Rules and Restrictions on Professional Residential Sewer Line Installations in Snohomish County

Installing residential sewer lines in Snohomish County involves adhering to specific regulations to ensure public health and safety, environmental protection, and infrastructure integrity. Whether constructing a new home or upgrading an existing system, understanding the requirements is essential for homeowners and contractors involved in such projects.

Sewer Solutions NW, as a trusted provider of sewer repair services in Snohomish County, WA, discusses the rules and restrictions on sewer line installations in the area.

Permit Requirements

Before initiating any sewer line installation, obtaining the necessary permits is mandatory. The Snohomish County Planning and Development Services (PDS) department oversees the permitting process for work within public rights-of-way and for utility installations. This includes securing a Right-of-Way Use Permit if the installation affects public roads or spaces. For detailed information on permitting, visit the PDS Permitting page.

Design and Construction Standards

All new sewer lines installed in public rights-of-way must conform to the city's adopted standards and specifications.¹ This guarantees consistency, safety, and reliability across the county’s sewer infrastructure. Specific requirements, such as minimum utility line sizes, are outlined in the Snohomish Municipal Code.

Connection Requirements

Within Urban Growth Areas (UGAs), connecting new structures to a public sewer system is typically required as a condition for the issuance of building permits.² Exceptions to this rule are specified in the Snohomish County Code (30.29.100).

Professional Licensing

Sewer line work must be performed by professionals licensed in accordance with Washington State regulations. This ensures that any sewer line replacement or installation job meets the required standards and is executed by qualified individuals. Homeowners are advised to verify the credentials of any contractors they hire.

Inspections

Penalties for Unauthorized Connections

It's important to note that making or maintaining any connection with a sewer system without permission from the district is unlawful and classified as a misdemeanor under Washington state law. Unauthorized connections can lead to legal penalties and pose risks to public health and the environment.
