Covers provide access to your septic system so that your service provider can inspect and maintain your septic system. Covers can be landscaped around but must remain fully accessible.
Control Panels are the brains of the I/A OWTS and usually mounted to the side of the dwelling. They should be protected from damage and easily accessible by operation and maintenance providers.
The first three years are covered as part of the manufacturer’s warranty. However, homeowners will need to sign yearly maintenance contracts and will be responsible for maintenance costs after the 3-year warranty expires. It is anticipated that O&M will cost approximately $300 a year.
Depending on the treatment process and manufacturer’s system, the system either runs continuously or on-demand. Based on information provided by manufacturers, the systems that are provisionally approved have approximate annual electric costs ranging from $57 to $266 per year.
Homeowners should be aware that although I/A OWTS have a long track record of use in the USA, they do contain components such as pumps, floats, air compressors, and controls that may need to be replaced at some point during the useful life of the system. These component repair and replacement costs could range from $50 to $200.
Although these systems provide advanced treatment, they will still need to be occasionally pumped by a septage hauler. Depending on use of the system, it is estimated that the average system would need to be pumped out every 3-5 years. This increases the treatment and useful life of any sewage disposal system including I/A OWTS. A typical pump-out is estimated to cost $300 – $500.
Property owners are required to register their I/A OWTS with their County’s Health Department at time of Final Approval from the Department. Registration is updated every 3 years and upon property transfer. There is no cost to register your I/A OWTS, but it is critical in order for SCDHS to ensure proper function of your I/A OWTS and provide homeowners with essential news or information regarding their I/A OWTS.
