One of the world’s leading engineering,
architecture and environmental consulting companies, GHD, has
developed innovative technology to continuously monitor water pump
efficiency in real-time.
The GHD Pump Efficiency Meter System has been developed through
a team from GHD’s Cazenovia operations, with support from the
company’s Innovation Program. It is designed to integrate
with existing pump control systems to optimise the use of a water
facility’s pumps and can notify operators when a pump’s performance
has deteriorated and requires maintenance.
We have just filed a patent application for this technology. The
system has the potential to save millions of dollars in wasted
energy at municipal water and wastewater facilities globally," said
Tom Devine, GHD’s Project Manager Energy Services for the East
It will also improve pump system reliability which will deliver
additional operational benefits.
"Most pump systems operate in a lead/lag configuration where a
lag pump only runs when the lead pump fails or cannot keep up with
demand. The problem with existing control systems is that they
don’t know why the lead pump can’t keep up - is the
pumping demand really that high, or has the capacity of the lead
"The key to GHD’s system is the algorithm that calculates pump
efficiency, which is subsequently compared to the expected
performance of a new pump operating under the same conditions. If
performance of a pump falls outside of an acceptable range, the
system places it into 'lag' mode and puts a more efficient pump
into the ‘lead’ mode, while generating an alarm.
"The causes of pump inefficiency are not typically visible to
the naked eye and existing pump control systems do not generate
alarms or warnings until there is an actual pump failure. Our
system continuously monitors pump performance and generates an
alarm before there is a failure – allowing operators to be
proactive in their maintenance."
Program was launched in 2008 in response to changes in the
global infrastructure industry driven by issues such as resource
deficits and climate variability. The company recognised a need to
adopt a more structured approach to generating, collaborating on
and delivering great ideas.
