Unfortunately, I don't have that type of project cost information on hand, but I do know that costs for this type of service can vary based on a number of factors:

- How far is the septic tank installation site from the home's main drain? The greater the distance, the higher the cost.

- What kind of access issues may be present? Costs may increase with installations on or around steep slopes, wooded areas or in areas where property improvements are nearby.

- What kind of septic tank or system will be installed? With any purchase, products can/will vary in price & quality by manufacturer.


I know this is a vague answer to your specific question, but I would highly recommend obtaining at least three estimates from highly rated and well qualified contractors with experience in this type of work.

Depends a great deal on your soil type and the lay of the land near your house, and the distance to yours and your neighbor's water wells, if any, and nearby waterways, and depth to bedrock. An ideal case, with no nearby wells or waterways and free-draining sand or gravel ground can be a little as $5000, but $10,000 is probably a more general figure. With difficult ground conditions, high groundwater, shallow bedrock, deep frost penetration area, etc can run as high as $25,000 for a "raised-pad" and insulated system.

I am assuming here you are talking an initial installation on a new house. If your problem is just flow problems in an old system, then a cheaper alternative might include a larger and multi-chamber septic tank (to trap more of the solids), or just building a new leach field or extending the leach field off the existing system and pressure-flushing the existing leach drain pipes, which you might get for $5000 or so in normal conditions.

I would advise bringing in a civil engineer who does septic design to assess your situation - in most areas any septic system design has to be done by a civil engineer anyway.
