Service areas
We cover the West Puget Sound metros and the rural areas around them, where private septic systems and transfer inspections are most common. Each city page carries its county specifics, starting with the Thurston County lane around Olympia and Lacey.
The county matters more than the city here, because the rule that drives most septic calls, the inspection tied to a property changing hands, is written county by county. Each city page below names its county office, cites the rule that applies, and covers what the required work costs where published figures exist.
Thurston County
Time of Transfer Evaluation Report required before a septic-served property sells or transfers, in effect since September 1, 2010, per the county fact sheet (PDF). Administered by Thurston County Environmental Health in Olympia.
Kitsap County
Property conveyance inspection before the final sale of septic-served property under Board Ordinance 2025A-01, effective March 17, 2025. Administered countywide by the Kitsap Public Health District in Bremerton.
- Bremerton
The conveyance inspection step by step, from the city where the district is headquartered.
- Silverdale
Unincorporated Kitsap, where the health district is the only septic authority there is.
- Port Orchard
The county seat and the South Kitsap septic country around it, on the district's countywide process.
Mason County
No county transfer mandate today; instead, operation and maintenance reports filed with the county under code Chapter 6.76, per Mason County Environmental Health. Those records surface when a home sells.
- Shelton
The records program, the Hood Canal rebate, and what the 2027 statewide rule changes.

What it costs, and what happens after you send it
- What does septic work cost in the West Sound?
- It depends on which job, so here they are separately. Clean Septic Pumping lists $175 for a gravity system or $225 for a pressure system, plus $85 if pumping is not done on the same visit (a contractor-published price list serving Thurston County). For pumping, the same published lists show $535 for a pump-out, with Premier Septic Services in Yelm publishing $600 for tanks to 1,200 gallons, and a county pump report fee of $25 in Thurston County or $65 in Pierce County sits on top of that, and it is the county’s charge rather than the contractor’s price. Sterling Septic and Plumbing (a Puyallup contractor publishing its own replacement guide) puts $1,000 to $5,000 and beyond for extensive repairs such as tank replacement or drainfield restoration, and roughly $5,000 to $7,000 and up for a conventional gravity system, with a full installation able to pass $15,000. Where a real quote lands is decided by the system type, the soil and water table, access for a truck or an excavator, and whether the design has to move from gravity to pressure. A pressure or mound system sits well above a conventional gravity one. The Washington time-of-sale guide sets the published figures out in one table.
- How fast will someone get back to me?
- Your request goes to an independent local septic contractor, usually within about an hour during the day. That contractor then contacts you to look at the system and price the work on their own schedule.
- What work is covered?
- Septic installation, septic repair, septic pumping, septic inspection, time-of-sale inspection, and operation and maintenance. See every service.
Only a contractor standing at your tank and drainfield can price your actual system.
