The Delta Dual V4 packaged pump station has been designed specifically to work in unity with the Delta cavity drained system (Type C waterproofing) to collect groundwater via a perimeter channel or modular drainage.

Delta Dual V4 is suitable for collecting groundwater from a 150m² basement that requires a head height of up to 8m. It is capable of pumping 12m² of surface area in addition to groundwater.

Delta Dual V4 includes chamber, all internal pipework, and two powerful Delta V4 submersible pumps.

It should not be used to collect grey water from showers and hand basins, or foul water from a water closet.
