What are the Best Methods for Septic Tank Installation?

Installing a septic tank is a highly labor-intensive project that many homeowners choose to seek professional help with, but in many cases, the assistance is not required. The process of septic tank installation requires a number of steps to complete, but each of them is relatively simple, especially when the laborer has access to equipment that can expedite the digging process. After acquiring a permit for the construction and finding a dealer to deliver the septic tank, the only remaining steps are to create a leveled space that will house the tank underground and to install the drainage lines. While the particulars of this process will vary by jurisdiction and a few other factors, all of the regulatory information can be obtained from the local authority before the process begins.

Before starting a septic tank installation, the first step would be to verify the ordinances that apply to this type of construction. Many municipalities will require the drainage field coming off the septic tank to vary in length depending on the soil's ability to absorb waste, so a sample is often required before the permit can be issued. Some areas will accept a soil sample brought by the consumer, while others will require a state official to conduct the collection process—calling ahead before applying for a building permit is normally recommended. Once the actual license is obtained, there are also usually time constraints on when the construction may occur as well.

After the permits are taken care of, the next step in septic tank installation involves a trip to a retailer. Septic tanks are available in both concrete and plastic, and this decision will define how much manpower will be required to lower it into place at the jobsite. Some retailers will offer to bring a crane in order to eliminate the need for manual lifting, and this point should be discussed beforehand.

Back at the property where the septic tank installation will take place, each of the holes can be dug by hand or through the use of a backhoe or a ditch witch. Renting the digging equipment is completely optional, but in most cases, it saves both time and money when compared to hiring laborers. These areas need to be completely level in order for the septic tank to operate properly, which is why many contractors prefer renting the equipment. If industrial equipment is used, individuals should be sure to dig both of the ditches for the waste line from indoors and the drainage field before returning it.

The last phases of septic tank installation are very straightforward once each of the previous steps are completed. As long as the flooring at the bottom of the main hole is level, rock or other building materials can be used to help keep the weight of the septic tank evenly distributed. After the tank is lowered into place, both drainage lines can be set and secured according to the manufacturer's recommendations. Once the glue dries and the remaining hole is filled in, the septic tank installation is complete.
