How Long Should My Commercial Septic System Last?
It truly does depend! If your employees and customers do their part by avoiding flushing harmful things, and if you have a robust regular maintenance plan in place, with regular pumping, inspections, and maintenance, your system can last you 20+ years depending on use.
But if you aren’t as proactive, results can really vary. Our Commercial HomeField Advantage plans are designed to make this whole process easy for you (and easy on your budget).

What are the Treatment Components of an Aerobic Septic System?
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

What is the treatment process for an Aerobic System Maintenance?
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
Living with your Septic or Aerobic System: Quick Homeowner Tips:
Owning a septic or aerobic treatment unit means you’re running a mini wastewater system in your yard. Taking care of it keeps your home safe, your yard clean, and your water healthy.
💧 Watch Your Water Use
Spread out laundry loads instead of doing many in one day.
Don’t overload the system with too much water at once.
🚫 Be Careful What You Flush
Skip additives, yeast, or special treatments — your system doesn’t need them.
Limit harsh cleaners or chemicals; they kill the good bacteria your system relies on.
🍴 Kitchen Habits Matter
Garbage disposals add extra solids that overwhelm the system.
The more food waste that goes down the drain, the more often you’ll need pump-outs.
🌱 Take Care of the Spray Field (Aerobic Units)
Keep grass or plants growing in the spray area to soak up water and nutrients.
Remember: even disinfected water may still carry germs, so avoid standing water.
✅ Stay on Top of Maintenance
Follow your maintenance contract and inspection schedule.
Be mindful of what goes down the drain — small changes make a big difference.
A little care goes a long way. Good habits keep your system working longer, save you money, and protect your family and the environment.
What are Solids?
Anything that isn’t liquid that enters the treatment system. Solids can be trash or sludge.

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
Living with your Septic or Aerobic System: Quick Homeowner Tips:
Owning a septic or aerobic treatment unit means you’re running a mini wastewater system in your yard. Taking care of it keeps your home safe, your yard clean, and your water healthy.
💧 Watch Your Water Use
Spread out laundry loads instead of doing many in one day.
Don’t overload the system with too much water at once.
🚫 Be Careful What You Flush
Skip additives, yeast, or special treatments — your system doesn’t need them.
Limit harsh cleaners or chemicals; they kill the good bacteria your system relies on.
🍴 Kitchen Habits Matter
Garbage disposals add extra solids that overwhelm the system.
The more food waste that goes down the drain, the more often you’ll need pump-outs.
🌱 Take Care of the Spray Field (Aerobic Units)
Keep grass or plants growing in the spray area to soak up water and nutrients.
Remember: even disinfected water may still carry germs, so avoid standing water.
✅ Stay on Top of Maintenance
Follow your maintenance contract and inspection schedule.
Be mindful of what goes down the drain — small changes make a big difference.
A little care goes a long way. Good habits keep your system working longer, save you money, and protect your family and the environment.
What are Solids?
Anything that isn’t liquid that enters the treatment system. Solids can be trash or sludge.

What are the Treatment Components of an Aerobic Septic System?
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

What are the special considerations I must ensure I follow for my septic system inside of city limits in Rockwall County, Texas?
Jurisdiction & Permitting
Even inside city limits, the Rockwall County Environmental Health Coordinator is responsible for OSSF permitting, inspections, and enforcement in many cases. rockwallcountytexas.com
Before issuing building permits, cities require that OSSF system plans and related documentation be approved by the county’s designated representative. rockwallcountytexas.com
When applying for a building permit within a city, part of the requirement is that your OSSF system has the proper county approval (or city + county coordination) in place. rockwallcountytexas.com
📐 Land / Lot Requirements & System Design
Rockwall County requires that each dwelling’s septic system be installed on a lot of at least 1.5 acres (1½ acres) of “suitable land.” rockwallcountytexas.com
The OSSF permit application must include a site survey showing the system’s location, property boundaries, setbacks, and demonstrating it meets required distance separations to property lines, buildings, water sources, etc. rockwallcountytexas.com
Your design must follow county and state minimum standards (30 TAC Chapter 285), but local rules may impose more stringent setbacks or buffer requirements.
🛠️ Repairs, Alterations & Modifications
Any repairs, modifications, or extensions to your existing OSSF (especially when changing the footprint, adding spray fields, or upgrading to an alternative system) will require county approval via a repair or modification application. rockwallcountytexas.com
Unauthorized alterations without permits can lead to noncompliance or enforcement action by either the city or county.
✅ Inspections, Maintenance & Enforcement
The county enforces Health & Safety Codes, Public Nuisance Laws, and septic system rules. rockwallcountytexas.com
The owner must allow access to the system for inspections or compliance checks by the county or its agent. rockwallcountytexas.com
If your system fails or causes a nuisance (odor, sewage surfacing, contamination), the county (or Environmental Health office) can require corrective action or enforcement. rockwallcountytexas.com
What are Solids?
Anything that isn’t liquid that enters the treatment system. Solids can be trash or sludge.

I called on the 16th of January in the midst of a hard freeze due to my septic system alarm going off. Even with the weather and its associated workload, the techs arrived the same day and resolved the issue. Awesome service seems to be the norm for this company and their techs!
