How to Establish Residential Water Service

Prior to establishing your home site, we encourage you to contact TOUA Water Department to evaluate if your home can be served properly with water and wastewater services.

Residents who would like to set up new service with TOUA on property assigned to them must be 18 years old, and proof of age must be verified with identification such as a driver’s license, tribal identification, or a social security card. Applicant must also submit a district resolution that gives TOUA permission to provide ALL utility services. A service deposit may be required. If you are requesting water service on land that is assigned to someone else, you will need to submit a notarized letter from the named land assignee that gives you permission to establish utility services with TOUA. A signed contract and deposit fee must be paid before the service is supplied.

Plumbing Services From TOUA

TOUA offers limited plumbing services to help you fix drips, leaks, and clogged drains. While TOUA maintains water lines to the water meter, the homeowner is responsible for fixing any issues from the water meter to the home. To assist our customers, we offer plumbing services at reasonable rates billed by the half-hour. Plumbing repair costs include labor, materials, and service charge:
If a plumber responds to your home for consultation only a $40 fee applies plus service charge. Consultation consists of evaluations and recommendations for repairs.
