Homes inside Abilene city limits typically connect to the municipal sewer system, while rural properties throughout Taylor, Callahan, Jones, Nolan, and Runnels counties use private septic systems. The difference affects your monthly costs, maintenance responsibilities, home sale requirements, and what you can and cannot put down your drains. Understanding your system helps you maintain it properly and avoid expensive problems.
How City Sewer Systems Work
A municipal sewer connection means your wastewater flows through underground pipes to the city's treatment facility. You pay a monthly sewer fee on your water bill, and the city is responsible for maintaining the sewer mains. Your responsibility ends at your property line — you own and maintain the sewer lateral that connects your home to the city main. Inside city limits in Abilene, Clyde, Merkel, Sweetwater, and other Big Country towns, sewer service is generally available.
How Septic Systems Work
A septic system processes wastewater on your own property. It consists of a buried tank where solids settle and bacteria break them down, and a drain field where liquid effluent percolates through the soil for final treatment. You own the entire system and are responsible for all maintenance, including pumping the tank every 3 to 5 years. There is no monthly sewer bill, but you bear the full cost of any repairs or replacements.
Cost Comparison Over Time
Maintenance costs differ significantly over time. City sewer users pay a predictable monthly fee but rarely face large unexpected expenses unless their sewer lateral collapses or becomes root-clogged. Septic system owners pay nothing monthly but must budget for pumping every 3 to 5 years at approximately $300 to $500 per service, and a drain field replacement can cost $10,000 to $25,000 if the system fails due to neglect.
What You Can Put Down the Drain
What you put down the drain matters more with a septic system. The bacteria in your septic tank are living organisms that break down waste. Pouring bleach, antibacterial cleaners, paint, cooking grease, or non-biodegradable materials down the drain can kill these bacteria and cause the system to fail. City sewer systems are more forgiving because the treatment facility uses industrial processes, but you should still avoid putting grease, wipes, and non-flushable items down any drain.
Selling a Home With a Septic System
Home sales involving septic systems face additional requirements. Most lenders in the Big Country area require a septic inspection before closing. If the system fails inspection, the seller must typically repair or replace it before the sale can proceed. This can add weeks to the closing timeline and thousands to the seller's costs. Homes on city sewer rarely face this issue unless there are visible problems with the lateral line.
Building a New Home on Rural Property
For rural properties in Tuscola, Buffalo Gap, Potosi, Lawn, Hawley, and other Big Country communities outside city limits, septic is the only option. If you are building a new home on rural property, the septic system design must be approved by the county before construction begins. Soil testing determines what type and size of system your property can support. The cost of a new septic system ranges from $5,000 to $20,000 depending on the system type required.
