No matter what type of system you own, it requires routine maintenance to operate effectively and efficiently. The first way to maintain your system is to use it properly through water use efficiency, avoid using chemicals and not using your system as a trash can.
Many systems will have risers over tank lids to increase the accessibility to system components for maintenance. These risers can keep costs lower for inspections and pumping. Risers are not required, but recommended. If you do not have risers on your system, you can install them yourself or hire a professional.
Thank you for looking into the best way to care for your system. As you maintain your system, you will be protecting the natural environment, the health of your community and your "pocket book".
