Each septic tank installation process is going to be different and thus the prices are going to vary when it comes to how much a septic installation is going to cost. We have a handful of variables to go through in order to determine the best price for the customer and the septic tank installation business. Some of the factors we take into consideration when determining quote costs for a septic installation job: location of project, how big is the system, what type of soil are we working with, where is the system in reference to the house, what type of tank and other materials are we going to need to use, how much excavation and what type has to happen, and then the business of the season can also play a role in final costs due to the current demand for the service.
If you have a 3 or 4 bedroom house this is usually going to require a 1,000 gallon tank. The cost for a 1,000 gallon tank installation could be an average between $8,000 and $15,000. Most jobs this size are pretty routine for experience teams and can be done within a few working days or up to 5 working days. If you have a house with 5 or more bedrooms the cost is going to go up because this requires a larger septic system. With this size of a house a 1,500 gallon tank would be better suited and will cost somewhere between $15,000 and $25,000. Again there are a variety of factors that play into what your specific job is going to end up costing and these are general prices to give you an idea of what you are looking towards. If you are repairing or replacing a system then the costs could be a wide variety of numbers. There is usually extra labor to take out the old or broken parts to the system which most people don't realize. Because all septic systems are typically underground every time you still have to dig to do major repairs or replace certain elements that aren't working properly.
On some occasions there are special septic system considerations. Consider what other types of projects are already going on for that property. Heavy equipment is used for excvation and how can we get that machine to the job site without disturbing the rest of your property. Your septic system should never have any traffic over it other than foot traffic due to the fact that soil compaction can prevent your tank and drain field from functioning properly. When building a new home the septic system is installed after the outside walls are finished, but before any major outside concrete or landscape projects begin. One the tank is installed in the ground there is usually extra organic material you can then use in other locations of your property.
Some other costs the go along with septic installation are permits, inspections, and tests. Permits and inspections are required in most every state and environmental testing as well. The local health department is going to determine how and what permits/testing is done and required. An expert on septic systems in your area will know what the current requirements are and how to obtain permits for the job. A homeowner should still take the time themselves to call and confirm everything just to make sure the job is going according to all the legal standards.
