ISOLATED DRAIN CHANNELS
When several pumps are used to dry an area, or when the wastewater has to travel a long way before ending up in the selected trap, it can be useful to create waste channels isolated with plastic sheaths, where all the discharges of the pumps used to depress the excavation area will end up. This solution allows a much higher flexibility and expandability of the system. The limit is linked to the space required for their construction, which is difficult to carry out in residential areas but excellent for isolated construction sites.
