The Process of Septic System Installation

1. Soil Feasibility Study

County government regulates the installation of septic systems, and the first thing they require is a soil feasibility study. In this process, a test pit is dug up and an official comes to evaluate the suitability of the soil for absorbing and filtering effluent, or liquid waste. The quality of the soil will determine in large part the size of drainfield required for the septic system to work appropriately. When you contract with Byers Septic Tank Service, we take care of ordering this study and working with the county to build a system which fits the soil.

2. System Design

Our experienced team of septic system pros uses the results of the soil analysis along with household data and equipment specs to develop plans for a system that will work great for you – whether that’s a conventional system or an advanced treatment system. We prepare the design and submit plans to the county for approval.

3. Septic System Permits

Working with the county, we manage any difficulties with the plans we have developed to ensure that the project obtains all necessary permits and can proceed legally.

4. Material Ordering

Working through our long-time contacts in the septic tank industry, we arrange for the delivery of the materials needed to install your septic tank and drainfield.

5. Septic System Installation

Finally, we dig out and install the septic tank and drainfield and connect them to each other and to the house. Your system is ready to go!

Types of Septic System

There are two varieties of septic system that we can install for our Oregon customers.


As the name implies, this is our standard system which is less expensive and works perfectly if the soil conditions are right for a full-sized drainfield, and there is the space for it.

Alterative Treatment Technology

If space is lacking for a conventional septic system we can install an alternative: an Orenco AdvanTex treatment system. This product acts like a sewage treatment plant for an individual residence. It cleans sewage on-site to the point where it can be released into the soil. While the initial installation cost is greater than a standard system, alternative treatment technology has a much smaller footprint and may be installed closer to the water table. Learn more about how the system works by watching the video below.

Varieties of Material for Septic Tank Installations

  • Durable Plastic
  • Plastic is usually easier to install than concrete. Plastic tanks are also less prone to cracking as they have a bit of flex to them, and are completely resistant to corrosion and erosion, meaning they can last a long time.
  • Precast Concrete
  • Concrete is extremely long-lasting and can be installed anywhere due to its inherent watertight properties. On the other hand, concrete is less resistant to corrosion than plastic or fiberglass.
  • Fiberglass
  • Fiberglass is a very durable and lightweight material, and is the most expensive option. Fiberglass septic tanks are lightweight and rigid and will not corrode, making them a relatively easy-to-install option for many applications.

Not sure which material would be best for your project? Don’t worry about it – that’s our job.

Replacement Septic Tank Installations

We don’t just do new installs! If you’re looking to get a new septic tank installed in place of an old one (we particularly find ourselves replacing old steel septic tanks), we can help. From a new tank all the way to the drainfield, we take care of permits, planning, installation, and troubleshooting. Get in touch today to schedule a consultation, and learn more at our Septic System Repair & Replacement page.

Commercial Holding Tank Planning and Installation

Certain commercial properties may not be able to access sewer services, and also not have a lot of room for a full-blown septic system. Holding tanks are the answer! These tanks simply hold waste until it can be pumped out and hauled away for treatment. If this is your situation, get in touch to learn how we can help.

Frequently Asked Questions about Septic Tank Installation

What is a septic system and how does it work?
A septic system stores solid waste for later removal and transport to a waste treatment plant, and allows liquid waste to be released safely into the ground. A conventional septic system has two main parts: septic tank and drainfield. The septic tank filters out solid waste and allows it to break down safely until it can be pumped out, while passing on liquid waste to the drainfield, which distributes it into the soil to be filtered and reused.
How much does a septic system installation cost?
Costs depend on a variety of factors such as size of the system, soil conditions, and material of the tank, so unfortunately, we cannot give a number here. Give us a call for a consultation about your unique situation.
Are there alternatives to septic systems?
There are a variety of alternatives on the market today. Our preferred system is the Orenco Advantex Wastewater Treatment System. Click here to learn more.
How long does it take to install a new septic tank?
It takes about a week from groundbreaking to initial operation, and more if you include the process of developing plans and acquiring permits.
What permits are required to install a new septic tank?
The county the job site is located in will regulate septic systems. An initial soil feasibility test must be conducted before a system can be designed and all other permits obtained. When we install a septic system, we take care of all the testing and permits so you don’t have to deal with anything.
What size septic tank will I need?
This depends primarily on the number of bedrooms in your household. The more people in the house, the larger the tank and drainfield.
