How do I properly maintain my aerobic treatment unit?
One of the main design criteria of ATU's is the level of aeration provided for sewage treatment. Therefore, maintaining the blower is essential to the treatment process.
Another important issue is the sludge that builds up over time. Therefore, the ATU should be pumped periodically to remove the solids that settle to the bottom. The amount of organic matter entering the ATU will determine the pump schedule. A general rule of thumb is to pump it every 3 to 5 years.
With the purchase of any ATU, the first two years of service visits are included. You need to make sure those service visits are performed by your maintenance provider. After that you will have an option to renew the service agreement.
