Why Are ATTs Needed?
Standard septic systems are not always enough. Some properties require an ATT septic system due to:
-
Small lot sizes
-
Shallow water tables
-
Poor or limited soil conditions
In the past, the only alternative treatment option for these situations was a sand filter system. Today, newer Alternative Treatment Technologies (ATTs) provide more compact and efficient solutions. By adding an ATT unit, you can meet Oregon DEQ onsite wastewater requirements while keeping your property safe and compliant.
ATT Treatment Standards
Oregon Administrative Rules classify alternative treatment systems into two categories:
Treatment Standard 1
-
Requires more separation from the permanent water table.
-
Treated effluent still contains higher bacteria levels, so soil must provide additional filtration.
Treatment Standard 2
-
Provides additional disinfection and has proven ability to reduce nitrogen levels in wastewater.
Benefits of ATT Septic Systems
Many property owners choose an ATT system even when not required because:
-
They produce cleaner effluent than a standard system.
-
They can save space on smaller lots.
-
They offer extra protection for nearby wells and groundwater.
Maintenance Requirements
ATT systems require ongoing care to operate correctly. Homeowners must:
-
Maintain an Operation & Maintenance Service Contract with a certified provider.
-
Submit an annual report to the DEQ or local county (fees vary by county).
-
Schedule regular pumping to prevent sludge from entering the drain field.
Like a car or HVAC system, preventive maintenance helps avoid costly repairs. ATT systems may include blowers, pumps, compressors, and switches that need periodic service.
Installation & Costs
ATT systems vary in installation cost, energy use, and maintenance needs. During your site evaluation, a certified inspector will determine:
-
What type of system your property requires.
-
Whether you need Treatment Standard 1 or Treatment Standard 2.
-
The most cost-effective solution for your lot and soil conditions.
