Changes coming to Snohomish Septic Regulations

We rely on septic systems working well to make sure that everyone in our community is healthy. This means septic systems have to meet specific design, installation, and maintenance requirements. These requirements are set in codes and regulations. 

This year, we are revising septic system regulations in Snohomish County to comply with new state rules and address local issues. This is part of a broader effort to update the Snohomish County Board of Health Code. These changes may affect you, and we want to keep you in the loop!

Maintenance Reminders

Your drainfield plays a crucial role in treating wastewater, and keeping it covered with the right vegetation is essential for its health. Grass is an ideal choice because it prevents erosion and keeps soil microbes happy, helping them do their job of breaking down waste. 

If grass doesn’t grow well in your area, consider native, shallow-rooted plants like Bunchberry or Kinnickinnick. Shallow-rooted plants are key because they won’t clog pipes or drip lines, and they’re less likely to seek out the water dispersed by your system. Avoid plants with deep or aggressive roots, as they can infiltrate your system and cause costly damage. Some drainfields are buried a few feet underground, while others are as shallow as 6 inches. Always consult with a nursery professional before choosing plants other than grass. 

A healthy plant cover not only protects your drainfield but also ensures your septic system runs smoothly for years to come! For more information, visit our septic landscaping webpage.

Did you know?

Scraping food scraps into your compost instead of rinsing them down the drain is one of the best ways to keep your septic system running smoothly. When food particles, grease, and oils enter your plumbing, it can clog pipes and overload your septic tank. To prevent this, use a sink strainer to catch scraps and be sure to scrape your dishes into the compost bin before washing. Your septic system and the environment will thank you! 

Baker's Beware: Working with dough? Sticky dough and batter can harden in pipes, creating a recipe for stubborn clogs and septic troubles. Always toss leftover dough in the compost or trash - not the sink. Protect your pipes while perfecting that homemade sourdough loaf.
