Intermittent Sand Filter Pre-treatment System
In cases of shallow soils Intermittent Sand Filter Pre-treatment system is sometimes utilized. Before effluent is sent to the leach filed it is pretreated in a Sand Filter bed. A pump tank, pump, sand filter, and leach field are installed. The leach field itself is designed depending on the soil conditions but is usually a Pressure Dose or Geo-Flow Leach Field.
The septic tank should be pumped every three to five years for proper action. Besides pumping the septic the pump, controls, and filter, should be checked and cleaned annually. The leach field itself may have maintenance needs depending on it's type and design.
As you know, this maintenance is critical to the over-all performance of the sewage disposal system, neglecting to perform this maintenance can lead to premature failure of the leach lines.
The general maintenance for your system should include all or part of the following:
Septic tank maintenance should include pumping the septic and cleaning the effluent filter every three to five years. Because the septic tank maintenance is critical to the over-all performance of the sewage disposal system, failure to perform this maintenance can lead to sedimentation and premature failure of the leach lines.
The effluent filter and Biotube filter should be removed and hosed down into the septic tank solid side annually to remove any scum and buildup.
The pump and alarm floats should be manually activated annual to verify proper operation annually.
The leach line laterals should be flushed once a year to remove any accumulated scum. A flushing valve assembly should be connected to the cleanout assembly to discharge the effluent back into the trench. If flushing is not performed, the lateral orifices will eventually clog with scum and not operate per design.
After flushing is completed the pressure head should be reset to the designs specifications.
The drainfield effluent head should be checked on each lateral annually to assure proper operation of the pump and that orifices are not clogged. Then the pump should be turned on and see that uniform head is maintained throughout the distribution system.
The primary and 100% repair area must be protected from vehicular traffic, corrals, animal enclosures, stables, structures, below or above ground pools, or any other activity that causes alterations such as grading, cuts/fills, ect. Failure to do so may void this report.
Please note that all roof drainage should be diverted away from the leach field. Irrigation in the area of the leach trenches should be kept to a minimum to avoid saturating the soil. Drip irrigation should be used.
Also we recommend water conservation should be enlisted for household water use to maximize the life expectancy of the absorption trenches. Also take care of any household leaks immediately to avoid unnecessary saturating of the leach trenches.
