Septic System Installation in Central Oklahoma

Sprague’s Backhoe installs conventional septic systems throughout central Oklahoma, including Blanchard, Norman, Newcastle, Tuttle, Mustang, and surrounding areas.

Septic installation isn’t a one-size-fits-all service. Every system is designed based on your soil test, property layout, and local requirements. We work directly from your soil report and coordinate the installation to meet DEQ standards.

We focus on new system installations and full replacements. While we don’t take on septic repairs or temporary fixes, we’re always happy to help you determine the best long-term solution for your property. In many cases, systems that appear to need “repairs” are simply at the end of their lifespan and are better served with a properly installed replacement.

Our focus is on properly designed, properly installed septic systems built for long-term performance. From reviewing soil reports to completing the installation, Sprague’s Backhoe takes a straightforward, detail-oriented approach to every project.

Conventional Septic System Components

We Specialize in Conventional Septic Systems

Also known as lateral line or leach line systems, conventional septic systems are often a more cost-effective and efficient option than aerobic systems when your soil allows for it. This is determined by an Oklahoma DEQ soil test.

If you need help finding a certified soil tester, contact us and we can point you in the right direction. A soil test is required for all conventional system installations and typically costs around $300.

Septic installers are not soil testers. We install systems based on the results of your soil report, not guesswork. In many cases, we’ve seen properties that were previously told they “had to go aerobic” qualify for a conventional system after a proper soil evaluation.

Conventional systems are best suited for properties with adequate space, good drainage, and minimal traffic over the lateral field area.

Most conventional systems can be installed in one day, though some projects may take longer depending on DEQ requirements and site conditions.

While your yard won’t look untouched immediately after installation, we take the time to clean up and dress the area as much as possible before we leave. There is no additional charge for final dirt work.

Ready to Get Started on a Septic System?

If you have a soil test or are planning a new build, we can help you determine the next steps and whether your project is a good fit.

The best place to start is with your soil test and property details. From there, we can review your project, confirm requirements, and help you move forward with a properly installed septic system.

Septic System FAQs

Straightforward answers to common questions about septic system installation, requirements, and what to expect.

Do I need a soil test before installing a septic system?

Yes. A soil test is required for all septic system installations in Oklahoma. The results determine the type, size, and layout of your system based on how your soil absorbs water.

Soil tests are performed by certified soil profilers and typically cost around $300. If you need help finding one, we can point you in the right direction.

Septic system costs vary depending on your soil test results, system size, and layout requirements. Because every property is different, pricing is based on your specific project rather than a flat rate.

Once you have a soil test, we can review your report and provide an accurate estimate.

Most conventional septic systems can be installed in one day. Some projects may take longer depending on site conditions, system size, and DEQ requirements.

No. We focus on new septic system installations and full replacements. In many cases, systems that appear to need repairs are at the end of their lifespan and are better served with a properly installed replacement.

No. The soil test determines what type of septic system your property can support. We install systems based on those results, not estimates or assumptions.

No. We specialize in conventional septic systems only. If your soil test requires an aerobic system, we can let you know and point you in the right direction.

Yes — heavy rain can temporarily impact how your septic system performs, especially if the ground becomes saturated. This can slow drainage and affect how efficiently your system works.

Scheduling depends on current workload, weather conditions, soil conditions, and project readiness. Because every septic installation is unique, timing can also be affected by soil testing, permitting, and site conditions. We’ll discuss scheduling expectations during the quoting process and keep you updated throughout the project.

No. Sprague’s Backhoe handles the OKIE811 locate request before work begins. However, private lines such as septic, water, propane, or sprinkler systems are not located by OKIE811 and must be identified by the property owner or a private locator.

Proper maintenance is key to getting the most life out of your septic system. Being mindful of what goes down your drains and limiting excess water usage can make a big difference.

Read our septic system do’s and don’ts

No. We install septic systems within central Oklahoma only.

Yes. A $400 non-refundable deposit is required to move forward with a septic system installation. This deposit covers the cost of the DEQ permit and allows us to begin scheduling and preparing your project. Because the permit is tied to your property and submitted on your behalf, this portion is non-refundable. The remaining balance is due at the time of installation.

Yes. Regular pumping is an important part of maintaining your septic system and extending its lifespan.

For a typical 1,000-gallon tank, pumping is generally recommended every 3–5 years, depending on usage.

A common misconception is that you only need to pump your tank once there’s a problem. In reality, by the time you’re noticing issues, the system is often already overloaded or damaged.

Staying on a regular pumping schedule helps prevent costly repairs and extends the life of your system. Routine maintenance is far less expensive than system failure.

No. We do not offer septic tank pumping services.

We focus on septic system installations and full replacements, but we’re happy to point you in the right direction if you need a reputable pumping company.
