Deep Trench Gravity Flow System
The only difference between a Standard system and a Deep Trench system
is the depth of the trenches that are installed. Because the trench is
deeper there is less lineal footage needed. This type of system is
usually utilized on smaller lots where soils allow for a deeper trench.
If a Standard leach field will fit in the area designated, then a
Standard System would be utilized.
Maintenance Requirements:
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 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 any warranties.
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.
Below is a cross-section of a typical Deep Trench leach line. Please
note: this does not represent all deep trench system leach lines but one
type commonly installed in Nevada County.
