This new video covers a couple of issues. This system was about 10 years old. As you will see, the concrete riser was in pretty bad condition. The deterioration was caused by the by-products of the anaerobic treatment process. The anaerobic bacteria produces hydrogen sulfide gas. The hydrogen sulfide gas mixes with low levels of oxygen and moisture producing sulfuric acid. The sulfuric acid degrades the concrete. This same reaction takes place just above the water line in the tank, silently eating away at the tank walls. Eventually the acid breaches the outside wall and the tank begins to leak. If not addressed, this can also create a safety issue when the tank becomes too weak to support the earth above it. The failure typically occurs when an additional load is applied e.g. walking on the tank or lawn mowing equipment, etc. Depending on the tank construction this can be a catastrophic failure with immediate collapse.
Many homeowners install an Aero-Stream Remediation system when installing a septic tank riser. The aerobic action of the remediation system immediately halts all further deterioration of the tank. Installing a new septic tank may cost $2,000 – $3,000 depending on the size of the septic tank, the site conditions, and where you live. Many states require the entire system be upgraded to current codes when installing a new septic tank. This can drive the cost for the entire septic system to $15,000 – $40,000. Most homeowners do not have to go through

the extra effort to remove the old riser. They would simply remove the dirt above the tank cover as they do when getting the tank pumped. The surface is simply cleaned and the installation process can begin. Some states even provide a financial rebate if you install septic tank risers.
