The SOLAR AIR II wastewater treatment plant (your aerobic septic system) should be filled with clean water, usually from the homeowner’s water supply. As stated in the installation instructions, once all of the proper connections have been completed, the tank has been filled with water and the blower is turned on, the system is now ready to be operated.
It should be expected for the start-up process to take ten to twelve weeks to develop a population of microoraganisms or bacteria that can properly digest the wastewater from normal household use.
