Taking the pressure off water wastage
Dunea supplies drinking water to approximately 1.2 million
clients in the south west of The Netherlands.
- Complete booster station design proposal and components,
including a Demand Driven Distribution pressure management
- 3 NB pumps (100-315/334, 3 x 400 V - 50 Hz) with a 30 kW EFF1
motor. A pump control (MPC-E 3 - 30) and 3 frequency converters
(CUE 30 kW).
Dunea needed to build a new boosting station with an
unconventional capacity range. The now completed installation,
named Booster Hillegom, normally operates at between 80 - 300 m3/h
with heads from 22 mwc up to 36 mwc. The average capacity
requirement for the station is 140 m3/h at 23 mwc; but in cases of
emergencies the booster station is required to supply 700 m3/h at
36 mwc.Dunea invited five pump suppliers to propose water
distribution installations capable of meeting their unusual needs.
They would eventually go with Grundfos with work beginning in
Grundfos was able to supply the complete booster station,
including the concrete pit and electrical work. The new station is
based on Grundfos' unique Demand Driven Distribution pressure
management system, in which water wastage and maintenance are
reduced by ensuring the system maintains only the pressure needed
to answer the actual demand.
Aside from being a low maintenance solution that fulfils the
very specific parameters, the new installation is highly efficient.
As Dunea Distribution Specialist Rob de Jong puts it: "The Grundfos
Demand Driven Distribution pressure management system fits exactly
into Dunea's Policy Intention for 2015: With its inherent features,
Demand Driven Distribution represents the most responsible way to
use energy in our systems - and gives us the means to monitor
