Delta V3 Dual Groundwater Sump Pump | Basement Waterproofing

The Delta V3 Groundwater Sump Chamber has been designed to work as part of a Delta Cavity Drainage Waterproofing System.

Water that enters the basement structure behind the Delta cavity drainage membranes is diverted to the sump chamber either by means of Delta Perimeter Drainage channels or via 110mm drainage pipes (known as Modular or 129 Detail drainage)

The spun bound chamber is designed to withstand external groundwater pressure without deforming, a problem that can affect cheaper sump chambers.

The Delta V3 Dual features two high performance pumps offering high levels of performance and security. If one pump fails, the system can continue to run. The pump station has been specifically designed for below ground applications.

This system is used in basements up to 100m2 and can also accept surface water from a lightwell of up to 12m2.

Our guide for the installation of Delta cavity drainage membranes can be found here.

How high can the Delta V3 Dual Pump to?

The Delta V3 Groundwater is used to discharge up to a height of 3metres.

32mm Class C pipe should be used to provide the discharge pipework.
