Septic Tank Locating and Risers in Snohomish County, WA
A buried lid is a common reason a pumping or inspection visit takes longer than it should. If you cannot find the tank, or if every visit starts with a shovel, a septic professional can locate it and, where it suits the tank, fit a riser that brings the lid up to the surface. This site is a referral service. Your request goes to a provider, who gets in touch about it and does the work. Never open or enter a septic tank yourself. Tanks contain toxic gases.
When you might need it
When you cannot find the tank, when the lid is buried and every pumping or inspection visit needs digging, or when you want a riser fitted so later service is simpler.
What is included
- Locating the tank, starting with the record drawing and county or OnlineRME records where they exist, then a site visit if the lid is still not found.
- Exposing a buried lid, where digging is needed, with that work agreed before the visit when possible.
- Riser installation, where it suits the tank, so later pumping and inspections can reach the lid without another dig.
Pricing guidance
Guidance only, never a quote. A riser, as a component example in local cost guides used on this site, typically runs $300–$600 (Western Washington Septic System Guide, as listed on the Snohomish County costs page). Locating and digging prices depend on the site. This page does not publish a separate locating figure. Pumping typically runs $650–$1,000, and the price often depends on whether a lid needs digging up. A $50 Savvy Septic rebate may be available per riser, up to two risers, where eligible. Only the provider can confirm a price for your property.
Start with the drawing and the service record
If you have a record drawing (as-built) for the system, start there. A property-transfer inspection or a previous pumping visit may already have described the lid locations, and Snohomish County tracks service history through OnlineRME. If you do not have a drawing, ask the Snohomish County Health Department, or your title company, whether a copy exists for the property. Mark anything you already know in the yard, and clear vehicles and stored items off the tank and drainfield before a provider arrives. If you are not sure whether the home is on septic or sewer, our guide Is my Snohomish County home on sewer or septic? explains how to check. That paperwork step is often enough to point to the right patch of yard. When it is not, the visit is what finds the lid.
When locating is its own job, not just part of pumping
A pumping visit in this county typically starts with finding and opening the tank, and buried lids need digging up first. The less time spent locating lids, the less the visit costs in time, which is why marking the location once you know it is worth doing. Use this page when the tank cannot be found, when you want locating done before a pumping or routine inspection, or when you want a riser as a job in its own right. In the unsewered county ring, including Monroe, Snohomish, Granite Falls, Darrington, and Stanwood, lots can be large and lids can sit a long way from the house. If sewage is backing up into the house, do not use the request form. Call a local emergency septic provider directly right away.
What a riser does, and the rebate that may apply
A riser brings the tank lid up to the surface, or near it, so the next pumping or inspection does not need a fresh hole in the yard. Whether a riser suits your system is a question for the provider once the lid has been found. As guidance only, local cost guides used on this site put a riser in the $300 to $600 range. Eligible residential owners may also receive a Savvy Septic rebate of $50 per riser, up to two risers, as checked November 6, 2026, subject to the programme's workshop, existing-system, certified-contractor, and application rules. New riser lids are claimed under the riser rebate, not under the minor-repair rebate. Our rebates guide and costs page have the full rules and the sourced riser figure. Leave opening and entering the tank to the professional.

FAQ
Is locating included with pumping?
A pumping visit typically starts with finding and opening the tank, and a buried lid needs digging up first. Confirm what is included before the visit. Request a locating visit on its own if the tank cannot be found, or if you are not booking a pumping yet.
Who exposes a buried lid?
The provider does that as part of the visit, once the work is agreed. Never open or enter a septic tank yourself. Tanks contain toxic gases and are a confined space.
Can a riser be fitted to my system?
Often yes, but it depends on the tank. Ask the provider once the lid has been found. A $50 Savvy Septic rebate may be available per riser, up to two, where eligible, after the county's free workshop.
How much does a riser cost in Snohomish County?
Guidance only, never a quote. Local cost guides used on this site put a riser at $300–$600. Only the provider can confirm a price for your tank.
