Cost of Septic System: From Planning to Install

The cost of a septic system cannot be pinned down to a single price. There are a lot of variables that need to be accounted for and some cannot possibly be known without visiting the physical location of where the unit is intended to be placed. A general ballpark is around $10,000-12,000 for a traditional gravity-fed unit, but we’ve broken down the cost of septic a system based on the processes involved, so you can get a better idea of what to anticipate. If you need to work with hard figures, call us, as your total price may be lower or considerably higher than what’s outlined here.

Cost of Septic System Planning, Design, and Install

A properly designed system is an engineering feat. When everything is laid out properly, your unit will run efficiently and last for decades. The fees associated with the planning, design, and install will typically run from $1,500-4,000. This includes things like:

Site Survey: General things about the land will be noted, such as how much vegetation will need to be removed, as well as how difficult accessing the property is. The slope of the land makes a difference as well. Typical units need a 15% grade or less. Anything more than this may require an alternative unit. The assessor will also have to verify where the water table sits, to determine if a standard leach field is appropriate.

Perc Test: The percolation test determines whether the soil absorbs water at a good rate. If it soaks in too fast or too slow, a leach field may not be appropriate. A mound system may be an alternate used in planning, though if the soil is totally not an option, the fee for an on-site sanitization unit may push your total price to over $20,000. This is fairly rare, especially in Georgia.

Written Plans: Armed with the information, written plans and the layout are created. This allows the company to provide you with an estimate and get approval from the county to begin work.

Permits: Depending on where you’re located, multiple permits may be necessary.

Price of the Tank

Most homes today find a 1,000-gallon reservoir to be sufficient for their needs. Concrete tends to be the best choice and it may run $800-1,000 by itself. Fiberglass tends to be comparably priced, though it’s generally only used when the site conditions make hauling a cement reservoir difficult. Plastic is a final option. It’s not as durable, but it may shave a couple hundred dollars off the price. Steel reservoirs, though once acceptable, are illegal in many places and rust quickly, so they tend to not be a viable option. Because you may need a larger or smaller reservoir, your costs may be different.

Price of the Leach Field

The leach field has the job of discharging the water/ effluent into the soil where it finishes treatment. The costs associated with the leach field generally account for half of the overall expenses because there is so much involved.

Excavation: Trenches must be dug to allow for all the lines to be placed. These are generally 8-12 inches wide and 2-3 feet deep.

Pipes: Soil conditions determine how large the leach field needs to be. As a starting point, approximately 4,500 square feet will be needed, but some may need as much as 9,000 square feet or more. For every 100 feet of pipe, $65-80 should be set aside.

Gravel/ Rocks: The trenches are filled in with gravel or rocks to help the effluent distribute evenly. Depending on how it is sourced and how far it has to travel to get to you, it will run $15-30 per ton.

Additional Costs

There may be some additional costs as well, such as those associated with including risers in the design. These bring the level of the access ports up to ground level, so you don’t have to excavate (or pay to excavate) when the unit needs pumping or service later. They can run $100-200 or more, depending on the size and the materials used.

Very Affordable

They easily figured out what's wrong and they told me they could fix it right away. They were so friendly and were able to keep me calm as they resolved this issue. I will be calling them again in the next couple of years to have it maintained. I really felt that this was one of my best decisions. I am thankful.
