Choosing the Right Septic System for Your Property in King and Snohomish Counties
Selecting the right septic system for your property is crucial, as it ensures long-term performance, low maintenance costs, and compliance with county regulations. In King and Snohomish Counties, where soil conditions, property sizes, and local regulations vary widely, understanding the different options available can help you make an informed decision. Here’s a comprehensive guide to help you choose the best septic system for your needs.
Factors to Consider When Choosing a Septic System
- Soil Composition and Site Evaluation
- The soil on your property plays a critical role in septic system selection. Proper drainage and filtration are essential for the system’s effectiveness. Before any design, a soil log test and site evaluation are necessary to determine the soil type, depth, and water table level. We provide soil log testing and feasibility studies as part of our services to ensure the chosen system is suitable for your site’s specific conditions.
- Property Size and Layout
- The size and layout of your property will influence the type of septic system you need. For properties with ample space and good soil conditions, a conventional gravity system might be the best choice. However, properties with limited space, steep slopes, or poor soil conditions may require an alternative system, such as an OSCAR system or a sand-lined drip irrigation system.
- Water Usage
- Your household’s water usage impacts the size and type of septic system you need. Homes with larger families or high water usage may require advanced treatment systems that can handle increased wastewater volumes, such as the NUWater BNR600 system. These systems are designed to provide effective wastewater treatment even under high usage conditions.
- Regulations and Permitting
- Both King and Snohomish Counties have specific regulations regarding septic system installation, including permitting, setback requirements, and environmental protections. It’s crucial to work with a professional design company that is familiar with local regulations. Our team has over 30 years of experience navigating the permitting process and ensuring compliance with county health department standards.
Types of Septic Systems We Design
- Conventional Septic Systems
- These systems are ideal for properties with suitable soil conditions and adequate space. They use gravity to move wastewater through the tank and into a drain field for natural filtration. We offer a variety of conventional systems, including:
- Gravity Distribution
- Pump to Gravity
- Low Pressure Distribution
- These systems are ideal for properties with suitable soil conditions and adequate space. They use gravity to move wastewater through the tank and into a drain field for natural filtration. We offer a variety of conventional systems, including:

- Alternative Septic Systems
- When soil conditions or space limitations prevent the use of conventional systems, alternative systems become necessary. These systems provide advanced treatment and can be customized to suit challenging sites:
- OSCAR Systems: Ideal for properties with space constraints or poor soil conditions. They use subsurface drip irrigation to distribute treated wastewater. Check out our recent OSCAR system installations in Snohomish County to see how this solution can work for your property.
- Sand-Lined Drip Irrigation: Provides efficient wastewater treatment and is suitable for areas with high water tables or inadequate soil filtration. Learn more in our blog post on sand-lined drip irrigation.
- NUWater ATU (BNR600): This advanced treatment unit provides superior wastewater treatment for properties with high usage or sensitive environments. See our installation of the NUWater BNR600 on Vashon Island.
- When soil conditions or space limitations prevent the use of conventional systems, alternative systems become necessary. These systems provide advanced treatment and can be customized to suit challenging sites:
How We Help You Choose the Right System
