Septic-to-Sewer Conversion for Reliable Sewer Connections

Converting from a septic system to a municipal sewer connection can improve reliability and reduce long-term maintenance concerns. Seattle Select Sewers provides professional septic-to-sewer conversion services to help homeowners transition from private septic systems to city sewer infrastructure.

Transition from Septic to a Municipal Sewer System

Some properties originally built with septic systems may later gain access to a municipal sewer connection. Converting from septic to sewer allows wastewater to flow directly into the public sewer system rather than being processed through a private septic tank and drain field. For many homeowners, this transition can simplify wastewater management and reduce the need for septic system maintenance.

What We Do

Septic-to-Sewer Conversion Services We Provide

Converting a property from septic to sewer involves multiple steps, including disconnecting the existing septic system and installing a new sewer line connection. Our team evaluates the property layout and local sewer access points to ensure the conversion is completed safely and efficiently.

Sewer Line Connection Installation

We install a new sewer line that connects the property’s plumbing system to the municipal sewer main.

Septic System Decommissioning

When converting to sewer service, the existing septic system is properly disconnected and decommissioned according to local guidelines.

Sewer Line Routing and Installation

New sewer lines are installed underground to safely transport wastewater from the home to the public sewer system.

Sewer System Integration

After installation, the plumbing system is connected to the new sewer line to ensure proper drainage and functionality.
