Living in Seaside, Oregon, means enjoying stunning coastal views, fresh ocean air, and a unique small-town charm. But if your home relies on a septic system, you also have to deal with some very real challenges—especially in our rainy, sandy-soiled environment. Septic issues can be messy, expensive, and disruptive, but the good news is most problems can be prevented with regular maintenance and early intervention.
At Evans Plumbing, Heating, and Mechanical, we’ve helped countless homeowners in Seaside tackle septic system problems. In this blog, we’ll cover the most common septic issues in our area and how you can avoid them.
1. Slow Drains & Backups
🚨 Why It Happens:
Septic tanks in Seaside often fill up faster than expected due to high water tables and excessive moisture from frequent coastal rains. When your tank reaches capacity, wastewater has nowhere to go, leading to slow drains, gurgling pipes, or even sewage backing up into your home.
🛠 How to Prevent It:
✔️ Schedule routine septic pumping every 3–5 years (or more often for larger households).
✔️ Be mindful of your water usage—spreading out laundry loads and fixing leaks can prevent system overload.
✔️ If you hear gurgling sounds in your drains, don’t wait! Call us for an inspection.
2. Septic Tank Overflows After Heavy Rain
🚨 Why It Happens:
Seaside’s coastal climate brings heavy rainfall, which can oversaturate your drain field. When the ground is too wet to absorb wastewater properly, it can cause slow drainage, pooling water, and strong odors.
🛠 How to Prevent It:
✔️ Direct gutters and downspouts away from your drain field to prevent excessive moisture buildup.
✔️ Avoid using large amounts of water (like doing multiple laundry loads) after a heavy rainstorm.
✔️ If your drain field is frequently waterlogged, we can install drainage solutions to help prevent overflows.
3. Foul Odors Around Your Home & Yard
🚨 Why It Happens:
A properly working septic system should never smell bad. If you notice a strong sewage odor near your drains, yard, or drain field, it could mean:
Your septic tank is full and needs pumping.
There’s a clog in your pipes or venting system.
Your drain field is failing, allowing wastewater to rise to the surface.
🛠 How to Prevent It:
✔️ Schedule regular septic pumping to keep your system running smoothly.
✔️ Avoid flushing non-septic-safe items (wipes, grease, etc.) that can cause blockages.
✔️ Call Evans Plumbing if you notice persistent foul smells—it’s a sign something is wrong.
4. Pooling Water or Lush Green Grass Near Your Drain Field
🚨 Why It Happens:
If certain areas of your yard have excessively lush, green grass or standing water, it could mean:
Your drain field is oversaturated and struggling to absorb wastewater.
Your septic system is leaking, releasing untreated sewage into your yard.
🛠 How to Prevent It:
✔️ Avoid driving or parking over your drain field—this can compact the soil and damage pipes.
✔️ Plant septic-safe landscaping (shallow-rooted plants) to help absorb excess moisture.
✔️ Call us ASAP if you notice standing water—it could indicate a serious drain field failure.
5. Tree Root Intrusion & Pipe Damage
🚨 Why It Happens:
Septic pipes and drain fields are underground, making them vulnerable to tree root intrusion. In Seaside, where trees thrive in the wet climate, roots can invade pipes looking for moisture, causing cracks, leaks, and blockages.
🛠 How to Prevent It:
✔️ Don’t plant trees or shrubs near your drain field or septic pipes.
✔️ If you have existing trees near your septic system, consider root barriers or regular root cutting.
✔️ If your system is backing up frequently, we can inspect for root damage and repair any affected pipes.
