The system introduces air into the wastewater treatment process to promote the growth of aerobic bacteria, which break down organic matter more effectively than anaerobic bacteria used in conventional systems

There are 4 treatment component steps of an Aerobic Septic System. 

• The Pretreatment Tank is the initial tank where solids settle, similar to a conventional septic tank.
•  The next treatment step is where air is introduced to the wastewater to promote aerobic bacterial activity.
•  The third step is the disinfection step. This is where treated water is disinfected using chlorine, Ultraviolet light or other methods. 
• The final step is where the treated water is either dispersed throughout a surface (spray irrigation ) or a subsurface drain field

How to know if TRWD is the authority

If the property is:

Near Cedar Creek Lake

Near Richland-Chambers

Inside TRWD watershed

Then TRWD likely handles septic permits.

Otherwise:

County handles it.

Quick comparison

🟦 What TRWD actually does for septic (OSSF)

Where TRWD is the authorized agent, it performs the same core duties a county OSSF office would.

1️⃣ Permitting

TRWD:

Reviews septic permit applications

Approves designs

Issues construction permits

Issues operating permits after inspection

TRWD septic application example:
👉 https://www.trwd.com/resource/septic-system-application/

2️⃣ Inspections

TRWD:

Inspects installations

Confirms compliance with TCEQ Chapter 285

Approves systems before operation

TRWD application language confirms operation permits issued after inspection.

3️⃣ Enforcement & Compliance

TRWD can:

Investigate failing systems

Require repairs

Enforce maintenance

Protect reservoir water quality

TRWD is authorized to regulate OSSFs to protect water supply.

4️⃣ Maintenance Oversight

TRWD may require:

Aerobic maintenance contracts

Service documentation

Water-quality protections

These rules are stricter near reservoirs.

🟦 Why TRWD is involved at all

TRWD is primarily a regional water-supply authority.

It:

Owns and operates major reservoirs

Protects drinking-water sources

Regulates septic near lakes

TRWD supplies raw water to 70+ customers across an 11-county region.

Reservoirs they manage include:

Cedar Creek Reservoir

Richland-Chambers

Eagle Mountain

Lake Bridgeport

Because septic failures near reservoirs affect drinking water, TRWD has jurisdiction in those watershed zones.

TRWD septic authority typically applies to:

Henderson County

Cedar Creek Reservoir area

Lakefront developments

Certain watershed zones

Navarro County

Richland-Chambers Reservoir area

Kaufman County

Cedar Creek watershed areas

Tarrant County

Some reservoir-adjacent zones

Wise County

Lake Bridgeport watershed

Anything that isn’t liquid that enters the treatment system. Solids can be trash or sludge.

A v-shaped opening usually found on one side of a weir. The v-notch provides a means of controlling flow into the weir and separating solids from the final effluent.

The system introduces air into the wastewater treatment process to promote the growth of aerobic bacteria, which break down organic matter more effectively than anaerobic bacteria used in conventional systems

There are 4 treatment component steps of an Aerobic Septic System. 

• The Pretreatment Tank is the initial tank where solids settle, similar to a conventional septic tank.
•  The next treatment step is where air is introduced to the wastewater to promote aerobic bacterial activity.
•  The third step is the disinfection step. This is where treated water is disinfected using chlorine, Ultraviolet light or other methods. 
• The final step is where the treated water is either dispersed throughout a surface (spray irrigation ) or a subsurface drain field
