are permanently exempt from late fees and automatically receive the BRF exemption. The WSSC Water Fund provides multiple emergency or one-time bill-assistance requests up to $500 in a rolling 12-month period. Promise offers interest-free flexible payment plans, and CAP customers may also qualify for the CAP Leak Repair Program. Income, customer-name, ID, and program-specific documentation requirements apply.

State and federal connections

Where to ask for broader aid

WSSC integrates state assistance through Maryland OHEP, which determines CAP eligibility and can also provide energy-assistance benefits; the customer applies through the Maryland DHS/OHEP portal and WSSC applies the corresponding utility credits after notification. CAP includes the state Bay Restoration Fund exemption. WSSC separately directs customers to county assistance resources in Montgomery and Prince George’s counties and to Maryland/community organizations, while Promise handles flexible plans. The WSSC Water Fund is locally funded and administered through a third party, with current assistance capped at $500 in a rolling year. Customers should confirm any state or federal grant round through Maryland DHS/OHEP and ask WSSC to identify the account before an agency payment is sent; WSSC’s current pages do not advertise an open standalone LIHWAP water grant.

Leak and assistance notes

Build the file before asking Washington Suburban Sanitary Commission (WSSC Water) for relief

A high bill can have several causes, including a hidden plumbing failure, irrigation use, a meter issue, a change in occupancy, or a rate adjustment. The provider’s leak policy determines whether any credit is available; an unusually high bill does not automatically qualify.

Keep a dated record of the reading, the suspected source, the repair, the contractor or parts receipt, and the return to normal use. Ask whether the utility requires a specific form, a licensed repair, a meter test, photos, or a request within a fixed number of days.

For income-related difficulty, ask about local assistance, payment arrangements, state programs, and community referrals separately from a leak adjustment. These programs often use different applications, documents, funding limits, and deadlines.
