Sewer Standby
A sewer standby charge may apply to qualifying properties where sewer service is available but the property is not receiving full sewer service.

Larger Residential Meters
Residential customers with meter sizes larger than 5/8 inch may have different monthly rates.
Please contact the District for the rate applicable to your meter size and service.
Commercial & Institutional Rates
Commercial and institutional monthly service charges are generally based on the size of the meter serving the property.

| Service | Additional Usage Rate |
|---|---|
| Water | $5.70 per additional 100 cubic feet |

Commercial and institutional properties with unusually high water demand, high-strength wastewater, or other special service requirements may be subject to different or additional charges.
Please contact the District for current commercial, institutional, and larger-meter rates.
Taxes
The residential monthly rates listed above include the applicable 5% utility tax.
Please contact the District with questions about taxes applicable to commercial, institutional, connection, assessment, inspection, or other charges.
Residential Connection Fees
Connection fees are one-time charges associated with establishing a new connection to the District’s sewer or water system.
| Connection | Fee |
|---|---|
| Sewer Connection | $6,000.00 |
| Water Connection | $6,000.00 |
Standard residential connection charges are based on one Equivalent Residential Unit (ERU).
Connection fees help fund a property's share of District infrastructure and system capacity, including sewer collection lines, pumping stations, wastewater treatment facilities, wells, reservoirs, water mains, and major system improvements.
Different or additional connection charges may apply when a property has special service requirements, including increased fire-flow needs, unusually high water demand, high-strength wastewater, or multiple Equivalent Residential Units.
Assessments
Some properties may be subject to District assessments associated with infrastructure, system improvements, or services benefiting a particular property or service area.
Assessments are separate from regular monthly sewer and water service charges and may vary by property.
If an assessment applies to your property, please contact the District for information about the assessment, current balance, and applicable payment requirements.
Inspection Fees
Inspection fees may apply as part of establishing a new sewer or water connection.
| Inspection | Fee |
|---|---|
| Sewer Inspection | $150.00 |
| Water Inspection | $150.00 |
Applicable inspection fees are due as part of the new-service connection process.
Commercial, Multi-Unit & Larger-Meter Connections
Commercial, institutional, multi-unit, and larger-meter services may have different connection fees and requirements.
Applicable charges may depend on factors such as meter size, water demand, fire-flow requirements, wastewater characteristics, number of Equivalent Residential Units, and property or development type.
Please contact the District for rates and fees applicable to your specific property or project.
New Sewer or Water Connections
New sewer or water connections may require District approval, applicable connection and inspection fees, and completion of a Standard Participation Contract and other required documents.
Governing Code
District rates, fees, assessments, service requirements, and other utility matters are subject to applicable District policies and the Lummi Nation Code of Laws, Title 16 – Sewer and Water District Code.
