Sewage water can be managed in the following ways:
a) for FAMILY drainage treatment plants:
classic drainage system
sand filter (vertical and horizontal)
hydrophytic beds
infiltration packages
b) for FIL D'EAU biological treatment plants:
classic drainage system
package-drainage system
absorbing well
discharge of sewage to a drainage ditch / watercourse
Calculators for selected infiltration systems based on drainage paths are presented below:

CLASSIC DRAINAGE SYSTEM
Number of permanent residents PE
Soil category A
- soil with very good permeability, dredged stone, gravel, coarse sand
Soil category B
- good permeability, medium and fine sand, loamy sand
Soil category C
- soil with moderate permeability, sandy loam
For the correct design of the drainage system for the FAMILY household sewage treatment plant, the infiltration system should be built up based on:
metres of the drainage path
m
amount of gravel
t
minimum distanse beetwen drainage paths
m
Please note – in accordance with regulations, the distance between the infiltration system and the ground water level of 1.5 m must be maintained!
