Detention period for plain sedimentation water tanks = 4 to 8 hours (without coagulations)
Detention period for plain sedimentation water tanks = 2 to 2.5 hours (with coagulations)
Detention period for septic tanks = 12 to 36 hours.

Fill and draw-type of sedimentation tank 24 to 36 hrs.
Continuous flow type 2 to 4 hr for CAS.
And 4 to 8 hrs for plain sedimentaton.
Continuous flow type 2 to 4 hr for CAS.
And 4 to 8 hrs for plain sedimentaton.
