Lower energy costs in a high demand environment
EURAWASSER provides drinking water and sewage disposal for
around 800,000 people in eastern Germany and the Rheingau
- 60% greater pump efficiency and reduced energy costs
- A life cycle cost analysis
- 3 high pressure CR pumps, 2 well pumps
Improved efficiency at one of
its facilities by 60%.
facilities typically have exceptionally high energy demands
- and with energy prices continuing to rise, EURAWASSER is
always seeking new ways to reduce energy consumption in its many
EURAWASSER commissioned Grundfos to perform a life cycle cost
(LCC) analysis at its Lübzin plant. The goal was to identify where
energy savings could be made in a cost-efficient way.
The Grundfos service team analysed the site's water pumps then,
using evaluation software, compared the pumps' performance to those
possible with newer models. They found the existing pumps
were suffering from wear and tear, which increased impeller
clearance and took a toll on overall efficiency.
The service team suggested replacing the pumps with three clean
water high pressure pumps from the CR range and two well pumps from
the SP range.
Installing the new pumps has created annual energy savings of
11,376 kWh. This equates to annual operating savings of €1,593/year
and up to 60% greater pump efficiency. This means EURAWASSER's
investment will be paid back within four years. Not surprisingly,
EURAWASSER intends to perform LCC analyses at its other sites.
