Private Sewage Disposal Code 2018 of South Holland > 9 Mound Systems > 903 System Design > 903.5 Mound Dimensions > 903.5.5 Mound Widths
JUMP TO FULL CODE CHAPTER
The mound width for a bed system shall be determined by the following equation:
(Equation 9-6)
For SI: 1 foot = 304.8 mm.
The mound width for a trench system shall be determined by the following equation:
(Equation 9-7)
For SI: 1 foot = 304.8 mm.
where:
J = 3(D + F + G)SU
I = 3(E + F + G)SD
The upslope correction factor (SU) and the downslope correction factor (SD) shall be determined based on the slope in accordance with Table 903.5.5.
