Snohomish County will pay you to maintain your septic system. Not much — but real money, for work you probably need anyway. The county's Savvy Septic programme offers up to $500 in rebates for routine maintenance, plus grants for low-income homeowners facing a major repair or replacement. Between 2023 and 2025, homeowners claimed 1,922 rebates worth nearly $223,860. This guide lists every amount, the eligibility rules, and the order to do things in — because the order matters: do the workshop first, or the rebate is not available.
The rebate table
| Work | Rebate |
|---|---|
| System inspection | $100 |
| System pumping | $100 |
| Riser installation, per riser with lid | $50, up to 2 risers |
| Minor repairs | Up to $200 |
| Combined maximum | Up to $500 |
All four amounts are published on the county Health Department's Rebates page and on the programme's own site, savvyseptic.org. Say "up to $500" and "first-come, first-served," exactly as the county does — funding is distributed in order of application until it is exhausted, and the county's page states funding is currently available.
The minor-repairs list is specific. Eligible work includes baffle replacement or repair, pump replacement or repair, distribution-box replacement or repair, fixing or replacing a cracked transport line, effluent filter installation, switching to a different lateral in a step-down system, repair or replacement of an alarm system, timer, control panel or other electrical equipment, gallon meter installation or repair, charcoal filter installation or replacement, headworks replacement or repair, correction of a settled transport line, and tank, lid, or riser resealing. Not eligible: mainline or drainfield jetting, stress tests, cleaning processes such as cleaning a filter — and new riser lids are not redeemable under the minor-repair rebate, though they can be claimed under the riser rebate.
The workshop comes first
The single most important eligibility rule is the order of operations: complete the county's free online Septic Care Workshop before the work, because the workshop is what makes the rebate available. The workshop is free and online, and 1,303 homeowners took it between 2023 and 2025. Other rules, from the programme's information sheet: you must own the property, the property must be in Snohomish County, the work must be completed by a certified provider, and the work must have been done in the last 12 months. For the inspection rebate specifically, only full system inspections with an inspection report uploaded to the county's OnlineRME database by your service provider are eligible — drainfield evaluations and service-call charges are not.
There is one more rebate worth knowing about if you live in certain neighbourhoods: the Tulalip Tribes offers a reimbursement of up to $500 for septic system inspections for homeowners in Sunny Shores, Tulare, Spee-Bi-Dah, Tulalip Shores, and Priest Point. Contact Valerie Streeter at the Tribes for details — the county's rebates page lists the contact.
Grants for failing systems
Rebates cover maintenance. Grants cover the expensive problem: a failing system that needs a major repair, replacement, or connection to sewer. The programme's information sheet advertises grants up to $30,000 for qualifying low-income homeowners — but read the fine print before relying on that figure. The county's live Replacement Grant fact sheet states that replacement grant funding may not exceed $20,000 for one property, with eligibility at or below 60% of the Washington State Median Household Income, confirmed through Snohomish County Weatherization. The two county documents disagree, and the fact sheet is the more specific and more recent source for replacement grants — so treat $30,000 as the programme's advertised ceiling and $20,000 as the cap in the county's own replacement-grant terms, and check the current terms at savvyseptic.org or by calling (425) 388-3636 before planning around either figure.
Other grant terms from the fact sheet: the applicant must own and live on the property, the property must be in Snohomish County, and the system must be determined to be failing. The homeowner must also apply for a Repair Permit from the Health Department — the application fee is $300, of which the applicant pays $100. Grant funding is limited and first-come, first-served. Between 2023 and 2025 the grants helped 15 low-income households replace failing septic systems, with more in progress, and 29 failing systems were repaired or replaced in total. The programme is a partnership with the Washington State Department of Ecology and Craft3, and low-interest loans are also available through it.
How to claim, step by step
- Take the free online Septic Care Workshop at savvyseptic.org — before any work, not after.
- Hire a certified provider for the inspection, pumping, riser, or repair. Ask them to upload the inspection report to OnlineRME where a report is required.
- Keep the invoice and the report. The rebate applies to work done in the last 12 months.
- Apply at savvyseptic.org, or call (425) 388-3636 or email savvy.septic@snoco.org. Funding is first-come, first-served, so apply promptly.
- For a grant, start with the pre-application form; county staff will notify you of eligibility, then ask for a full application to determine income eligibility, and you will also need the Repair Permit.
What this is worth against real local prices
Pumping in Snohomish County typically runs from $650, so the $100 pumping rebate covers roughly a sixth of a typical visit. A routine inspection typically runs around $500, so the $100 inspection rebate covers a fifth. A property-transfer inspection typically runs $750 plus the $245 county fee — the rebate does not touch the county fee, only the contractor's inspection charge. The real value is cumulative: inspection plus pumping plus two risers plus a minor repair is the full $500, and for a homeowner facing a failing system, the grant — even at the $20,000 cap in the county's fact sheet — is the difference between a repair that happens and one that does not. Our Snohomish County septic costs page lists the local prices these rebates sit against, and our guide on septic pumping costs explains the pumping price in detail.
