Most Camano homes rely on septic systems, and staying on schedule protects your property, your well, and Puget Sound. If you are not sure when to inspect or pump, you are not alone. This guide lays out your Camano-specific maintenance schedule, what changes at sale, and simple steps to keep your system healthy. Let’s dive in.
Why septic maintenance matters on Camano
Septic systems are common across Island County, and many households also use groundwater for drinking. Proper care prevents failures that can harm local waters and shellfish beds. Island County Environmental Health provides rules, records, and training so you can manage your system with confidence. Review the county’s program overview for local guidance and contacts on the Onsite Sewage Systems page.
Know your system type
Your inspection schedule depends on your system design. Gravity systems have the least frequent inspections, while pressure and alternative systems require annual checks. Island County’s Septic FAQ explains the cadence for each system.
Your maintenance schedule
Gravity systems (tank + drainfield)
- Inspect at least every 3 years. Island County follows state rules for gravity systems. See the county’s Septic FAQ.
- Pump based on inspection findings, commonly every 3 to 5 years for a typical household. The EPA’s SepticSmart guidance explains how tank size and household use affect timing.
- If eligible, you can inspect your own system after completing the county’s HOST homeowner training.
Pressure systems (tank + pump)
- Inspect annually. Island County requires more frequent checks for systems with pumps or controls. See the county’s Septic FAQ.
- Follow manufacturer maintenance for alarms, floats, and control panels. Pumping frequency depends on use and findings.
Alternative or proprietary systems
- Inspect and service annually with a licensed maintenance provider. Some designs require service contracts or manufacturer-certified technicians. Island County details requirements in the Septic FAQ.
Simple homeowner checklist
- Keep lids accessible. Add risers and note locations in your home file. The county’s maintenance pages and onsite program stress accessibility for faster, less expensive service. Start with the Onsite Sewage Systems page for local maintenance resources.
- Inspect on schedule, and pump when your inspector advises. The EPA recommends using sludge and scum levels to decide when to pump.
- Clean the effluent filter when the tank is pumped, or as your provider recommends.
- Reduce water loads. Stagger laundry, fix leaks, and use efficient fixtures. The EPA’s tips help prevent overloading.
- Skip additives unless approved by the Washington Department of Health. Owner responsibilities and limits on additives are defined in WAC 246-272A-0270.
- Protect the drainfield. No parking or structures on top, and direct roof and footing drains away. See EPA best practices.
Signs of trouble
Watch for slow drains, gurgling, sewage odors, wet or spongy areas near the tank or drainfield, or backups into the home. Address issues early to avoid bigger repairs. The EPA’s SepticSmart guide lists common warning signs and actions to take.
When you sell a Camano home
Plan ahead so septic does not delay closing. Island County requires a current inspection at time of sale if one has not occurred within the system’s compliance period. See details in the county’s Realtor Resources.
Washington has also adopted a statewide property-transfer inspection. Beginning February 1, 2027, sellers must obtain a third-party inspection unless the local health officer waives it for systems with recent compliant inspections. See the rule update in the WAC notice. Keep records and as-builts organized in advance using the county’s Parcel and As-built portal.
Who to hire and what it costs
Hire Island County–licensed designers, installers, maintenance service providers, and pumpers. The county lists contacts and credentials on its Hiring a Professional page.
Inspection fees vary by system type and how easy it is to access lids. Island County notes inspection costs commonly range around the low hundreds of dollars, and pumping costs vary by tank size and site access. For sale timelines and typical cost considerations, review the county’s Realtor Resources, and always request itemized quotes.
Keep complete records
Save every inspection, pumping, and repair receipt, plus your system’s record drawing. Organized records support smooth sales, help providers work faster, and can lower service costs. Many documents are available through the county’s Parcel and As-built portal.
Keeping your Camano septic system on schedule protects your home, protects local waters, and keeps real estate timelines predictable. If you want a calm, well-managed sale or purchase with septic at the forefront, reach out to Hawkins & O'Bryant for thoughtful strategy and next steps.
