How Drainfield Rejuvenation Works.
- Drainfield rejuvenation focuses on improving wastewater treatment before effluent reaches the drainfield. By creating a more oxygen-rich environment inside the septic system, beneficial aerobic microorganisms can thrive, helping reduce organic loading and improve effluent quality.
Benefits Include
- Restores wastewater flow in many biomat-affected systems
- No excavation or yard destruction
- Extends the life of existing drainfields
- Produces cleaner, lower-odor effluent
- Environmentally responsible alternative to replacement
- Significantly lower cost than installing a new drainfield
Scientific Evidence
Approximately 10% of septic drainfields fail each year, with biomat sludge buildup being one of the leading causes.
Drainfield failure can result in:
- System backups and ponding
- Environmental contamination
- Public health risks
- Expensive drainfield replacement costs
Biomat is a layer of organic material, bacteria, and wastewater solids that forms where septic effluent enters the soil.
Research shows that a biomat layer only 0.5–2 cm (0.2–0.8 inches) thick can drastically reduce soil permeability and prevent wastewater from infiltrating into the surrounding soil.
Several factors accelerate biomat clogging:
- High organic loading from septic effluent
- Low oxygen (anaerobic) conditions
- Fine-textured soils (clay and silt)
- Excess hydraulic loading
As biomat thickens, infiltration slows until the drainfield becomes hydraulically overloaded and eventually fails.
Multiple studies have found that:
- Even thin biomat layers can significantly restrict flow.
- Introducing oxygen-rich aerobic effluent into drainfields promotes aerobic microbial activity.
- Aerobic microorganisms break down organic material more efficiently than anaerobic organisms.
- Reduced biomat thickness leads to improved infiltration and restored drainfield performance.
- Aerobic pretreatment consistently extends drainfield life and reduces failure rates.

What It Is
The RioVation® BioMaze® Suspended Biofilm Generator™ (SBG™) is a proprietary in-tank aerobic treatment technology designed to improve effluent quality and rejuvenate impaired drainfields.
How It Works
- Installs through an existing septic tank riser
- Uses floating fixed-film media pods and aeration
- Generates oxygen-rich effluent
- Promotes suspended biofilm microorganisms throughout the septic tank and drainfield
- Continuously delivers highly treated wastewater to the drainfield
Typical Effluent Quality Benefits
- High dissolved oxygen (DO)
- Single-digit BOD
- Single-digit TSS
- Reduced fecal coliform
- Reduced nitrogen levels
Unlike conventional aerobic systems, BioMaze® functions as a Suspended Biofilm Generator™, promoting biological activity not only in the tank but throughout the drainfield.
Expected Results
- Accelerated biomat degradation
- Improved wastewater infiltration
- Reduced clogging
- Extended drainfield life
- Potentially visible performance improvements within days in biomat-impacted systems
The Challenge
Biomat buildup as little as 0.5–2 cm thick can cause drainfield failure.
The Science
Research consistently shows that oxygen-rich aerobic effluent promotes biomat degradation and improves drainfield performance.
The Solution
RioVation® BioMaze® SBG™ delivers highly oxygenated, biologically active effluent that helps rejuvenate biomat-clogged drainfields, restore infiltration, and extend septic system life.

Common Signs of Drainfield Failure
- Restores wastewater flow in many biomat-affected systems
- No excavation or yard destruction
- Extends the life of existing drainfields
- Produces cleaner, lower-odor effluent
- Environmentally responsible alternative to replacement
- Significantly lower cost than installing a new drainfield
What Causes Drainfields to Fail
Over time, septic systems naturally develop a layer known as biomat. While biomat is part of the normal treatment process, excessive buildup can reduce the soil's ability to absorb wastewater, eventually causing hydraulic overload and drainfield performance issues.
Additional factors can include:
- Excess household water usage
- Poor septic tank maintenance
- Soil compaction from vehicles or heavy equipment
- Root intrusion
- Inadequate system design
- Solids escaping the septic tank
Understanding the root cause is critical before determining the best solution.

Is Your Drainfield a Candidate?
Drainfield rejuvenation may be appropriate if:
- Your system worked well for a number of years and is now struggling
- Your system is experiencing reduced absorption
- The drainfield still accepts some wastewater
- Failure is related to biomat buildup
- You want to avoid unnecessary replacement costs
A professional septic evaluation can determine whether rejuvenation is the right solution for your property.
Why Homeowners Choose Rejuvenation First
Traditional Replacement
- Expensive excavation
- Damaged landscaping
- Weeks of disruption
- New construction permits
Drainfield Rejuvenation
- Minimal property disturbance
- Faster installation
- Lower overall cost
- Preserves existing system infrastructure
Protect Your Investment!
Most homeowners never think about their septic system until problems appear. Taking action early can help prevent costly repairs and extend the service life of your entire wastewater system.
