Understanding Spokane Valley's Septic System Regulations

All septic system maintenance and repair work in Spokane Valley falls under the jurisdiction of the Spokane Regional Health District (SRHD). The primary goal of these regulations is to prevent sewage contamination of groundwater, which is a critical concern for the community's health and environment ¹.

Before any repair, modification, or expansion of your On-Site Sewage System (OSS) can begin, you must obtain a permit from the SRHD. Starting work without a permit can result in fines and legal complications. The permitting process ensures that repairs are performed to code by licensed professionals, safeguarding your property and the community.

Regular inspections are not just a recommendation-they are a legal requirement. The frequency depends on your system type:

• Conventional Gravity Systems: Must be inspected at least once every three years.
• Alternative/Pump/Advanced Treatment Systems: Require an annual inspection due to their mechanical complexity.

If an inspection reveals a system failure-such as surfacing sewage, slow drains, or backups-the malfunction must be corrected immediately. All inspection reports must be submitted to the SRHD Liquid Waste program within 60 days of completion ².

Common Septic Repairs Needed in Spokane Valley

Local septic service companies, such as Gobers Septic and Lilac City Septic, routinely address a range of issues specific to the soils and systems in our area ³. Understanding these common repairs can help you identify problems early.

Tank-Related Repairs

The septic tank itself can suffer from age, ground shifting, or lack of maintenance.

• Baffle Repair or Replacement: The inlet and outlet baffles inside the tank prevent solids from flowing into the drainfield. When these break, it can lead to rapid drainfield clogging and failure ⁴.
• Riser Installation: Many older tanks are buried deep underground. Installing risers brings the tank access lids to the surface, making future inspections, pumping, and repairs much easier and less costly ⁵.
• Tank Replacement: A severely cracked, collapsed, or leaking tank cannot be repaired and must be replaced. This is a major excavation project but is necessary to prevent environmental contamination.

Drainfield Rehabilitation

The drainfield (or leach field) is where treated wastewater is dispersed into the soil. It's often the most expensive component to fix.

• Pipe Repair/Replacement: Perforated pipes in the drainfield can become crushed, disconnected, or clogged with solids and roots, preventing proper effluent distribution.
• Soil Restoration: Sometimes, the soil itself becomes compacted or clogged with a biomat, a layer that prevents absorption. Techniques like fracturing or replacing the soil may be required ⁶.

System Component Servicing

Many systems, especially in challenging lots, use mechanical components.

• Lift Station or Pump Repair: Pressurized systems and those with pumps require functional equipment to move effluent. Repairing or replacing failed pumps, floats, and alarm systems is a common service ⁷.
• Sewer Line Repair: The pipe running from your home to the septic tank can crack, collapse, or become blocked by roots, requiring excavation and repair.

The Inspection Process: Professional vs. DIY

Identifying the need for repair starts with a thorough inspection. Homeowners in Washington State are legally permitted to perform their own inspection on a gravity system, though many opt for a professional ^{8 9}.

Steps for a DIY Inspection

If you choose to inspect your own conventional gravity system, follow these key steps ^{10 11 12}:

1. Locate Your System: Start by finding your tank and drainfield. You can request "as-built" records from the SRHD, which often include a diagram.
2. Uncover Access Ports: Carefully excavate to expose the tank's manhole and inspection port lids.
3. Check Liquid Levels: The wastewater level inside the tank should be below the outlet baffle. A level higher than the outlet indicates a blockage in the drainfield.
4. Inspect Tank Integrity: Look for visible cracks, signs of leakage, or strong sewage odors around the tank.
5. Measure Sludge and Scum: Use a simple "sludge judge" or pole to measure the layers of solid waste. If the sludge or scum layer is too thick (typically more than one-third of the liquid depth), pumping is urgently needed.
6. Survey the Drainfield: Walk the drainfield area. Look for soggy ground, surfacing effluent, unusually lush grass, or foul odors-all signs of failure.
7. Submit Your Report: Complete the official Washington State Department of Health inspection form and submit it to SRHD within 60 days ¹³.

Benefits of a Professional Inspection

Hiring a licensed professional for your septic system inspection offers several advantages:

• Expertise: They can identify subtle signs of trouble you might miss.
• Compliance: They guarantee the report will meet all SRHD requirements.
• Safety: They have the equipment and knowledge to open heavy lids and work around hazardous gases safely.
• System Knowledge: They can inspect all system types, including complex alternative systems with pumps and electrical components.

Understanding Repair and Replacement Costs

The cost of septic work in Spokane Valley varies widely based on the repair's scope and the system's complexity. Below are general price ranges, though you should always get multiple local estimates ^{14 15}.

• Routine Inspection: $500 - $900
• Tank Pumping/Cleaning: $400 - $900
• Minor Repairs: Fixing or replacing baffles, installing risers, or repairing a pump typically ranges from $200 to $800.
• Major Drainfield Repairs: Partial or full drainfield rehabilitation is a significant undertaking, with costs ranging from $5,000 to $25,000 or more.
• Complete System Replacement: If a system is beyond repair, installing a new conventional or alternative system can easily exceed $15,000 to $30,000+¹⁶.
• SRHD Permit Fees: Permit costs vary. Contact the SRHD Liquid Waste program at 509-324-1560 ext. 1 for the most current fee schedule ^{17 18}.

Maintaining Your System to Avoid Costly Repairs

The best repair is the one you never need. Proactive maintenance is far less expensive than emergency fixes.

• Pump Regularly: Have your tank pumped every 3-5 years, or as indicated by inspections.
• Conserve Water: Spread out laundry loads and fix leaks to avoid hydraulically overloading the system.
• Mind What You Flush: Only human waste and toilet paper should go down the drain. Avoid chemicals, grease, wipes, and feminine hygiene products.
• Protect the Drainfield: Never drive or park on it, and keep roof drains and landscaping runoff directed away from the area.
