Il problema invisibile delle perdite di acqua dalle tubazione sotterranee di tutto il mondo!

Water loss: the invisible problem affecting cities worldwide – infograph
Cities lose high percentages of water from their networks every year. Real losses – often due to old and leaky pipes – are a major factor in this loss, but pump technology developed by Grundfos & HT Hydro Technology can help!


The Grundfos DDD controller provides pressure management, gradual ramp-up and ramp-down, the cascade operation of up to six pumps, and monitoring and control with clear text messages. The DDD controller is available with application-optimised software for up to six pumps from Grundfos.

Described below are three different versions for different sizes of networks, but all pump types can be operated by the DDD controller, with substantial economical benefits.
