If you're buying property, building a new home, or considering a wastewater system change in Amarillo or the Texas Panhandle, understanding the differences between septic systems and municipal sewer is essential. Each option has distinct advantages and considerations for Texas homeowners.
Understanding Your Options
In Amarillo and surrounding areas, your wastewater options typically depend on location. Properties within city limits usually connect to municipal sewer, while rural properties and some suburban areas rely on septic systems. However, some properties may have a choice, and understanding the differences helps you make an informed decision.
How Each System Works
Municipal Sewer Systems
Municipal sewer systems collect wastewater from homes and businesses through underground pipes that carry it to a central treatment plant. The city of Amarillo operates water reclamation facilities that treat wastewater before releasing it. Homeowners pay a monthly fee for this service, typically based on water usage.
Septic Systems
Septic systems treat wastewater on your property. Waste flows to an underground tank where solids settle and bacteria break down organic matter. The liquid effluent then flows to a drain field where soil provides final treatment. Homeowners are responsible for all maintenance and repairs.
Septic System Advantages
Benefits of Septic Systems
- No monthly sewer bills: After installation, you only pay for periodic pumping and maintenance
- Independence: You're not affected by municipal infrastructure problems or rate increases
- Environmental benefits: Properly maintained systems recharge local groundwater naturally
- Property value: Well-maintained systems can be a selling point for rural properties
- Longevity: Systems can last 25-40 years with proper care
- Lower lifetime cost: For many homeowners, septic costs less over time than decades of sewer bills
Municipal Sewer Advantages
Benefits of Municipal Sewer
- No maintenance responsibility: The city handles all treatment and infrastructure
- Unlimited capacity: No concerns about overloading the system with high water use
- No yard space required: No drain field taking up usable property
- Consistent performance: Works the same regardless of soil conditions
- No pumping costs: No periodic pumping expenses
- Simpler home sales: No septic inspections or disclosure concerns
Cost Comparison: Septic vs Sewer
Initial Installation Costs
Septic System Installation
- Conventional system: $6,000 - $15,000
- Aerobic system: $10,000 - $20,000
- Alternative systems (mound, etc.): $15,000 - $30,000
Sewer Connection
- Tap fee: $2,000 - $5,000 (varies by municipality)
- Line installation to main: $3,000 - $10,000+
- Total: $5,000 - $15,000+ depending on distance to main
Ongoing Costs
Septic System (Annual Average)
- Pumping (every 3-5 years): $100-$150/year averaged
- Inspections: $25-$50/year averaged
- Repairs (averaged): $50-$100/year
- Total: $175-$300/year
Municipal Sewer (Annual)
- Amarillo average sewer bill: $40-$80/month
- Total: $480-$960/year
20-Year Cost Analysis
Over 20 years, assuming average usage and maintenance:
- Septic: $10,000 installation + $5,000 maintenance = ~$15,000 total
- Sewer: $7,500 connection + $14,400 bills (20 years @ $60/month) = ~$22,000 total
These are estimates and will vary based on individual circumstances, but septic systems often prove more economical over time for properties where they're suitable.
Considerations for the Texas Panhandle
Soil Conditions
The Texas Panhandle's soil presents unique challenges for septic systems. Clay-heavy soils and caliche (a calcium carbite layer common in our region) affect drain field performance. However, experienced installers design systems to work with these conditions, using appropriate sizing and sometimes alternative technologies.
Water Table
The Ogallala Aquifer underlies much of the Texas Panhandle. Properly maintained septic systems actually help recharge groundwater, but failed systems can contaminate it. If you have a well, regular septic maintenance protects your drinking water supply.
Climate Factors
Amarillo's climate affects both systems differently:
- Winter: Cold temperatures can slow bacterial activity in septic tanks; proper depth protects pipes from freezing
- Summer: Low rainfall means less natural flushing of drain fields but also less risk of saturation
- Storms: Heavy rains (though infrequent) can temporarily overwhelm septic systems; sewer systems may experience combined sewer overflows
When Septic is the Clear Choice
Septic systems are typically the better option when:
- No municipal sewer is available (rural properties)
- Sewer connection costs are prohibitively high
- You have adequate land for proper drain field sizing
- You prefer independence from utility bills and rate increases
- You're comfortable with periodic maintenance responsibilities
- Long-term cost savings are a priority
When Sewer is the Clear Choice
Municipal sewer is typically better when:
- Your lot is too small for a proper septic system and drain field
- Soil conditions make septic installation extremely expensive
- You have high water usage that would stress a septic system
- You prefer zero maintenance responsibility
- Sewer connection is readily available at reasonable cost
- You plan to sell soon and want to avoid septic inspection concerns
Converting from Septic to Sewer
Some Amarillo-area homeowners consider converting to municipal sewer when it becomes available. This involves connecting to the main line, properly abandoning the existing septic system (required by TCEQ regulations), and beginning to pay monthly sewer fees. The decision should weigh conversion costs against potential benefits.
Note: Septic tanks must be properly decommissioned when abandoned. This involves pumping, cleaning, and either removing the tank or filling it with sand or gravel to prevent collapse. This is a TCEQ requirement and should be performed by a licensed professional.
Making Your Decision
When evaluating septic vs sewer for your Amarillo property, consider:
- Availability: Is municipal sewer even an option?
- Cost: Compare total costs including installation and long-term expenses
- Property: Do you have adequate space for a septic system?
- Soil: What will a site evaluation reveal about your property?
- Lifestyle: Are you comfortable with maintenance responsibilities?
- Future plans: How long do you plan to own the property?

Frequently Asked Questions
Does having a septic system affect home value?
A well-maintained septic system generally doesn't negatively affect home value and may even be a positive for buyers seeking rural properties with lower utility costs. However, a failing or poorly maintained system can significantly reduce property value and complicate sales. Regular maintenance and documentation are key.
Can I be forced to connect to sewer if it becomes available?
In some Texas municipalities, property owners may be required to connect to sewer when it becomes available, particularly if their septic system fails. However, policies vary. If your septic system is functioning properly and you're in an unincorporated area, you may be able to continue using it. Check with local authorities for specific requirements.
Are there financing options for septic installation?
Yes, several financing options exist for septic installation. Some installers offer payment plans, and various loan products (home equity loans, personal loans, USDA rural development loans) can cover septic costs. Some areas also have grant programs for septic system installation or repair for qualifying homeowners.
What happens to my septic system if I connect to sewer?
When connecting to sewer, your existing septic tank must be properly decommissioned according to TCEQ regulations. The tank is pumped, cleaned, and either removed or filled with inert material to prevent collapse. The drain field can typically be left in place to naturally decompose. This work should be done by a licensed professional.
