These instructions provide a general guideline concerning when and how to pump out the Singulair system. This literaturesupplements other instructional materials included in the Singulair Bio-Kinetic System Service Manual.
In order to maximize performance, protect system components and insure protection of the surrounding environment, theSingulair system should be thoroughly checked every six months by a factory-trained Norweco service technician. Aninitial service program that provides a minimum of four service inspections during the first two years of system operationis included in the system purchase price. Renewable service contracts to extend these routine inspections after the initialprogram expires are available from the local licensed Norweco distributor.
The pretreatment chamber of the Singulair system will periodically require pumping. Because the Singulair system is abiological treatment device, the time frames listed within these instructions are estimates. Actual pumping frequency willdepend on the amount and strength of the wastewater being treated.
Handling and disposal of pretreatment chamber contents, referred to as septage, or the contents of the aeration andclarification chambers, referred to as biosolids, are regulated by local, state and federal authorities. Disposal options mayinclude land application, lagoon treatment, municipal wastewater treatment or landfill disposal. Prior to arranging for tankpumping, contact the Norweco distributor to obtain complete information on access to chambers, removing equipment,coordination of services and disposal of tank contents.
During Singulair system installation and backfilling, do not allow dirt or mud to enter the system. Once in the system, dirtor mud will form a heavy sludge which will affect settling characteristics, interfere with filtration and degrade effluent quality.
If dirt or mud enters the system, it must be removed to insure proper system operation. Removing the dirt or mud mayrequire repeated flushing and tank pumping. For additional details refer to Singulair Tank Delivery and Setting instructions.
