Sand Lined Trench Systems-Recommended Standards and Guidance
Effective Date:March 2014
Introduction
Sand lined trenches provide biodegradation or decomposition of wastewater constituents by bringing
the wastewater into close contact with a well developed aerobic biological community attached to
the surfaces of the filter media. This process requires unsaturated downward flow of the effluent
through the filter media. The media may be coarse mineral sand or equivalently sized crushed glass
meeting one of the media specifications listed in Appendix A. As a departure from the intermittent
sand filter,the media is not contained in a watertight vessel. Instead,the media is placed in trenches
or beds in the native soil. Proper function requires that influent to the sand filter be distributed over
the media in controlled,uniform doses. In order to achieve accurate dosing,these systems require
timed dosing with associated pump chambers, electrical components, and distribution network,with
a minimum of 4 to 18 doses per day(depending on sand media used) spread evenly over a 24 hour
period. The effluent is absorbed into the native soil at the bottom of the sand lined trenches,which
accomplishes dispersal into the subsoil environment and some further treatment. A sand lined trench
is a combined treatment component and soil dispersal component.
Possible Applications:
A sand lined drainfield trench(sand filter)may be selected for a site with excessively permeable
(Type 1) soils. The addition of 24 inches of filter media(coarse sand)to a pressure distribution soil
dispersal component provides the wastewater treatment not provided by the Type 1 soil. Treated
wastewater is discharged directly to the receiving soil for dispersal into the subsoil environment.
See Figure 2.1. If the soil adjacent to the layer of drainrock atop the sand media is Type 1,
additional filter media sand or an impervious material must be placed between the type 1 soil and the
drainrock making up the trench's sidewalls and end walls to prevent short-circuiting. When sand is
used for protection against short-circuiting, a minimum of six(6) inch width of filter media sand is
required. The sand bed under the drainrock will also be widened by six(6) inches on each side. See
Figures 2.2 and 2.3. When an impervious material is used,it must be 30 mil PVC and must extend
from above the gravel bed to six(6) inches below the gravel/sand interface. See Figure 2.4.
A sand lined drainfield trench(sand filter)may also be selected for a site that has its more suitable
soils for dispersal(and further treatment) at a depth greater than three feet. Filter media(course
sand) is placed below the drain rock to provide adequate levels of treatment so deeper soils more
suitable for dispersal into the subsoil environment can be"reached." See Figure 3.
A bottomless sand filter is a special case of sand lined drainfield trench in which a 30 mil PVC lined
enclosure is designed and installed for con aining the distribution system and/or filter bed above grade.
It is quite similar operationally to an intermittent sand filter,but is not lined on the bottom. A
bottomless sand filter is selected typically to utilize more suitable soils high in the soil profile for
dispersal and treatment. The enclosure for the filter bed must be designed by a professional engineer if
the containment walls are over four feet in height measured from the bottom of the footing to the top
of the walls. See Figure 4. APPROVED

'Installation & System Notes
1. Installer must contact designer for final inspection of the installation prior to cover. All components, including tanks, lids,
transport line, drainfield,and water lines must be open for inspection. A$350.00 fee will be charged for time involved with the
inspection of the installation and creation of the record drawing. The designer reserves the right to charge additional fees if
multiple visits are needed due to installation errors or inaccessible components.
2. This septic design must be installed by a certified installer with the local health department. All components shall be installed
i according to state,county, and manufacturer requirements. For Homeowner Installs,the owner must get approval from the
designer and local health department prior to attempting installation.
3. Designer is not a surveyor. Installer must familiarize themselves with property line locations prior to installation. Any
confusion or conflicts with line locations should be reported to the property owner. A licensed surveyor may be necessary prior
to installation to confirm all line locations. Any discrepancies found must be reported to the designer immediately.
4. Drainfield area may only be cleared by a licensed installer familiar with sensitive drainfield area preservation. The builder, lot
developer, or property owner shall not clear the drainfield area. Any clearing required for drainfield installation shall not
remove or disturb any top soil in Primary and Reserve areas. Removal or disturbance to drainfield soils could render design
5. The property owner and installer are responsible for locating all underground utilities(ex. water,gas, electric) prior to
installation. Any utility locations shown within design drawings are likely approximate and may not be exact.
6. All proposed tanks must be installed on original soils or compacted gravels. Extend all tank connection lines out onto original
soil to avoid settling issues. Risers and lids must be brought to finished grade and left accessible for future operations and
rnainienance. Component manufacturers (ex. ATU,Glendons,) may have other requirements not listed within this design.
7.All electrical wiring shall be done by a licensed electrician or homeowner(if allowed) and must be permitted through Labor
and Industries.
8.The proposed septic system should be installed in dry weather conditions. Any failed attempts at installation during wet
weather conditions may render this design void.
l'iviaintain loft to waterlines with all septic components. If less than 10ft is required, sleeving in sch.40 pvc is required. If
sewage transport lines and waterlines must cross,waterline must be 18" above sewage line with one of the lines sleeved in sch.
40 pvc 10ft in each direction of crossing.
10.This design may include waiver applications with specific mitigation measures pertaining to installation,operation and
maintenance of the proposed components.
11. Stormwater runoff,footing drains, roof drains must be diverted away from any septic system components. No curtain,
foundation, perimeter drains shall be installed 30ft downslope and 10ft upslope of drainfield areas.
12. This design is site specific and intended to meet state and county requirements that are related to the system components
being proposed. Any placement of proposed buildings, proposed wells or other non-related items on these drawings may or
may not meet other requirements.

responsible for the continuous operation and maintenance of the system per WAC 246-272A. o bpq d aintenance
information, refer to Mason County Public Health Homeowner's Manual,which should be received after ins 1.
