Drainage drainage – Ecological septic tank
DRAINAGE DRAINAGE – “Ecological septic tank”
It is used only in lighter soils. The waste water must be free of suspended solids. The distance between the drainage and the groundwater table should be minimum 1,0 m, and from the ground surface – minimum 0,5 m. On 1 the user of the cottage is assumed on average 10 m of drainage. The drainage pipes are covered with a layer of gravel (thickness 20 cm) on grain size from 1 do 5 cm. At the kinks, at endpoints and in longer runs at distances up to 25 m ventilation pipes are installed.
ATTENTION! If, in an individual plan for the development of a building plot, it is recommended to distribute sewage through drainage into the ground, this before obtaining the "building permit."” a permit from the Local Sanitary Inspection should be obtained for this drainage. Without the consent of TIS, it is not allowed to irrigate with sewage from a concrete septic tank.
