OUTLINE SPECIFICATIONS FOR MOUNDED SOIL POLISHING FILTER
1. Treated effluent from the mechanical aeration sump unit shall be pumped
Intermittently, or fed by gravity if the levels allow, to the distribution chamber
on the mound feeding the 5 percolation trenches. The raised mound shall be
1.3m in height throughout its area and consist of the topsoil from the site
supplemented by imported good quality topsoil. The mound shall measure 13m
x 13m and may be landscaped into the contours of the site.
2. The slope of the percolation trenches from the distribution chamber shall be 1
in 200
3. The length of each of the 5 percolation trenched shall be 10m. Total length
50m.
4. The separation distance between the percolation trenches shall be 2m (ie
2.5m centre to centre)
5. Percolation pipes shall be 100mm diameter smooth wall uPVC sewer pipes,
75mm centers along the pipe. Holes shall be checked before installation to
ensure they are free from debris.
6. The width of each percolation trench shall be 500mm.
7. The depth of each percolation trench shall be 600mm below the mound
surface.
8. Percolation pipes shall be laid on a 250mm bed of washed gravel, having
particles in the range of 8 - 32mm.
9. Pipe surround shall be washed gravel, having particle size in the range 8
32mm.
10. Pipe cover shall be 150mm depth of washed gravel, having particle size in
the range of 8 32mm.
11. Geotextile layer to be placed on top of this followed by 100mm topsoil to
top of mound.
12. Geotextile shall be in accordance with EN ISO 10319.
Access / inspection points and vents shall be provided for the ends of the
percolation pipes. Covers shall be visible and installed to prevent the
ingress of water. They shall be suitable for rodding and scouring purposes.
13. A surface land drain 1m deep shall be employed upslope of the raised mound
soil polishing filter and not closer than 2m to divert surface water away
from it and to lower the water table in this area.
14. Ensure that the well proposed for the site satisfies the minimum distance from
the percolation area (see next page).
