A backwater device is installed on the customer's sewer lateral connection to the sanitary sewer system. This sewer lateral connection is the pipe that connects the customer's property to the City sewer main. The device must be installed downstream of any drains or openings to the sewer lateral connection. During a sewer backup, the backwater valve is designed to close and prevent water from backing up into the property.
The device is designed to protect the property during heavy rains, but a backwater device will not solve other sewer lateral issues such as roots, cracks, or broken pipes. It also will not solve basement integrity issues such as cracks in walls, floors, or window well leakage.
The application process involves meeting the eligibility requirements and submitting an application that provides information regarding the property applying to participate.
- The application is submitted to the Department of Public Works and Public Utilities, and a City representative contacts the customer to confirm eligibility.
- Two licensed plumbers of the customer's choosing will inspect the property and provide a cost estimate for installing a backwater valve if a backwater valve is not present.
- If the plumbing inspection reveals a backwater valve is present at the property, corrective action may be taken to repair the existing valve if it is properly installed.
- The customer submits the estimates to the City and confirms that the proposed work will meet the program's intent. The customer may select the contractor of their choice, but the reimbursement will be for the lowest dollar amount of the comparable estimate submitted.
- The licensed plumber performing the installation of the backwater valve is required to obtain a plumbing permit from the City of Garden City Department of Neighborhood and Development Services.
- The installation is inspected for proper installation by the City inspector and verification of work completed.
- The customer provides the paid receipt for the work completed, and a reimbursement payment is processed by the City.
