The cost to install a system can range dramatically based on your property and home. Projects can be as much as $10,000 if an extensive leach field and large septic tank are involved. Lower pricing may be possible, but you need to be careful about cutting corners on design and materials. It's critical that you work with a design professional who is familiar with the codes that exist in your location and can take into account the expected usage on the property. Pricing on plans will vary based on your designer's hourly rate.
Although it may be tempting to cut corners on your installation, it's important to have the system sized and placed correctly. Failing to do so could lead to a system failure in the future, creating a mess in your home and leading to complications as you try to dig a new system. In some communities, large leach fields are dug to provide ample space for leached fluids to disperse. In other communities, small trenches may be used. This is cost effective at the time of installation, but consulting with locals who have used both methods may be useful as you determine whether you can afford the complications that shortcuts sometimes cause.
The installation will include placement of a large tank to contain waste products from the home. Additionally, leach lines will run to the field. Pricing of these components varies based on the materials used. Work with your installation specialist to find the right components for your property. Labor will be another significant cost, as digging, placement and covering of the area is handled.
Upon completion of your septic installation, you should have your tank pumped out periodically. Annual waste removal can ensure that your tank doesn't become over-filled.
