Importance of Proper Septic-to-Sewer Conversion

Switching from a failed septic system to a public sewer connection is a major upgrade — but only when done right. An improper tie-in can lead to property damage, code violations, and costly rework. At Lilly’s Septic Service, we handle the entire conversion process with precision, ensuring your old septic system is safely decommissioned and your new sewer connection is built to last.

Our licensed installers follow all King and Pierce County regulations, protect your property from unnecessary excavation, and ensure every step — from permits to inspection — is completed correctly the first time.
